PA-A1 and PA-A3 VIP2

Configurations Supported

Overview

Supporting physical interfaces up to 155 Mbps, the ATM port adapter (PA-A1) and the Enhanced ATM port adapter (PA-A3) require a large

amount of switching performance and bandwidth capacity. Consequently, certain combinations of ATM port adapters and other port adapters

can exceed the capabilities of Versatile Interface Processor (VIP2) models that were designed for lower performance and bandwidth

applications. Therefore, in some conﬁgurations no other port adapter can be installed in the VIP2 when an ATM port adapter is installed.

This document summarizes the ATM port adapter/VIP2 conﬁgurations supported, and also describes the new dual port adapter support

in the same VIP2-50 with the OC-3/Synchronous Transport Module level 1 (STM-1) version of the PA-A3 in IOS Release 11.1(21)CC

(orderable as 11.1(21)R) or higher.

Configurations Supported

• A single PA-A1-OC3MM or PA-A1-OC3SM can be installed in the VIP2-15, VIP2-40, or VIP2-50 with no other port adapter in the other

slot. There are no plans to provide dual port adapter support on any VIP2 for PA-A1-OC3MM and PA-A1-OC3SM.

• The PA-A3-T3 and PA-A3-E3 are supported on the VIP2-40 and VIP2-50. All port adapter combinations are supported with the PA-A3-T3

or PA-A3-E3 in the VIP2-40 or VIP2-50, including two PA-A3-T3 or PA-A3-E3 port adapters in the same VIP2-40 or VIP2-50. There are

no plans to provide PA-A3-T3 or PA-A3-E3 support on the VIP2-15.

• The PA-A3-OC3SMM, PA-A3-OC3SMI, and PA-A3-OC3SML are supported on the VIP2-40 and VIP2-50. A single PA-A3-OC3SMM,

PA-A3-OC3SMI, or PA-A3-OC3SML can be installed in the VIP2-40 with no other port adapter in the other slot. All port adapter

combinations are supported with PA-A3-OC3SMM, PA-A3-OC3SMI, and PA-A3-OC3SML in the VIP2-50, including two

PA-A3-OC3SMM, PA-A3-OC3SMI, or PA-A3-OC3SML port adapters in the same VIP2-50. There are no plans to provide

PA-A3-OC3SMM, PA-A3-OC3SMI, or PA-A3-OC3SML support on the VIP2-15.
