Power and Cooling Problems
If the power indicator does not turn on when the power cord is plugged in, you may
have a problem with the power outlet, power cord, or internal power supply as
explained in the previous section. However, if the unit powers off after running for a
while, check for loose power connections, power losses or surges at the power outlet,
and verify that the fans on the right side of the unit are unobstructed and running
prior to shutdown. If you still cannot isolate the problem, then the internal power
supply may be defective. In this case, contact your Accton distributor for assistance.
Installation
Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (e.g., the power cord or network cabling),
test them in an alternate environment where you are sure that all the other
components are functioning properly.
Symptom Cause Solution
Power indicator
does not light up
after power on.
Power outlet, power
cord, or internal power
supply may be
defective.
Check the power outlet by plugging in another device
that is functioning properly. Check the power cord with
another device. If these measures fail to resolve the
problem, contact your Accton distributor.
Link indicator
does not light up
after making a
connection.
Network interface (e.g.,
a network adapter card
on the attached
device), network cable,
or switch port may be
defective.
Verify that the switch and attached device are
powered on. Be sure the cable is plugged into both the
switch and corresponding device. Verify that the
proper cable type is used and its length does not
exceed specified limits. Check the adapter on the
attached device and cable connections for possible
defects. Replace the defective adapter or cable if
necessary.
Mgmt indicator
does not light up
after power on.
A Management Module
is not installed
correctly, or may have
failed.
Check that the Management Module is correctly
installed in the upper slot on the switch rear panel (at
least one Management Module is required in a switch
stack). Test the Management Module by installing it in
another switch unit. If these measures fail to resolve
the problem, contact your Accton distributor.
Module 1/2 Status
indicator does not
light up after power
on.
A optional module is
not installed correctly,
or may have failed.
Check that the module is correctly installed in one of
the two lower slots on the switch rear panel. Test the
module by installing it in another switch unit. If these
measures fail to resolve the problem, contact your
Accton distributor.
Switch ID LCD
does not display a
stable unit number.
The switch stack has
not initiated properly.
Reset the stack by powering off each switch unit in the
stack and then powering them back on. Check all
Stacking Modules are installed correctly in the
lower-left slot on the rear panel of each switch. Check
that all stacking cables are connected correctly. If
these measures fail to resolve the problem, contact
your Accton distributor.
