Catalyst 4003 Switch (Front View)
The Catalyst 4003 switch has a Gigabit Ethernet port and a 12-Gbps nonblocking,
full-duplex switching fabric that provides connections between the supervisor
engine and the switching modules. The Catalyst 4003 switch supports the
Supervisor Engine I. The Supervisor Engine I has a 10BASE-T Ethernet
management port (RJ-45 connector) and a console port (DCE DB-25 connector).
The Catalyst 4003 chassis has three slots for online-swappable modules. Slot 1 is
reserved for the supervisor engine, which provides switching, local and remote
management, and switch-status monitoring. Slots 2 and 3 are available for
switching modules.
