The Cisco 12000 SIP-501 supports 4 single-height SPAs (the aggregate throughput should not exceed 2
full-rate SPAs); 2 double-height SPAs; 1 dual-width, double-height SPA, or a combination of
single-height and double-height SPAs.
The interconnect between a SIP and a SPA can operate at either 2.5Gbps or 10Gbps. If the maximum
capacity of a SPA is greater than 2.5Gbps the interconnect operates at 10Gbps and the SPA is a "full-rate"
SPA. If the maximum capacity of a SPA is 2.5Gbps or less the interconnect operates at 2.5Gbps and the
SPA is a "quarter-rate" SPA. The Cisco 12000 SIP-501 can support up to two full-rate SPAs, or one
full-rate and three quarter-rate SPAs or four quarter-rate SPAs.
The Cisco 12000 SIP-501 face plate has one Status LED. Figure 1-14 shows the Cisco 12000 SIP-501
face plate with 4 single-width, single-height SPAs.
