Switch LEDs
The Ethernet switch has a series of LEDs for monitoring the status of
the unit. There are system LEDs for monitoring the entire switch and
port LEDs for monitoring the individual data ports.
The system LEDs are Fault, Master, RPS (Redundant Power Supply),
and PWR. Figure 1-5 illustrates the location of the system LEDs. The
location of the system LEDs is the same on all switch models.
Figure 1-5 System LEDs
Table 1-2 describes the system LEDs on the Ethernet switch.

Description
Fault
Solid Red
The switch or management software is malfunctioning.
Flashing Red
The switch is booting, running diagnostic tests, writing
messages to FLASH, or transferring files using XMODEM.
OFF
Normal operation.
Master
Solid Amber
The switch is functioning as the master switch of the stack.
Off
The switch is functioning as a slave switch in the stack or is
not a part of a stack.
RPS (Redundant
Power Supply)
Solid Green
The RPS is connected to the switch. To verify that the RPS is
operating correctly, refer to the instructions in the RPS
Quick Install Guide.
Power
Solid Green
The switch is receiving power, the voltage is within the
acceptable range, and the power supply is working.
