This Catalyst 4900M half card adds 20 wire-speed 10/100/1000 RJ-45 copper ports to the 8-port WS-C4900M base system. The base unit takes two half cards in any combination, and this one occupies a single half-card slot.
The card is marked wire-speed, so all 20 ports can forward at line rate together. Cards can be inserted and removed while the switch is running. Two of these cards give the chassis 40 copper Gigabit ports, which is the maximum 10/100/1000 count for the platform. The chassis it plugs into is rated at 320 Gbps and 250 mpps, with a 1:1 uplink-to-downlink ratio and wire-speed uplinks across any half-card pairing.
The card measures 1.9 x 7.4 x 8.2 in (49 x 188 x 209 mm) and weighs 1.5 lb (0.7 kg). The switch needs IOS Software 12.2(46)SG or later to run the platform. The card can be ordered as the spare WS-X4920-GB-RJ45= or inside a fully configured system.
