Front Panel
ÿ The Front Panel of the VOL-1081 Mini-switch consists of 8x 10/100 N-way UTP switch
ports (automatic MDI/MDIX), one 100Base-FX fiber port and one Dip-switch to select
fiber port full-duplex or half-duplex mode. The LED indicators are also located on the
front panel of the switch.

ÿ RJ-45 Ports (Auto MDI/MDIX): Eight 10/100 N-way auto-sensing for 10Base-T or
100Base-TX connections.
ÿ [In general, MDI means connecting to another Hub or Switch while MDIX means
connecting to a workstation or PC. Therefore, Auto MDI/MDIX means that you can
connect to another Switch or workstation without changing straight through or
crossover cabling.]
ÿ 100Base-FX Fiber Port: One VF-45™ fiber connector is available for the VOL-1081
Mini-switch as shown above. The distance for fiber cabling can be extended up to 2
kilometers using full duplex.
ÿ DIP-switch: the DIP-switch selects Full-duplex or Half-duplex mode for fiber port.
Generally Full-duplex is used. When the switch is changed, power must be cycled to
read the switch.
