Power switching configuration
Power.switch.configuration.comprises.two.main.steps:
•. Configure.the.OPTIONS.serial.port.to.the.same.speed.as.used.by.the.power.
switch.box(es),.using.the.configuration menu..
•. Configure.power.ON.and.OFF.strings.for.each.relevant.host.computer.
For.each.power.port.there.needs.to.be.a.valid.‘Power.ON.string’.and.similarly.an.
appropriate.‘Power.OFF.string’..In.each.case,.the.strings.are.a.short.sequence.of.
characters.that.combine.a.port.address.and.a.power.on.or.off.value..
If.a.particular.computer.has.more.than.one.power.input.(and.thus.requires.an.
equivalent.number.of.power.ports.to.control.them),.collections.of.strings.can.be.
combined.to.switch.all.of.the.required.ports.together.as.a.group.
To configure the power sequences for each host computer
1. Using.VNC.viewer.or.a.browser,.log.on.as.the.‘admin’.user.
2. Click.the.‘Configure’.button.in.the.top.right.corner.
3. Click.the.‘Host.configuration’.option.
4. Click.a.host.entry.to.display.a.Host.configuration.dialog:
5. If.necessary,.configure.other.parameters.(Name,.Users,.Hot.Keys.-.MORE).

Power control sequences

Note: The settings given below are for the EPS-S8 power switch - other power
switches may require different settings. Please refer to your power switch
documentation for details about codes required by other power switches.
The.structure.of.each.power.sequence.(OFF.and.ON).is.as.follows:
Pxy=z\0D.
Where:.
x.is.the.switch.box.number,
y.is.the.power.port.number,..
z.is.‘0’.for.OFF.or.‘1’.for.ON,.and
\0D.represents.Enter.(or.Carriage.return).
Example 1
To.switch.ON.port.5.of.switch.box.2,.the.code.would.be.as.follows:
•. Power.sequence:.. P25=1\0D
Example 2
To.switch.OFF.port.8.of.switch.box.3,.the.code.would.be.as.follows:
•. Power.sequence:.. P38=0\0D
For.details.about.operating.this.feature,.see.Power switching control.within.
the.Operation.chapter.
To control two or more ports simultaneously
You.can.control.up.to.four.power.ports.using.a.single.sequence..This.is.done.
using.the.same.command.structure.as.shown.above,.plus.a.delay.command,.
for.each.port..Immediately.following.a.port.command,.insert.the.characters.
‘\*’.before.the.next.port.command,.and.so.on.up.to.four.ports..For.instance,.to.
switch.on.ports.1.and.2.in.the.first.power.switch,.the.command.line.would.be:
. P11=1\0D\*P12=1\0D
6. Enter.the.Power control sequences.in.the.Power.On.and.Power.Off.fields.
7. Click.OK.to.close.the.dialog.and.then.click.the.Save.button.in.the.main.Host.
Configuration.window.to.store.the.details.
