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
Serial port 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
Notes: The settings given below are for Adder power switches model numbers PSU-8SLAVE and
PSU-1GUARD - 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, ON or Reboot) 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
r
is for Reboot, 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
Configuration 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, Power Off and Reboot fields
7 Click OK to close the dialog and then click the Save button in the main Host
Configuration window to store the details.
