Chapter 6 Troubleshooting 55
2 One of the power
supplies is not plugged
into an active power
source, or the power
supply may have failed. Verify the AC power cord or DC power cable is connected to an active power
source and to the power supply. Make sure these connections are snug.
Use the “show environment power-supply” command to check the status of
the power supply.
Try power cycling the switch by disconnecting the power and connecting it to
the other working power supply.
If the PS1/PS2 LED is still not on, verify the power source works by
connecting another device to it. Or try connecting the switch to a different
power source or try a different AC power cord or DC power cable.
If the power source and power cable are OK and this condition persists, the
switch power supply may have failed. Call your Hewlett Packard Enterprise-
authorized network reseller, or use the electronic support services from
Hewlett Packard Enterprise to get assistance.
3 One of the switch fan
assemblies may have
failed. Try disconnecting power from the switch and wait a few moments. Then
reconnect the power to the switch and check the LEDs again. If the error
indication reoccurs, one of the fan assemblies has failed. The switch may
continue to operate under this condition if the ambient temperature does not
exceed normal room temperature, but for best operation, the fan assembly
should be replaced. Call your Hewlett Packard Enterprise-authorized network
reseller, or use the electronic support services from Hewlett Packard
Enterprise to get assistance.
