Port LEDs and Modes
Each of the 10/100, 100BASE-FX, and LRE ports and module slots have a port
LED. These port LEDs, as a group or individually, display information about the
switch and about the individual ports. The port modes (
Table 1-4 and Table 1-5 )
determine the type of information displayed.
To select or change a mode, press the Mode button until the desired mode is
highlighted. When you change port modes, the meaning of the port LED colors
also changes.
Table 1-6 and Table 1-7 list the port LED colors.
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).
