In the Cisco switches range, the WS-C4948E-F-S pairs 48 10/100/1000 RJ-45 ports with four SFP or SFP+ uplinks and one management port. Its IOS feature set is IP Base, which covers static routing, RIPv1 and RIPv2, and EIGRP stub.
Cooling is back to front through hot-swap fans that move 28 CFM at low speed and 44 CFM at maximum. The AC input range is 90-264 VAC; typical consumption is 230 W at 25 degrees C and maximum consumption is 275 W at 55 degrees C. The height is 1RU.
Across the 4948E-F family, the switch fabric is non-blocking at 176 Gbps, hardware forwarding reaches 131 Mpps for IPv4 and 110 Mpps for IPv6, and each unit has 1 GB SDRAM, a 1 GHz CPU, room for 57,000 routes and 55,000 MAC addresses. The minimum release is 12.2(54)WO, and images exist in standard and 3DES K9 builds. Power is 1+1 redundant and hot-swappable. Weight is 8.62 kg (19 lb) fully loaded, or 6.35 kg (14 lb) without power supplies and fan tray.
