Chapter 1 Cisco AS5850 Product Overview
In systems with two RSCs, the way the RSC uses the backplane buses will depend on the mode the system is operating in. Sometimes one RSC will control all the backplane DS0s and sometimes their use will be divided between the RSCs.
Environmental Monitoring
Environmental monitoring for the full chassis is carried out by both RSCs. This means that warnings about overheating cards go to both RSCs, regardless of which one owns the slot. Sending the warnings to both RSCs reduces the chance of an environmental problem going unreported.
For detailed chassis specification tables, refer to Appendix A, “Cisco AS5850 Specifications.”
Field-Replaceable Units
The Cisco AS5850 is designed to make component removal and replacement easy. This section describes the Cisco AS5850
