The Cisco Catalyst 4928 10 Gigabit Ethernet Switch offers flexible and highly available aggregation solutions for
nonstop unified network services. Enterprise-grade features such as dynamic routing, dual hot-swappable power
supplies, and redundant field-replaceable fans enhance switch availability.
The switch is well-suited for space- and power-constrained deployments because of its compact 1RU form factor,
economical power needs, and efficient cooling. Ideally suited to support secure converged applications such as Cisco
TelePresence and Cisco Unified Communications, the switch delivers high-performance intelligent switching with its
robust feature set.
Wire-Speed Performance in All Directions:
The Cisco Catalyst 4928 10 Gigabit Ethernet Switch delivers wire-speed throughput with low latency for dataintensive
applications using a 96-Gbps switching fabric with a forwarding rate of 72 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. Hardware-based Cisco Express Forwarding routing architecture
enables increased scalability and performance. X2 10 Gigabit Ethernet optics provide 20 Gigabit Ethernet wire-speed
uplinks for maximum traffic throughput.
Power-Supply Redundancy for Nonstop Operations:
The Cisco Catalyst 4928 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. You can mix AC and DC power supplies in the same unit for
maximum deployment flexibility. The switch also has a hot-swappable fan tray with four redundant fans for additional
serviceability and availability.
Comprehensive Management:
The Cisco Catalyst 4928 10 Gigabit Ethernet Switch includes a single, dedicated 10/100 console port and a single,
dedicated 10/100 management port for offline disaster recovery and remote out-of-band management. Remote inband
management is available with the Simple Network Management Protocol (SNMP), Telnet Client, Bootstrap
Protocol (BOOTP), and Trivial File Transfer Protocol (TFTP).
The management port has two operating modes designed to increase operational efficiency and availability. When
the system is in Remote Monitoring (RMON) mode, the management port operates in a disaster-recovery mode. In
this state the operator can reload new Cisco IOS Software images from a TFTP server. During normal system
