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 on which you can place the removed interface processor, and an
antistatic container in which you can place a failed port adapter for shipment back to the factory.
The PA-T3 serial port adapter can be installed on a VIP2-15, VIP2-20, or VIP2-40
Note
motherboard; however, installation on the VIP2-10 is not recommended.
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.
Each port adapter circuit board is mounted to a metal carrier and is sensitive to ESD damage.
Note
The following procedures should be performed by a Cisco-certified service provider only. The VIP2
supports online insertion and removal (OIR), but individual port adapters do not. To replace port
adapters, you must first remove the VIP2 from the chassis and 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 and then remove the blank port adapter.
