collisions encountered by the corresponding port. When collisions reach a level marked on the front panel display, the corresponding LED lights up. For example, if packet collision reaches 1%, the LED labeled 1% will light up. However, if collisions go beyond 30%, the LED labeled 30+% and all the other LEDs before it (i.e., 1, 5, 10 and 20) also light up in rapid succession.

Note: If either port displays a high collision rate, check to see if any of the connected devices are malfunctioning or if a loop has been formed in your network connections. Otherwise, you may need to reconfigure your network to balance the traffic load.

Setting the Communication Mode (Full/Half Duplex)

Color:

Green

Active LEDs: Full/Half (Display Mode LED)

 

Full (Port Status LED)

Function:

The communication mode can be set to either full-duplex or half-

 

duplex operation. Use the Configure button to light the Full/Half

 

Display Mode LED, indicating that the transmission mode may now

be set for the ports. Next set the Port Status LED for the correspond- ing port in the LED column labeled Full as indicated below.

Indication

Port is set for full-duplex operation.

Port is set for half-duplex operation.

Notes: 1. Full-duplex mode is supported for both ports.

2.Full-duplex operation only applies to point-to-point access (e.g., when attaching the SwitcHub to a workstation, server, or another switch). Repeater hubs use a common collision domain for all communications, and therefore cannot support full-duplex mode. When connecting the SwitcHub to a repeater hub, use a standard cascaded connection set for half-duplex communications.
