All Cisco uBR10012 1-Gbps wideband half-height SPAs requires a carrier (product number UBR10-2XDS-SIP). Each carrier holds two half-height line cards; a blank (product number SPA-BLANK) is shipped with any carrier with open half-height SPA slots.
Cisco recommends that customers who order spare carrier or half-height SPAs also order enough blanks to ensure that the configurated system has no empty slots.
