1.3.5 System Status LEDs

Note:
When two SRPUs are configured on an S7506R Ethernet switch, all the other LEDs on
the standby SRPU are constantly OFF except the LEDs of the SRPG.
I. Board LEDs
SRPG: The LEDs of the SRPG show the status of the SRPU.
LPU1, LPU2, LPU3 (LPU4, LPU5, LPU6): The LEDs of these LPUs respectively show
the status of three LPUs (for the S7503), or six LPUs (for the S7506 or S7506R).

RUN (Green)

Note:
If the RUN LED blinks fast, the board is booting but does not operate normally. During
the initialization of the system, the ALM LED will be on for a while, but this does not
mean that the board is faulty.
II. Power LEDs (PWR1, PWR2 and PWR3)
PWR1, PWR2 and PWR3: The LEDs of the PWR1, PWR2 and PWR3 respectively
show the status of the three (AC or DC) power modules.
