The bridge receives inline power fr om the Cisco Aironet Power Injector LR (hereafter called the power injector). Dual-coax Ethernet cables are used to provide Ethernet data and power from the power injector

to the bridge. The p ower inje c tor is an ext erna l u ni t de sign ed fo r ope ra ti on in a sh el te red environmen t, such as inside a building. The power injector also functions as an Ethernet repeater by connecting to a Category 5 LAN bac kbone a nd usi ng the d ual -coa xial ca ble int erfac e t o the bri dge.

Chapter 1 Overview

The power injector uses an external 48 VDC power module and after detecting the presence of the bridge, injects the DC voltage into the dual coax cables to power the bridge.

Note The power injector and the power module shoul d not be plac ed in an outdoor unprotected environment.

External Antenna

The bridge is availabl e wi th a n N-t ype R F conn ec to r on t he f ron t of t he uni t ( see Figure 1-1) for an external 5.8-GHz anten na. The supp orted externa l ante nnas conne ct to the bri dge ant enna conn ector using the antenna’s 4.9 ft (1.5 m) long coax cable.

Key Features

Integrated Antenna

The bridge is availabl e w ith a n in tegrat ed 22. 5 d Bi p at ch ar ray a nt enna . T he a nte nna i s covered w ith a special radome cover to protect the antenna from environmental elements. When configured with the integrated antenna, the antenna polarization is controlled by the mounting orientation of the bridge. The bridge must be physically rotated 90 degrees to obtain either horizontal or vertical polarization. A special polarization mark is designed into the bridge housing to indicate the polarization direction.

Dual-Coax Ethernet Ports

The bridge’s dual Ethernet ports accep ts a pair of 7 5 ohm F-type conn ectors, linking the bridge to your 100BASE-T Ethernet LAN through the power injector. The dual coax cables are used to send and receive Ethernet data, pl us the cabl es supp ly in lin e 48 VD C power f rom th e power inj ect o r. For th e loc atio n of the ports, refer to Figure 1-2.

Tip You can connec t the dual coax cabl e connec tors to eit her of th e br idge ’s Ethernet po rts. Th e br idge

senses the Ethernet signals an d au to matically switches internal circuitry to match the ca ble connections.

Metal Enclosure

The bridge uses a metal en closure that suppo rts outdo or operati ng environments and suppo rts an industrial temperature operating range (refer to Bridge Speci fications, pa ge 1 -6).

• The Ethernet indicator signals Ethernet traffic. This indicator blinks green when a packet is received

or transmitted over the Ethernet infrastru ctu re. The in dicator is off when the Ether net link not working or the port is shutdown. This indicator also provides signal strength readings during installation mode.

For additional information on the LED indicators, refer to“Checking the LED Indicators” s ectio n on

page 5-2.

Receive Signal Strength Indicator Port

The bridge supports a radio signal strength indicator (RSSI) port for use in antenna alignment. The RSSI port produces a DC voltage proportional to the strength of the received radio signal. The highest voltage indicates the best antenna alignment position. The RSSI port is a male BNC connector located on the bottom of the br id ge ho using (se e Figure 1-2).

Note The RSSI port requires the use of a voltmeter and a cable with a female BNC connector.

Safety Information

DRAFT - CISCO CONFIDENTIAL

Warning

This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security.

Safety Information

Follow the guidelines in this section to ensure proper operation and safe use of the bridge.

FCC Safety Compliance Statement

The FCC, with its action in ET Doc ket 96-8, has adop ted a safe ty standard for human exposur e to RF electromagnetic energy emitted by FCC-certified equipment. When used with approved Cisco Aironet antennas, Cisco Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio device according to the instructions in this publication results in user exposure substantially below the FCC recommended limits.

Safety Precautions

Warning

Each year hundreds of people are killed or injured when attempting to install an antenna. In many of these cases, the victim was aware of the danger of electrocution, but did not take adequate steps to avoid the hazard.

For your safety, and to help you achieve a good installation, please read and follow these safety precautions. They may save your life!

1. If you are installing an antenna for the first time, for your own safety as wel l as other s, seek

professional assistance.

2. Select your installation site with safety, as well as performance in mind. Remember: electric power

lines and phone lines look alike. For your safety, assume that any overhead line can kill you.

3. Call your electric power company . Tell them your plans and ask them to come look at your proposed

installation. This is a small inconvenience considering your life is at stake.

4. Plan your installa tio n ca re fully a nd co mp let ely befo re you begin. Suc cessf ul r aisi ng of a m ast or

tower is largely a matter of coordination. Each perso n should be assign ed to a spec ific task, and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watc h for sign s o f troub le.

5. When installing your antenna, remember:

a. Do not use a metal ladder. b. Do not work on a we t or wi ndy da y.

OL-4072-01

Safety Information

DRAFT - CISCO CONFIDENTIAL

c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or

jacket.

6. If the assembly starts to drop, get away from it and let it fall. Remember, the antenna, mast, cable,

and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any of these parts to a power line complete an electrical path through the antenna and the installer: you!

7. If any part of the antenna syste m should com e in cont act wit h a power line, don ’t touch it or try to

remove it yourself. Call your local power company. They will remove it safely.

If an accident should occur with the power lines call for qualified emergency help immediately.

Installation Guidelines

Because the bridge is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these basi c guideli nes to ensure t he best possible performa nce:

• Install the bridge in an area where structures, trees, or hills do not obstruct radio signals to and from

the bridge.

• Install the bridge at a height sufficient to provide line-of-sight orientations.

Site Surveys

Because of differen ces i n comp one nt co nfigurat ion, p lac em ent , an d p hysi cal environmen t, every network application is a unique installation. Before installing multiple bridges, you should perform a site survey to determine the optimum utilization of networking components and to maximize range, coverage, and network p erfor ma nce.

Consider the following operating and environmental conditions when performing a site survey:

• Data rates—Sensitivity and range are inversely proportional to data bit rate s. The maxi mum radi o

range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases.

Installation Guidelines

• Antenna type and p lacement—Proper antenna configuration is a critical factor in maximizing radio

range. As a general rul e, ra nge in cr ease s in p rop ortio n to an te nna he ig ht. However , d o not pl a ce the antenna higher than necessary, because the extra height also increases potential interference from other unlicensed radio systems.

• Physical environment—C lear or open areas provide better radio range than closed or filled areas.

• Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of

wireless devices. Avoid loca ting the devices in a location where there is an obstruction between the sending and receiving ante nnas.

Unpacking the Bridge

Follow these steps to unpack the bridge:

Step 1 Open the shipping container and carefully remove the contents. Step 2 Return all pack i ng ma ter ials t o t he sh ippi ng conta ine r and save it. Step 3 Ensure that all items listed in the “Package Contents” section are included in the s h ipment. Check each

When the bridge is initially powered-up, installation mode is activated and the bridge attempts to associate to a root bridge for 60 seconds. If it is unable to associate with a root bridge, it automatically assumes the root bridge role. The Install LED provides bridge association status during installation mode as shown in Table 3-2.

You use the Install LED to determine when the bridge successfully associates with a remote bridge and to verify its mode of operation. A fter associat ion, the other three LEDs indicat e signal stre ngth (see

Table 3-3).

The startup and associa tion sequ ence d epends on th e bridge configuratio n, which ca n be one of the following types:

• Default—The bridge attemp ts to ass oci ate with a ro ot br idge fo r 30 sec onds . If it does not asso ci ate

with a root bridge, it then attempts to associate with a non-root bridge.

• Pre-configured—The bridge attempts to associate with a remote bridge in the configured mode,

either root or non-root. Because there are no time-outs, it is easier to align the antenna.

Aligning the Antenna Using LED Indications

You can align the integrated antenna using LEDs after the bridge successfully associates with a remote bridge. In the installation mode before association to another bridge, the Install LED blinks amber. If the bridge associates to a root bridg e, the I nstall LE D turn s stead y amber. If the bridge do es not assoc iate to a root bridge in th e first 30 seco nds, the Inst al l LE D b lin ks g reen to i ndic ate b ea cons ar e be ing transmitted and the bridge is waiting for another non-root bridge to associate. After association, the Install LED turns into steady green and the Ethernet, status, and radio LEDs then display signal strength as shown in Table 3-3).

Aligning the Antenna Using LED Indications

Note For the signal leve l (dBm), a smaller number represents a stronger signal because the signal le vel is gi ven

as a negative value.

Note Each time you move the antenna, you must wa it approximately 20 seconds before the LED patterns are

valid.

1. Slow blinking rate of 1 Hz/sec.

2. Medium blin kin g r ate of 2 Hz /se c.

3. Fast blinking rate of 4 Hz/sec.

When using LEDs to maximize the signal, you adjust the antenna until as many LEDs as possible are turned-on and t he r est ar e blinki ng as fa st a s p ossibl e.

Aligning the Antenna Using the RSSI Voltage

The RSSI port outputs a DC voltage that is proportional to the received signal level. The RSSI voltage is available whenever a signal is present, regardless of the bridge mode (installation or normal), association status, or pre-configuration role setting. The RSSI voltage provides an instantaneous reading as you move the antenna. The RSSI port is a female BNC connector on the bridge housing (see Figure 1 ).

The RSSI voltage increases linearly with signal level as shown in Table 4.

Note A larger RSSI voltage reading indicates a stronger signal.

Obtaining and Assigning an IP Address

To browse to the bridge’s Express Setup page, you must e ithe r obt ain or a ssign the bridg e’s IP address using one of the f ol lowing me thod s:

• Use default addre ss 10.0 .0 .1 whe n y ou conne ct to the br idge loc a lly. For detailed instruc ti ons, se e

the “Connecting to the Bridge Locally” section on page 4-3.

• Use a DHCP server (if available) to automatically assign an IP address. You can find out the

DHCP-assigned IP address usi ng one of the following meth ods:

–

Provide your organization’s network ad mini stra tor wi th y our br i dge’s Media Access Contro l (MAC) address. Your network administrator will query the DHCP server using the MAC address to identify the IP address. The bridge’s MAC address is on label attached to the bottom of the bridge.

–

Use the Cisco IP Setup Utility (IPSU) to identify the assigned address. You can also use IPSU to assign an IP address to the bridge if it did not receive an IP address from the DHCP server. IPSU runs on most Microsoft Windows operating systems: Windows 9x, 2000, Me, NT, and XP .

You can download IPSU from the Software Center on Cisco.co m. For additional informa tion refer to the “Obtaining and Installing IPSU” section on page 4-9.

Obtaining and Assigning an IP Address

Connecting to the Bridge Locally

If you need to configure the br idge loca lly (wit hout conn ecting th e bridge ’s power injector to a wired LAN), you can connect a PC to the power injector’s Ethernet port using a Category 5 Ethernet cable. Y ou can use a local connecti on to the Et hernet port muc h as you would use a serial port conn ecti on.

Note You do not need a specia l crosso v er cabl e to connec t your PC to th e bridge’s power injector; you

can use either a straight-t hrough ca ble or a crossover cable .

-----Can someon e verify the f ollowing D HC P Ser ver sta tem en t -----

If the bridge is c onfigured with d efa ult values and n ot co nne ct ed to a D HCP se rver or cann ot obt ai n a n IP address, it defaults to IP address 10.0.0.1 and becomes a mini-DHCP server. In that capacity, the bridge provides up to twenty? IP addresse s betw een 10. 0. 0.1 1 and 10 .0.0. 30 to an Ethern et-c apa ble PC connected to the power injector’s Ethernet port.

The mini-DHCP server feature is disabled automatically when you assign a static IP address to the bridge.

Caution When a bridge with default settin gs i s conne ct ed on a wi red LA N a nd does no t re c eive an IP add ress

from a DHCP server, the bridge provides an IP address to any DHCP requests it receives.

Follow these steps to connect to the bridge locally:

OL-4072-01

Step 1 Make sure that the PC you intend t o use is configured to obtain an IP address auto matically, or manually

assign it an IP address from 10.0. 0.31 to 10. 0.0.40 . Conne ct your PC to the power inject or using a Category 5 Ethernet cable. You can use either a crossover cable or a straight-through cable.

Step 2 Power up the power injector.

Power Injector LED Indicators

The power injector contains three LED indicators to provide status information on the wired Ethernet link, the bridge Ethern et link, an d the brid ge status. Whe n the power inject or is powered up, it send s a constant discovery tone on the du al-c oax c able s to the b ridg e. When t he bri dge is conn ec te d to the dual-coax cables, it returns the disco ve ry tone to the po wer injecto r . When the power injector detect s the returned discovery tone, it applies +48 VDC to the dual-coax cables to the bridge.

When power is applie d to the bridge, th e bridge acti vates th e bootloader and be gins the POST oper ations. The bridge begins to load the IOS ima ge when the Post operati ons are succ essfull y comple ted. Upon successfully loading the IOS image, the bridge initializes and tests the radio.

SSID

To associate, all bridges must use the same SSID. The bridge installation mode SSID is autoinstall and the normal mode default SSID is tsunami. Y ou should verify the SSID value shown on the Express Setup page is the same for all bridges. Y ou should also verify the bridges are configured for the proper network role; only one bridge can be configured as th e root bri dge.

Security Settings

Remote bridges attempting to authenticate with your bridge must support the same security options configured in the bridge, such as WE P, EAP or LEAP, MAC address au thent ication, Message Int egrity Check (MIC), WEP key hashi ng, a nd 802.1 X prot ocol vers ions.

If a remote bridge is unable to auth enticate with your bridge, veri fy the security settings a re same as your bridge settings. For additional information, refer to the Cisco Aironet 1400 Series Bridge Software Configuration Guide.

Antenna Alignment

If your bridges are unable to associate together, you should verify the basic configuration settings on all bridges before a ttem pti ng to ver ify bri dg e a nten na al ignme nt (r ef er t o “Configuring the Bridge for the

First Time” section on page 4-1). If your basic configurations settings are correct, you can verify antenna

alignment by using the the RSSI port. The RSSI port can be used even when the bridges are not associated.

Note T o meet re g ulatory res trictio ns, th e ex ternal an tenn a bridg e configuration and the external an tenn a must

be professional insta lled.

The RSSI port outputs a DC voltage that is proportional to the received signal level. The RSSI voltage is available whenever a signal is present, regardless of the bridge mode (installation or normal), association status, or pre-configuration role setting. The RSSI voltage provides an instantaneous reading as you move the antenna . T he RSSI po rt i s a fe m ale BN C conne c tor on the br i dge h ousin g. To obtain RSSI readings, you can use any convenient voltmeter connected to the RSSI port using a c able with a male BNC connector.

The RSSI voltage increases linearly with signal level as shown in Table 6.

Chapter 5 Troubleshooting

Note A larger RSSI voltage reading indicates a stronger signal.
