KVM Switch

The MC5-IP models provide a serial port 
for connection to one or more optional 
power control units. This allows you to 
control the mains power being supplied 
to the connected computer(s) so that 
an authorised user can, if necessary, 
perform a complete remote cold reboot 
on a failed system.
The control connector of the first power switch is attached, via serial cable, to 
the rear panel of the MC5-IP. Any additional power switches are then attached 
via a ‘daisy-chain’ arrangement to the first power switch. Each power switch box 
is then given a unique address and access to each power port (8 ports on each 
power switch box) is gained using a combination of the switch box address and 
the port number. 

To connect and address the switch boxes
Note: The MC5-IP unit can be powered on during this procedure, however, the 
switch boxes should be switched off.

1  Mount up to four switch boxes in positions where they are close to the 

computer systems that they will control and not too distant from the MC5-IP 
unit (preferably within 2.5 metres).

2  Use a serial cable with an RJ9 and a 9-pin D-type connector (see 

IN

 on the first 

switch box. Attach the other end to the socket marked 

POWER CONTROL

 on 

the MC5-IP.

The power ports are connected to the power inputs of each computer system 
and the power switch box(es) are then connected to a mains power supply.
IMPORTANT: Power switching devices have a maximum current rating. It is 
essential to ensure that the total current drawn by the equipment connected 
to the power switching device does not exceed the current rating of the power 
switching device. You must also ensure that the current drawn from any mains 
socket does not exceed the current rating of the mains socket.
Setting up, configuring and using power switching requires three main steps:

•  Connect and address the switch boxes 

ð

•  

•  Operate power switching 

 or 

3  For each of the remaining switch boxes (if used), use a serial cable with RJ9 

end to the socket marked 

OUT

 of the previous box and the other end to the 

socket marked 

IN

 of the next box. 

4  Set the addressing switches on each switch 

box using the two micro switches marked 
‘Slct’ on the front panel. The box connected 
directly to the MC5-IP is Box 1 and so on, 
down the daisy-chain line to Box 4 at the 
end.

5  Attach IEC to IEC power leads between 

each port and the power input socket of 
each computer system that requires power 
switching. Carefully note to which power 
ports, on which boxes, each computer system is connected. If computer 
systems have multiple power inputs, then each input must be connected via 
separate ports, which can be on the same, or different boxes.

6  Connect each box to a suitable mains power input. 

Now proceed to the configuration stage covered in the 

 section within the Configuration chapter.
