Chapter 1 SIP and SPA Product Overview
SIP and SPA Compatibility
Shared Port Adapters
General characteristics of a SPA include:
•
•
A SPA is a modular type of port adapter that inserts into a subslot of a compatible SIP carrier card to provide network connectivity and increased interface port density. A SIP can hold one or more
SPAs, depending on the SIP type and the SPA size.
SPAs are available in the following sizes:
– Half-height—Inserts into one SIP subslot.
– Full-height—Inserts into two horizontally aligned SIP subslots. The Cisco 10000 SIP-600 supports two full-height SPAs, specified as SPA 0 and SPA 1.
– Full-height, double-wide—Occupies four standard, half-height SIP subslots.
Figure 1-1 shows the slot orientation for the SPAs.

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).
To maintain cooling integrity, either a blank filler plate (SPA-BLANK=) or a functional SPA must reside in each subslot of a SIP during normal operation. Blank filler plates are available in half-height form only.
SPAs support online insertion and removal (OIR). They can be inserted or removed independently from the SIP. The SIP also supports OIR with SPAs inserted in their subslots.
