||Catalyst 4900M AC Power Supply
The Cisco® Catalyst® 4900M Series is designed for data center network top of rack switching and midmarket collapsed core/distirbution. Optimized for ultimate deployment flexibility for the data center, the Cisco Catalyst 4900M can be deployed for 10/100/1000 server access with 1:1 uplink-to-downlink oversubscription and a mix of 10/100/1000 and 10 Gigabit Ethernet servers or all 10 Gigabit Ethernet server environments. The Cisco Catalyst 4900M is a 320-Gbps, 250 million packets per second (mpps), two-rack-unit (2RU) fixed-configuration switch with 8 fixed wire-speed X2 ports on the base unit and 2 optional half-card slots for deployment flexibility and investment protection. Low latency, scalable buffer memory, and high availability with 1+1 hot swappable AC or DC power supplies and a field replaceable fan tray optimize the Cisco Catalyst 4900M for any size of data center.
For the midmarket collapsed core/distribution and in branch, the Cisco Catalyst 4900M provides an ideal solution for space-constrained deployments that require high-performance wire-speed services and high availability. With the unique semifixed archiecture and support of the TwinGig converter, the Cisco Catalyst 4900M can be used in a collapsed core distribution LAN deployment with the flexibility of deploying Gigabit Ethernet now, and cost-effectively migrate to 10 Gigabit Ethernet as requirements change. The Cisco Catalyst 4900M configuration provides wire-speed connection, buffers to handle bursty traffic, and a comprehensive set of Layer 3 features required at the collapsed core/distribution of the network. The Cisco Catalyst 4900M also supports a suite of ease of management features to simplify operations.
