WS-C3750X-24S-S Cisco Catalyst 3750-X 24-Port SFP Switch

This is a stackable 1 RU Catalyst 3750-X switch with 24 Gigabit Ethernet SFP ports and the IP Base feature set, shipped with a 350 W AC power supply that carries no PoE budget. IP Base adds baseline Layer 3 routing, including routed access with OSPF, MACsec and Embedded Event Manager, on top of the LAN Base set; full EIGRP, BGP, PIM and advanced IPv6 routing need the IP Services upgrade.

A uplink network module slot accepts optional modules; none ship by default and they can be hot-swapped. The choices are a 4-port Gigabit Ethernet module, a 10 Gigabit module with two SFP+ and two SFP ports, a 2-port 10GBASE-T module, and a Service Module with two 10 Gigabit SFP+ ports. The power supply bays are modular and redundant: a single supply sits in bay 1, a 440 W DC supply is an optional spare, and AC and DC units can be mixed. Switching fabric capacity is 160 Gbps, forwarding is 65.5 Mpps measured with two 10 Gigabit uplinks, and jumbo frames up to 9216 bytes are supported.

Up to nine switches can form one StackWise Plus stack with 64 Gbps of stack throughput, managed as one unit; a full 3750-X stack reaches 432 Gigabit Ethernet ports. This SFP-port model has 512 MB of DRAM and 128 MB of flash, the larger of the two memory configurations in the family. It measures 1.75 x 17.5 x 18.0 in (4.5 x 44.5 x 46.0 cm), weighs 15.4 lb (7.0 kg), and draws about 108 W at idle in a standalone configuration with a 1G uplink module and no PoE load. Uplink modules for the slot include the 4-port 1G SFP network module and the 10G network module.
