The WS-C3750G-12S-SD is the DC-powered 3750G with 12 SFP-based Gigabit Ethernet ports and no fixed copper ports. Its input is -36 to -72 VDC at 3.0 to 1.5 A, for sites with DC feeds instead of mains. The software is the IP Base feature set (IPB), a 1 RU stackable multilayer unit.
This DC model weighs 4.1 kg with, a power supply maximum of 72 W and an MTBF of 259,729 hours. Measured draw is 72 W at full throughput (245 BTU per hour) and 61 W at 5 percent throughput (207 BTU per hour).
IP Base covers quality of service, rate limiting, access control lists, static routing, RIP and EIGRP stub routing. Each of the 12 slots takes an SFP module for 1000BASE-SX, LX/LH, ZX, 1000BASE-T or CWDM. The 32 Gbps StackWise bus joins up to nine 3750 and 3750-E units into one stack with a single IP address.
Mains-fed 12-port models also exist in the 3750G family, including the WS-C3750G-12S-S SFP switch and the WS-C3750G-12S-E SFP switch, and both are in the Cisco switches range.
