Troubleshooting
Diagnosing Switch Indicators
The switch can be easily monitored through panel indicators to assist the network
manager in identifying problems. This section describes common problems you may
encounter and possible solutions.
Symptom: Link indicator does not light up (green) after making a connection.
Cause:
Network interface (e.g., a network adapter card on the attached device),
network cable, or switch port may be defective.
Solution:
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.
Symptom: Power indicator does not light up (green) after power on.
Cause:
Power outlet, power cord, or internal power supply may be defective.
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 an
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 fans on back 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.
Communication Mode
Verify that each port is set to the same communication mode used by the attached
device (i.e., half or full duplex). You can configure the ports using the Configure button,
via the console port, or AccView/Open. RJ-45 ports can use auto-negotiation to set the
communication mode. However, if the attached device does not support auto-
negotiation and needs to operate at full duplex, then you must manually configure the
port.
Port and Cable Assignments
RJ-45 Port Description
RJ-45 station ports (MDI-X) can be attached to any
devices which use a standard network interface
(e.g., a workstation, server, bridge or router). RJ-45 daisy-chain ports (MDI) can be
cascaded to a station port on similar networking devices (e.g., another switch or hub).
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45
connections: 100
W
Category 3, 4 or 5 cable for 10 Mbps connections or 100
W
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).
