Diagnostic Tips:
Ti Problem Solution
➊
The switch’s
power adapter
is not plugged
into an active
AC power
source, or the
power adapter
may have failed.
1. Verify the AC power adapter 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 in the power.
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.
If this condition persists, the switch’s power
adapter may have failed. Call your ProCurve
Networking authorized network reseller, or use
the electronic support services from ProCurve
Networking to get assistance. See the Customer
Support/Warranty booklet for more information.
