Cisco CRS-1 Carrier Routing System SIP and SPA Hardware Installation Guide

Chapter 1 SIP and SPA Product Overview
SIP and SPA Compatibility
• Either a blank filler plate (SPA-BLANK=) or a functional SPA should reside in every subslot of a
SIP during normal operation to maintain cooling integrity. Blank filler plates are available in
single-height form only.
• SPAs support online insertion and removal (OIR). They can be inserted or removed independently
from the SIP. SIPs also support OIR.
SIP and SPA Compatibility
Table 1-1 shows the SIP that is supported in the Cisco CRS-1 router and the SPAs that it supports.
Note For more information about the introduction of support for different SIPs and SPAs, refer to
Cisco IOS XR Interface and Hardware Component Configuration Guide.
Modular Optics Compatibility
Some SPAs implement small form-factor pluggable (SFP or XFP
1
) optical transceivers to provide
network connectivity. An SFP module is a fiber-optic transceiver device that mounts in the front panel
to provide network connectivity.
Cisco Systems qualifies the SFP modules that can be used with SPAs.

equal to or greater than 10
Gbps.
