  • 1. Cisco Catalyst 4900M SwitchHigh-Performance Small Form-Factor Cisco Catalyst Switch with Flexibility andInvestment Protection for Top-of-Rack Switching or Midmarket Collapsed Core andAggregation Layer DeploymentProduct OverviewThe CiscoCatalyst 4900M Switch is designed for data center network top-of-rackswitching and midmarket collapsed core and aggregation layer deployment.Optimized for ultimate deployment flexibility for the data center, the Cisco Catalyst4900M can be deployed for 10/100/1000 or 1/10GBASE-T server access with 1:1uplink-to-downlink oversubscription and environments with a mix of 10/100/1000and 10 Gigabit Ethernet servers or all 10 Gigabit Ethernet servers.The Cisco Catalyst 4900M is a 320-Gbps, 250-million-packets-per-second (mpps),two-rack-unit (2RU) fixed-configuration switch with eight fixed wire-speed X2 portson the base unit and two optional half-card slots for deployment flexibility andinvestment protection. Low latency, scalable buffer memory, and high availabilitywith 1+1 hot-swappable AC or DC power supplies and a field-replaceable fan trayoptimize the Cisco Catalyst 4900M for data centers of any size.For the midmarket collapsed core and aggregation layer and in the branch office, theCisco Catalyst 4900M provides an ideal solution for space-constrained deploymentsthat require high-performance wire-speed services and high availability. With theunique semifixed architecture and support of the Cisco TwinGig Converter Module,the Cisco Catalyst 4900M can be used in a collapsed core and aggregation layer LANdeployment, providing the flexibility to deploy Gigabit Ethernet now andcost-effectively migrate to 10 Gigabit Ethernet as requirements change.The Cisco Catalyst 4900M configuration provides wire-speed connection, buffers tohandle bursty traffic, and a comprehensive set of Layer 3 features required at thecollapsed core and aggregation layer of the network. The Cisco Catalyst 4900M alsosupports a suite of ease-of-management features to simplify operations.
  • 2. Features and BenefitsThe Cisco Catalyst 4900M half cards provide a wide variety of combinations ofGigabit Ethernet and 10 Gigabit Ethernet media types. The base unit canaccommodate up to two of the half cards shown in Figures 2, 3, 4, and 5, in anycombination.Figure2. 20-Port Wire-Speed 10/100/1000 (RJ-45) Half CardFigure3. 4-Port Wire-Speed 10 Gigabit Ethernet (X2) Half CardFigure4. 8-Port (2:1) 10 Gigabit Ethernet (X2) Half Card (Compatible with CiscoTwinGig Converter Module)Figure5. 8-Port (2:1) 10GBASE-T RJ-45 Half Card1 (Capable of Operating at 1G/10G forUp to 100m on Cat6a/Cat7 Cable)
  • 3. In addition to deployment flexibility, the half slots provide investment protection forfurther additions of Gigabit Ethernet and 10 Gigabit Ethernet media.Table 1 summarizes the features and benefits of the Cisco Catalyst 4900M.Table1.
