To connect and address the switch boxes
Note: The AdderView Matrix 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
computers that they will control and not too distant from the AdderView
Matrix (preferably within 2.5 metres).
2 Use a serial cable with an RJ9 and a 9-pin D-type connector (see Appendix
3 for specication). Connect the RJ9 plug to the socket marked ‘IN’ on the
rst switch box. Connect the other end to the socket marked ‘COM’ on the
AdderView Matrix.

1 Off Off
2 On Off
3 Off On
4 On On
Off = switch upwards
On = switch downwards
Switch 1 is on the left side
3 For each of the remaining switch boxes (if used), use a serial cable with RJ9
connectors at both ends (see Appendix 3 for specication). Connect one
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 small switches marked
‘Slct’ on the front panel. The box connected
directly to the AdderView Matrix is Box 1
and so on down the daisy-chain line to Box
4 at the end.
5 Connect IEC to IEC power leads between
each port and the power input socket
of each computer that requires power
switching. Carefully note to which power
ports, on which boxes, each computer 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 conguration stage covered in the Power switching
conguration section within the Conguration chapter.
Power switching connections
A key feature of the AdderView Matrix is its ability to remotely control the
power of the computers attached to it. The actual power switching process
requires the use of optional switch boxes available from a number of suppliers
(Adder part number: PSU-8MASTER and PSU-8SLAVE), however, the AdderView
Matrix offers the control port for these switches and the necessary operational
integration within its menu system.
The control connector of the rst power switch is connected, via serial cable,
to the rear panel of the AdderView Matrix. Any additional power switches are
then connected via a ‘daisy-chain’ arrangement to the rst 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.
Each power port can then be connected to the power inputs of each computer
and each power switch box 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, conguring and using power switching requires three main steps:
• Connect and address the switch boxes
ð
• Congure the power strings
• Operate remote power switching
