Removing a Fabric Module
Note
The fabric modules must be installed in specific slots as follows (installing fabric modules in other slots can
cause a module mismatch condition):
• For three modules, they must be in slots FM 2, FM 4, and FM 6.
• For four modules, they must be in slots FM2, FM 3, FM 4, and FM 6.
• For five modules, they must be in Slots FM 2, FM 3, FM 4, FM 5, and FM 6.
• For six modules, they are in slots FM 1, FM 2, FM 3, FM 4, FM 5, and FM 6
You can replace a fabric module while other fabric modules are operating by removing the fan tray in front
of the fabric module. Remove the fabric module, then install the new fabric module, and replace the fan tray
over the installed 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, we recommend that you remove only one fan tray at a time and reinstall that fan
tray within three minutes. This action avoids the possibility of having the switch overheat and shut down.
Caution
Removing a Fabric Module
Before you begin
• Wear an electrostatic discharge (ESD) wrist strap or other ESD protective device while handling modules.
• Prepare an antistatic surface or packing materials for each module that you remove from the chassis.
• Remove the fan tray that covers the fabric module that you are removing.
Step 1
If you are replacing a fabric module, open the packaging for the new module and inspect it for damage.
If the module is damaged, alert the Technical Assistance Center (TAC) and stop this replacement process until you have
an undamaged module to install.
Step 2
Remove the fan tray that covers the fabric module by following these steps:
a) Unscrew the two captive screws on the front of the fan tray until each screw is free of the chassis. See Callout 1 in
the following figure.

If you are downgrading the operating system, you must ensure both of the following:
• The new version of software supports the fabric modules and line cards, which are installed in the
same switch.
• The fabric modules that are installed in the switch, support the line cards that are installed in the
same switch.
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.
