For the S5560-30C-PWR-EI and S5560-54C-PWR-EI, examine the PWR1 or PWR2 LED of the switch and
the LEDs on the power module to identify power module failure.
• For more information about the PWR1 and PWR2 LEDs on the front panel of the switch, see Table
24 .
• For more information about the LEDs on a power module, see H3C PSR360-56A Power Module
User Manual, H3C PSR720-56A Power Module User Manual, and H3C PSR1110-56A Power
Module User Manual.
S5560-30F-EI, S5560-30C-EI, S5560-54C-EI, S5560-30C-PWR-EI, S5560-54C-PWR-EI, or
S5560-54QS-EI power module failure
• Symptom
The power module status LEDs are not steady green.
• Solution
To resolve the problem:
a. Verify that the switch power cord is correctly connected.
b. Verify that the power source meets the requirement.
c. Verify that the operating temperature of the switch is in an acceptable range and the power
module has good ventilation.
d. If the problem persists, contact H3C Support.

Fan failure
Fixed fan failure
The S5560-30S-EI and S5560-54S-EI switches use fixed fans. If a fan failure occurs, contact H3C
Support and do not attempt to fix the problem yourself.
Hot swappable fan tray failure
WARNING!
• If both fan trays fail during operation, replace them within 2 minutes while the switch is operating.
• If one fan tray fails, perform either of the following tasks:
{
If the ambient temperature is not higher than 27°C (80.6°F), replace the fan tray within 24 hours and make
sure the failed fan tray is in position before the replacement.
{
If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray immediately.
This section applies to the S5560-30F-EI, S5560-30C-EI, S5560-54C-EI, S5560-30C-PWR-EI,
S5560-54C-PWR-EI, and S5560-54QS-EI switches.
