Solution
You can reset the hub three five different ways:
• From the device, remove the plug on the power
cord from the power source or the hub and
reconnect it.
• From the device, press the Reset Button.
• From the ASCII Console Interface, select either
the Reboot Hub option to preserve your settings
or select the Reset Hub to Factory Default option
to completely reset the hub's factory defaults.
• From the Browser Interface, select the Factory
Reset Button.
• From HP Top Tools for Hubs and Switches,
perform a reset from the Reset Parameters
dialog box.
If this condition persists, see your LAN dealer.
Verify that the power cord 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 that the AC
source works by plugging another device into the
outlet. Or try plugging the hub into a different outlet
or try a different power cord.
If this condition persists, call your
HP-authorized LAN dealer or HP representative for
assistance.
