WS-C3750G-24PS-E Cisco Catalyst 3750G 24-Port PoE Gigabit Switch

The WS-C3750G-24PS-E carries the IP Services software feature set (IPS), the PoE counterpart of the 3750G family with full IPv6 dynamic routing. Its 24 Ethernet 10/100/1000 ports support IEEE 802.3af and Cisco prestandard PoE, and 4 SFP-based Gigabit Ethernet ports sit beside them in a 1 RU stackable multilayer chassis. IPS brings hardware-based IPv6 and multicast routing that the IP Base image on the WS-C3750G-24PS-S does not include.

Each of the 24 powered ports can supply 15.4 W together, which covers Cisco IP phones, Cisco Aironet access points and other IEEE 802.3af devices. For the 3750G-24PS the power supply maximum is 540 W and the AC input is 100 to 240 V at 4.0 to 8.0 A, 50 to 60 Hz. The rear RPS connector takes a Cisco RPS 2300 (PWR-RPS2300) or RPS 675 (PWR675-AC-RPS-N1=), drawing +12 V at 14 A.

The 3750G-24PS forwards 38.7 Mpps of 64-byte packets and has 128 MB of DRAM and 32 MB of flash. Table sizes reach 12,000 MAC addresses, 11,000 unicast routes and 1,000 IGMP groups. The case measures 4.4 x 44.5 x 37.8 cm and weighs 6.1 kg. Acoustic noise runs from 38 to 44 dB as PoE load grows, and MTBF is 182,373 hours.

The 32 Gbps StackWise bus joins up to nine 3750 or 3750-E units in one stack, and the SFP slots accept 1000BASE-T, SX, LX/LH, ZX and CWDM modules. Other 3750G models, such as the non-IPS WS-C3750G-24PS-S PoE switch, are in Cisco switches.
