Step 5
Verify that the power supply unit is functional by replacing it with another power supply and plugging its power cords
into the same power source.
If you cannot determine the problem with the power supply or determine which power supply unit has the problem,
contact TAC.
Troubleshooting the Supervisor Modules
The following conditions indicate a problem with one or more supervisor modules:
• The SUP LED on the chassis is amber.
• The STATUS LED on a supervisor module is amber, red, or not lit.
• The CMP STATUS LED on a supervisor 1 module is amber or red.
• An ACT LED on a supervisor module is not lit.
The SYSTEM and PWR MGMT LEDs on the supervisor modules indicate that there could be problems with
the supervisor module or any of the other switch modules.
When you start up the switch, the supervisor module STATUS and CMP STATUS LEDs are amber while
the module runs diagnostic tests. When the module passes the diagnostic tests and becomes operational, the
STATUS and CMP STATUS LEDs become green. For switches that have two supervisor modules, the
ACTIVE LED is green for the active supervisor module or amber for the standby supervisor module. When
the SYSTEM and PWR MGMT LEDs are green, the switch does not detect any critical system problems.
Amber, red, or unlit LEDs indicate system problems that you need to resolve, possibly with other system
modules.
For a listing of supervisor module LEDs and the conditions that they indicate, see
To troubleshoot for a hardware problem with the supervisor module, follow these steps until the problem is
resolved:
SUMMARY STEPS
1. Check if the STATUS LED (all supervisors modules) or CMP STATUS LED (Supervisor 1 modules
only) is amber, red, or unlit on each supervisor module as follows:
2. If the STATUS LED (all supervisors modules) and CMP STATUS LED (Supervisor 1 modules only) are
unlit, check the module seating and power connections as follows:
3. If the LOG FLASH or EXPANSION FLASH (Supervisor 1) or SLOT0 (Supervisor 2 or 2E) LED is not
lit, a compact flash slot (Supervisor 1) or USB port (Supervisor 2 or Supervisor 2E) is empty. If you need
to load storage media in the slot or port, make sure that the media is formatted correctly for the slot.
4. Contact TAC for assistance (see the
