Power Management (threshold) LEDs
— (Set of two for each receptacle)
After the power thresholds have been set, these LEDs indicate the status of
the attached device as follows:
F (green)
— Indicates that power is at or above the Full reference
threshold.
S (yellow)
— Indicates that power is at or above the Standby reference
threshold, and below the Full threshold.
Setting Up the System Using the Front Panel
The following system setup procedures can be performed using the front panel,
the embedded Web pages, or the SIS commands.
This section discusses the front panel procedures. For information on using the
Web to set up, see chapter 4. For the equivalent SIS commands, see chapter 5.
Setting up power control
To set up control of power to the devices plugged into the
PCS4 receptacles, do the following for each device:
1
.
On the PCS4 front panel, press and release the
power control button for the receptacle into which
the device is plugged.
The red Power LED at the right of the button lights
and remains lit while the receptacle is powered on.
It is unlit when the receptacle is powered off.
2
.
Power on the device, using its own power switch.
Setting power level reference thresholds
You can set the PCS4 to notify you when the power level of a connected device
drops from Full to Standby or to None. For each device, you can use front panel
controls to set the reference threshold (Full or Standby) at which a notification is
triggered.
Until a threshold is set for a receptacle the first time, the status displayed for the
receptacle on the Web page or given in response to SIS
™
queries is Not Set. Once
a threshold has been set, the receptacle’s status defaults to None if all thresholds
are cleared. (See
None threshold
, later in this chapter, for further information.)
There are two common types of power for electronic devices:
soft
and
hard
.
•
Soft power
devices normally have three power states: On, Standby, and
Off. Such devices include projectors, DVD players, and VCRs.
Example:
On soft power devices, the Standby mode allows the unit to be
powered to its Full power mode via RS-232 commands or a remote.
Pressing a PCS4 receptacle button to Off when the receptacle is connected
to a device that supports Standby power causes the device to power off.
•
Hard power
devices normally have two power states: on and off. These
devices include Extron switchers and interfaces.
Example:
On Extron switchers, there is no power button or Standby
condition, and the unit’s power can be set only to On and Off from the
PCS4 front panel. Therefore, when the power is on, it is at Full power, and
can be set for Full reference threshold.
