Cisco 12000 SIP-601 Overview
SPA Subslot Numbering on the Cisco 12000 SIP-601
The Cisco 12000 SIP-601 accepts 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.
Figure 1-19 shows a Cisco 12000 SIP-601 with 2 SPAs installed. The left SPA slot is subslot 0 and the
right SPA slot is subslot 1. If one dual-width SPA is installed, it is recognized as being in subslot 0.

SPA Interface Addresses on the Cisco 12000 SIP-601
A Cisco 12000 Series Router identifies a SPA interface address by its SIP slot number, SPA subslot, and
port number on the SPA, in the format slot/subslot/port. Subslots and ports are numbered starting from
0, so each Cisco 12000 SIP-601 has two subslots 0 (left) and 1 (right). For example, the interface address
of a 1-port SPA located in the second SIP subslot, where the SIP is inserted into router line card slot 3
is 3/1/0. Figure 1-20 shows the slot, subslot, and port locations for the 1-Port 10-Gigabit Ethernet SPA
and the 10-Port Gigabit Ethernet SPA.
