WS-C3750G-24TS-E1U Cisco Catalyst 3750G 24-Port Gigabit Switch, 1 RU

Rack height sets the WS-C3750G-24TS-E1U apart: it is a 1 RU stackable multilayer unit, where the WS-C3750G-24TS-E occupies 1.5 RU. It runs the IP Services software feature set (IPS), which provides full IPv6 dynamic routing, and offers 24 Ethernet 10/100/1000 ports with 4 SFP-based Gigabit Ethernet ports. No port supplies PoE.

The matching 3750G-24TS-1U entries are 4.4 x 44.5 x 37.8 cm with 128 MB of DRAM and 32 MB of flash. Its power supply maximum is 100 W, with 94 W measured at full throughput and 82 W at 5 percent throughput. AC input is 100 to 240 V at 1.5 to 3.0 A, and the RPS input is +12 V at 10.5 A.

Throughput is 38.7 Mpps for 64-byte packets. Tables are configurable to 12,000 MAC addresses, 11,000 unicast routes and 1,000 IGMP groups. Acoustic noise is 42 dB and MTBF is 221,150 hours.

Stack members share a 32 Gbps StackWise bus, with up to nine 3750 or 3750-E switches per stack. SFP modules for 1000BASE-T, SX, LX/LH, ZX and CWDM fit the uplink slots, and a Cisco RPS 2300 (PWR-RPS2300) or RPS 675 (PWR675-AC-RPS-N1=) attaches at the back. The 48-port WS-C3750G-48TS-S Gigabit switch and the rest of the 3750G family are in Cisco switches.
