Verify that the power supply is plugged into an
active power source and to the hub. Make
sure these connections are snug. Try power
cycling the hub by unplugging and plugging
the hub back in.
If the Power LED is still not on, verify the ac
source works by plugging another device into
the outlet. Or try plugging the hub into a
different outlet. If this condition persists, call
your HP-authorized LAN dealer or HP
representative for assistance.
