The WS-C4900M is the Cisco Catalyst 4900M 8-port base system: a 320-Gbps, 250-million-packets-per-second, two-rack-unit fixed-configuration switch with eight fixed wire-speed X2 ports and two optional half-card slots. Throughput is 250 mpps for IPv4 and 125 mpps for IPv6.
The base unit accepts up to two half cards. Cisco's 4900M half cards are the WS-X4904-10GE (4-port 10GE with X2 interfaces), WS-X4908-10GE (8-port 10GE with X2 interfaces), WS-X4908-10G-RJ45 (8-port 10GBASE-T RJ-45) and WS-X4920-GB-RJ45 (20-port 10/100/1000 RJ-45). A fully loaded switch reaches 24 10 Gigabit Ethernet fiber ports, 16 10 Gigabit Ethernet RJ-45 ports or 40 10/100/1000 ports.
Power is a choice of 1000 W AC or DC supplies in a 1+1 hot-swappable arrangement, and the switch can run with one supply present. Power supplies are ordered separately. The base unit with its fan and no power supply weighs 25.0 lb (11.3 kg), and measures 3.5 x 17.2 x 17.9 in (89 x 437 x 455 mm). The 4900M runs Cisco IOS Software only, from Release 12.2(46)SG.
Half cards for the base system include the WS-X4908-10G-RJ45 8-port 10GBASE-T half card and the WS-X4920-GB-RJ45 20-port gigabit half card. More models are in Cisco switches.
