Chapter 1 MSCs and SPA Product Overview

MSC and SPA Compatibility

Shared Port Adapters

The following list describes some of the general characteristics of a SPA:

• A SPA is a modular type of port adapter that inserts into a subslot of a compatible MSC carrier card

to provide network connectivity and increased interface port density.

Figure 1-1 SPA Sizes for the Cisco 7304 Router

•

Each SPA provides a certain number of connectors, or ports, that are the interfaces to one or more

networks. These interfaces can be individually configured using the Cisco IOS command-line

interface (CLI).

• Either a SPA blank filler plate or a functional SPA should reside in every subslot of an MSC during

normal operation.

• SPAs support online insertion and removal (OIR). They can be inserted or removed independently

from the MSC. MSCs also support online insertion and removal (OIR) with SPAs inserted in their

subslots.
