Bridge LEDs

This topic describes the LEDs on bridges

Cisco Aironet 1300 Series and 1400 Series Bridge LEDs Overview

BR1310/1410 ODU has

4 LEDs LEDs have 3 major modes of operation

• Bootloader mode

• Installation mode

• Normal operation mode

Radio Status Ethernet

Install

When you power up the access point or bridge for the first time, it starts in a special installation mode The LEDs indicate the startup status, operating mode, association status, and received signal strength This information simplifies the process of activating the link and positioning the antenna from the access point/bridge mounting location

The LEDs indicate the following:

R - The radio LED blinks green to indicate radio traffic activity The light is normally off, but it blinks green whenever a packet is received or transmitted over the bridge radio link This LED also provides signal strength readings during installation mode

S - The status LED signals bridge association status Blinking green indicates that the bridge is not associated with another bridge Steady green indicates that the bridge is associated with at least one other bridge This LED also provides signal strength readings during installation mode

E - The Ethernet LED signals Ethernet traffic This LED blinks green when a packet is received or transmitted over the Ethernet infrastructure The LED is off when the Ethernet link not working or the port is shutdown This LED also provides signal strength readings during installation mode

I - The install LED indicates that installation mode is activated During installation mode, the other LEDs provide signal strength readings used for antenna alignment

LEDs have major mode operations that include the following:

Installation - The install LED indicates that installation mode is activated During

installation mode, the other LEDs provide signal strength readings used for antenna alignment

Trang 27

Bootloader - When power is applied to the bridge, the bridge activates the bootloader mode and begins the POST operation The bridge begins to load the IOS image when the Post operations are successfully completed

Normal - The bridge is performing normally as indicated by Normal Mode LED

Indications

Trang 28

Cisco Aironet 1300 Series and 1400 Series Wireless Bridges - Installing Root

Install LED

• Remains off during boot - RSSI LEDs blink to indicate POST

• Blinks amber for 60 sec

– Bridge operating as a non-root while scanning for a root

– Only for out-of-box procedure

• Turns green and starts blinking green

– Indicate the bridge has become root

– Not yet associated to non-root bridge

• Turns solid amber during installation of the root

– Bridge has located another bridge operating as Root

– Power down the interfering bridge or pre-configure this link

To configuring the root bridge complete the following:

Step 1 Mount the bridge on the site, and carefully align the bridge to the non-root side

Step 2 Power up the bridge, and observe the LEDs The Install LED of the root bridge

remains off during power up Received Signal Strength Indicator (RSSI) LEDs blink

to show that the power-on self-test (POST) is running The Install LED blinks amber for 60 seconds, meaning that the bridge is operating as a non-root while it is

scanning for a root

If a root link is not found, the Install LED blinks green, showing that the bridge has become a root but is not yet associated to a non-root bridge

Step 3 If the Install LED turns continuous solid amber during installation of the root, there

could be interference, or the bridge could be located near another bridge operating as

a root If this occurs, power down the interfering bridge or pre-configure this link

Trang 29

Cisco Aironet 1300 Series and 1400 Series Wireless Bridges - Installing Non-root

Install LED

• Remains black during boot - RSSI LEDs blink to indicate POST

• Blinks amber for 60 sec

–Bridge operating as a non-root while scanning for a root

–Only for out-of-box procedure

• Turns solid amber to indicate root association

• Install LED continues to blink amber your alignment is not sufficient

To configuring the non-root bridge complete the following:

Step 1 Mount the bridge on the site, and carefully align the bridge to the root side

Step 2 Power up the bridge, and observe the bridge LEDs

The Install LED on the root bridge remains off during the boot The RSSI LEDs blink to show POST The Install LED then blinks amber for up to 60 seconds, meaning that the bridge is operating as a non-root while it scans for a root The Install LED turns solid amber meaning root association

Step 3 If the Install LED continues to blink amber, your alignment is not sufficient You

have 60 seconds to convert the Install LED to solid amber by panning the antenna from side to side and up to down

After the Install LED turns solid amber, the RSSI LEDs show the current signal strength

Step 4 Align the antenna by panning the antenna from side to side and up to down (while

observing the RSSI LEDs) or using a DC voltmeter connected to the RSSI BNC connector Set the voltmeter to a low 5-15 volt DC scale

If a valid radio link exists, the bridges now pass traffic After you are done installing the

bridges and verifying connectivity, you can set up security, SSID, and other parameters

Radio Status Ethernet RSSI (dBm)

You can position the integrated antenna or a directional external antenna using the LEDs only after the bridge successfully associates with the remote bridge In installation mode, the Install LED is continuous amber or green when the bridge has successfully associated For the first 20 seconds following association, the bridge reads the RSSI levels from the received packets and records the maximum value After 20 seconds, the Ethernet, status, and radio LEDs on the bridge indicate relative RSSI readings compared to the maximum recorded during the initial 20 seconds

Note For the signal level (dBm), a smaller number represents a stronger signal because the

signal level is given as a negative value

Your goal is to turn as many LEDs as possible a solid amber color The remaining LEDs should blink as rapidly as possible Observe the LEDs on the bridge or use a voltmeter

measuring RSSI to align the antenna The voltmeter must be attached to the integrated BNC connector on the outdoor unit The figure shows bridge LED status

When showing the signal strength, the LEDs are amber

RSSI Reading (volts)

Nominal Signal Level (dBm)

Cisco Aironet 1400 Series Wireless Bridge Antenna Alignment

Using RSSI voltage:

• The RSSI port is a female BNC connector on bridge housing that outputs a DC voltage that

is proportional to received signal level.

• The RSSI voltage is available whenever a signal is present and the bridge is associated.

• RSSI voltage is used for aligning the root bridge in a point-to-multipoint network.

There is no RSSI voltage port on BR1310

The RSSI port produces 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

The voltage varies from 0 to 2.7 volts for signals between –90 and –20 dBm, respectively The accuracy over temperature and component variations is ± 4 dB To obtain RSSI readings, you can use any convenient voltmeter connected to the RSSI port using a cable with a male BNC connector

The following table shows the RSSI values based on the voltage read from the RSSI port
