Troubleshooting The Fabric Modules - Cisco Nexus 7000 Series Troubleshooting Manual

Troubleshooting the Fabric Modules

a) Loosen the captive screws on the module so that they are no longer in contact with the chassis.
b) 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.
d) Push the module back into the chassis until it is seated on the midplane.
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
Troubleshooting a DC Power Supply Unit, on page
Step 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.

Troubleshooting the Fabric Modules
The following conditions indicate problems with one or more fabric modules:
• The FAB LED on the chassis is amber.
• The STATUS LED on the fabric module is red.
Note
When you start up the switch or install a new fabric module, the STATUS LED on the module is amber while
the module initializes. When the module becomes operational, the STATUS LED becomes green. If an
overtemperature condition occurs, the STATUS LED flashes red.
For a listing of the fabric module LEDs and the conditions that they indicate, see
To troubleshoot a fabric module hardware problem, follow these steps until the problem is resolved:
SUMMARY STEPS
1. Check if a STATUS LED is flashing red or is unlit on each fabric module.
2. Check if the power supply units are providing power to the chassis components.
3. Make sure that the fabric module is properly seated in the chassis as follows:
