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).

Two handles spring out part way from the front of
the module
3Loosen the two captive screws1
Press the two ejector buttons2
c) Press the two ejector buttons on the each side of the module (see Callout 2 in the above figure).
The two handles spring out part way from the front of the module.
d) Fully rotate the two handles away from the front of the module and pull on them to move the module part way out
of its slot.
e) Place one hand under the module to support its weight, grasp the front of the module with the other hand, pull the
module fully out of its slot, and set the module on an antistatic surface.
Do not touch any electrical circuitry on the removed I/O module. Handle the module only by its covered
surfaces (front and bottom of the module) and always set the module on an antistatic surface when it is not
inside the chassis.
Caution
Step 2 Install the new I/O module in the open slot as follows:
a) Unpack the new I/O module, set it right side up on an antistatic surface (so that you can see the electrical components
from above the module), and inspect the module for damage.
If anything is damaged, contact your customer representative immediately.
