If the switch is RPS powered, look at the system status LED or RPS status LED to identify a power failure.
If the system status LED or RPS status LED is off, an RPS input failure has occurred. Check the following
items:
• The switch is well connected to the external RPS power supply.
The external RPS is correctly working.
•
The operating temperature of the switch is normal, and the power module has good ventilation
•
(over-temperature can cause the power module to stop working and enter the protection state).
Concurrent AC and RPS inputs
If the switch is concurrently powered by an RPS and an AC power supply, look at the power LED and RPS
status LED to identify an RPS or AC input failure.
If the power LED is off, the AC power supply and the RPS both have an input failure.
