Power switching configuration

Power switch configuration comprises two main steps:

•Configure the COM2 serial port to the same speed as used by the power switch box(es) - see Serial port configuration for details.

•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.

2Click the ‘Configure’ button in the top right corner.

3Click the ‘Host configuration’ option.

4Click a host entry (only numbers are displayed when no entries are configured) within the list to display a Host configuration dialog:

5If necessary, configure other parameters (Name, Users, Hot Keys - MORE).

6Enter the Power control sequences in the Power On and Power Off fields 

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 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 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
