Hardware Problems
The following sections describe problems you may encounter with switch hardware.
LEDs Do Not Light on All Modules
You have turned on the power supply to the switch, but the LEDs on the modules do not
light.
Probable Cause
The power supply has blown a fuse.
Solution
Call Alcatel Technical Support.
Amber Color in LEDs
During power-up, the switch goes through a Power-On Self Test (POST). Results of the test
are reflected in the OK1 and OK2 LEDs on the MPX and switching modules; specifically, OK1
indicates hardware failures, while OK2 indicates software failures.
The first time you start the switch, the
OK1 LED will blink in amber once to indicate start
mode. The OK2 LED will blink in green rapidly to indicate image loading. Thereafter, OK2
should blink slower in green to indicate operational mode.
Probable Cause
Hardware failure or software failure.
Solution
If the amber LED displays on a switching module, replace the module with a known, good
module.
If the amber
LED displays on the MPX, or after replacing the switching module the problem
persists, shut down the switch and call Alcatel Technical Support.
Non-Blinking OK2 LED
When the switch is operating properly, the OK2 LED blinks in green. When the OK2 LED
displays a steady green light, this is an indication of problems.
Probable Cause
The MPX or the software is malfunctioning. Typically the problem cannot be resolved by
rebooting.
Solution
Shut down the switch and call Alcatel Technical Support.
