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 2-4 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 2-5 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 “Starting Express Setup”
section on page 1-5 and the “Clearing the Switch IP Address and Configuration”
section on page 4-2 for more information.
Solid amber The RPS is in standby mode or in a fault condition. Press the Standby/Active button
on the RPS, and the LED should turn green. If it does not, the RPS fan could have
failed. Contact Cisco Systems.
Blinking amber The internal power supply in a switch has failed, and the RPS is providing power
to the switch (redundancy has been allocated to this device).
