Removable power module failure
Symptom
S5560X-EI switches except the S5560X-34S-EI and S5560X-54S-EI use removable power
modules.
•
To identify the operating status of a power module on the S5560X-30C-EI, S5560X-54C-EI,
S5560X-30F-EI, and S5560X-54F-EI switches, observe the PWR LED on the front panel of the
switch. For more information about the power module status LED on the front panel of the
switch, see LEDs in Hardware Information and Specifications.

To identify the operating status of a power module on the S5560X-30C-PWR-EI and
S5560X-54C-PWR-EI switches, observe the LEDs on the power module and the PWR LED on
the front panel of the switch. For more information about the LEDs on a power module, see H3C
PSR360-56A Power Module User Manual, H3C PSR560-56D Power Module User Manual,
H3C PSR720-56A Power Module User Manual, or H3C PSR1110-56A Power Module User
Manual.
Solution
To resolve the issue:
1.
Verify that the power cord is correctly connected.
2.
Verify that the power source meets the requirement.
3.
Verify that the operating temperature of the switch is in an acceptable range and the power
module has good ventilation.
4.
If the issue persists, contact H3C Support.

Fixed fan tray failure
The S5560X-30F-EIF, S5560X-34S-EI, and S5560X-54S-EI switches each use a fixed fan tray. If the
fan tray fails, contact H3C Support.
Removable fan tray failure
WARNING!
• If both fan trays fail during switch operation, replace them within 2 minutes.
• 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 remains in position before the replacement.
If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray immediately.
The S5560X-EI switches except the S5560X-34S-EI and S5560X-54S-EI use removable fan trays. If
a fan tray fails, see
