Fast Ethernet Switching System User's Guide 7 Troubleshooting This troubleshooting section is intended to help you solve the most common problems on the DES-5600. 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 POST Errors Cables Port States Solution The DES-5600 performs a Power On Self Test (POST) every time it is powered on. If you are connected to the DES-5600 through Local Console Management during the POST you can see the results displayed on your monitor.

See Chapter 3, Connecting the DES-5600 to the Network, Cable Specifications, for a diagram showing the proper pin arrangement for Ethernet and Fast Ethernet. TX and SX ports on the DES-5600 have two modes: auto negotiation 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-5600 and on the link partner to verify settings. See Chapter 4, LEDs, for an explanation of all LEDs. The port settings on the DES-5600 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. Troubleshooting 115

Troubleshooting
This troubleshooting section is intended to help you solve the most common
problems on the DES-5600.
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-5600 performs a Power On Self Test (POST)
every time it is powered on. If you are connected to the
DES-5600 through Local Console Management during the
POST you can see the results displayed on your monitor.
The login panel appears after the DES-5600 has completed
the POST.
The POST checks all of the hardware components on the
DES-5600.
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-5600 to the Network, Cable Specifications, for a
diagram showing the proper pin arrangement for Ethernet
and Fast Ethernet.
Port States
TX and SX ports on the DES-5600 have two modes: auto
negotiation 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-5600
and on the link partner to verify settings. See Chapter 4,
LEDs
, for an explanation of all LEDs.
The port settings on the DES-5600 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.
