The Catalyst 4503 switch supports the Supervisor Engine II, II+, II+TS, II+10GE,
IV, V, V-10GE and 6-E. The supervisor engine has a nonblocking, full-duplex,
switching fabric that provides connections between the supervisor engine and the
switching modules. The Gigabit Ethernet ports can be configured with any
combination of copper 1000BASE-T, shortwave SX, LX/LH, and ZX interfaces,
or CWDM and DWDM GBICs. For a description of GBICs, refer to the Catalyst
4500 Series Module Installation Guide or the Catalyst 4500 Series Supervisor

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.
