Data Sheet
Cisco Catalyst 4948 Series Switch
High-Performance, Rack-Optimized Server Switching
PRODUCT OVERVIEW
The Cisco
®
Catalyst
®
4948 is a wire-speed, low-latency, Layer 2–4, 1 rack unit (RU) fixed-configuration switch for rack-optimized server switching.
Based on the proven Cisco Catalyst 4500 Series hardware and software architecture, the Cisco Catalyst 4948 Series offers exceptional performance
and reliability for low density, multilayer aggregation of high performance servers and workstations.
The Cisco Catalyst 4948 offers 48 ports of wire-speed 10/100/1000BASE-T with 4 alternative wired ports that can accommodate optional
1000BASE-X Small Form-Factor Pluggable (SFP) optics*. Exceptional reliability and serviceability are delivered with optional internal
AC or DC 1 + 1 hot-swappable power supplies and a hot-swappable fan tray with redundant fans (refer to Figures 1 and 2).

KEY FEATURES AND BENEFITS
Wire-Speed Performance for 10/1 00/1 000 Connectivity
The Cisco Catalyst 4948 delivers wire-speed throughput with low latency for data-intensive applications using a 96 Gbps switching fabric with a
72 Mpps forwarding rate in hardware for Layer 2–4 traffic. Switching performance is guaranteed regardless of the number of route entries or
Layer 3 and 4 services enabled. Hardware-based Cisco Express Forwarding routing architecture allows for increased scalability and performance.
*
The Cisco Catalyst 4948 has 52 physical switching ports (48 10/100/1000 and 4 SFP) on the front panel. Up to 48 of these ports can be active at one time in
any combination.
