Cisco AS5850 Chassis

The Cisco AS5850 contains 14 slots (numbered 0 through 13 on the backplane) and can support trunk cards and universal port cards in slots 0 through 5 or 8 through 13. Slots 6 and 7 in the chassis are dedicated slots for the RSCs. There are two versions of the RSC, RSC and ERSC. ERSC has a faster CPU, more memory, and two Fast Ethernet ports. Metal guard pins on the backplane module prevent you from installing any other type of card in these two slots. The modular chassis supports online insertion and removal (OIR) and redundant power and includes environmental monitoring and feedback control.
