Maintaining the Cisco Catalyst 5500 Multiswitch Router

This chapter contains recommended hardware maintenance procedures for the Cisco Catalyst 5500 Multiswitch Routers (MSRs), which provide an Ethernet backbone for connections between the Cisco Signaling Link Terminals (SLTs), Cisco Media Gateway Controllers (MGCs), and Cisco Media Gateways (MGWs). You can configure several virtual LANs (VLANs) on the Catalyst 5500s and the route switch modules (RSMs) provide inter-VLAN routing when necessary. If your solution includes two Catalyst 5500s, they are connected through an Inter-Switch Link (ISL) trunk, enabling them to share VLAN data and provide ensured availability.

This chapter describes hardware maintenance; for information on upgrading and maintaining Catalyst 5500 software, refer to the Cisco Media Gateway Controller Software Release 7 Installation and Configuration Guide.

This chapter includes the following sections:
