SPA Slot Numbering on the Cisco CRS-1 SIP-800
The Cisco CRS-1 SIP-800 accepts six single-height SPAs. Figure 2-4 shows a Cisco CRS-1 SIP-800
with two 4-Port OC-3c/STM-1 POS SPAs installed in subslots 0 and 3.
Note Subslots 0, 1, and 3 can provide up to 20 Gbps of capacity, as can subslots 2, 4, and 5. Take care not to
install SPAs that require more than 20 Gbps of capacity in each group of subslots so as not to
oversubscribe the card. See the “Bandwidth Oversubscription” section on page 3-2 for more
information.
Figure 2-4 and Figure 2-5 illustrate the SPA subslot locations on the Cisco CRS-1 SIP-800. The subslot
labels are located inside the SPA subslot and are only visible when the SPA is not installed.
