• You must carry electronic modules by only their covered edges or handles. Do not touch their
electronic components.
• Whenever a module is outside a grounded chassis, place it flat on an antistatic surface or in an
antistatic bag. Never lean the module on anything nor place anything else on top of the module nor
lean anything on the module.
• Verify that the chassis is grounded.
• Verify that you have the following tools and equipment:
• Number 1 Phillips torque screwdriver
Manual torque screwdrivers are recommended. Be sure to never exceed the
recommended torque setting for the screw that you are working with.
Note
• Replacement or new I/O module
You can replace an I/O module with another I/O module while the switch is operational. To do this action,
you must first remove an I/O module from the chassis, and then install a new or replacement I/O module in
the newly vacated slot within a couple of minutes to maintain the designed airflow.
Note
Step 1
Open a slot in the chassis for the new I/O module as follows:
If you need to remove a blank filler plate from the slot, unscrew the captive screws on either side of the module
and pull the handle on the plate to remove it from the slot. Continue with Step 2.
Note
a) Disconnect all of the networking cables attached to the front of the I/O module to be removed.
b) Unscrew the captive screw on each side of the module until the screws are loose and no longer connected to the
chassis (see Callout 1 in the following figure).
