14 Channelized T1 Port Adapter Installation and Configuration
VIP2 and the 2CT1 Port Adapter
Installing or Replacing a Port Adapter on a VIP2
Depending on the circumstances, you might need to install a new port adapter on a VIP2
motherboard or replace a failed port adapter in the field. In either case, you need a number 1 Phillips
screwdriver, an antistatic mat onto which you can place the removed interface processor, and an
antistatic container into which you can place a failed port adapter for shipment back to the factory.
Caution
To prevent system problems, do not remove port adapters from the VIP2 motherboard, or
attempt to install other port adapters on the VIP2 motherboard while the system is operating. To
install or replace port adapters, first remove the VIP2 from its interface processor slot.
Note
Each port adapter circuit board is mounted to a metal carrier and is sensitive to ESD damage.
The following procedures should be performed by a Cisco-certified service provider only. While the
VIP2 supports online insertion and removal (OIR), individual port adapters do not. To replace port
adapters, you must first remove the VIP2 from the chassis, then install or replace port adapters as
required. If a blank port adapter is installed on the VIP2 in which you want to install a new port
adapter, you must first remove the VIP2 from the chassis, then remove the blank port adapter.
When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot to
allow the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions
requirements, and to permit proper airflow through the chassis. If you plan to install a new port
adapter, you must first remove the blank port adapter.
Use the following procedure to remove and replace any type of port adapter on the VIP2:
Step 1
Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
Step 2
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. You can remove VIP2s with cables
attached; however, we do not recommend it.
Step 3
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.
Step 4
Place the removed VIP2 on an antistatic mat.
Step 5
Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced. (See
Figure 9.) This screw secures the port adapter (or blank port adapter) to its slot.
