2. Hardware Description  
The VOL-1081 Mini-switch is a compact switch with 8x 10/100 N-way UTP switch ports  
plus one 100Base-FX fiber port.  
Front Panel  
ÿꢀThe 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.

ÿRJ-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.]  
ÿ100Base-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.  
ÿDIP-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.

Desktop Installation  
ÿSet the Switch on a clean, smooth, level, and sturdy surface with a power outlet  
nearby.  
ÿMake sure there is enough clearance around the Switch to allow attachment of  
cables, power cord and air circulation.  
Attaching Rubber Feet  
ÿMake sure the surface on the bottom of the Switch is grease and dust free.  
ÿRemove adhesive backing from the rubber feet and apply them to each corner on  
the bottom of the Switch, to minimize shock and vibration.  
Power On  
ÿConnect the power cord to the power socket on the rear panel of the Switch.  
ÿConnect the power cord to any power outlet in the range 100-240 V, 50~60Hz.  
ÿCheck that the power indicator on the front panel is on.

3. Network Application  
This section provides an example of network topology in which the Switch is used. In  
general, the VOL-1081 Mini-switch is designed to be used as a desktop or segment switch.  
You can use the VOL-1081 Mini-switch to connect PCs, workstations, and servers to each  
other by connecting these devices directly to the Switch. The Switch automatically learns  
node address, which are subsequently used to filter and forward all traffic based on the  
destination address.  
Desktop Application  
The VOL-1081 Mini-switch is designed to be a desktop switch, which is ideal for small  
workgroups. The Switch can be used as a standalone switch to which personal computers,  
servers, or printer servers are directly connected to form a workgroup.

4. Trouble Shooting  
This troubleshooting section is intended to help you solve the most common problems on  
the VOL-1081 Fiber Switch. The Switch can be easily monitored through panel indicators  
to assist in identifying problems. This section describes common problems you may  
encounter and where you can find possible solutions.  
Diagnosing with the LED Indicators  
Link  
If the Lnk / Act indicator does not light up after making a connection check whether the  
network interface (e.g., a network adapter card on the attached device), network cable,  
or switch port is defective. Verify that the switch and attached device are on. Be sure the  
cable is plugged in at both ends. Verify that the proper cable type is used and its length  
does not exceed specified limits.  
Power  
If the Pwr indicator does turn on when the power cord is plugged in, you may have a  
problem with power outlet, or power cord. However, if the Switch powers off after  
running for a while check for loose power connections, power losses or surges at power  
outlet.  
Transmission Mode  
The VOL-1081 RJ-45 ports use auto-negotiation to set the transmission mode (i.e., half  
or full duplex). Verify that each attached device is configured to use auto-negotiation to  
set the transmission mode. If auto-negotiation fails the switch will default to half duplex.  
This means no connection will occur if the device attached to the RJ-45 port is set to full  
duplex mode.  
The fiber port requires a manual setting of the transmission mode by means of the DIP  
switch. This means the device attached to the fiber port must be similarly configured  
(i.e., half or full duplex). Remember to cycle the power on the VOL-1081 after the DIP  
switch is changed.  
Cabling  
ÿRJ-45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for  
RJ-45 connections: 100 Category 3, 4 or 5 cable for 10Mbps connections or 100  
Category 5 cable for 100Mbps connections. Also be sure that the length of any twisted-  
pair connection does not exceed 100 meters (328 feet).  
ÿ100Base-FX fiber port: Fiber port can use 50, or 62.5um multi-mode fiber cable to  
connect devices over a 2-kilometer distance.
