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.

Note The PA-T3 serial port adapter can be installed on a VIP2-15, VIP2-20, or VIP2-40

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.

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. 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.
