Cisco ASR 1000 Series Software Configuration Guide

Fully populate all slots and subslots with blank filler plates or functional SPAs for maximum efficiency
of the cooling system.
Note
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 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.
•
Some SPAs provide services rather than network connectivity, and can be inserted into the subslots of
a compatible SIP, for example, the Cisco WebEx Node for ASR 1000 Series that provides WebEx
meeting services, and the DSP SPA that provides voice transcoding and transrating capabilities.
•
SPAs are available in the following sizes, as shown in the following figures:
◦ Single-height SPA—Inserts into one SIP subslot.
◦ Double-height SPA—Inserts into two single, vertically aligned SIP subslots.
