Power Module Failure
Hot Swappable Power Module Failure
The S5810 series switches support hot swappable power modules. You can check whether the power
system of the switch runs normally by viewing the PWR1 or PWR2 LED on the front panel and of the
switch the LED on the power module.

For details about the PWR1 and PWR2 LEDs on the front panel of the switch, refer to
Table 1-11
.

For details about the LED on a hot swappable power module, refer to
H3C PSR300-12A &
PSR300-12D1 Power Modules User Manual
.
When the power supply system functions normally, the corresponding power module LEDs should be
steady green. Otherwise, check whether
z
The power module is switched on. (If the power module provides no switch, ignore this step.)
z
The switch power cord is properly connected.
z
The power supply meets the requirement.
z
The operating temperature of the switch is normal and proper ventilation is ensured for the power
module.
If the cause cannot be located in the preceding steps and the problem persists, you need to contact
your local sales agent or service engineer.

Fan Failure
You can check the system status LED and the seven-segment LED of an S5810 series to determine
whether the fans operate normally. If a fan failure occurs, the two LEDs give an indication, as shown in
Table 6-1
