Power supply failure

The V1910-24G-PoE (365W) adopts AC power input, RPS power input, or both RPS and AC power inputs.
Other 1910 switches adopt AC power input only.
You can look at the power LED and the RPS status LED on the front panel of the switch to identify a power
system failure.
AC input
If the switch is AC powered, look at the system status LED to identify a power failure. If the system status
LED is off, an AC input failure has occurred. Check the following items:
The AC power cord is well connected to the switch, and the AC receptacle on the switch and the AC
•
power receptacle are normal.
• The external AC power supply system is correctly working.
The operating temperature of the switch is normal, and the power module has good ventilation
•
(over-temperature can cause a power module to stop working and enter the protection state).
