Certain Cisco LRE customer premises equipment (CPE) devices are not supported
by certain Catalyst 2950 LRE switches. In Table 2-1, Yes means that the CPE is
supported by the switch; No means that the CPE is not supported by the switch.
Front-Panel Description
The switch front panel contains the ports, the LEDs, and the Mode button.
Other than the Catalyst 2950ST-24 LRE 997 switch, the front panel of the
Catalyst 2950 LRE switches also contains the console port and AC power
connector. On the Catalyst 2950ST-24 LRE 997 switch, the front panel contains a
DC power connector (also referred to as the terminal block header), a DC ground
lug, and an RJ-45 console port.
For more information about the power connectors on the LRE switches, see the
“Power Connectors” section on page 2-29. For more information on the console
port on these switches, see the “Console Port” section on page 2-31.
