Maintenance and troubleshooting
Power supply failure
You can use the LEDs on the power supply to identify a power supply failure. For more information
about the LEDs on a power supply, see HPE A58x0AF 650W AC (JC680A) & 650W DC (JC681A)
Power Supplies User Guide or HPE FlexFabric Switch 650W 48V Hot Plug NEBS Compliant DC
Power Supply (JH336A) User Guide.
The LEDs on the power supply are steady green (active) or flashing green (standby) while the power
supply system is correctly operating. If the LEDs behave in any other way, verify the following items:
• The switch power cord is correctly connected.
• The power source meets the requirement.
• The operating temperature of the switch is in the normal range and the power supply has good
ventilation.
If the problem persists, contact Hewlett Packard Enterprise Support.
To replace a power supply, see "Installing/removing a power supply."
Fan tray failure
When an LSWM1HFANSC or LSWM1HFANSCB fan tray has problems, the system status LED on
the switch is steady red and the system outputs alarm messages.
When an LSWM1BFANSC or LSWM1BFANSCB fan tray has problems, the Alarm LED on the fan
tray is steady yellow and the system outputs alarm messages.
To replace a failed fan tray, see "Installing/removing a fan tray."
Follow the
se guidelines when you install or remove a fan tray:
• Do not power on the switch when the switch has no fan trays installed.
• You must install two fan trays of the same model for the switch.
• When a fan tray fails during the switch operation and the ambient temperature is not higher than
27°C (80.6°F), replace the fan tray within 24 hours and keep the failed fan tray in position before
replacement. If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray
immediately.
• Make sure all slots have a module or filler panel installed when the switch is operating.
• When two fan trays fail during the switch operation:
{ Finish replacing the fan trays within 2 minutes on an HPE 5930-32 QSFP+/HPE 5930-32
QSFP+ TAA/HPE 5930-2Slot+2QSFP+/HPE 5930-2Slot+2QSFP+ TAA switch.
{ Finish replacing the fan trays within 1 minute on an HPE 5930-4Slot/HPE 5930-4Slot TAA
switch.
Configuration terminal problems
If the configuration environment setup is correct, the configuration terminal displays booting
information when the switch is powered on. If the setup is incorrect, the configuration terminal
displays nothing or garbled text.
