Setting Up Power Control

ELAN status LEDs — These three LEDs show the status of the Ethernet connection as follows:

•100 — When lit, indicates a 100 Mbps connection speed. Otherwise, the connection speed is 10 Mbps.

•Link — Indicates that the interface has an active network connection.

•Act — (Activity) Blinks while data is being sent or received.

FPower LEDs (red) — (One for each receptacle) Indicate that power is being supplied to the attached device.

GPower 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 — Indicates that power is at or above the Full reference threshold.

•S — 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 PCS4 can be set up and operated by using:

•The front panel controls

•A computer or other device using an Ethernet connection and IP protocol (Telnet or a web browser)

The following system setup procedures can be performed using the front panel, the embedded web pages, or the SIS commands. Some settings can be adjusted only through a host computer, either using SIS commands via Telnet or using the PCS4 embedded web pages. For details on setup and control via Ethernet, see the “SIS Programming and Control” or the “HTML Configuration and Control” section.

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	1

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 status defaults to None if all thresholds are cleared (see “None and Not Set thresholds,” later in this section, for more information).
