Diagnostic Tips
Tip Problem Solution
1 The switch is not plugged into
an active AC power source, or
the switch power supply may
have failed.
1. Verify that the power cord is plugged into an active
power source and to the switch. Make sure that
these connections are snug.
2. Try power cycling the switch by unplugging and
plugging the power cord back in.
3. If the power supply 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 con-
dition persists, the switch power supply may have failed.
Call your Hewlett Packard Enterprise authorized net-
work reseller.
2 A switch hardware failure has
occurred. All the LEDs will stay
on indefinitely.
Try power cycling the switch. If the fault indication
reoccurs, the switch may have failed. Call your Hewlett
Packard Enterprise authorized network reseller.
3 The switch has experienced a
software failure during self-
test.
1. Try resetting the switch by pressing the Reset
button on the front of the switch, or by power
cycling the switch.
2. If the fault indication reoccurs, attach a console to
the switch (as indicated in chapter 2) and
configure it to operate. Then, reset the switch.
Messages then appear on the console screen and
in the console log to identify the error condition.
You can view the console log at that point by
selecting it from the console Main Menu.
If necessary to resolve the problem, contact your
Hewlett Packard Enterprise authorized network
reseller.
