About FiberLinX TX/FX

FiberLinX TX/FX™

from IMC Networks is a SNMP-manageable networking device for provisioning point-to-point fiber optic connections between two locations. The primary advantage of FiberLinX TX/FX is End-to-End management, which allows the device administrator to monitor the fiber run between the head-end and remote site as a single entity, not as two separate locations. FiberLinX allows the device administrator to manage the remote unit without having access to the remote site, allowing the administrator to remain isolated and completely transparent to the customer network and data traffic.

A FiberLinX TX/FX Module

Installation Instructions

Installing a FiberLinX TX/FX Module involves the following steps: 1) configuring the FiberLinX TX/FX Module via its eight-position DIP switches for SNMP-Management and mode configuraiton, 2) designation of the management traffic port, 3) configuration of host/remote or standalone operation and auto-negotiation; along with the installation of the FiberLinX

TX/FX module into a PowerChassis/101 or /113 (not for use with PowerChassis/1, /2 or /12).

➤ DIP SWITCH SETTINGS

Before installing FiberLinX TX/FX into a PowerChassis, you must configure the eight-position DIP switch, located at positions S1 and S3 (shown on the following page), for configuring the module.

DIP Switch Location on FiberLinX TX/FX (default settings shown)

The following table shows the function for each of the eight DIP switches on FiberLinX TX/FX. Refer to the following pages for specific configuration information for each function.

➤ CONFIGURING FIBERLINX TX/FX AS A HOST,

EMOTE OR STANDALONE UNIT

When two FiberLinX TX/FX units are paired with one another, each FiberLinX TX/FX unit can be configured to be either a

Host

unit or a

Remote

unit.

As a Host, FiberLinX TX/FX requests management information from any attached remote unit and displays that information, along with its own, upon SNMP query. As a Remote, FiberLinX TX/FX will not respond to requests for management information from an attached unit. In single installation, the sole FiberLinX TX/FX should be configured as standalone unit (factory default). The table on the following page shows the possible DIP switch settings. Please see page 10 of this guide for possible installations and their related Host, Remote and standalone DIP switch settings.

➤ SNMP MANAGEMENT

TRAFFIC

Although FiberLinX TX/FX provides a twisted pair port solely for manage- ment traffic, you can configure FiberLinX TX/FX to accept SNMP management traffic from any of its three ports. There are four different ways you can configure FiberLinX TX/FX to accept (or not accept) SNMP management traffic. Only one source for SNMP management traffic can be active at any time, and only the SNMP management traffic directed to the module’s IP address will be accepted.

FiberLinX TX/FX is configured at the factory to accept SNMP management traffic from the twisted pair data port, with DIP switch

2 on switch S3 ON,

DIP switch

1 and 3 OFF). You can change this setting by adjusting DIP

switches 1 though 3.

About FiberAlert

FiberAlert is an advanced troubleshooting feature that can help you locate "silent failures" on your network. However, it is vital that you understand exactly how FiberAlert works, and how it will react in your network configuration, before attempting to install the enclosed module.

Installing modules without understanding the effects of FiberAlert can cause perfectly functional units to appear flawed or even dead!

FiberAlert lets you know when a fault occurs on your fiber loop by stopping data transmissions and affecting the fiber LEDs on both sides of your network. Since FiberLinX TX/FX is a transparent link in a network, the FiberAlert feature, a troubleshooting feature that assists in pinpointing link faults between products, is implemented. If FiberLinx TX/FX is not receiving

Installation Instructions

Once the DIP switches are set, you are ready to install FiberLinX TX/FX,

which can be installed into any PowerChassis/100 or /113 chassis.

To install FiberLinX TX/FX, remove the blank bracket covering the slot, if necessary, where you will be installing the module, then slide the module into the chassis, via the cardguides, until the module is seated securely in the connector. Secure the module to the chassis by tightening the captive screws. Once the module is installed, you will need to assign an IP address to the unit, which can be done via HUBCTRL32™ (Hub Control

32) or serial configuration.

Assigning IP Information

In order for FiberLinX TX/FX to allow for SNMP-management, the module must be assigned IP configuration information (e.g., IP address, subnet mask, etc.). There are two ways to do this:

• Using HUBCTRL32 over an Ethernet connection

• Using the unit’s serial port

Besides assigning an IP address and subnet mask, the two methods will also allow you to create community strings, assign access rights, configure traps and more. However, HUBCTRL32 offers more options than the serial port method (e.g., you can select which traps to assign with HUBCTRL32). Note that if you are using HUBCTRL32, you must have the SNMP/HUBCTRL32 Function enabled via DIP switch (see Figure 2 on page 2 for details).

Once FiberLinX TX/FX is assigned an IP address, you can use iView or another SNMP-compatible Network Management System (NMS) to remotely configure, monitor and manage the media conversion modules installed in the unit (see page 8 of this guide for more information).

NOTE

FiberAlert should only be activated on one side of a media extender. Activating the feature on both sides would keep both transmitters off indefinitely.

Page 3

➤ ABOUT HUBCTRL32

HUBCTRL32 is an in-band configuration utility created by IMC Networks that lets users quickly and easily complete the first stages of SNMP configuration for IMC Networks SNMP-manageable devices.

Tasks HUBCTRL32 can perform include:

• setting the IP address, subnet mask and default gateway

• defining the community strings and SNMP traps

In addition to the above functions, HUBCTRL32 offers an authorized IP address system and access restriction to MIB groups supported by IMC Networks manageable devices. These extra layers of security are purely optional and do not affect SNMP compatibility in any way.

HUBCTRL32 can also be used to upload new versions of the system software and new MIB information. It also offers diagnostic capabilities for faster resolution of technical support issues.

HUBCTRL32 works with the following platforms:

• Windows 98™ • Windows NT™ • Windows 2000™

HUBCTRL32 can be found on the iView CD, or you can download it from the IMC Networks Web site (

www.imcnetworks.com/tech/software

). For information regarding the use of HUBCTRL32, refer to the HUBCTRL32 online help file.

CP/IP Information

To modify the Saved Parameter Values (i.e., assign IP address and subnet mask), press I. You will be instructed to enter the IP address and subnet mask for the connected device. Press Enter after each. You may also assign a default gateway, if desired (press Enter to skip).

When finished, press Enter, then type “Reboot” for changes to take effect. The Saved Values and Current Values should now both display the changes made (e.g., new IP address and subnet mask).

NOTE

Because a Delete key is not available on VT-100 terminal emulators, use the F2 key instead.

NOTE

You must reboot after making any modifications to the Saved Values or your changes will not take effect. To reboot, type the word “Reboot” (no quote marks) at the prompt on the main configuration screen, or turn the chassis power OFF then ON again.

Page 4

Creating Community Strings

The default community string is named “public” and has read/write access. IMC Networks recommends you set up two communities: one with read-only access (for general use), the other with read/write access (for the administrator). To create a new community string, go to the main configuration screen and press C. Enter the name of the new community (up to 16 characters, no spaces) and press Enter. Then type one of the following to assign the community string’s access rights:

• R = read-only access • W = read/write access • Enter = abort

Press Enter.

When finished, press Enter, then type “Reboot” for changes to take effect. The Saved Values and Current Values should now both display the changes made (e.g., new IP address and subnet mask).

Deleting Community Strings

To delete all community strings and start over, press U. You will then be asked, “Are you sure you want to delete all future strings?” Press Y to proceed, N to abort. Press Enter.

Note that the above function will delete ALL community strings. If you want to be able to selectively delete community strings, use HUBCTRL32 to configure your device.

Assigning T

rap Destinations

Traps are sent by the manageable device to a management PC when a certain event takes place.

To enter a trap destination, press T. You will then be asked to “Enter a New IP Address.” Type the IP address of the destination device and press Enter. Then type the name of the community string (created earlier) and press Enter.

Note that the above function enables ALL of the traps the device is capable of. If you want to be able to selectively activate and de-activate traps, use HUBCTRL32 to configure your device.

Removing Trap Destinations

To remove all trap destinations, press K. You will then be asked if you really want to remove all trap destinations. Press Y to continue. Press N to abort. Press Enter.

Password Protection

You can password protect the serial configuration process by pressing P from the main configuration screen. You will be asked to enter a password. (NOTE: Passwords are case sensitive.) Enter your password (spaces are NOT allowed) and press Enter. You will then be asked for your password whenever you log on or off. To remove password protection, select P and instead of entering a password, press Enter.

Should you forget the password, use HUBCTRL32 to access the back-up copy of the PROM, then reburn the flash PROM (or contact IMC Networks technical support for assistance).

Ending Your Session

Be sure to press E before disconnecting the cable in order to stop the device from outputting to the serial port.

USING IVIEW

If you will be using another application for management, you will need to integrate the IMC Networks SNMP vendor files (a.k.a. MIBs) into your application. Consult the documentation of your SNMP-manageable NMS for details. FLINX.MIB must be integrated into the management software to successfully manage FiberLinX TX/FX.

How FiberLinX TX/FX Works

The movement of data from one port to another is accomplished via packet forwarding. The destination address of each Ethernet packet entering the FiberLinX TX/FX is checked to determine whether it is a management packet or a downstream data packet, and is forwarded appropriately. Packets not addressed for management ports are sent through to the network. Similarly, management packets are forwarded internally to the management engine and are not forwarded.

In this situation, configure the Central site’s unit as a Host with management traffic through the twisted pair data port, and the Remote site's unit to accept management traffic through the fiber data port.

Note that the twisted pair management ports on both FiberLinX TX/FX remain unused.

Configure the two FiberLinX TX/FX units used in this example exactly as the ones in Example 2, except direct management traffic on the Central site’s unit to the twisted pair management port.

Example 3

DIRECT FIBER SWITCH CONNECTION FROM C ENTRAL

REMOTE SITE

To achieve remote management and monitoring capabilities, directly connect a FiberLinX TX/FX to a fiber-based switch. All SNMP management traffic and data traffic goes straight into the switch at the Central site via the fiber port. SNMP management traffic is imbedded within the corporate network, but no management data passes to the Remote site.

Configure FiberLinX TX/FX to accept SNMP management traffic from the fiber port. In this application, FiberLinX TX/FX is neither a Host nor Remote unit. The twisted pair management port on this FiberLinX TX/FX is unused.

Troubleshooting

➤ If FiberLinX TX/FX is connected to a non-negotiating device, sometimes

the Duplex mode will not auto-negotiate. This can be fixed by changing the settings in iView.

FIBER OPTIC CLEANING G UIDELINES

Fiber Optic transmitters and receivers are extremely susceptible to contamination by particles of dirt or dust which can obstruct the optic path and cause performance degradation. Good system performance requires clean optics and connector ferrules.

1) Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable supplier; low quality components can cause many hard-to-diagnose problems in an installation.

2) Dust caps are are installed at IMC Networks to ensure factory-clean optical devices. These protective caps should not be removed until the moment of connecting the fiber cable to the device. Assure that the fiber is properly terminated, polished and free of any dust or dirt and that the location is as free from dust and dirt as possible.

3) Store spare caps in a dust-free environment such as a sealed plastic bag or box so that when reinstalled they do not introduce any contamination to the optics.

4) Should it be necessary to disconnect the fiber device, reinstall the protective dust caps.

5) If you suspect that the optics have been contaminated, alternate between blasting with clean, dry compressed air and flushing with methanol to remove particles of dirt.

LECTROSTATIC DISCHARGE P RECAUTIONS

Electrostatic discharge (ESD) can cause damage to your add-in modules. Always observe the following precautions when installing or handling an add-in module or any board assembly.

1) Do not remove unit from its protective packaging until you’re ready to install it.

2) Wear an ESD wrist grounding strap before handling any module or component. If you do not have a wrist strap, maintain grounded contact with the system unit throughout any procedure requiring ESD protection.

WARNING! Integrated circuits and fiber optic components are extremely susceptible to electrostatic discharge damage. Do not handle these components directly unless you are a qualified service technician and use tools and techniques that conform to accepted industry practices.

3) Hold boards by the edges only; do not touch the electronic components or gold connectors.

Page 8

4) After removal, always place the boards on a grounded, static free surface, ESD pad or in a proper ESD bag. Do not slide the board over any surface.
