The Catalyst 4948E is a fixed 1RU switch with 48 10/100/1000 RJ-45 ports and four uplink ports that take either 1 GbE SFP or 10 GbE SFP+ optics. This -E version ships with the Enterprise Services software tier, the higher of the two orderable tiers.

Switching capacity is 176 Gbps with a forwarding rate of 131 mpps for IPv4 and 110 mpps for IPv6, and a 17.5 MB shared buffer. The control plane uses a 1 GHz CPU with 1 GB of SDRAM, and the minimum software is Cisco IOS 12.2(54)SG. Table sizes are 55,000 MAC addresses, 57,000 routes, 28,000 multicast routes, 32,000 security and QoS entries and 4,094 VLANs, with 8 ingress and 8 egress SPAN sessions.

The hot-swappable fan tray moves 28 CFM at low speed and 44 CFM at maximum, with front-to-back airflow.
