Description

The Catalyst 3750-X WS-C3750X-24U-S is a 1RU stackable enterprise access switch for campus and branch networks that need high-power PoE. It suits converged wired and wireless deployments powering UPOE and PoE+ devices such as IP phones, Aironet access points, VDI clients, IP turrets and personal TelePresence endpoints.

It provides 24 10/100/1000 Ethernet ports with Cisco Universal PoE, delivering up to 60W per port. The default C3KX-PWR-1100WAC power supply provides 800W of available PoE power, and the maximum UPOE budget is 1800W per switch with two 1100W AC supplies. The switching fabric is 160 Gbps with a 65.5 Mpps forwarding rate, and StackWise Plus gives 64 Gbps of stack bandwidth. This SKU runs the IP Base feature set, which adds routed access (RIP, EIGRP stub, OSPF for routed access), StackPower and MACsec. IP Services can be reached through a software activation upgrade.

A network module slot accepts the hot-swappable uplink modules C3KX-NM-1G, C3KX-NM-10G, C3KX-NM-10GT and C3KX-SM-10G. It stacks with other Catalyst 3750-X and 3750-E switches using StackWise Plus cables.

FAQs

Q: Which feature set does the WS-C3750X-24U-S run?
A: It runs the IP Base feature set. IP Base adds routed access, StackPower, MACsec and Service Module support. A software activation upgrade to IP Services is available.

Q: How much PoE power does it provide?
A: With the default 1100W AC power supply it provides 800W of available PoE power. Adding a second 1100W AC supply raises the maximum UPOE budget to 1800W.

Q: Which uplink modules fit the network module slot?
A: The slot accepts C3KX-NM-1G (4 x GbE SFP), C3KX-NM-10G (2 x 10GbE SFP+ with 2 SFP), C3KX-NM-10GT (2 x 10GBASE-T) and the C3KX-SM-10G Service Module.

Q: Can it be stacked with other switches?
A: Yes. StackWise Plus stacks up to nine Catalyst 3750-X or 3750-E switches with 64 Gbps of stack bandwidth, using CAB-STACK cables. StackPower cables (CAB-SPWR) let the stack share power.

Q: What is the difference between UPOE and PoE+?
A: PoE+ supplies up to 30W per port, while UPOE supplies up to 60W per port. UPOE suits higher-power endpoints such as VDI clients and personal TelePresence units.
