The Cisco Catalyst 4500 Series offers 48-port Classic Gigabit Ethernet Line Card for wiring closets and server farms, enabling high-density gigabit connectivity to the desktop and servers over Category 5 copper cabling. This module provide wiring closet investment protection by allowing Fast Ethernet desktops to migrate to Gigabit Ethernet in the future without replacement of the switch line cards.

Cisco WS-X4548-GB-RJ45 Miscellaneous

Additional Information:

  • The 48 ports can burst to Gigabit Ethernet line rate and can share 12 Gbps of full-duplex bandwidth into the switching fabric
  • amount of oversubscription can be controlled simply by varying the number of ports used at 1000 Mbps
  • All ports use the standard IEEE 802.3x flow-control (pause frame) mechanism to control Gigabit Ethernet host traffic.
  • The WS-X4548-GB-RJ45 switching module have 48 oversubscribed ports in six groups of eight ports each:
    • Ports 1, 2, 3, 4, 5 ,6, 7, 8
    • Ports 9, 10, 11, 12, 13, 14, 15, 16
    • Ports 17, 18, 19, 20, 21, 22, 23, 24
    • Ports 25, 26, 27, 28, 29, 30, 31, 32
    • Ports 33, 34, 35, 36, 37, 38, 39, 40
    • Ports 41, 42, 43, 44, 45, 46, 47, 48
    • The eight ports within each group use common circuitry that effectively multiplexes the group into a single, nonblocking, full-duplex Gigabit Ethernet connection to the internal switch fabric. For each group of eight ports, frames received are buffered and sent to the common Gigabit Ethernet link to the internal switch fabric. If the amount of data received for a port begins to exceed buffer capacity, flow control sends pause frames to the remote port to temporarily stop traffic and prevent frame loss.
