Module Status Field Values
Display Description
Normal The port is working correctly
No Rspns The interface cannot communicate with the port
OnS Fail The port was instructed to be on, but it is off
Off Fail The port was instructed to be off, but it is on
Minimum-On Time field
The editable Minimum-On Time field indicates the minimum amount of time
that a port will stay on before it can be turned off by a command. The default
value is Ø. Manual commands in the control screen’s On and Off fields are
always immediate and ignore this value.
Minimum-Off Time field
The editable Minimum-Off Time field indicates the minimum amount of
time that a port will stay off before it can be turned on by a command. The
default is Ø. Manual commands in the control screen’s On or Off fields are
always immediate, ignoring this value except during a reboot. During a reboot,
whether initiated from the command line or the control screen, the value in
this field determines the time that a port remains in the off state during the
reboot cycle, if it is longer than 15 seconds.
You may use this value to stagger the startup of ports when a command
is issued to reboot multiple ports at the same time. For example, setting
different minimum-off time values may be useful when you issue a Reboot All
command or a Reboot command for a large group.
NOTE: The wake-up power sequencing feature applies only when the entire SPC unit receives
power, not when the power state is changed from the command line or the control screen.
It may be important in your configuration to set the minimum-off time values
differently to avoid a circuit overload caused by an excessive in-rush of current
that may occur when too many devices power up simultaneously.
The following example shows one way to configure the minimum-off time
values for the four ports on each control screen page:
Minimum-Off Time: 00:00:15 00:00:30 00:00:45 00:01:00
