Power control port
The.AdderView.CATx.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.AdderView.CATx.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 AdderView CATx 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.
AdderView.CATx.IP.unit.(preferably.within.2.5.metres).
2. Use.a.serial.cable.with.an.RJ9.and.a.9-pin.D-type.connector.(see. Appendix
7 .for.specification)..Attach.the.RJ9.plug.to.the.socket.marked. IN .on.the.first.
switch.box..Attach.the.other.end.to.the.socket.marked. POWER CONTROL .on.

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. 
•. Configure the power strings
•. Operate.power.switching. via configuration menu .or. via viewer
3. For.each.of.the.remaining.switch.boxes.(if.used),.use.a.serial.cable.with.RJ9.
connectors.at.both.ends.(see. Appendix 7 .for.specification)..Attach.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.micro.switches.marked.
‘Slct’.on.the.front.panel..The.box.connected.
directly.to.the.AdderView.CATx.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. Power switching
configuration .section.within.the.Configuration.chapter.
