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
