Guide to Supported Hardware for Cisco 7600 Series Routers with Cisco IOS Release 12.2SR
OL-10362-06
Supported Hardware
OC-12 ATM
Note Also has four Layer 2 LAN ports.
SPA Interface Processors (SIPs)Note See the Release Notes for Cisco IOS Release 12.2SR on the Cisco 7600 Series Routers for information
about additional procedures required to support SIPs with Cisco IOS Release 12.2(33)SRA and later
releases.
SIP-400 Combinations
The SIP-400 linecard supports an aggregate forwarding rate of approximately 6 Mpps. Packet
forwarding is done by microcode on the network processors so enabling datapath features may reduce
performance.
For release 12.2(33)SRA, the total supported bandwidth for the SIP-400 is 4 Gigabits line rate for
Ethernet and 2.5 Gigabits line rate for SONET with selected services. There is no oversubscription
support. The product ordering tools would prevent combination of SPAs that add up to more than this
bandwidth and would reject such configurations.
For release 12.2(33)SRB and above, the following SPA combinations are supported on SIP-400:
