CISCO CATALYST 4948-10GE SWITCH
10 Gigabit Ethernet Switching for High-Performance, Rack-Optimized Server Switching
PRODUCT OVERVIEW
®
®
The Cisco
Catalyst
4948-10GE Switch is a wire-speed, low-latency, Layer 2–4, 1-rack-unit (1-RU), fixed-configuration switch for rack-optimized
server switching. Based on the proven Cisco Catalyst 4500 Series hardware and software architecture, the Cisco Catalyst 4948-10GE offers
exceptional performance, bandwidth, and reliability for low-density, multilayer aggregation of high-performance servers and workstations.
The Cisco Catalyst 4948-10GE offers 48 ports of wire-speed 10/100/1000BASE-T with 2 ports of wire-speed 10 Gigabit Ethernet (X2 optics).
Exceptional reliability and serviceability are delivered with optional internal AC or DC 1+1 hot-swappable power supplies and a hot-swappable
fan tray with redundant fans (Figures 1 and 2).

Summary of Contents for Cisco 4948

  • Page 1 The Cisco Catalyst 4948-10GE offers 48 ports of wire-speed 10/100/1000BASE-T with 2 ports of wire-speed 10 Gigabit Ethernet (X2 optics). Exceptional reliability and serviceability are delivered with optional internal AC or DC 1+1 hot-swappable power supplies and a hot-swappable fan tray with redundant fans (Figures 1 and 2).
  • Page 2: Key Features And Benefits

    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 maximum deployment flexibility. The Cisco Catalyst 4948-10GE also has a hot-swappable fan tray with four redundant fans for additional serviceability and availability.
  • Page 3 INTELLIGENT NETWORK SERVICES WITH QOS AND SOPHISTICATED TRAFFIC MANAGEMENT The Cisco Catalyst 4948-10GE offers superior per-port quality of service (QoS) features to help ensure that network traffic is classified, prioritized, and scheduled optimally to efficiently manage bandwidth-hungry multimedia, and time-sensitive and mission-critical applications. The Catalyst 4948-10GE can classify, police, and mark incoming packets, allowing the administrator to differentiate between traffic flows and enforce policies.
  • Page 4: Features At A Glance

    Sharing, shaping, and strict-priority configurations determine scheduling of egress traffic. The Catalyst 4948-10GE also supports Dynamic Buffer Limiting (DBL), a congestion-avoidance feature. For details about the QoS features (including DBL) on the Catalyst 4948-10GE, refer to the QoS on Cisco Catalyst 4500 Series supervisor engines overview at: http://www.cisco.com/en/US/partner/products/hw/switches/ps4324/prod_white_papers_list.html...
