Additional Information
Manufacturer CISCO Manufacturer Part Number WS-X4548-GB-RJ45 SKU GROUP-213465 Ethernet Technology Gigabit Ethernet Marketing Information 48-port 10/100/1000-Mbps Gigabit Ethernet (RJ-45) WS-X4548-GB-RJ45 (power-efficient). This module, with multispeed autosensing, autonegotiating technology, provides wiring-closet investment protection by allowing Fast Ethernet desktops to migrate to Gigabit Ethernet in the future, without replacing the switch line cards
Description The Cisco Catalyst 4500 E-Series 48-port Gigabit Ethernet line cards provide high-performance 10/100/1000 switching at 24 Gbps per slot. The Cisco Catalyst 4500 48-port 10/100/1000 E-Series line cards are designed for LAN access applications where desktop users require gigabit connection speeds. The Cisco Catalyst 4500 48-port 10/100/1000 E-Series line cards are available in two versions: one with standard PoE 802.3af, and the second one with standard PoE 802.3af and PoEP ready features such as support for up to 30 Watts per port.

Interfaces/Ports Details 48 x RJ-45 10/100/1000Base-T Auto-sensing/Auto-negotiating LAN Limited Warranty 90 Manageable Yes Management Port Yes Maximum Data Transfer Rate 100 Mbit/s Media Type Twisted Pair Memory Card Supported CompactFlash Alt Part No WSX4548GBRJ45 Network Technology 10/100/1000Base-T Product Type Switching Module 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.
