The Cisco Catalyst WS-C4948-S 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. High performance and scalability of intelligent network services is made possible with dedicated specialized resources known as ternary content addressable memory (TCAM). Ample TCAM resources (64,000 entries) enable "high feature capacity," which provides wire-speed routing/switching performance with concurrent provisioning of services such as QoS and security. This helps ensure scalability for today's network requirements with ample room for future growth.

The Cisco Catalyst WS-C4948-S 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. The Cisco Catalyst 4948 10 Gigabit Ethernet Switch offers a choice of 300-watt (W) AC or DC power supplies. The switch can operate with one power supply present. When two power supplies are installed, the switch shares the power load between the two supplies.

The Cisco Catalyst 4948 has 52 physical switching ports (48 10/100/1000 and four SFP) on the front panel. Up to 48 of these ports can be active at one time in any combination.
