WS-C4500X-24X-ES is one of the Catalyst 4500-X Series Switches. The Catalyst 4500-X series switch is a 1RU unit that provides either 16 or 32 10GBASE-X (SFP+) or 1GBASE-X (SFP) ports. An additional 8 ports of 1000BASE-X (SFP) or 10GBASE-X (SFP+) are available in a removable Ethernet uplink module that mounts in a bay on the front of the switch chassis.
