Solution
➊
The switch is not
plugged into an active
AC power source, the
switch’s power adapter
may have failed.
1. Verify the power cord is plugged into an active power source and to
the switch. Make sure these connections are snug.
2. Try power cycling the switch by unplugging and plugging the power
cord back in.
3. If the Power LED is still not on, verify that 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.
