The Catalyst 4503-E switch supports the Supervisor Engine II+, Supervisor Engine II+TS, Supervisor
Engine II+10GE, Supervisor Engine IV, Supervisor Engine V, Supervisor Engine V-10GE, and
Supervisor Engine 6-E. The supervisor engine has a nonblocking, full-duplex, switching fabric that
provides connections between the supervisor engine and the switching modules. Some supervisor
engines use SFP modules for Gigabit Ethernet connections, or X2 modules for 10-Gigabit Ethernet
connections. Refer to the installation note for your supervisor engine for more details on these modules.
Slot 1 is reserved for the supervisor engine only, which provides switching, local and remote
management, and switch-status monitoring. Slots 2 and 3 are available for switching modules. The
chassis will support up to 24 Gbps per slot for slots 2 and 3, for a maximum of 116 ports with a
Supervisor Engine II+TS, or 96 ports and 2 uplinks for other supervisors.
