Tip
Problem
Solution
1
The access point 
is not plugged 
into an active AC 
power source, or 
the access 
point’s AC power 
adapter may 
have failed.
1. Verify that the power cord is plugged into an active power source and to the access 
point's AC power adapter. Make sure these connections are secure.
2. Try power-cycling the access point 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 access point into a different outlet 
or try a different power cord.
If the power source and power cord are OK and this condition persists, the access point’s 
AC power adapter may have failed. Call your HP-authorized LAN dealer, or use the 
electronic support services from HP to get assistance. See the Customer Support/
Warranty booklet for more information.
