This chapter describes the Catalyst 5000 series switches. For detailed descriptions of system features and components, see Chapter 2, "Switch Description."
The Catalyst 5000 series consists of four modular LAN switches:
All switches share the same set of line cards and software features--providing scalability while maintaining interoperability across all platforms.
All switches accept Ethernet, Fast Ethernet, Gigabit Ethernet, Copper Distributed Data Interface (CDDI), Fiber Distributed Data Interface (FDDI), and ATM modules. All switches, except the Catalyst 5002, accept the Route Switch Module (RSM) and the RSM/Versatile Interface Processor 2 (VIP2). The Catalyst 5500 switch accepts LightStream 1010 ATM modules.
The Catalyst 5505 and 5500 accept redundant supervisor engines.
All switches can use Category 5 unshielded twisted-pair (UTP) cabling and multimode and single-mode fiber-optic cable.
Typically, Catalyst 5000 series Ethernet interfaces connect workstations and repeaters while the Fast Ethernet interfaces connect to workstations, servers, switches, and routers. The Gigabit Ethernet switching module provides a high-performance gigabit switching backbone while the Supervisor Engine III Gigabit Ethernet interfaces serve as uplinks that aggregate traffic from high-density 10/100-Mbps wiring closets.
Table 1-1 lists and describes the Catalyst 5000 series switches.

The Catalyst 5002 switch chassis has two slots (see Figure 1-1). Slot 1 is for the supervisor engine module, which provides switching, local and remote management, and dual uplink interfaces. Slot 2 is available for interface modules (see Table 1-1 for a list of interface modules).
The Catalyst 5002 has a 1.2-Gbps media-independent switching fabric that provides the connections between power supplies, the supervisor engine module, and the interface module. This switching fabric supports wire-speed switching for the supported line modules.
The Catalyst 5000 chassis has five slots (see Figure 1-2). Slot 1 is for the supervisor engine module, which provides switching, local and remote management, and dual uplink interfaces. Slots 2 through 5 are available for interface modules (see Table 1-1 for a list of interface modules).
The Catalyst 5000 has a 1.2-Gbps media-independent switching fabric that provides the connections between power supplies, the supervisor engine module, and the interface modules. This switching fabric supports wire-speed switching for the supported line modules.
The Catalyst 5505 chassis has five slots (see Figure 1-3). Slot 1 is for the supervisor engine module, which provides switching, local and remote management, and dual uplink interfaces. Slot 2 can contain an additional redundant supervisor engine in case the first module fails. A failure of the active supervisor engine is detected by the standby module, which then takes control of the supervisor engine switching functions. If a redundant supervisor engine is not required, slots 2 through 5 are available for interface modules.
The Catalyst 5505 is an enhanced version of the Catalyst 5000 with a three-bus 3.6-Gbps media-independent switching fabric that provides the connections between power supplies, the supervisor engine module, and the interface modules. The 3.6-Gbps media-independent fabric supports Ethernet, Fast Ethernet, Gigabit Ethernet, FDDI/CDDI, ATM LAN Emulation, ATM dual PHY DS3, RSM, and RSM/VIP2 modules. See Table 1-1 for additional information.
The Catalyst 5500 switch chassis has 13 slots (see Figure 1-4). Slot 1 is for the supervisor engine, which provides switching, local and remote management, and dual uplink interfaces. Slot 2 can contain an additional redundant supervisor engine in case the first module fails. A failure of the active supervisor engine is detected by the standby module, which takes control of supervisor engine switching functions. If a redundant supervisor engine is not required, slot 2 is available for any interface module.
The remaining slots are available for any combination of interface modules.
The Catalyst 5500 accepts LightStream 1010 ATM modules in slots 9 through 13. Slot 13 is a dedicated slot, which accepts only the ATM switch processor (ASP) module.
The Catalyst 5500 has a 3.6-Gbps media-independent switch fabric and a 5-Gbps cell-switch fabric. The backplane provides the connection between power supplies, supervisor engine, interface modules, and backbone module. The 3.6-Gbps media-independent fabric supports Ethernet, Fast Ethernet, Gigabit Ethernet, FDDI/CDDI, ATM LAN Emulation, ATM dual PHY DS3, RSM, and RSM/VIP2 modules. The 5-Gbps cell-based fabric supports an ASP module and ATM port adapters. See Table 1-1 for additional information.
