System Diagnostics

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 should turn itself
off after running for a while, check for loose power connections, power loss 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 supplier 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.

Transmission Mode

The selections of the transmission mode for the RJ-45 ports are auto-negotiation using the default method. Therefore, if

the Link signal is disrupted (e.g., by unplugging the network cable and plugging it back in again, or by resetting the
power), the port will try to reestablish communications with the attached device via auto-negotiation. If auto-negotiation
fails, then communications are set to half duplex by default. Based on this type of industry-standard connection policy, if
you are using a full-duplex device that does not support auto-negotiation, communications can be easily lost (i.e., reset
to the wrong mode) whenever the attached device is reset or experiences a power fluctuation. The best way to resolve
this problem is to upgrade these devices to version that will support auto-negotiation.
