Mounting the RUC 
There is nothing special needed to mount the RUC unit.  It will sit nicely on any 
flat surface. Do not allow the unit to dangle in the air on one of the connecting 
cords, as this can lead to fatigue not only on the cord, but to the onboard 
connectors. 
Plug the included power supply into an available power outlet, then plug the 
circular jack on the end of the power cord into the PWR jack on the RUC. After 
a second or two, you will see the LED closest to S1 on the unit start to flash in a 
constant pattern of a second on, then a second off, a second on, then a second 
off, etc. 
Note on the Power Supply: 
It is important that the user use the provided power supply with the unit. This 
power supply provides the correct voltage and current for the unit, plus has the 
right matching plug. In addition, this is the power supply that was used when 
the RUC passed the appropriate FCC EMI testing. 
Specs on the included power supply: 
Input      100 VAC to 240 VAC 
Output       5VDC, 1A 
Output connector    2.1x5.5mm connector 
IMPORTANT: If you do not use the recommended power supply, you must 
ensure that the output voltage of the power supply does not exceed 5.5VDC. If 
this voltage is exceeded, it could cause damage to the unit. Damage caused by 
applying a voltage higher than 5.5VDC is not covered under the Warranty. 
Setting up the LAN 
Standard Ethernet LANs can be built to provide 10, 100 or 1000 megabit per 
second (Mb/s) data rates. The RUC supports 10 Base-T (10 Mb/s) and 100 
Base-T (100 Mb/s) networks over cable of Category 5 (CAT 5) or better. You 
need to decide the data rate you want your LAN to support.  Your decision will 
influence the type of Ethernet network adapters and Ethernet switches you will 
need to purchase or install.  100 Base-T installations will be slightly more 
expensive than 10 Base-T. Nowadays you can purchase reasonably priced 
10/100 Base-T adapters and switches that support both speeds.  
Connecting the RUC to an Ethernet Switch 
Obtain a patch cable long enough to reach from your RUC to the Ethernet 
switch. Connect one end of the cable to the jack labeled “LAN” on your RUC. 
Connect the other end of the cable to any numbered jack on your Ethernet 
switch. You should see the Link Connect LED on your switch go solid indicating 
a good connection.
