Ports
MDI-X Port
MDI-X ports are crossover ports. The pin arrangement is the same as the arrangement in a crossover cable. The advantage of an MDI-X port is that you can connect a device with an MDI-II port without using a crossover cable. The steps for connecting the DES-3216 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-3216 has one row of 16 MDI-X ports.
Follow these steps to connect cables to the DES-3216:
1.Check for the appropriate cable configuration for each device.
2.Plug one end of the cable into any of the MDI-X ports.
3.Plug the other end into the appropriate port on the other device.
4.Verify that the LED indicates connection at the proper speed and duplex mode.
RS-232 Port
Follow these steps to connect the DES-3216 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-3216.
DES-3216 to DES-3216 Connection
Connect two DES-3216s together one of the MDI-X ports. The DES-3216 is also compatible with the DES-5016 and DES-5024. Port Trunking can be configured on the device if more than one port is connected between two DES-3216s or if more than one port is connected between a DES-3216, DES-3224, DES-5016 and DES-5024. Port trunking increases the efficiency of the DES-3216 by increasing the bandwidth. See the section on Port Trunking in Chapter 5 for instructions on how to configure Trunked ports.
Connecting the DES-3216 to the DES-5024 and Hubs
You can connect the DES-3216 to other switches and hubs on the network. The DES-3216 and the DES-5024 are compatible products that can be connected easily. If you create multiple connections between devices, create Trunked ports for more efficiency. See the section on Port Trunking for more details.
