Problem
Solution
1
Both switch power supplies
are not plugged into an active
AC power source.
Verify the AC power source works by plugging another device into
the outlet. Or try plugging the power supplies into different outlets
or try different power cords.
If the problem is still not resolved, both power supplies may be
faulty.
2
The PSU with the LED off is
not plugged into an active AC
power source or has failed.
Verify the power cord is plugged into an active power source and
to the power supply. Make sure these connections are snug.
If the PS1/PS2 LED is still not on, verify the AC power source works
by plugging another device into the outlet. Or try plugging the
switch into a different outlet or try a different power cord.
If the power source and power cord are OK and this condition
persists, the switch power supply may have failed. Call your Aruba
authorized network reseller, or use the electronic support services
from Aruba to get assistance.
3
The PSU with the LED on or
flashing amber has faulted.
Try power cycling the PSU or removing and re-inserting the PSU.
If the condition persists, the switch power supply has failed. Call
your Aruba authorized network reseller, or use the electronic
support services from Aruba to get assistance.
4
The PSU with the LED flashing
green has been disabled by
software.
This occurs when the power supply does not match the defined
system airflow. The PSU release tab should be a different color
than the other supply and the fan trays.
Replace power supply with one with the correct airflow. See
5
Fan tray with the flashing
amber LED may have failed or
uses incorrect airflow
direction.
Check the airflow direction and replace with the correct fan tray if
needed. Otherwise, try removing the fan tray and re-inserting. See
If the condition persists, the fan tray has failed.
