Cisco AS5850 Universal Gateway Hardware Installation Guide

Chapter 1 Cisco AS5850 Product Overview
Field-Replaceable Units
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 field-replaceable units (FRUs).
Table 1-3 describes available Cisco AS5850 FRUs that can be ordered as spares.
For information about the feature cards used in the Cisco AS5850, refer to the Cisco AS5850 Universal
Gateway Card Guide that shipped with your system. For information about other FRUs, review the rest
of this chapter, or for detailed specification tables, refer to Appendix A, “Cisco AS5850 Specifications.”
