Ports
MDI-X Ports
MDI-X ports are crossover ports. The pin arrangement is the same as the arrangement in
a crossover cable. The advantage of MDI-X ports is that you can connect a device with
an MDI-II port without using a crossover cable. The steps for connecting the DES-5024
to 10 Mbps devices or 100 Mbps devices are the same. All the ports will auto negotiate
the proper speed and duplex mode. The DES-5024 has two full sized modules with 12
ports each and one half size optional module.
Follow these steps to connect cables to the DES-5024:
Check for the appropriate cable configuration for each device.
1. Plug one end of the cable into any of the MDI-X ports.
2. Plug the other end into the appropriate port on the other device.
3. Verify that the LED indicates connection at the proper speed and duplex mode.
Fiber Optic Ports
The DES-5024 supports 100BASE-FX and 1000BASE-SX. The ports are on modules
that you can install in the chassis. The chassis supports a 2-Port 100BASE-FX optional
module. The ports support full and half duplex at 100 Mbps. The ports do not support 10
Mbps.
A 1-Port 1000BASE-SX optional module is available. The 1-Port 1000BASE-SX
optional module only supports full duplex at 1000 Mbps. Contact D-Link, Inc. sales to
purchase any of the modules.
Refer to Chapter 3, Installing Optional Modules, for installation instructions. Refer to
Chapter 3, Cable Specifications, for information on cable types and connectors.
RS-232 Port
Follow these steps to connect the DES-5024 and another device:
1. Plug one end of the cable provided into the port.
2. Plug the other end into the PC.
3. Run HyperTerminal or a terminal emulation program using the settings given for
Local Console Management at the beginning of Chapter 5, Managing the DES-5024.
