Description
Cisco WS-C4948E-F Switch:
The Cisco Catalyst 4948E and 4948E-F are wire-speed, low-latency, Layer 2-4, 1 rack unit (1 RU), fixed-configuration switches for rack-optimized server switching.
Based on the award-wining Cisco Catalyst 4948 hardware and software architecture, the Cisco Catalyst 4948E and 4948E-F double uplink capacity to four 10Gb Ethernet uplinks and supports IPv6 in hardware. In addition Cisco Catalyst 4948E and 4948E-F offer front-to-back and back-to-front cooling respectively for deployment flexibility.
The Cisco Catalyst 4948E and 4948E-F continue to offer the following features:
- Exceptional performance and reliability for high-density, multilayer aggregation of high-performance, rack optimized servers and workstations,
- 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
- Optional internal AC or DC 1 + 1 hot-swappable power supplies and a hot-swappable fan tray with redundant fans for exceptional reliability and serviceability
