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.
Try power cycling the PSU or removing and re-inserting the PSU.

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
