Cisco is the Internet networking worldwide leader. Cisco provides the broadest line of solutions for transporting data, voice and video within buildings, across campuses, or around the world. Cisco solutions ensure that networks both public and private operate with maximum performance, security, and flexibility. The Cisco Catalyst 4500 Series 48-Port 10/100/1000 RJ-45 module has efficient power draw.
Features
Device Type: Expansion module
Form Factor: Plug-in module
Data Link Protocol: Ethernet, Fast Ethernet, Gigabit Ethernet
The 48 ports can burst to Gigabit Ethernet line rate and can share 12 Gbps of full-duplex bandwidth into the switching fabric
The 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.
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.
