RPS LED
The RPS LED shows the RPS status. Table 1-3 lists the LED colors and their meanings.
For more information about the Cisco RPS 300 or the Cisco RPS 675, see the documentation included
with the RPS.
Port LEDs and Modes
Each RJ-45 port and GBIC module slot has a port LED. These port LEDs, as a group or individually,
display information about the switch and about the individual ports. The port mode determines the type
of information displayed through the port LEDs.
Table 1-4 lists the mode LEDs and their associated port
modes and meanings.
To select or change a mode, press the Mode button (or Mode label on the Catalyst 3550-48 switch) until
the desired mode is highlighted. When you change port modes, the meanings of the port LED colors also
change.
Table 1-5 explains how to interpret the port LED colors in different port modes.
You can also use the Mode button to activate the Express Setup program or to clear the switch IP address
and all switch settings. See the
“Clearing the Switch IP Address and Configuration” section on page 3-1
for more information.
Green System is operating normally.
Amber System is receiving power but is not functioning properly.
