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.
