Removing a Port Adapter
When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot. This
allows the VIP2 and router 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.

Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
If you want to install a new port adapter on a VIP2 with a single port adapter, you
Note
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 VIP2s with cables attached; however, we do not recommend it.
To remove the VIP2 from the chassis, follow the steps in the section "Removing a VIP2"
in the configuration note Second-Generation Versatile Interface Processor (VIP2)
Installation and Configuration, which shipped with your VIP2. Place the removed VIP2
on an antistatic mat.
Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced.
(See Figure 3-3.) 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 3-4.)
