Connecting the DES-5016 to the Network

Ports
MDI-X Ports
The ports in the 8-Port 10/100-TX module are MDI-X 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-5016 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-5016 has two full sized modules with eight ports each and one half size optional
module.
Fiber Optic Ports
The DES-5016 supports 100BASE-FX and 1000BASE-SX. The chassis supports a
maximum of 18 100BASE-FX ports. The 100BASE-FX 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 sales at D-Link, Inc. to
purchase either of the optional modules.
Refer to Installing Optional Modules, for installation instructions. Refer to Cable
Specifications, for information on cable types and connectors.
Follow these steps to connect cables to the DES-5016:
Check for the appropriate cable configuration for each device.
1. Plug one end of the cable into any of the 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.
RS-232 Port
Follow these steps to connect the DES-5016 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-5016.
