An SFP or SFP+ transceiver must be installed in the chassis port socket for the port to operate. Cable type and recommended cabling distance for each port is determined by the type of SFP or SFP+ transceiver installed in the uplink port. A bicolor port link status LED is associated with each uplink port. LED colors indicate the following status: • Green-The link is established and operational. • Amber-The port is disabled. • Blinking amber-The system has detected a fault with the link. • Off-No link is established or the transceiver is not installed in the port socket. See Appendix B, "Transceiver, Chassis Connectors, and Cable and Adapter Specifications" for supported SFP and SFP+ transceiver descriptions, specifications, and cabling distances. • The chassis has 48 10/100/1000BASE autonegotiating-capable downlink ports. Each port has an RJ-45 connector. A bicolor port link status LED is associated with each port. LED colors indicate the following status: • Green-The link is established and operational. • Amber-The port is disabled. • Blinking amber-The system has detected a fault with the link. • Off-No link is established or no network interface cable is installed. A console serial port (RJ-45) is provided for switch management using standard console equipment. Additional information including a connector pinout table is provided in Appendix B, "Transceiver, Chassis Connectors, and Cable and Adapter Specifications" for the console port. Note A console cable is not provided in the accessory kit. It can be ordered as an option. • The Catalyst 4948E switch provides a 10/100/1000 RJ-45 port Ethernet Management port that can be used to manage the switch through an Ethernet network. This port can also be used to download software to the switch or transfer files to remote servers for analysis or backup storage. • The typical connection to the Management Ethernet port uses an Ethernet cable with RJ-45 connectors at each end. The other end of the cable typically connects to an Ethernet switch, hub, or router that provides connectivity between the multishelf system and networks from which system management is desired. Appendix B, "Transceiver, Chassis Connectors, and Cable and Adapter Specifications" contains additional information for the Ethernet management port including a connector pinout table.

Catalyst 4948E and Catalyst 4948E-F Switch Features
Feature
Description
Chassis
(both chassis)
1-RU, 48 10/100/1000 ports plus 4 1-GB/10-GB ports, fixed configuration
switch with redundant power supplies
Uplink ports
(both chassis)
The chassis has 4 1-GB or 10-GB uplink ports. An SFP or SFP+ transceiver
must be installed in the chassis port socket for the port to operate. Cable type
and recommended cabling distance for each port is determined by the type
of SFP or SFP+ transceiver installed in the uplink port. A bicolor port link
status LED is associated with each uplink port. LED colors indicate the
following status:
•
Green—The link is established and operational.
•
Amber—The port is disabled.
•
Blinking amber—The system has detected a fault with the link.
•
Off—No link is established or the transceiver is not installed in the port
socket.
See
Appendix B, “Transceiver, Chassis Connectors, and Cable and Adapter
Specifications”
for supported SFP and SFP+ transceiver descriptions,
specifications, and cabling distances.
Downlink ports
(both chassis)
•
The chassis has 48 10/100/1000BASE autonegotiating-capable
downlink ports. Each port has an RJ-45 connector. A bicolor port link
status LED is associated with each port. LED colors indicate the
following status:
•
Green—The link is established and operational.
•
Amber—The port is disabled.
•
Blinking amber—The system has detected a fault with the link.
•
Off—No link is established or no network interface cable is installed.
Console port
(both chassis)
A console serial port (RJ-45) is provided for switch management using
standard console equipment. Additional information including a connector
pinout table is provided in
Appendix B, “Transceiver, Chassis Connectors,
and Cable and Adapter Specifications”
for the console port.
Note
A console cable is not provided in the accessory kit. It can be ordered
as an option.
Ethernet management port
(both chassis)
•
The Catalyst 4948E switch provides a 10/100/1000 RJ-45 port Ethernet
Management port that can be used to manage the switch through an
Ethernet network. This port can also be used to download software to the
switch or transfer files to remote servers for analysis or backup storage.
•
The typical connection to the Management Ethernet port uses an
Ethernet cable with RJ-45 connectors at each end. The other end of the
cable typically connects to an Ethernet switch, hub, or router that
provides connectivity between the multishelf system and networks from
which system management is desired.
Appendix B, “Transceiver,
Chassis Connectors, and Cable and Adapter Specifications”
contains
additional information for the Ethernet management port including a
connector pinout table.
