Features of 4948 10 GE Switch
Wire-Speed Performance in All Directions
The Cisco Catalyst 4948 10 Gigabit Ethernet Switch delivers wire-speed throughput with low latency for data-intensive applications using a 136-Gbps switching fabric with a forwarding rate of 102 million packets per second (mpps) in hardware for Layer 2 to 4 traffic. High-performance switching is maintained regardless of the number of route entries or Layer 3 and 4 services enabled.
Power-Supply Redundancy for Nonstop Operation
The Cisco Catalyst 4948 10 Gigabit Ethernet Switch provides reliability for critical applications with 1+1 redundant, hot-swappable internal AC or DC power supplies. The 1+1 power supply design provides A-to-B failover when power supplies are connected to different circuits. AC and DC power supplies can be mixed in the same unit for outstanding deployment flexibility.
