Troubleshooting

This troubleshooting section is intended to help you solve the most common problems on the DES-5016.

The Diagnostic LED displays a code if there is a problem on the DES-5016. If an error cannot be resolved by implementing the solutions in this section, contact D-Link Technical Support.

All LEDs are explained in detail in Chapter 4, LEDs. If you are having a problem that is not discussed here, contact technical support.

Problem	Solution
POST Errors	The DES-5016 performs a Power On Self Test (POST) every time
	it is powered on. If you are connected to the DES-5016 through
	Local Console Management during the POST you can see the
	results displayed on your monitor. The login screen appears after
	the DES-5016 has completed the POST.
	The POST checks all of the hardware components on the DES-
	5016. See Table 9: Diagnostic LED for proper actions.
Cables	Faulty cable is the most common source of problems on Ethernet
	and Fast Ethernet networks. Check the cable first if you are having
	any problems connecting to a device.
	Ethernet is more fault tolerant than Fast Ethernet. If you are
	moving from Ethernet to Fast Ethernet, make sure the cables are
	pinned out correctly. See Chapter 3, Connecting the DES-5016 to
	the Network, Cable Specifications, for a diagram showing the
	proper pin arrangement for Ethernet and Fast Ethernet.
Port States	All ports on the DES-5016 have two modes: auto negotiation mode
	and forced mode. Ports in auto negotiation mode auto negotiate the
	proper speed and duplex mode. Ports in forced mode have been
	manually set to a particular speed and duplex mode. Check the
	LEDs on the DES-5016 and on the link partner to verify settings.
	See Chapter 4, LEDs, for an explanation of all LEDs.
	The port settings on the DES-5016 and the port settings on the
	device you are connecting to must be the same in order for them to
	communicate. Check the speed and duplex setting on both the port
	and device you are connecting to.

Power LED is Off Check the three pronged power plug and verify that you are getting power from the wall socket. If the DES-5016 is on and the power
