Power switching conguration
Power switch conguration comprises three main steps:
• Congure the serial port to the same settings used by the power switch boxes.
• Congure a power ON string for each power port.
• Congure a power OFF string for each port.
The procedures used to achieve the latter two steps are almost identical. 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. Where
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
associated to switch all of the required ports together as a group.
To congure the power-control serial port
1 Display the Conguration menu. Note: You must be logged-in as the
ADMIN user. The settings given below are for the PSU-8MASTER and
PSU-8SLAVE power switches - other power switches may require different
settings.
2 The ‘Functions’ option should be highlighted, press .
3 Press to display the ‘Advanced Options’ menu.
4 Highlight the ‘Power Control’ option and press . Check that the ‘Power
Control’ option is ‘ENABLED’. If not, highlight it and press to change it.
5 Check that the ‘Baud Rate’ entry shows ‘9600’. If not, highlight it and press
to change it.
6 Check that the ‘Format’ entry shows ‘NONE.8.1’. If not, highlight it and
press to change it.
7 Press to quit the screen and save the settings.
To congure the power strings for each computer
1 Switch to the computer port whose power port(s) need to be set.
2 Display the Conguration menu. Note: You must be logged-in as ADMIN user.
3 The ‘Functions’ option should be highlighted, press .
4 Highlight ‘Power Control’ and press .
5 Highlight ‘Edit Power ON String’ and press .
6 Edit the power switch string according to the guidelines given overleaf in the
Editing power strings section. If the current computer port requires more
than one power port, press to begin editing the next string for the next
associated port. Up to four ports may be grouped in this way.
7 Press to save and exit.
8 Repeat steps 5 to 7 for the corresponding ‘Edit Power OFF String’.
