• The external AC/–48 VDC/RPS power supply system is operating properly.
• The switch is well connected to the external power system.
• 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).
2. The system status LED is on but the RPS status LED is steady yellow, 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 AC external power supply system is normal.
3. If the system status LED is on but the RPS status LED is off, an RPS input failure has occurred.
Check the following items:
• The power cord is correctly connected, the DC power receptacle of the switch is operational, and
the power socket is normal.
• The external –48 VDC/RPS power supply system is operating properly.
• The switch is well connected to the external power supply.
NOTE:
If the problem persists, contact your local sales agent or service engineer.
Fan failure
You can look at the system status LED and the seven-segment LED of an S3600V2 switch to identify a fan
failure. If both LEDs are behaving as described in
Table 7 , a fan failure occurs.

LED Mark State
System status LED PWR Steady red
Seven-segment LED Unit
The LED displays F for fan failure.
The S3600V2 Switch Series uses fixed fans. If a fixed fan failure occurs, you cannot solve the problem
yourself. Contact your sales agent or service engineer.
NOTE:
To ensure the normal operation of the switch, contact the local sales agent or service engineer as soon as
possible when a fixed fan failure occurs.
