Solution: 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, have the unit's power supply replaced by a qualified
Accton distributor.
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 fan on back of the unit is 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.
Port and Cable Assignments
RJ-45 Port Description
RJ-45 (MDI-X) station ports can be attached to any devices which use a standard
network interface (e.g., a workstation, server, bridge or router). RJ-45 (MDI) daisy-
chain ports can be cascaded to a station port on similar networking devices (e.g.,
another hub or switch). Use unshielded twisted-pair (UTP) or shielded twisted-pair
(STP) cable for RJ-45 connections: 100W Category 3, 4 or 5 cable for 10 Mbps
connections or 100W Category 5 cable for 100 Mbps connections. Also be sure that
the length of any twisted-pair connection does not exceed 100 meters (328 feet).
