Cisco Catalyst 3548 switch- 48 ports 2 x GB Ports

The Catalyst 3500 series XL switches are workgroup Ethernet switches that supply Gigabit Ethernet and autosensing 10BaseT or 100BaseTX connections in individual switches and in clustered configurations. These switches---also referred to as 3500 XL switches---can be deployed as backbone switches aggregating 10/100 and Gigabit Ethernet traffic from other switches and hubs or in mixed configurations connecting hubs, switches, servers, and desktop computers or servers.
