3.0 Physical Description

Horizon Compact is an integrated Ethernet modem and microwave radio transceiver, housed in a rugged weatherproof housing. It is provided with two weatherproof connectors, Port 1 and Port 2. Port 1, copper 10/100/1000 Base-t, or optional optical interface, carries data and optional in-band management traffic. Port 2, copper 10/100/1000 Base-t, carries optional out-of-band management traffic only. When Port 2 is not in use, a weatherproo f protective cap is used to seal the port.

A BNC style connector, with protective cap, is provided for obtaining field strength readings during the antenna alignment process. The output voltage is linear, giving 1 mV per dB values e.g. -30 mV = -30 dB. It is also used for providing a radio muting signal in system redundancy applications.

A high power variant is available, which requires a sun shield to meet temperature specifications.

3.1 Cabling

Both copper and optical interface cabling is supported.

3.1.1 Copper Interface

Two, weatherproof, RJ-45 Ethernet connectors provide data and management connections to the unit over CAT5E cabling. Ethernet cables must be wired for a straight through connection (see Section 4.0).

One connector (GigE – Port 1) is for data traffic and optional in-band management. Power (-36 to -60 V DC) is provided by an optional mains power adaptor and supplied to the Horizon Compact using Power on Ethernet (PonE) techniques , which incorporates both power and network transient suppression (See Section 8.1). CAT5E cable length is restricted to 90 metres.

The second connector (Port 2) is solely for an optional out-of-band management connection, using an overlay network. If Port 2 is not being used (e.g. in -band management being used), ensure that the vacant connector is sealed by fitting a weatherproof cap.

3.1.2 Optical Interface

A weatherproof, military specification, multi-pin, connector is provided for Port 2, which includes the power feed. Port 1 has a weatherproof optical fibre connector. Single mode and multimode fibre options are available. As with the copper variant, Port 1 supports data traffic and optional in-band management and Port 2 is for optional out-of-band management only.

In the optical variant, power (-36 to -60 V DC) is fed to Port 2 via a short ‘Y’ adapter cable, which also includes a weatherproof, in-line, RJ-45 connector for connecting to the optional out-of-band management overlay network. The power feed wires (see Table 3-2 for recommended gauge ) are spliced into the adapter cable using weatherproof tap connectors. The power feed and Port 2 Ethernet cables (maximum length 100 m) are fed through a Transtector surge arrestor unit designed to protect power and network circuits from transients.

Horizon Compact Release 1. 01.01 Wireless Ethernet Product User Manual – Volume 1

Page 17

Physical Description

As an alternative, an existing AirPair ODU composite power and Ethernet cable assembly, which is compatible with the Horizon Port 2 connector, may be used, provided that the RJ-45 connector (grey CAT5) at the Transtector end is re-terminated to A T & T GigE standards. The same Transtector type used in an AirPair ODU installation may also be used.

Table 3-2 Port 2 Power Cable Wire Gauge

These values are true for all radio variants and based on a minimum voltage of 35 V DC at the Horizon.

Distance from Power Supply to Horizon Unit 50 m 100 m 200 m 300 m Minimum wire gauge required (AWG) 20 16 14 12

Note that the power wires in the AirPair ODU modem composite cable are 16 AWG, which supports the maximum length (100 m) when out-of-band management is employed using the combined CAT5 cable.

3.2 Lightning Protection

The Horizon Compact is protected from cable transients and power surges caused by lightning, or other sources, by means of internal surge arrestor components and external housing grounding points (See Section 8.0). For the copper interface variant, protection of the connected network is provided by a proprietary DragonWave PonE power integrator/surge suppressor unit, into which the Ethernet cables are plugged. The power integrator/surge suppressor is located outside the network equipment enclosure, close to the network switch/router connection point. The optical variant requires the power feed and the Port 2 management connection (if used) to be connected via a Transtector surge suppressor to protect power and network circuits.

3.3 Dual Polarity Radio Mount (DPRM)

The DPRM system allows two Horizon Compact units to be assembled to a single antenna. The antenna used is no different to that used for a single unit. One Horizon Compact unit is mounted for horizontal polarity and the other for vertical polarity. Both units can transmit and receive simultaneously. This allows a link to carry up to 800 Mbps of Ethernet traffic. Although both units can operate on the same frequency channels, with 30 dB isolation, it is recommended that different frequency channels be used for each unit.

3.4 Power Switch Radio Mount (PSRM)

For redundancy purposes, the PSRM allows two Horizon units to be mounted to a single antenna. Both units must be or iented for the same polarity and only one unit can transmit/receive at any one time. The PSRM looks similar to the DPRM shown in Figure 3-3, but has internal components that only allow one unit to transmit/receive at a time.

Note that redundant systems do not have to use the PSRM. Each may be separately mounted to their own antennas if desired. See Section 11.13 for more details.

The benefits of the PS RM are that only one antenna is required, reducing tower real estate requirements, reducing weight and minimizing wind loading.

Disadvantages include a 4 dB loss in signal when operating on the primary systems at each end of the link and an 8.5 dB loss in signal when a secondary radio is activated (one end running on Primary and other end operating on secondary).

4.2 Ethernet Cabling from Horizon to Ethernet Switch

For the copper interface, data cabling from the Horizon unit to the Ethernet switch consists of outdoor rated, shielded, Cat5E cables equivalent to Belden 7919A. The shielded cables require shielded RJ-45 connectors. Use of standard indoor unshielded RJ-45 connectors may result in poorly constructed cables, intermittent connections and data loss.

If Port 2 is not being used, ensure that a protective weatherproof cap is fitted to the port receptacle. The cables terminate in a Horizon Power on Ethernet (PonE) unit located outside of the building entry

point.

Note: Straight through Ethernet cables must be used between the PonE adapter and the Horizon. The use of a cross -over type will result in damage to the Horizon Compact unit.

The PonE unit contains surge arrestors and must be grounded according to local or regional Electrical Codes. Ethernet cables are connected between the PonE unit and the Ethernet switch or router.

Power for the PonE unit is supplied by 2-wire 16 AWG electrical wiring, carrying 48 vDC (-48 v or +48v) with a maximum current draw of 2 amperes.

4.3 Assembling the RJ-45 Connector

Weatherproof RJ-45 connector shells are used for connecting the CAT5E cable, leading from the poweron- Ethernet power supply and network connections, to the Horizon Compact. Cables and connectors may be purchased from DragonWave or may be constructed or supplied by the customer.

Two different styles of connector have been used in production. For Horizon serial numbers ending in “999” or less, an RJ45 “snap in” type in-line housing is used. For serial numbers ending in “1000” or higher a “push fit” style is used. Both styles are no t compatible and do not mate with the respective female connector on the horizon chassis.

4.3.1 “Snap fit” style

The connector shell must be assembled in a specific manner for it to correctly connect to the Horizon Compact unit. The CAT5E cable is terminated as a straight through connection with a shielded RJ-45 connector. This RJ-45 connector has to be assembled into the weatherproof connector shell oriented as shown in Figure 4-4.

This connector relies on a gland nut to hold the assembly firmly together. The CAT5E cable is threaded through all the components of the connector housing (see Figure 4-5) before the cable is terminated as a straight through connection with a shielded RJ-45 connector. Once terminated, the RJ-45 connector slides back into the connec tor housing which accepts the tab on the RJ-45 connector. Screw the ferrule into the connector housing as far as it will go, ensuring that the ‘O’ ring creates a tight seal with the connector housing. Slide the compression seal into the ferrule, noting that the keyways have to mate with channels in the ferrule. While ensuring that the RJ-45 connector is firmly seated in the connector housing, tighten up the gland nut to secure the complete connector assembly.

5.0 Powering the Horizon Compact

Before an active management session can be started on the Horizon Compact, power needs to be provided to the unit. Read this section completely before applying power to the Horizon Compact.

5.1 Copper Interface

The Horizon Compact with copper interface receives its power over the Ethernet connection to Port 1 using a DragonWave proprietary technique. To integrat e the power onto the Ethernet cable requires the use of the DragonWave Power on Ethernet (PonE) adapter. The DragonWave PonE adapter also includes transient and surge suppression components to protect the power supply and network from lightning induced surges and transients.

Note: The Horizon PonE implementation is proprietary and does not follow IEEE standards. CAUTION

Only use a straight-through Ethernet cable to connect the Horizon to the PonE/surge unit. Do not use a cross-over Ethernet cable otherwise damage to the Horizon will result.

PonE/Surge Unit

Figure 5-1 Connecting Power to the Horizon Compact – copper interface

CAUTION Connect the Horizon Compact unit to the PonE adapter correctly BEFORE turning on power.

1. Connect Port 1 of the Horizon Compact to the correct socket on the PonE adapter using a

straight through Ethernet cable (see caution above).

2. Connect the Ethernet port on the PC to the network input socket on the PonE/surge unit, using a straight through Ethernet cable.

Ensure that you have connected the PC and Horizon to the correct RJ-45 sockets on the PonE/surge unit (see diagram above).

3. Once the PC and Horizon Compact are connected to the PonE/surge unit, you may connect power to the PonE/surge unit. This will supply power to the Horizon Compact unit.

CAUTION Do not connect a PC or other network device (e.g. network switch) to the right hand RJ45 sockets on the PonE adapter. -48 V DC is present on these connectors which may destroy the connected device. Connect only a Horizon Compact unit to the right hand RJ-45 connectors.

5.2 Optical Interface

In the copper interface version, power is fed to the Horizon using PonE techniques via the Ethernet connection to Port 1. In the optical version, this is not possible, so power is fed via the connection to Port

2. Port 2 on the optical interface variant is equipped with a weatherproof MIL style multi-pin connector, which incorporates an Ethernet connection and a power feed (NOT PonE) connection. Connection to Port 2 is achieved using a short ‘Y’ adaptor cable, having an RJ-45 connector on one leg, and power tails on the other. The Ethernet connection to Port 2 provides for optional out-of-band management and the power tails allow a power feed to be spliced into circuit. Note that the Ethernet connection and power feed to Port 2 must be fed via a Transtector unit to protect the network and power systems from transients.

As an alternative, an existing AirPair ODU composite power and Ethernet cable assembly, which is compatible with the Horizon Port 2 connector, may be used, provided that the RJ-45 connector (grey CAT5) at the Transtector end is terminated as shown in Figure 5-3. The same Transtector type used in an AirPair ODU install ation may also be used.

6.0 Initial Configuration

There are a number of configuration steps that need to be carried out before the Horizon Compact can become operational. It is recommended that these steps be performed prior to mounting the system on the tower. These steps relate to:

• radio bands

• frequency channels

• IP address information

Once this information has been correctly entered, the Horizon Compact system is ready for installation and system alignment.

The Horizon Compact can be configured using Telnet or the Web interface. Before attempting to log on you must configure the network parameters of your laptop, or PC, so that they

are in the same domain as the Horizon Compact default IP address and subnet mask values. By default, the IP address of a Horizon Compact system is 192.168.10.100 and the subnet mask is set to

255.255.0.0. Use this IP address to communicate with the unit, using either Telnet or the Web browser. A complete set of CLI commands is available for use with Telnet (See Appendix A).

For the copper interface, connect your laptop or PC Ethernet port to Port 1 (GigE port) on the Horizon Compact using a straight through Ethernet cable. For the optical interface, you will need to connect your PC to Port 1 of the Horizon via an optical switch. By default the management option is set to “inband” , which will allow management through the Port 1 data port.

Note: If the management interface type happens to be set to “out-of-band”, management through Port 1 (GigE port) will not be possible. In this case connect your laptop or PC to the Horizon Compact via Port 2. In both copper and optical Horizon variants, Port 2 has a copper interface.

6.1 Logging On

Secure management access to the Horizon Compact is controlled by a user name and password. The default Super User name is “energetic” and the default password is “wireless”.

Note: The Super User name (and other users) and password can be changed, but it is recommended that they are not changed until the radio link is properly configured, aligned and capable of carrying traffic. User accounts c an only be changed using Telnet access.

6.1.1 Using Telnet

From the DOS Command Prompt, or from the Windows Run option, type:

telnet 192.168.10.100 and press Enter.

When the Telnet window appears press Enter again to reveal the logon prompt. When prompted, enter the Super User name “energetic” and password “wireless”. Successful logging on is indicated by the CLI cursor (->) being displayed.

Note that after 10 minutes of inactivity, you will be automatically logged off the system.

6.1.2 Context Sensitive Help

Full context sensitive help is available for all CLI commands. Type ? followed by a partial command to return a list of all commands that match the entry, with an explanation as to how each command is used. Type a command followed by ? to return a list of all variants of that command. See Appendix A – List of CLI Commands for an alphabetical list of CLI commands.

Horizon Compact Release 1. 01.01 Wireless Ethernet Product User Manual – Volume 1

Page 30

DragonWave Inc. 20

6.1.3 Using the Web interface

The Horizon Compact Web interface is disabled by default. You must use Telnet to enable the Web interface by issuing the CLI command set web server on press Enter.

Open a Web browser and, in the “Address” or URL field at the top of the page, enter the IP address of the Horizon unit (default is 192.168.10.100) and press Enter. If your laptop or PC has been correctly set up, you will be prompted for the user name and password. Type in the default Super User name “energetic” and password “wireless”. The Horizon Compact Home Web page will be displayed.

6.2 Configuring Radio Band and Frequency Channels

Both Horizon Compact units in a system (near and far end) have to be configured with the same radio band. Volume 3 of this manual lists all the radio bands supported by the Horizon Compact system. The radio band selected must match that for which the Horizon Compact units have been manufactured. Only those radio bands for which the radio can be configured are available for selection. The radio band will also be dictated in the wireless licensing documents.

Typical radio band configuration selections have the format “fcc23_3_50”, “etsi23_3_14” , “ul_fcc24_1_40” etc.

For licensed radio bands, the Horizon Compact units at each end of the link have different frequency banks allocated to them. One unit will be allocated the “LOW” bank and the other the “HIGH” bank. This is indicated on the label attached to each unit (LOW or HIGH). Wireless licensing documents will indicate at which end of the link each should be located. The radio part number, that is stored in the system, determines if it is a LOW or HIGH unit and automatically configures the correct frequency bank for each unit.

Note that Horizon Compact units designed to operate at unlicensed frequencies have the same type of radio at each end of the link and do not have a LOW or HIGH indication on their labels.

Each bank contains a number of frequency channels, of which only one will be selected. Once again the actual frequency channel will be dictated in the wireless licensing documents.

You also need to configure the system mode (determines bandwidth and throughput parameters). Use the following procedures to configure the radio parameters:

6.2.1 Using Telnet

1. Type the CLI command: get radio band and press Enter. The system will respond with

the currently configured radio band and a list of all supported radio bands

2. Type the CLI command: set radio band <radio band> and press Enter, where <radio band> is the required radio band

3. Type the CLI command get system mode and press Enter. The system will respond with the current mode plus a list of allowable modes for the selected radio band.

4. Type the CLI command set system mode <Horizon mode> and press Enter. The mode follows the format of hc< channel bandwidth >_< speed >_<modulation>. For example, for a 50 MHz channel bandwidth with average Horizon speed of 110 Mbps using 16QAM modulation, enter set system mode hc50_110_16qam . Note that for unlicensed frequencies the mode includes “ul” in the mode descriptor. For example hc40_ul_212_128qam.

5. Type the CLI command get system speed and press Enter. The current system speed will be displayed. This, by default, will be the maximum speed supported by your purchased licensed speed key. Note that the mode configured in step 4 will determine the speed available to the system and cannot exceed the licensed speed, regardless of the mode selected.

Horizon Compact Release 1. 01.01 Wireless Ethernet Product User Manual – Volume 1

Page 31

Initial Configuration

6. To reduce the throughput speed to a figure less than the licensed speed, use the CLI command set system speed <speed>, where<speed> is in Mbps and can be adjusted in 1 Mbps increments.

7. T ype the CLI command get frequency bank and press Enter. A list of frequencies is displayed.

8. Licensed only - Locate the frequencies on the displayed list that match those found on the wireless license documents, and note the index number/letter on the left of the list (case sensitive)

9. Unlicensed only – The displayed list will show “Go” and “Rt” frequencies. One end of the link must be configured with a “Go” frequency and the other configured with the corresponding “Rt” frequency . Either end of the link can be configured as “Go” or “Rt”.

10. Type the CLI command set programmed frequency <index number/letter> and press Enter, where <index number/letter> is the same as that found in step 8 for licensed, or step 9 for unlicensed, installations

11. Unlicensed only – Determine the size (in cm) of antenna to be used with your unlicensed system. Type the CLI command get antenna size and press Enter. The allowable antenna sizes are displayed, along with a corresponding index number. Note the index number that corresponds to the size of antenna to be installed.

12. Unlicensed only - Type the CLI command set antenna size <index number> and press Enter, where <index number> is the index number determined in step 11.

13. Type the CLI command save mib and press Enter. This command saves the entered information to memory, but does not yet apply it.

Note: You will need to issue the CLI command reset system to apply the changes and make them effective. Optionally, this can be left until all the initial configuration parameters have been entered before issuing the command (See 6.3.1 step 5).

6.2.2 Using the Web interface

1. From the Home page select the “Configuration” menu option and then select the

“Frequency and port configuration” option

2. Use the drop down menus on the Web page for entering or changing the radio band and the programmed frequency. For licensed systems, the frequency bank “txLow” or “txHigh” will be pre-determined (HIGH or LOW Horizon label)

3. Return to the “Configuration” menu and select the “System Configuration” option

4. Use the drop down menu to select the desired system mode

5. click on the “Save settings” button

Note 1: For unlicensed systems, you cannot configure antenna size using the Web interface. Note 2: You will also need to click on the “Reset system” button to make these entries effective.

Optionally, this can be left until all the initial configuration parameters have been entered before issuing the command (See 6.3.2 step 5).

6.3 Configuring IP Address Values

When shipped from DragonWave, the Horizon Compact is configured with a default IP address (192.168.10.100) and subnet mask (255.255.0.0). The default address is used to communicate with the Horizon Compact for initial configuration purposes, such as entering the IP address that the unit will have in the network to which it is to be connected. IP address information is entered in the following manner:

6.3.1 Using Telnet

1. Type the CLI command set ip address <nnn.nnn.nnn.nnn> and press Enter, where

<nnn.nnn.nnn.nnn> is the desired IP address in standard format

2. Type the CLI command set subnet mask <nnn.nnn.nnn.nnn> and press Enter, where <nnn.nnn.nnn.nnn> is the desired subnet mask in standard format

3. Type the CLI command set default gateway <nnn.nnn.nnn.nnn> and press Enter, where <nnn.nnn.nnn.nnn> is the IP address of the default gateway in standard format

4. Type the CLI command save mib and press Enter. This command saves the entered information to memory, but does not yet apply them.

5. Type the CLI command reset system and press Enter, followed by “Y”. This command resets the system and applies all the radio and IP changes just made. Note that resetting the system disrupts traffic.

Once the system has reset, you may not be able to communicate with it without changing your laptop or PC networking parameters to match the new IP address values programmed into the Horizon Compact.

Note that the reset system command is not always required when making configuration changes, but the save mib command is always required. Commands that require a reset system will be indicated on the screen.

6.3.2 Using the Web Interface

1. From the Home page select the “Configuration” menu option and then select the “IP

configuration” option

2. Enter the IP address, subnet mask and default gateway values, using standard format, in their respective fields

3. Click on the “Submit” button

4. Click on the “Save settings” button

5. Click on the “Reset system” button

Once the system has reset, you may not be able to communicate with it without changing your laptop or PC networking parameters to match the new IP address values programmed into the Horizon Compact.

The system is now configured and capable of passing traffic once the Horizon Compact units are attached to antennas, mounted at each end of the link and aligned.

Initial Configuration

6.4 Recovery of IP Address and Serial Numbers

In the event that the Horizon Super User name and password, or IP address has been lost, forgotten, or misconfigured, you will need to contact DragonWave. DragonWave Technical Support will provide the Merlin recovery utility that, using a proprietary protocol, can recover the configured IP address parameters and/or reset the Super User name, Super User password and IP address parameters to the factory default values (energetic, wireless; 192.168.10.100, 255.255.0.0). In addition it reports the system serial number.

The Merlin utility runs on a PC running the Windows operating system and requires a one-time-use recovery key provided by DragonWave. Proof of ownership and proof of authority must be provided before the key will be issued. When Merlin is invoked, the Horizon unit responds with the required information, which is saved in a text file, located in the same directory as the Merlin application.

6.5 Changing and Adding User Names and Passwords

User account names and passwords can only be configured using a Telnet session. Only the Super User can change or add user account names or passwords. There are three user account levels as shown in Table 6- 1

6.5.1 Changing the Super User Name and Password

It is recommended that the default Super User name and password be changed as soon as the Horizon Compact system is aligned and operational.

Note: When you change the Super User name and/or password, record the new values in a safe place. If you forget the new values, there is no way of retrieving them from the system. You will have to contact DragonWave to arrange a Super User reset (24 hour support number 613-271-7010, or

[email protected]).

To change the super user use the CLI command set super user and press Enter. Follow the prompts. When the new name and password have been accepted enter the CLI command save mib and press Enter. This will save the changes in non volatile memory. Failing to save the mib will result in changes being lost in the event of a power failure, or system reset.

The Horizon Compact unit clip mounts onto a range of antennas, providing a variety of gain and range options. The same mounting system is used for all s izes of antenna.

The Horizon Compact has four, integral, spring loaded, mounting clips. The antennas are provided with four mounting lugs, onto which the mounting clips attach. The antenna port and the waveguide adaptor of the Horizon Compact, push fit tog ether before the clips are set, and are weather-sealed with a lubricated ‘O’ ring located on the outside surface of the antenna port (lubricate with provided lubricant before assembling).

7.1 Polarity

Horizon Compact units that operate on licensed radio bands use a diplexer system to simultaneously handle transmitted and received signals to/from the antenna. In this case, both transmit and receive antenna elements must have the same polarity.

For unlicensed radio band units, an orthogonal mode transducer (OMT) is used to allow the radio to simultaneously transmit on one polarity and receive on the opposite polarity.

7.1.1 Licensed Radio Bands

Both Horizon Compact units must be mounted on the pole/tower oriented for the same polarization. i.e. both vertical polarization, or both horizontal polarization.

Caution

Cross-polarized radios or antennas result in the signal strength being 20 30 dB below expected RSL levels! Ensure both radios have the same orientation (vertical or horizontal).

Polarity Marker

The radio frequency polarity is indicated by an arrow molded into the Horizon Compact housing. Attach the Horizon Compact to the antenna so that the arrow points either vertically or horizontally, as required, when the assembly is attached to the mounting post or tower. With the arrow horizontal (pointing to the left) – horizontal polarity; with the arrow vertical (pointing upwards) – vertical polarity. For licensed frequencies, the required radio polarity is defined in your licensing documentation.

This Horizon unit is shown mounted for horizontal polarity (arrow horizontal)

Figure 7-2 Horizon Compact polarity marker

7.1.2 Unlicensed Radio Bands (UL24)

For unlicensed radio bands, regulatory bodies require that both radios in a link have to be crosspolarized. This means that the antenna polarity of the transmitter at one end of the link is vertical and the transmitter polarity at the other end it is horizontal.

The radio at one end of the link transmits vertically polarized and receives horizontally polarized, while the other end transmits horizontally polarized and receives vertically polarized.

Caution

For 24 GHz Unlicensed Band, radios MUST be cross-polarized i.e. Vertically polarized at one end and horizontally polarized at the other. It does not matter at which end either radio is installed.

The radio frequency polarity is indicated by an arrow molded into the Horizon Compact housing. Attach the Horizon Compact to the antenna so that the arrow points either vertically or horizontally, as required, when the assembly is attached to the mounting post or tower.

For unlicensed frequencies, one end of the link has to be vertically polarized and the other horizontally polarized (crosspolarized). It does not matter which end of the link has a specific polarization.

7.2 Antenna Location

For both licensed and unlicensed systems, antenna location, relative to nearby obstacles, is an important factor to consider when planning an installation. For systems mounted on buildings, roof edges and parapets, the roof surface itself, air conditioning plant, other antenna systems, walls and overhead objects are all considered potential obstacles. On tower mounted systems you must consider the proximity of other antenna systems and mounting hardware.

Near field effects, resulting from a number of minor radiation lobes normally found around antenna systems, can reflect off nearby objects and interfere w ith the normal reception of the radio. Reflected waves can also change their polarity. This is especially important for unlicensed systems.

Consider an unlicensed installation that transmits with vertical polarity and receives with horizontal polarity. If the near field vertically polarized transmitted signal reflects off an obstacle located too close to the antenna system, then the reflected signal changes its polarity to horizontal, which is the same polarity as the receiver. This causes the receiver to “swallow” the transmitted signal, resulting in receiver “swamping”, excessive noise and the inability to receive the signal from the far end of the link. Ensuring that obstacles and objects are not too close to the antenna system will avoid this problem.

As a “rule of thumb”, for both licensed and unlicensed installations, ensure that you maintain an angle of 45 degrees, or greater, between the far side of the highest part of an obstacle and the underside of the antenna.

Figure 7-3 illustrates this approach. Also, remember to apply this rule in all directions around the antenna, above, below and to each side. An exception to this rule can be applied when the antenna is positioned

12.5 m (40 ft) or more from the edge of a roof clear of obstacles (a roof edge is considered an obstacle). In this case the antenna need not be higher than 2.5 m (8 ft) above the roof surface. For more details on antenna placement for unlicensed systems refer to Volume 2 of this manual.

7.3 Pole and Tower Specifications

It is important that mounting posts or towers used meet the DragonWave specifications for rigidity to minimize the effects of twist and sway on the alignment of the link. Note that the maximum twist and sway angle allowable is equal to half of the antenna beam width.

Grounding

8.0 Grounding, Power and Surge Arrestors

The Horizon unit must be grounded using a minimum of 6 AWG copper wire attached to any of the eight ground points available on the Horizon case, as shown in Figure 8-1.

Surge arrestors and lightning protection is built into the Horizon unit. The Ethernet and PonE cables must be properly protected at the end of their run as they enter the

building. Before Ethernet cable s enter buildings, voltages shall be clamped down to SELV by approved type primary protectors.

For the copper interface option, proper use of the Horizon PonE unit provides lightning and surge protection for the connected network. The PonE unit shall be installed according to local Electrica l Safety Codes.

For the optical interface, proper use of the Transtector unit protects the optional management Ethernet connection (if used) and the power supply.

Use 6 AWG or larger copper wire to connect from Horizon case grounding point to ground. There are two grounding points on each of the four sides of the Horizon case.

Figure 8-1 Horizon Compact case grounding point

Grounding, Power and Surge Arrestors

8.1 Power on Ethernet (PonE)

The copper interface variant of Horizon operates on -48 VDC and employs a proprietary Power on Ethernet solution. The Horizon Power on Ethernet surge arrestor unit provides integration of -48 VDC and the two straight through Ethernet cables.

Note: The Horizon PonE implementation is proprietary and does not follow IEEE standards. The surge arrestor uses RJ-45 connectors for the Ethernet cables and screw -terminals for the -48 VDC

power connections. Dual -48 VDC power connectors are provided, allowing for the connection of redundant power supplies.

The surge arrestor unit contains protection against cable transients and power surges caused by lightning or other sources. The surge arrestor is installed at the opposite end of the Cat5E/ PonE cables to that of the Horizon unit and protects the network.

To ensure adequate lightning protection, the PonE surge arrestor unit must be properly grounded.

CAUTION

Serious damage to network switches or route rs can occur if the network is plugged into the connectors marked “TO HORIZON UNPROTECTED”. Power is fed to the Horizon unit along the same wires that carry Ethernet traffic to the Horizon unit. Do not, under any circumstances, plug cables connected to the network into the RJ-45 connectors marked “TO HORIZON UNPROTECTED”.

CAUTION

Only use straight through Ethernet cables to connect the PonE adapter to the Horizon Compact. Using cross-over

cables will result in damage to the Horizon Compact unit.

CAUTION

Connect the Cat5E cables to the Horizon Compact BEFORE applying power to the PonE surge arrestor unit.

Horizon consumes a nominal 20 Watts (standard power), or 40 Watts (high power variant) from the -48 VDC supply. All eight of the wires in the Ethernet cable are used to carry power to the Horizon Compact unit. The Power on Ethernet surge arrestor unit is rated at 2 amps.

9.0 Preparing for Alignment

The Horizon Compact and antenna assembly is attached to the mounting post, or tower, with a specialized mounting bracket that allows fine orientation adjustment of the Horizon/antenna assembly. The same mounting bracket is used for all ante nna sizes.

Visual alignment is achieved by rotating the assembly on the post, or tower, and positioning the assembly so that the antenna is visually aligned with the target system before tightening the mounting bracket clamp. Final alignment is achieved us ing the azimuth and elevation adjustment bolts. Once alignment is achieved, the adjustment mechanisms are locked in place with lock nuts.

Figure 9-1 Mounting bracket with fine adjustment bolts

Final alignment is achieved by monitoring the received signal level (RSL) values as the system is adjusted for azimuth and elevation. The BNC Field Strength Monitor connection is used in conjunction with a voltmeter for RSL monitoring. See Section 9.1. Adjustments are made until the RSL value is at a maximum, which should be within ± 3 dB of the expected value (link budget figure).

9.1 Received Signal Level (RSL) Measurements

To accurately align the Horizon Compact to its far end peer, you need to monitor the received signal level (RSL). There are two recommended methods for monitoring RSL. These are:

1. Use the CLI command set alignment on to activate the alignment feature at the BNC connector located on the side of the unit. Connect a voltmeter to the BNC connector. The voltage at this connector is linearly related to RSL and is 1 mV per dB e.g. -45 mV = -45 dB. Note that the centre connection on the BNC connector is positive, so to read negative values (to correlate with the negative RSL values) connect the negative pole of the voltmeter to the centre connection.

Figure 9-2 Voltmeter connections to BNC field strength monitoring connector

connector

jacks cables are available from your voltmeter dealer, or can be constructed by the

user.

2. Alternatively, readings can be made remotely via the Web interface, using the Tools – Link Alignment menu option. An operator would then have to continually relay RSL readings, via a radio or cell telephone, to the rigger adjusting the positioning of the system.

9.2 Three Important Factors

When you prepare to align the radio antennas , you must consider three important factors:

1. the radiation patterns of dish antennas (main lobe and side lobes)

2. the need for a Clear Line of Sight (LoS)

3. the sensitivity of the alignment adjustment

9.2.1 Antenna Radiation Patterns

The dish antennas used for the DragonWave Horizon Compact have high gains and very narrow beam widths, making antenna alignment a critical element of a successful installation. In addition to the main antenna beam, or lobe, there are often side lobes. Care must be taken to ensure that alignment is made to the main lobe and not onto a side lobe. If you align onto a side lobe, the RSL will be at least 20dB less than expected.

9.2.2 Clear Line of Sight (LoS)

The DragonWave Horizon Compact requires a clear LoS between the units at each end of the link. You must be able to see an unobstructed view of the antennas from each end. Avoid obstacles that are close to the LoS mid-way between antennas, but not blocking it, as this can have a negative impact on signal quality (Fresnel zone clearance). Also, ensure that antennas are mounted with adequate clearance from roof tops, roof edges, walls and other obstacles (e.g. air conditioning plant) to avoid problematic near field effects.

9.2.3 Alignment Adjustment Sensitivity

When aiming the antenna it cannot be over emphasized that you must rotate the adjustment nut(s) 1/10th of a turn at a time between taking RSL readings (allow time for the RSL reading to update). One full turn of the adjustment mechanism can move the antenna through 1.6 degrees azimuth or 2.2 degrees of elevation. Table 9-1 shows that the beam width of the typical antenna is often less than the amount of movement available with one full turn of the aiming adjustment.

10.0 Aligning the Antennas

Follow the steps of the alignment procedure shown below . Note: ensure that the CLI command set alignment on has been entered at both ends of the link if you are using the BNC connector to measure

field strength.

At the first end:

1. Loosen the pan mechanism lock nuts

2. Pan or move the antenna horizontally across the entire range of adjustment to identify

the main lobe and the side lobes. The main lobe is approximately 2 degrees in width (depends on frequency and antenna size). The two major side lobes are approximately 5 degrees apart. Adjust the antenna to the main lobe (approximately).

3. Tighten the pan mechanism lock nuts and loosen the tilt mechanism lock nuts.

4. Tilt or move the antenna vertically until you receive the strongest RSL reading.

5. Tighten the tilt mechanism lock nuts and loosen the pan mechanism lock nuts.

6. Pan or move the antenna horizontally to locate each of the lobes. Record the RSL

values of each. Select the strongest RSL recorded and readjust the antenna to this strongest RSL reading.

7. Re-tighten the pan/tilt mechanism lock nuts to lock the antenna in place.

At the other end:

8. Repeat steps 1 through 7

Return to the first end:

9. Loosen the pan mechanism lock nuts.

10. Pan or move the antenna horizontally across the entire range of adjustment to identify

the main lobe and the two major side lobes. Adjust the antenna to the main lobe (approximately).

11. Tighten the pan mechanism lock nuts and loosen the tilt mechanism lock nuts.

12. Tilt or move the antenna vertically until you receive the strongest RSL reading.

13. Tighten the tilt mechanism lock nuts and loosen the pan mechanism lock nuts.

14. Pan or move the antenna horizontally and locate the strongest RSL reading.

15. Re-tighten the pan/tilt mechanism lock nuts to lock the antenna in place.

16. Repeat steps 1 through 15 as necessary to obtain maximum RSL reading.

Notes:

The RSL level should be within ±3 dB of predicted levels. Factors that contribute to low RSL levels are:

• incorrect antenna alignment - aligned to a side lobe and not main lobe

• improper polarization of antennas – one end horizontal and the other vertical

• path issues - obstructions such as trees, hills, or buildings within the beamwidth

• path clearance issues such as diffraction, partial obstruction, Fresnel zone issues

Preparing for Alignment

10.1 Signs of a Healthy Link

You can be confident that a link is properly aligned and free of problems if the following readings are obtained during a Telnet or Web interface session with each end of the link :

• No alarms – use the CLI command get alarms and press Enter to return a list of current alarms – should be none that cannot be explained by network status

• Received signal level (RSL) within ±3 dB of link budget figure in clear weather. Use the CLI command get modem statistics and press Enter to obtain the RSL reading. The Unchannelized power reading should be within 6 dB of the RSL reading. If the Unchannelized power drops below -75 dB, then it is likely that there is no signal being presented at the radio portion of Horizon Compact. Check alarms.

• Eb/No of 19 dB or higher – use the CLI command get modem statistics and press Enter to display the Eb/No value

• Signal to Noise Ratio (SNR) of 24 dB or higher – use the CLI command get modem statistics and press Enter to display the SNR value

• Equalizer Stress typically between 20 and 30, but never more than 150 - use the CLI command get modem statistics and press Enter to display the Equalizer stress value

• Modem Block Error Rate 0.00e+00 – use the CLI command get traffic statistics and press Enter to display the Modem Block Error Rate. Modem block errors are an indication of loss of data frames. Note that there are residual modem block errors as a result of the alignment process.

• Transmit power typically set at the maximum for the radio band used – use the CLI command get transmit power and press Enter to return the configured transmit power

• All sections operational – use the CLI command get health and press Enter to return the health status of all three sections of the system

The readings obtained using the CLI commands during a Telnet session can also be retrieved using the Web interface. All items listed here are available on the left- hand pane of the Web interface and appear on each Horizon web page.

11.0 Advanced Configuration Features

DragonWave Horizon Compact has a number of optional advanced configuration features that may be applied if desired. It is recommended that they only be applied once the Horizon Compact is satisfactorily aligned and successfully carrying traffic. The following lists the features available:

• Radius Server User Authentication • Threshold Alarms

• VLAN Tagging • Rapid Link Shutdown (RLS)

• 802.1P Priority Tagging

• Horizon Throughput Speed • Adaptive Modulation

• Adaptive Transmit Power Control

(ATPC)

• Modem Authentication

Each feature is described in this manual, but detailed configuration information for each can be found in the Horizon Product Manual Volume 2 - Advanced Features.

11.1 RADIUS Server User Authentication

The DragonWave Remote Authentication Dial In User Service (RADIUS) server option enables users to be centrally authenticated before being allowed access to a Horizon Compact unit. This adds another layer of security by removing user access control away from individual units and moving it to a central server. However, all Horizon Compact units must have all approved users entered in the user authentication list before the system will grant access at the appropriate user levels (admin, NOC, Super).

Up to five (5) RADIUS servers can be configured. When one, or more, RADIUS server is configured, the username and password authentication system on

the Horizon Compact is bypassed, in favour of the RADIUS system. Access levels are still retained in the local Horizon Compact memory, so once a user is verif ied by the RADIUS server the access level is assigned by the Horizon Compact (provided that that user is a valid user on that unit). Any user that is validated by the RADIUS server, but is not found in the Horizon Compact user authentication list, can gain access to the unit but only at an admin user level.

If, on attempting to log in, a user does not receive a response from a configured RADIUS server, the user will not be allowed to log in.

Only the Super User can issue any of the RADIUS “set” commands a nd view any of the security related entries returned with “get” commands (passwords, shared key etc..)

• Simple Network Timing Protocol (SNTP)

• Radio Redundancy

Advanced Configuration Features

11.2 Management VLAN Tagging

Note: The configuration of Horizon Compact VLAN tagging is only necessary if you wish to restrict Horizon Compact management communications to a specific management VLAN.

The Horizon Compact system will pass user VLAN traffic transparently, independent of the Horizon Compact VLAN settings. The VLAN settings are for Horizon Compact management purposes and do not affect user data or traffic. VLAN Standard IEEE 802.1Q is supported for Horizon Compact VLAN tagging and it accommodates up to 4096 VLANs within the “8100” VLAN range. Note that the Horizon Compact system handles Ethernet frame sizes up to 9600 bytes.

There are three pa rameters associated with Horizon Compact VLAN tagging:

1. Enable or disable VLAN tagging (set VLAN tagging [on/off])

2. Identify the VLAN tag id to be used with Horizon Compact (set VLAN tag [tag id])

3. Determine whether to allow Horizon Compact to match the VLAN settings in response to

incoming frames, or whether to restrict responses to those incoming frames containing the programmed VLAN tag. There are two modes (set network protocol strict [off/on]) which are commonly known as “friendly” and “strict” mode.

i. “Friendly” mode. In this mode, Horizon Compact matches the VLAN format of

the incoming frame. If an incoming frame contains a VLAN tag, then Horizon Compact responds with a VLAN tag matching the incoming frame. If the incoming frame does not contain a VLAN tag then Horizon Compact does not insert a VLAN tag in the response. Frames generated by Horizon Compact (e.g. SNMP traps) will contain the programmed VLAN tag.

ii. “Strict” mode. Horizon Compact will only respond to frames containing the

programmed VLAN tag. All other frames will be ignored. Frames generated by Horizon Compact (e.g. SNMP traps) will always contain the programmed VLAN tag.

11.3 802.1P Priority Queuing Implementation in Horizon Compact

QoS implementation is best done on the ingress and egress portions of the transport network. As such, QoS should be implemented on the Ethernet switches. Once that implementation is in place, the Horizon Compact can be configured for QoS, should the potential for congestion exist. Enabling CoS/QoS (802.1P) on Horizon Compact ensures that the high priority traffic is delivered at the expense of lower priority traffic.

Horizon Compact supports the eight Class es of Service (CoS) levels (0-7) defined within 802.1P. There are four CoS Queues within Horizon Compact, numbered 1 to 4. Any of the eight CoS levels can be assigned to any of the four Horizon Compact CoS Queues. Horizon can also be configured to use the priority bits found in the DSCP field of IP headers. Any frames not having an IP header can be classified based on the default class of service value (set cos default value [0 though 7]).

There are three additional Horizon Compact settings that can be used to customize the data flow to match network requirements:

1. CoS Committed Information Rate (CIR), which de termines the guaranteed bandwidth allocated to a particular Queue.

2. CoS Committed Burst Size, which determines the amount of burst data the Queue can manage.

3. Expedite Queuing (see Section 11.3.3), which allows a Queue to be set as a priority Queue

whereby it delivers its data at the expense of other non -Expedite Queues.

Horizon Compact Release 1. 01.01 Wireless Ethernet Product User Manual – Volume 1

Page 56

DragonWave Inc. 46

11.3.1 Operation with 802.1P Priority Queuing Disabled

If 802.1P filtering is disabled in the Horizon Compact system, all incoming frames are treated equally and are forwarded on a first-come first-served basis. The system operates in a FIFO (First In First Out) basis.

If the Pause Frames feature (see Section 11.4) is enabled, pause frames will be sent to the connected switch when the input buffer is close to being full (internally set threshold). This allows time for the queue to empty prior to more frames being received and thus avoids congestion.

11.3.2 Operation with 802.1P Priority Queuing Enabled

If 802.1P filtering is enabled in the Horizon Compact system, the scheduling mechanism can be

described as follows:

1. Select the highest priority queue which has a frame in it

2. Send that frame

If COS CIRs are set for the queues, then the scheduling mechanism can be described as follows:

1. Select the highest priority queue which has a frame in it, and hasn’t used up its CIR budget

2. Send that frame

The operation of the Scheduler is affected by both the user-configurable CIR and CoS Queue PBS settings.

If the Pause Frames feature (see Section 11.4) is enabled, pause frames will be sent to the connected switch when the input buffer is close to being full (internally set threshold).

The Horizon Compact system also allows any frames without a VLAN tag to be allocated an 802.1P CoS level (“set untagged frame priority”). If the “set untagged frame priority” is not configured, then all untagged frames will be forwarded through Queue 1.

Horizon Compact is also able to manage Q- in-Q or Super VLAN traffic. The system can be configured to use either an encapsulated frame’s priority tag or the encapsulating frame’s priority tag, in determining priority handling.

11.3.3 Expedite Queues

Expedite Queuing is a mechanism that allows one or more of the four Queues to transmit its data as priority traffic, at the expense of the remaining Queues. When Expedite Queue is enabled, then as long as there is data in the Expedite Queue, or Queues, that data will be transmitted first . This allows time critical or error-sensitive traffic to have priority data delivery.

As network services increase, the need for multiple Expedite Queues becomes evident. A network administrator may require three Expedite Queues and decide to send all network routing protocols through the highest Expedite Queue; send IP Voice through the next highest Expedite Queue; send Video over IP through the next highest Expedite Queue and send all other traffic to the remaining Queue, which is not configured as an Expedite Queue. To do this, the administrator would configure Queues 4, 3 and 2 as Expedite Queues and configure Queue 1 as a standard Queue with a particular CIR. Configuring the CIR for a particular queue to 100% enables the expedite function for that queue.

11.3.4 Management Traffic

Slow Ethernet services and multicast frames are handled by a special Queue inside the Horizon Compact. The Queue is not user-accessible. It works similar to an Expedite Queue in that it ensures management traffic is passed through in an “expedited” fashion. It does not affect, nor is related to the 4 Queues within Horizon Compact. This Queue does not impact the operation of the 4 user-configurable

802.1P Queues.

Horizon Compact Release 1. 01.01 Wireless Ethernet Product User Manual – Volume 1

Page 57

Advanced Configuration Features

Average

Threshold

Frames destined for the 01-80-C2-00-00-xx MAC addresses are sent to the internal Queue. Examples: STP, RSTP, MSTP LACP, Pause Frames, GARP (GMRP,GVRP), bridge broadcasts, OAM, LLDP, Port based authentication are all sent to the internal Queue and are transmitted in an expedited fashion. Other frames that the user determines must be treated in an expedited fashion, such as “keep-alive” frames and MRP frames, must be assigned a CoS within the switch, then assigned to the appropriate Queue within Horizon Compact.

11.4 Pause Frames

Pause frames are generated by the weaker (slower) link when its forward pipe gets full. Pause frames inform the upstream device to “pause and stop sending traffic for a period of 5 msec”. When the Pause Frame feature is enabled, Horizon Compact generates pause frames to the Ethernet switch when the Horizon Compact receiving buffer hits the internally set threshold. The receiving buffer threshold is close to 100 msec at GigE rate. At data rates lower than GigE, the data buffer will accommodate a lesser amount of data. The Pause Frame feature can be used when CoS/QoS is enabled or disabled.

11.5 Horizon Compact Throughput Speed

When you purchase a Horizon Compact system you receive a unit capable of giving a throughput speed of up to 400 Mbps. However, the actual throughput speed achievable for any given system depends on the specific throughput speed key that you purchased with the system

You can upgrade your system to a higher licensed throughput speed (up to 400 Mbps) by purchasing an upgrade key and reprogramming your system. Any upgraded system can be reconfigured to a lower throughput speed as required, without losing the ability to return to the upgraded speed.

You may also downgrade a system to a lower licensed speed. A downgraded system may warrant a refund of licensing fees. A downgraded system cannot be returned to its former higher licensed speed without purchasing another licensed upgrade key.

11.5.1 Maximum Throughput Speed

The maximum throughput speed is determined by the Horizon Compact throughput speed key you purchase, however, it is important to note that this is also determined by the Channel bandwidth associated with the configured radio band, and the modulation scheme used. The channel bandwidth is a function of the radio band, and the modulation scheme is automatically selected depending on the desired maximum throughput. Configuring the Radio Band and System Mode of the system determines the maximum throughput and hence determines the modulation scheme applied.

Note: if you set a System mode of hc50_110_16QAM, the 110 figure indicates the maximum throughput speed capability of that mode. However, if your licensed throughput speed key purchased from DragonWave is less than this figure, your system throughput will be limited to the purchased licensed throughput speed. Table 11-1 shows the modulation schemes that are selected for various Operating Modes when 23 GHz radio band with 50 MHz channel spacing is configured.

11.6 Adaptive Transmit Power Control (ATPC)

Adaptive Transmit Power Control (ATPC) allows a Horizon Compact system to adjust its transmit power to compensate for far end signal loss caused by changes in atmospheric conditions e.g. heavy rain. ATPC maintains the RSL at -50 dB and adjusts the transmit power by up to 20dB as necessary in order to maintain -50 dB during fade conditions.

RSL threshold levels that trigger power changes, the maximum power change allowed, and a hysteresis factor are preset at values which optimize the operation of the Horizon Compact system. A fade factor of 5dB/second can be handled.

The Horizon Compact system is able to discriminate between RSL levels that ar e reduced as a result of interference and those as a result of genuine path loss, so that ATPC is not invoked unnecessarily.

Some jurisdictions require the use of ATPC so that power levels are kept as low as possible when wireless communication conditions are good. When ATPC is to be used, if it can be shown that the maximum power of the system would be used only on infrequent occasions, some jurisdictions will allow a lower power level to be used in the calculations that determine interference criteria. Th is offers some advantage to the installation. This lower power is termed the “coordinated power”. The DragonWave ATPC feature supports a coordinated power parameter.

ATPC is enabled or disabled by issuing the CLI command set atpc [on/off][coordinated power] The current status of ATPC can be determined by using the CLI command get atpc status .

Note: If ATPC and Advanced Adaptive Modulation (AAM) are both enabled, when AAM is invoked i.e. modulation scheme switched to a lower level, ATPC is automatically disabled until AAM restores the original modulation scheme.

11.7 Horizon Compact Authentication

This feature is only necessary if you wish to restrict communication from a Horizon Compact unit to a specific peer or to a group of Horizon Compact units. Authenticat ion is generally used as a security measure. It is not recommended to enable Authentication prior to alignment of the radios.

Authentication restricts a Horizon Compact unit from communicating with other Horizon Compact units unless the other units match an authentication string. There are three types of authentication:

1. No Authentication

2. Unique Authentication

3. Group Authentication

A new Horizon Compact system in line with the signal cannot authenticate and receive data if another Horizon Compact system is already authenticated. The system authenticates its peer(s) at an interval of approximately five seconds.

The Horizon Compact node does not accept data from other manufacturers’ systems.

11.8 Threshold Alarms

Horizon Compact provides Threshold Alarms to assist in managing the performance of the system. Threshold alarms are available for the following parameters:

With the exception of SNR, each Threshold Alarm has two associated parameters:

The combination of the value and the time limit is user defined. The proper combination of the two parameters will prevent fal se alarms from occurring.

* For the SNR parameter, only the threshold level can be set, the time limit, or hysteresis, being a preset value.

1. RSL (Receive Signal Level)

2. Bandwidth Utilization

3. Dropped Frames

4. Signal To Noise (SNR) *

1. Threshold value

2. A time limit over which the Threshold value must be exceeded before the alarm is

reported.

11.9 Rapid Link Shutdown

It is often desirable to signal or detect network link issues in the quickest manner possible. This is especially true when running Layer 2 redundancy protocols, such as Spanning Tree and Metro Ring protocols. Signalling to the network is done by shutting down the Ethernet data port(s) connecting the Horizon Compact to the network. The Rapid Link Shutdown (RLS) feature provides this functionality.

Some situations that would result in Rapid Link Shutdown include:

• Link outage. Should a power failure or a complete loss of link occur then Ethernet ports at both

ends of the link can be shut down

• Far-end Ethernet connection problems. If the remote unit data Ethernet port is disconnected or

disabled, the near-end unit will also shutdown it’s Ethernet port

• Link quality problems. If the link quality (error rate) reaches user programmable thresholds the

Horizon Compact Ethernet ports can be shut down

• Horizon Compact configuration or hardware failure. If hard faults, such as a hardware failure,

interrupt the link, both Horizon Compact Ethernet ports can be shut down.

11.10 Configuring the Time Source (SNTP)

Date and time information can be entered into the system using CLI command set date time [dd/dd/yyyy hh:mm:ss:ms] press Enter.

The date and time settings in Horizon Compact are not maintained if a power outage is experienced. To ensure that set system date and time are always accurate, the system can poll known time sources and update time information on an ongoing basis.

Up to five time sources can be configured, which can provide accurate time and date information to the system. Simple Network Time Protocol (sntp) is used. Either an Internet time source or an NTP server on your network may be used.

Five time sources are configured by default (see Table 11-2). Each time source is indexed 1 to 5. Indices 1 and 2 are from Industry Canada servers, 3 and 4 are from U.S. Navy servers and 5 is from a Swiss server. Any other time sources can be configured. The timing information is polled every 60 minutes.

11.11 Automatic Adaptive Modulation (AAM)

The two principal modulation schemes used on the Horizon Compact system are QPSK and QAM. QPSK (the lowest modulation scheme) is ideal for long distance, but has the lowest throughput capability.

Higher throughputs are achieved by using more complex modulation schemes e.g. 16-QAM, 32-QAM, 64-QAM, 128-QAM, 256-QAM. The higher numbers indicate a progressively more complex scheme and a higher bandwidth (throughput) capability e.g. 256-QAM is more complex than 128-QAM and provides a higher throughput. More complex modulation schemes are susceptible to noise and thus require a stronger signal for the demodulator to accurately decode the data stream. Consequently, the more complex the modulation scheme used, the shorter the distance limitation of the radio link.

If a system is using a given modulation scheme and weather conditions cause signal levels to deteriorate below acceptable levels (risking a link failure), changing the modulation scheme to a less complex scheme, will allow the link to remain functional, although the throughput will be low er, until weather conditions improve. The modulation scheme can then be returned to the original scheme and the throughput returned to normal levels. The Horizon Compact system can be configured to automatically change modulation schemes if environmental conditions deteriorate to the point where a wireless link may otherwise fail. This feature is called Automatic Adaptive Modulation (AAM). Note that AAM cannot be invoked if RLS is enabled.

The current modulation scheme (determined by the configured system mode parameter) will switch to the lowest modulation scheme available (a number of system modes, which includes the modulation scheme, are available for any given radio band, see Section 6.2), if the Horizon Compact units detect errored, but corrected, frames (caused by reduced RSL levels) . The original modulation scheme will be restored once preset parameters indicate that conditions are suitable for returning to the original modulation scheme (and return to the original bandwidth). The total outage time due to modulation downshift is approximately 50 to 100 mS on average, with upshift down time at approximately 75 mS.

All radio bands available with the Horizon Compact support AAM.

11.12 Horizon Compact Throughput Doubling

Horizon units are capable of transmitting up to 400 Mbps. For higher data rates, an Ethernet switch that supports link aggregation is required. Horizon can be configured as 2 units, each with their own separate antenna, or the Dual Polarity Radio Mount (DPRM) can also be used to mount two systems to a single antenna (see Figure 3-3). The DPRM allows both systems to transmit/receive simultaneously, one with horizontal polarization and the other with vertical polarization, supporting load sharing or throughput doubling (up to 800 Mbps) (see Figure 11-1)

Figure 11-1 DPRM and Throughput Doubling

11.13 Horizon Redundancy

The Horizon system can be configured for redundancy using two physical options. One option allows for two separate Horizon units, each with its own antenna, and connected to an Ethernet switch configured with a re-routing protocol. The switch is responsible for re-routing the data to the redundant stand-by unit when a failure occurs. This option is termed the “two wire” option.

The second option has two Horizon units mounted on a Power Switch Radio Mount (PSRM) with the data feed from a single connection to a switch. Switching traffic to the redundant stand-by unit is determined and performed by the Horizon Compact system and not the connected switch. This option is termed the “single wire” option.

The configuration steps for each option are different (see Volume 2 for more details).

11.13.1 BNC Connector

The BNC connector on the side of the Horizon Compact serves a dual purpose. It can be configured as a source for field strength measurements during antenna alignment, or configured to provide a redundancy switch signal to a second Horizon Compact system mounted close by. For redundancy, the BNC connectors on both units are interconnected with a coaxial cable. Note that for redundancy to work, you must ensure that the field strength option for the BNC connector is turned off ( set alignment off).

When the Horizon system is configured for redundancy, a DC signal is presented at the BNC connector of the unit normally carrying traffic . Since the BNC connectors on both units are interconnected, the DC signal is passed to the stand-by unit. As long as the DC signal is present, then the stand-by radio is held

Horizon Compact Release 1. 01.01 Wireless Ethernet Product User Manual – Volume 1

Page 63

Advanced Configuration Features

in a hot stand -by state. When the DC signal is removed (as a result of the unit normally carrying traffic failing), then the stand-by radio becomes active, and takes over the traffic. After a redundancy switch, once the first system is able to return to carrying traffic, a manual switch is required, via a CLI command, to return the system to its original state.

11.13.2 Two Wire Option

The “two wire” option is so named because two separate data feeds are required; one to each Horizon system. One Horizon system is configured as the primary and the other as the secondary. Note that the terms “primary” and “secondary” relate solely to the internal functions of the units and has no relationship to which radio is in stand-by or which is carrying traffic. Management has to be via Port 2, so each Horizon will be configured for out-of-band management and have its Port 2 connected to the overlay management network.

Data re- routing, between the Horizon systems, is dependant upon a connected Ethernet switch. Ethernet switch settings are used to reroute the traffic from one Horizon unit to the other, when a failure occurs. Protocols such as RSTP, LACP and routing protocols are able to determine that the Horizon units have switched from active to stand-by units, or vice-versa, and will reroute the data traffic through the active link.

Horizon Compact Release 1. 01.01 Wireless Ethernet Product User Manual – Volume 1

Page 65

Advanced Configuration Features

11.13.3 Single Wire Option with the PSRM

The “single wire” option is so named because only one data feed is required to be connected to the two interconnected Horizon systems mounted on the PSRM.

The PSRM supports system redundancy by connecting two Horizon units to a single antenna. Only one of the radios of the mounted systems may operate at any one time. Both systems have the identical polarity, either both vertically or both horizontally polarized. One system is configured as the Primary and the other as the Secondary. Note that the terms “primary” and “secondary” relate solely to the internal functions of the units and has no relationship to which radio is in stand-by or which is carrying traffic.

Port 1 of the primary unit carries the data feed, with Port 2 of both units interconnected. Port 1 of the secondary unit handles management traffic. The secondary unit has to be configured for in-band management and the primary unit configured for out-of-band management.

Switching from the active unit to the stand-by unit is determined by the configuration of the Horizon Compact units and does not depend on connected Ethernet switches.

After a redundancy switch, once the first unit is able to return to carrying traffic, a manual switch is required, via a CLI command, to return traffic to the first unit.

12.0 Horizon Management

The Horizon Compact system can be fully managed locally or remotely. Horizon Compact supports Telnet access, SNMP management and a Web interface accessible through the IP network. The entire Command Line Interface (CLI) command set is available through Telnet. The entire list of system parameters is available through SNMP access. The Web interface provides access to system configuration and performance parameters. In-band and out-of-band management options are available.

12.1 In-band and Out-of-band Managemen t

The Horizon Compact contains a dual NIC which has two 10/100/1000 Base-t Ethernet ports. These are labelled Port 1 and Port 2. The system may be configured to use EITHER Port 1 (in-band), OR Port 2 (out-of-band) for management traffic. Management traffic includes:

1. Telnet traffic and associated CLI commands

2. SNMP management

3. ping

4. FTP, used for configuration backup and restore and software upgrades.

All management functions that are available on Port 1 are also available on Port 2. Both ports may be configured to operate with or without management VLANs (see Section 11.2).

The key points to consider when choosing the network management configuration are as follows:

• Port 1 is always used for customer data traffic. It is not possible to send customer data traffic over Port 2.

• Port 1 can be configured to support management traffic in addition to customer data traffic. Use the CLI command set network management interface port1 then press Enter. The default configuration is for management data traffic to be carried over Port 1. Both ends of the link can be managed when Port 1 is set as the management interface.

• Port 2 can only be used for management. Port 2 does not carry any customer data traffic. Port 2 is disabled by default and can be enabled by using the CLI command set network management interface port2.

12.1.1 Management through Port 1 (in-band)

Port 1 is always used to carry customer data traffic and operates at rates of up to 400 Mbps over the radio link, from the local Horizon Compact system through to the far end Horizon Compact system.

Management is set to Port 1 (in-band) by default and management using Telnet, SNMP and Web interface are supported. To enable in-band management on a system that has been set to out-of-band management (Port 2), use the CLI command set network management interface port1 then press Enter.

When the network management interface is set to "port1" all management traffic must arrive on Port 1, or it will be ignored by the syste m. Configuration and management of the Horizon Compact system can be accomplished through a Telnet, or SSH, session, and although the Telnet session is intermixed with user traffic, the Telnet session occupies very little bandwidth (in the order of kbps) and therefore has almost no effect on user traffic throughput.

A Telnet, or SSH, session can be established through one Horizon Compact system, over the radio link to the far end Horizon Compact system, allowing management of both ends of the link.

Management of the Horizon Compact system can also be performed through a VLAN using 802.1Q VLAN tagging. Management through VLAN offer s increased access security. Refer to Section 11.2 for more information.

Horizon Compact Release 1. 01.01 Wireless Ethernet Product User Manual – Volume 1

Page 69

Horizon Management

12.1.2 Management through Port 2 (out-of-band)

Port 2 is available for out-of-band management purposes only. It does not carry customer data traffic. It has been designed to be used in conjunction with a management overlay network that is separate from the customer data network. Th e management overlay network is typically extended back to the Network Operations Center.

To select out -of-band management use the CLI command set network management interface port2 and press Enter. This allows management of the near end unit only. To gain access to the far end unit use the CLI command set network management interface port2 extended and press Enter. Note: With this “extended” command, an Ethernet connection must NOT be present on Port 2 of the far end system otherwise a network loop will be created.

Port 2 supports management of the Horizon Compact system through Telnet sessions , SNMP and the Web interface. When the management interface has been set to "port2", all management traffic must arrive on Port 2, otherwise it is ignored by the system. Customer data traffic continues to be carried over Port 1.

12.2 Telnet Access

Once correctly configured, the Horizon Compact is accessible through a Telnet session using Super User, NOC and Admin level user accounts. Refer to Appendix A for details of CLI commands. The Horizon Compact system can be completely configured, tested and managed through a Telnet session. The Telnet function is enabled by default but can be disabled within the Horizon Compact system. Use the CLI command set telnet [on/off] to enable or disable Telnet access.

12.3 Secure Shell Access Security

Telnet sessions over a network, such as the Internet, are not secure. User names and passwords, as well as commands and system responses, are transmitted in clear text during a Telnet session. A secure shell (SSH) protocol can be enabled in the Horizon Compact system to ensure that access to the units is restricted to authorized clients. Horizon Compact uses the Secure Shell SSH2 server programme to create the secure environment for Telnet ses sions. SSH2 is a recognised industry standard, encrypting, security programme. When enabled, SSH encrypts the entire Telnet session, including all usernames, passwords, commands and responses from the system. SSH also verifies that you are talking to the desired server by means of an authentication process using a “fingerprint”. The “fingerprint” is a unique identifier found only on the desired server.

Enable/disable SSH by issuing the CLI command set ssh server [on/off] then press Enter. The server “fingerprint” can be returned by issuing the CLI command get ssh server fingerprint then

press Enter. A Secure Shell client programme needs to be installed on any computer which is to be used to manage a

Horizon Compact system with SSH enabled. A free SSH client programme (PuTTY) is available on the Web.

Note that both SSH and Telnet can be enabled at the same time. To ensure security, once SSH has been enabled, disable Telnet.

12.4 Supported SNMP Versions

DragonWave Horizon Compact systems support three versions of SNMP.

• Version 1 (SNMP v1) is the initial implementation of SNMP.

• Version 2 (SNMPv2c) is the second release of SNMP, which has additions and enhancements to

data types, counter size and protocol operations.

• Version 3 (SNMPv3) is the most recent version of SNMP. The functionality of SNMPv1 and SNMPv2c remain intact, but SNMPv3 has significant enhancements to administration and security.

12.6 Horizon Compact SSL Web Server

The Horizon Compact Web server can be configured for Secure Sockets Layer (SSL). The Web server may be configured to operate in standard mode or in SSL mode. The Horizon Compact SSL Web server is HTTP 1.0/1.1 compliant, features full support of HTML 2.0, 3.2, 4.0 and supports SSL 3.0.

Secure Sockets Layer, SSL, is the standard security technology for creating an encrypted link between a Web server and a browser. This link ensures that all data passed between the Web server and browser remain private and integral. In order to be able to generate an SSL link, a Web server requires an SSL Certificate.

In order to invoke SSL on the Horizon Compact W eb server, an SSL certificate must be generated on the Horizon Compact. Horizon Compact uses an embedded SSL Web server from Allegro Software Development Corporation. Once generated, the certificate may be held as a private certificate or it may be registered with a Trusted Certificate Authority such as:

• Allegro Software Development Corporation

• Microsoft Root Authority

• Thawte Server

• GTE Cybertrust Root

• VeriSign RSA Secure Server

SSL access can be enabled on a per -user group basis. SSL access can be invoked for the Super User, for all NOC accounts, for all Admin accounts, or any combination of the three. Once SSL access has been enabled for the user group then all members of that user group must use SSL to connect to the Horizon Compact Web browser. Even if SSL access is not required for the user group, those users may access the Horizon Compact Web browser through HTTPS (SSL) as a security measure.

12.6.1 Generating a Certificate on Horizon Compact

In order to generate an SSL certificate on Horizon Compact, the user must be logged in as either a NOC or Super User access level. The SSL certificate is tied to the Horizon Compact IP address. If the Horizon Compact IP address is changed, then the SSL certificate should be regenerated. Otherwise the browser SSL session will allow access but it will report that the certificate is invalid. In this situation, it is the browser user's responsibility to verif y that the proper Horizon Compact is being accessed and that the invalid certificate is due to an IP address change.

12.7 Event and Performance Logs

The Horizon Compact system supports two logs, the Events Log and the Performance Log. Each can be used to trace the behaviour of the system over time.

The Events Log is invoked or disabled by issuing the CLI command set logging [on/off]. This log records alarm and reset events. Approximately 17,500 events can be captured by the Events log. Once the log is full the o ldest entries are overwritten. Use the CLI command get log entries and press Enter, to display log entries. Use Ctrl C to abort the listing.

Issuing the CLI command set performance logging [on/off] enables or disables the Performance Log. This log collects system performance information at time intervals that are configured using the CLI command set performance log interval [hh:mm:ss].

Use the CLI command get performance log and press Enter, to display a list of Performance Log entries. Use Ctrl C to abort the listing.

Between 6000 and 8000 entries can be logged before the Performance Log memory is full. Once the memory is full, new entries will overwrite the oldest entries. The following table assumes that an average of 7000 entries will occur before memory overflow. If the memory accepts more entries, then the log duration before overflow will be extended.

Logging Interval Log Duration

15 secs (minimum) ~ 29 hours 1 minute ~ 116 hours (~ 4.8 days) 15 minutes (default) ~ 73 days (~ 2.4 months) 1 hour ~ 292 days (~ 9.7 months) 24 hours (maximum) 7000 days (~ 19.2 years)

12.8 Radio Loopback

Horizon provides a radio loopback facility for analysis of transmit or receive path issues. Invoking a radio loopback is service affecting and will stop all data t ransfer. There are two options:

• Straight radio loopback - Ethernet traffic is not looped back to the network, Ethernet traffic is discarded and the RF portion of the Horizon unit is placed in loopback (see Figure 12-2).

• Radio loopback plus network loopback – Ethernet traffic and the radio are placed in loopback

During the loopback, if the modem transmitter loss of sync alarm is not active, then both the transmitter and receiver of the Horizon unit under test are functioning correctly. A user configurable time limit can be applied to the loopback feature (default is 30 seconds) . Once the time limit has expired the loopback will be automatically removed. Note that the far end transmitter should be muted when analysing the near end system using the radio loopback feature. The radio loopback is invoked or disabled by issuing the CLI command set radio loopback [on/off] [time][network].

14.0 Software Upgrades

From time to time new software loads are made available that may add new features to the Horizon Compact system. You can download new software remotely using File Transfer Protocol (FTP).

Use the Command Line Interface (CLI) via Telnet and invoke the FTP with either a local FTP server that is on the same network as the Horizon Compact system, or use DragonWave’s FTP server site available through the Internet. The Horizon Compact can interact with the most popular FTP servers on a variety of operating systems. Anonymous FTP, as well as a user –supplied username and password are supported.

14.1 Single System

Log into the system via Telnet and use the CLI command copy ftp: <filename> and press Enter. Where <filename> is the name of the software load file in the format omni_x.y.z.hex and includes any path

information. You will be prompted for the IP address of the FTP server. The FTP server will then prompt you for user

name and password. Once the download is complete you will need to use the CLI command save mib and press Enter.

The new software is now saved in non volatile memory, but not yet in use. Note that traffic is not affected during the software download process. To make the new software load active requires the system to be reset. This is traffic affecting .

To activate the new software load use the CLI command reset system and press Enter. Then press Y. The system will reset and load the new software.
