Description

The Catalyst 3750-X is a stackable 1 RU access layer switch for enterprise campus and branch networks that need high-density Universal PoE. This model provides 48 10/100/1000 UPOE-capable ports, each able to deliver up to 60W, which suits IP phones, wireless access points, VDI clients, IP turrets and personal TelePresence endpoints.

It ships with the LAN Base feature set and a default 1100W AC power supply (C3KX-PWR-1100WAC) that provides 800W of PoE power. The switching fabric is 160 Gbps with a forwarding rate of 101.2 mpps when fitted with two 10GbE uplinks. No uplink module is fitted by default. Optional hot-swappable modules add 4x 1G SFP (C3KX-NM-1G), 2x 10G SFP+ (C3KX-NM-10G) or 2x 10GBASE-T (C3KX-NM-10GT) connectivity, and the C3KX-SM-10G Service Module is also supported.

StackWise Plus provides 64 Gbps of stack throughput for up to nine switches managed as a single unit, while StackPower shares power across up to four stacked switches. A LAN Base switch can only stack with other 3750-X LAN Base switches. A full 1800W UPOE budget needs two 1100W AC power supplies.

FAQs

Q: Which licence does this switch run?
A: It ships with the LAN Base feature set, which provides Layer 2 features, up to 255 VLANs and static routing with 16 routes. It can be upgraded through Cisco IOS software activation to IP Base or IP Services.

Q: Does it include an uplink module?
A: No uplink module is fitted by default. Optional hot-swappable modules are the C3KX-NM-1G (4x 1G SFP), C3KX-NM-10G (2x 10G SFP+ or 4x SFP) and C3KX-NM-10GT (2x 10GBASE-T). The C3KX-SM-10G Service Module is also supported.

Q: How much PoE can it deliver?
A: With the default 1100W AC supply it provides 800W of PoE power. Delivering 60W UPOE or 30W PoE+ on all ports needs two 1100W AC supplies, which gives the full 1800W budget.

Q: Can it stack with other 3750-X switches?
A: Yes, using StackWise Plus for up to nine switches. A LAN Base switch can only stack with other 3750-X LAN Base switches, as mixed stacking with IP Base or IP Services is not supported.

Q: Which power supplies does it support?
A: It supports dual redundant modular supplies: C3KX-PWR-350WAC, C3KX-PWR-715WAC, C3KX-PWR-1100WAC and C3KX-PWR-440WDC. The XPS 2200 expandable power system is also compatible.
