The switch uses removable power supplies. Examine the system status LED of the switch to identify
power supply failure.
Symptom
The system status LED is not steady green.
Solution
To resolve the issue:
1. Verify that the switch 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
supply has good ventilation.
4. If the issue persists, contact Hewlett Packard Enterprise Support.

Fan module failure
!
Do not power on the switch when the
switch does not have any fan modules or has only one fan
module installed.
If both fan modules fail during operation, replace them within 2 minutes while the switch is
operating.
If one fan module fails, perform either of the following tasks:
If the ambient temperature is not higher than 27°C (80.6°F), replace the fan module within 24 hours
and make sure the failed fan module remains in position before the replacement.
If the ambient temperature is higher than 27°C (80.6°F), replace the fan module immediately.
The switch uses removable fan modules. Examine the system status LED of the switch and the fan
module status LED to identify fan module failure.
