WS-C4948-10GE-E Cisco Catalyst 4948-10GE Enterprise Services Switch

The WS-C4948-10GE-E is a Cisco Catalyst 4948-10GE 48-port Gigabit switch with the Enterprise Services software image, one AC power supply and a fan tray. That image adds OSPF, EIGRP, IS-IS, BGP, IPX and AppleTalk routing and carries every IP Base feature. The fixed-configuration 1RU chassis has 48 wire-speed 10/100/1000BASE-T ports plus 2 wire-speed 10 Gigabit Ethernet ports for X2 optics.

Switching capacity is 136 Gbps with a forwarding rate of 102 mpps for Layer 2 to 4 traffic. The hardware holds 64,000 TCAM entries, 55,000 MAC addresses and 4096 active VLANs, with a 16 MB shared buffer, a 666 MHz CPU and 256 MB of SDRAM. A dedicated 10/100 console port and a separate 10/100 management port handle local and out-of-band access. The chassis is 17.290 in. (43.92 cm) wide and 16.14 in. (41.00 cm) deep, and it weighs 16.5 lb (7.48 kg) with one power supply.

Two internal 300 W power supplies can run as a 1+1 pair, AC and DC units can be mixed, and the switch also runs on one supply. The fan tray has four redundant fans and is hot-swappable, with the spare tray being the WS-X4991. The two X2 ports accept SR, LR, LRM, LX4, ER, ZR, CX4 and DWDM modules, among them the X2-10GB-SR. The base WS-C4948-10GE leaves the software image and power supplies optional, and the Cisco switch category has more.
