The WS-C3750-48PS-S is a Catalyst 3750 stackable multilayer switch in a 1 RU chassis. It carries 48 Ethernet 10/100 ports with IEEE 802.3af and Cisco prestandard Power over Ethernet, plus 4 SFP-based Gigabit Ethernet ports, and it runs the IP Base (IPB) software feature set.
The switch has a 32-Gbps switching fabric and a forwarding rate of 13.1 mpps. Memory is 128 MB of DRAM and 16 MB of flash. Cisco StackWise creates a 32-Gbps interconnection between switches, and up to 9 units can be stacked.
For power planning, the 3750-48PS has a 540 W supply with a 370 W PoE load at 100 percent throughput. In the 48-port PoE versions, 24 ports can run at 15.4 W or all 48 ports at 7.7 W. AC input is 100 to 240 VAC at 4.0 to 8.0 A, 50 to 60 Hz, and the redundant power input is +12 V at 7.5 A.
The chassis measures 1.73 x 17.5 x 14.8 in (4.4 x 44.5 x 37.8 cm) and weighs 13.2 lb (6.0 kg).
