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
page D-2.
To troubleshoot for a hardware problem with the supervisor module, follow these steps until the problem
is resolved:
Check if the STATUS or CMP STATUS LED is amber, red, or unlit on each supervisor module as
Step 1
follows:
If either the STATUS or CMP STATUS LED is amber or flashing red, a minor (amber) or critical

(flashing red) overtemperature condition exists. Contact TAC for assistance (see the
Customer Service" section on page
• If the STATUS LED is red, the initialization process detected a parity error condition. Contact TAC
for assistance (see the
Step 2 If the STATUS and CMP STATUS LEDs are unlit, check the module seating and power connections as
follows:
a. Loosen the captive screws on the module so that they are no longer in contact with the chassis.
Unseat the module by pressing the ejector buttons on each end of the module and swinging out each

ejector lever.
c. Place one hand on the handle for the module and pull the module part way out of the chassis.
Push the module back into the chassis until it is seated on the midplane.
d.
e. Rotate both ejector levers until they both touch the front of the module. Make sure that each captive
screw on the fan tray is aligned with its hole in the chassis.
f. Securely tighten each captive screw (to 8 in-lb [0.9 N·m]) to the chassis.
g. Verify that the Output LED on each power supply is lit. If the Output LED is not lit, troubleshoot
the AC power supply units (see the

If the PCMCIA LED is not lit, the compact flash slot is empty. If you need to load a compact flash card
