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
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.

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.
