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) via 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 Select the on-screen menu in one of two ways:
• By simultaneously pressing and then releasing
, or
• By pressing the middle and right buttons of a three button mouse.
Note: The mouse switching option is usable only if the ‘Mouse
Switching’ option is enabled. See
Global preferences
for more details.
If the login screen is displayed, enter a valid password.
2 Press to select ‘More menus’.
3 Highlight the ‘Functions’ option and press
to select.
4 Highlight the ‘Power Control’ option and press
to select.
5 As appropriate, highlight either the ‘Edit Power ON String’ or the ‘Edit Power
OFF String’ options to display a screen similar to the one shown below:
Power control sequences
Note: Other power switches may require different settings to those shown
below. 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 (via
configuration menu)
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
Power String [ASCII]
Edit Power ON String
1
P12=1\0D
Power String [HEX]
50 31 32 3D 31 5C 30 44
Strings apply to
Computer : Computer 8
Port : 08
Enter-Save
Esc-Quit
F2-Next String
F1-ASCII/Hex Toggle
6 Enter the required codes either within the upper ASCII section or the middle
HEX section (use to change between them). The required codes are
explained in ‘
Power control sequences’
opposite.

to store the details and exit from the screen.
