Cisco PA-T3 Installation And Configuration Manual page 31

When only one port adapter is installed on a Catalyst RSM/VIP2, you must use a blank port adapter
to fill the empty slot. This allows the Catalyst RSM/VIP2 and the Catalyst RSM/VIP2 chassis to
conform to electromagnetic interference (EMI) emissions requirements and encourages air to flow
through the chassis properly. If you plan to install a new port adapter, you must first remove the blank
port adapter.
Removing a Port Adapter
Following is the standard procedure for removing any type of port adapter on the
Catalyst RSM/VIP2:
Step 1
Step 2
Step 3
Step 4
Figure 4-2
Step 5
Step 6
Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
Note If you want to install a new port adapter on a Catalyst RSM/VIP2 with a single port
adapter, you must first remove the blank port adapter from the port adapter slot in which
you want to install the new port adapter.
For a new port adapter installation or a port adapter replacement, disconnect any interface
cables from the ports on the front of the port adapter, although this is not required. You
can remove the Catalyst RSM/VIP2 with cables attached; however, we do not recommend
it.
To remove the Catalyst RSM/VIP2 from the chassis, follow the steps in the Route Switch
Module Catalyst VIP2-15 and VIP2-40 Installation and Configuration Note (Document
Number 78-4780-01) which shipped with your Catalyst RSM/VIP2. Place the removed
Catalyst RSM/VIP2 on an antistatic mat.
Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced.
(See Figure 4-2.) This screw secures the port adapter (or blank port adapter) to its slot.

Remove the screw that secures the port adapter (or blank port adapter).
With the screw removed, grasp the handle on the front of the port adapter (or blank port
adapter) and carefully pull it out of its slot, away from the edge connector at the rear of
the slot. (See Figure 4-3.)
