Check the
power
indicator
(marked

switch.
Check the
running
indicator
(marked SYS)
of the switch.
The PWR
indicator is
steady green.
The SYS
indicator is
blinking
green.
Take corrective measures based
on the PWR indicator status:
● Off: The power supply unit
(PSU) is not detected, or the
board power supply is
abnormal when the switch is
configured with one PSU.
● Steady red, The possible
causes are as follows:
Two PSUs configured on the
switch are detected, but the
circuit breaker is off.
The power supply is
disconnected.
Both the board and power
over Ethernet (PoE) power
supplies are faulty.
● Steady orange: When the
switch is configured with one
PSU, the PoE power supply is
abnormal. When the switch is
configured with two PSUs, the
board or PoE power supply is
abnormal.
Take corrective measures based
on the SYS indicator status:
● Off: The switch is not running.
● Steady green: The switch is
not running properly or is
starting.
● Steady orange: The indicator
takes a self-test during
startup.
● Steady red: The switch does
not run properly after being
registered, or alarms
indicating that the power
supply, fan, or temperature is
abnormal are generated.
