Management Ports
The Catalyst 2948G, 2948G-GE-TX, and 2980G switches have two kinds of
management ports: console serial and Ethernet. The Catalyst 2948G switches
have a 10BASE-T management port. The Catalyst 2948G-GE-TX and 2980G-A
switches have a 10 /100BASE-T mana gement port.
Table1-2 on p age 1-9 lists the management options for the switches.

Console Serial Port

An RJ-45 console serial port allows you to perform switch-management functions
using a terminal. See TableA-1 on page A-1 for the console connector pi nouts .

10BASE-T and 10/100BASE-T Ports

An RJ-45 10BASE-T port allows you to perform TCP/IP switch-management
functions (Telnet, SNMP, FTP), configure IP addresses with BOOTP, and
download software images.
Note The Catalyst 2948G-GE-TX and 2980G-A switches have a 10/100BASE-T
management port.
This port is for network management only; it is not for switching. Connectivity is
not available between this port and the 10/100BASE-T switching ports.
Front Panel LEDs
The LEDs on the front panels of the Catalyst 2948G, 2948G-GE-TX, and2 980G
switches perform the following functions:
•STATUS LEDs indicate the operating state of the switches.
•Link Status LEDs provide management and indicate switching port status.
