Replace Fabric Module
Step 2
Position the fan tray with its rear (the side with the electrical connectors) at the opening for the fan tray slot
in the chassis.
Step 3
Align the two tracks on the top of the fan tray with the two sets of rails at the top of the open fan tray slot in
the chassis.
Step 4
Slide the fan tray all the way into the slot until the front of the fan tray touches the chassis.
Make sure that the four captive screws on the front of the fan tray align with the four screw holes in the chassis.
Step 5
Screw in the four captive screws to secure the fan tray to the chassis. Tighten the screws to 8 in-lb (0.9 N·m)
of torque.
Step 6
Verify that the fan tray STATUS LED turns on and becomes green, approximately within 20 seconds.
Replace Fabric Module
The switch supports replacement of a fabric module while others are operating. To replace a fabric module,
you must do each of the following:
• Shut down the fabric module being replaced.
• Remove the fan tray covering the fabric module in the chassis.
• Remove the fabric module.
• Install the new fabric module.
Note
• Reinstall the fan tray over the fabric module.
• Activate the fabric module.
The Cisco 9800 series switches support OIR of fabric module.
To maintain the designed airflow while you remove the fan tray, the fans in the other fan trays increase their
speed. During operations, it is required that you remove only one fan tray at a time and reinstall that fan tray
within three minutes to avoid the possibility of having the switch overheat and shut down. If you remove more
than one fan tray at a time, the switch shuts down if you do not reinstall the extra missing fan trays within
two minutes (the shutdown can occur earlier if the switch over heats).
