Power switching configuration
Power switch configuration comprises two main steps:
•Configure the POWER CONTROL serial port to the same speed as used by the power switch box(es), either via configuration menu or via configuration page.
•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
1Using 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:
5If necessary, configure other parameters (Name, Users, Hot Keys - MORE).
6 Enter the Power control sequences in the Power On and Power Off fields ð
7Click OK to close the dialog and then click the Save button in the main Host Configuration window to store the details.
Power control sequences
Note: The settings given below are for the
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 (via configuration menu) or Power switching (via viewer) 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
