Question about Cisco Aironet 340 Wireless Bridge
The ethernet and status indicators of my aironet 340 bridge are flashing red blinking lights while the radio led is not lighting up or showing any signs of activity. This happened after a storm passed by. I have no idea what to do. I've also tried turing on and off the bridge but its still the same. I'm suspecting that my device is broken.
Yes, unfortunately your device is busted . Power surge might have cause it. next best thing what we can think of right now is what to replace it.
Pls feel free to ask Fixya if you may have additional questions

The front panel Status LED provides an indication of
the set's operation and the possible cause of a malfunction.
If an abnormal condition is indicated, perform the
Self Diagnostics procedure.
To activate, press the front panel <ACTIVITY> &<CH
??> buttons at the same time and hold for 5 seconds.
The STATUS LED will then flash denoting a two digit
• The number of flashes indicates the value of the
MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2
• The LED then flashes indicating the value of the
(ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "23", the LED
will flash two times, pause, and then flash three

Error Codes, descriiptions and the most likely cause of
the error are listed in Table 2-3.
Note: The TV must be in "Shut Down." The LED
will probably be indicating an abnormal
condition. If the TV is switched Off, AC is
removed, or a System Reset is performed, the
code automatically resets to "12" No Error.

READING CODES Modes will not switch while the engine is running. The ECM automatically switches to MODE I when the ignition is switchedOFF.
1984-90 Vehicles With Dual LED System
The self-diagnostic system has 5 modes. To switch modes, switch the ignition ON and use a screwdriver to turn the mode select switch through the access port on the ECM. The inspection lights will begin to flash. When the desired mode has been entered, turn the screwdriver fully counterclockwise. The red LED and green LED perform different functions in different modes.
This is the normal vehicle operating mode. The green LED will indicate loop status. If the green LED is not blinking when the engine is running, the vehicle is in open loop, or the HO 2 S, O 2 S, or sensor circuit has a malfunction. If the green LED is blinking, the vehicle is in closed loop. If a malfunction takes place, the red LED and the MIL will glow, indicating a malfunction has occurred.
Both the red LED and green LED are used to monitor mixture ratio feedback control. The green LED will function as described in MODE I. If vehicle is in open loop, the red LED and green LED will remain on or off. In order for results to be valid, vehicle must be in closed loop. In closed loop, the red LED remains off if the system is running rich, comes on if the system is running lean, and blinks at the same time with the green LED if system is within 5% of the exact air/fuel ratio.
-When this mode is accessed, the codes stored in the ECM's memory will be flashed by the green LED and red LED on the side of the ECM. The red LED will light first. This is the first digit of the trouble code; the green LED will flash next, showing the second digit of the code. For example: 2 flashes of the red LED followed by 1 flash of the green LED corresponds to Code 21.
This mode is used for checking the throttle plate (TP) switch, starter, and vehicle speed switch status. When the TP switch or starter switch is activated, the red LED will briefly flash as the status changes. For VSS status, the green LED will remain off when vehicle speed is less than 12 mph (19 km/h) and come on when vehicle speed is greater than 12 mph (19 km/h).
This mode represents a real-time diagnostic test of the crank angle sensor, ignition signal and the mass airflow signal. The malfunction code will be displayed only when the malfunction occurs and will not be stored in memory. The output code will appear as a single or short string of pulses. Count the number of pulses for the malfunction code.
1 pulse-CMP sensor signal lost or noise in signal 2 pulses-MAF Sensor signal abnormal 3 pulses-Fuel pump circuit shorted or open 4 pulses-Ignition signal lost

The unit has LED activity indicators on the front of the case provide a status display indicating error conditions, transmission, and network activity for the 802.11a (amber) radio or the 802.11b/g (green) radio.
802.11a Activity LED Amber
The amber LED flashes three times per second until firmware is loaded. During boot, 802.11a mobiles cannot associate. After adoption, the amber LED is steady or flashes with 802.11a radio traffic.
The amber LED flashes once per second if an error prevents the 802.11a radio from operating normally.
802.11b/g Activity LED Green
The green LED flashes three times per second until firmware is loaded. During boot, 802.11b/g mobiles cannot associate. After adoption, the green LED is steady or flashes with 802.11b/g radio traffic.
The green LED flashes once per second if an error prevents the 802.11b/g radio from operating normally.
From this, it appears that the 802.11A radio is malfunctioning.
