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 0through 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.
Table 1 -1 shows the possible trunk card configurations for RSC:
Table 1 -2 shows the possible trunk card configurations for ERSC:
