4.3.2 Configure Ports

Figure 6 shows how individual Ethernet ports can be Enabled or Disabled. Also, the

operating data rate or “speed” and duplex can be given a specific setting or be set to

auto-negotiate.

NOTE: Certain models use fibre optic cable on two ports. For these ports, the only Speed/Duplex

option is Full or Half Duplex. The Speed for fibre ports is fixed at 100 Mbps.

A single Ethernet cable will link two devices. When these devices auto-negotiate, the

data rate will be 100 Mbps only if both are capable of that speed. Likewise, full-duplex

will only be selected if both can support it. If only one device supports auto-negotiation,

then it will match the data rate and duplex mode of the non-auto-negotiating device.

Sometimes it is advantageous to select a fixed data rate and duplex setting on both

Ethernet devices to eliminate the auto-negotiation process.

When interconnecting two switches, crossover cables are normally used — but if one

switch uses Auto MDIX, the communication can be via either straight-through cable or

crossover cable. This functionality does not require both switches to have Auto MDIX.

Figure 6 — Configure Ports Menu

NOTE: The sample screen above is the first of two displayed for a 16-port switch — or the first of

three displayed for a 24-port switch. The succeeding screens are accessed by choosing

the Continued option just above the dashed line. This option is not displayed in the

Configure Ports screen of an 8-port switch.
