The WS-X4904-10GE is the Cisco Catalyst 4900M 4-port wire-speed 10 Gigabit Ethernet half card with X2 interfaces. The 4900M is a 320-Gbps, 2RU fixed-configuration switch with eight fixed X2 ports and two half-card slots, and a half card goes in either slot.
The base unit takes up to two half cards in any combination, which lets this card sit beside the 20-port 10/100/1000 RJ-45 card, the 8-port 10 Gigabit Ethernet X2 card or the 8-port 10GBASE-T card. Cards can be inserted and removed online. The half card weighs 1.5 lb (0.7 kg) and the spare number is WS-X4904-10GE=.
Its four ports take X2 modules, and the 4900M X2 range includes X2-10GB-SR=, X2-10GB-LR=, X2-10GB-ER=, X2-10GB-LRM=, X2-10GB-LX4=, X2-10GB-CX4= and X2-10GB-ZR=. The TwinGig Converter Module for Gigabit Ethernet SFPs is supported only on the 8-port 10 Gigabit Ethernet X2 half card, not on this one.
The 4900M needs Cisco IOS Software Release 12.2(46)SG or later. For copper 10GBASE-T, see the WS-X4908-10G-RJ45 half card, or look at the WS-C4900M switch and the Cisco switches.
