Replacing a module
Before you replace a module, remove all its cables. To remove the cables from a service module, you
can first remove the cable management brackets at the two sides of it.
The replacement procedure is similar for MPUs, service modules, and fabric modules. Before you
rotate outward the ejector levers of the module, perform either of the following tasks:
•
MPU or service module
—Loosen the captive screws on the module.
•
Fabric
module
—Press the buttons on the ejector levers to release them.
If you are not to install a module in a slot, install a blank filler panel in the slot to ensure adequate
ventilation and dust prevention.
