The ServSwitch CX with 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 server(s) so that an 
authorised user can, if necessary, 
perform a complete remote cold reboot 
on a failed server.
The control connector of the first power switch is attached, via serial cable, to 
the rear panel of the ServSwitch CX with 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 ServSwitch CX with 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 

server systems that they will control and not too distant from the ServSwitch 
CX with 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 ServSwitch CX with IP.

The power ports are connected to the power inputs of each server 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 



• 

•  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 ServSwitch CX with 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 server system that requires power 
switching. Carefully note to which power 
ports, on which boxes, each server system is connected. If server 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.
