Introduction

Congratulations on your purchase of Remote Power On/Off. Built with pride in the United States of America it allows an unmanned PC and/or peripheral devices to be safely powered on/off or rebooted from distant locations, thus eliminating the expense of running a host PC 24 hours-a-day, or minimizing down-time due to remote system or equipment lockups.

Remote Power On/Off consists of the Power On/Off +Aux control unit, cables, and the Intelligent Power Module (IPM). The control unit transparently and passively monitors a standard analog telephone line and responds to Ring, Off-Hook, and On-Hook conditions by sending power-ON, power-OFF, or modem, is ideal for use with host remote control and communications applications like pcANYWHERE, HyperAccess, and others, and is a powerful tool for automatic rebooting of target dial-up systems that fail to answer calls. It completes the setup by introducing Remote Power Control and can be used successfully with any computer or device capable of booting and operating upon power switching on.

REBOOT signals to the IPM. Remote Power On/Off can be used with or without an internal or external

In addition to Remote Power Control, the ShutDown/

REBOOT versions of Remote Power On/Off include the ability to attempt an orderly

shut down of either Microsoft Windows 95/98/ME or Windows NT/XP/2000. The Windows 95/98/ME version includes Server Technology's own AutoShutDown program which monitors either a serial port or a parallel port for notification from the Power On/Off +Aux unit to initiate a shut down prior to a power-OFF or a Service - which monitors a serial port for notification from the Power On/Off +Aux to shut down. The ShutDown/

REBOOT. The Windows NT/XP/2000 version utilizes Microsoft's own UPS

REBOOT versions will

automatically signal your computer to gracefully shut down so that "You can now safely turn off your computer" remotely.

Either version of Remote Power On/Off allows you to choose between three distinct operating modes. The Power-ON Mode allows a device to be powered-ON by an incoming call, remain ON for the duration of the call, then automatically power-OFF after the call is complete. This mode is ideal for traveling laptop users, support personnel, telecommuters, or anyone wishing to remotely operate or access a distant PC or network - from anywhere, anytime - without having to leave the PC running, and without worry if it locks-up. The

REBOOT Mode is ideal for resetting (cold rebooting) any device that is normally powered on. Error or lock-up conditions can be cleared

with a phone call. Safeguards for high traffic systems make the

REBOOT mode ideal for use with fax servers, dial-up access servers, and

more. The Infinite-On/Off Mode is for users that prefer direct switch-on/stay-on or switch-off/stay-off power control.

The +Aux feature of the Power On/Off control unit allows a single telephone line to be shared between a modem, the Power On/Off +Aux, and one other telephone-line device (such as a facsimile or answering machine). This feature eliminates the need for a dedicated modem line while also providing a unique level of security. With the +Aux Feature enabled, routine incoming calls are routed to the Auxiliary device while modem access and power control are safely disguised. Only a specific 'secret' two-call method will enable power control features and grant access to the modem.

It is Server Technology's intent that this product support your remote computing needs. Every attempt has been made, through design and craftsmanship, to ensure quality and compatibility. We believe it will become an integral and truly valuable part of you're remote computing setup and guarantee correct operation in accordance with this manual with a 1-year repair or replacement warranty.

About this Guide

This guide is intended to be printed. Printing this guide will provide proper clarity of the diagrams.

Remote Power On/Off has been designed to control power supplied to a PC. In general, the PC is running a communications application that utilizes an analog modem to communicate over ordinary telephone lines. Although the manual is written with this in mind, the Remote Power On/Off is capable of controlling power to any device that can be turned on and off by its AC source. As long as the device powers on simply by providing power to it, the Remote Power On/Off can turn on, turn off, or reboot the device with a phone call; a modem is not required. Refer to the following on-line document for guidelines and useful information if you are unsure about whether or not your particular computer is capable of being turned on and off by the AC power source:

http://www.servertech.com/library/Technote/atxpowerrestart.PDF

The primary installation section of this manual describes the installation of the standard Power On/Off +Aux, model #PP02. These instructions generically apply to all versions. Additional #PP03, and the Windows NT/XP/2000 ShutDown/ Appendix B and Windows NT/XP/2000 ShutDown Appendix C respectively.

This fourth edition manual was created for electronic distribution only; it has never been published in printed form. Information contained in this manual is not necessarily accurate for all existing Power On/Off +Aux revisions. Server Technology's original Remote Power On/Off was introduced in 1990 and the "+Aux" version was introduced in early 1993. Server Technology only warrants that your Power On/Off +Aux product will operate according to the manual that was originally delivered with the product. In general, if the product was purchased in 1997 or later, then this manual will accurately reflect your fully-operational unit's behavior.

Installation should be performed only after printing and reading this manual in its entirety and with the unit configured to factory defaults as originally received. Once the installation is complete you must determine which operating mode (either the Power-ON, Infinite-On/Off) you would like to use, then proceed to that section of this manual for specific instructions. For additional information about the +Aux feature for line-sharing or as a security measure, refer to the +Aux Feature section; this section explains Power On/Off +Aux's unique line-sharing feature, which is useful for allowing a single phone-line to be used for a modem, the Power On/Off +Aux, and one other automatic answering telephone device.

Please note that Power On/Off +Aux is designed and built to monitor a single telephone line. In America, a single line is generally wired as the two center conductors/pins within a common RJ11 phone jack. Although Power On/Off +Aux is a single-line device, it does complete un-monitored passing of a second line through its RJ11 telephone connectors. In addition, the primary line that is monitored is surge-protected by a single metallic-oxide varistor (the main component in surge-protection) and two fuse-resistors (one for the modem and a second for the auxiliary device). Although relatively rare, damage to the Power On/Off +Aux unit due to surge is not covered under the product's warranty, and liability for damage to other equipment due to surge on the telephone line is herein expressly denied.

A sample session, Power-ON Mode:

1 The user makes a modem call to the phone number of the line attached to the Power On/Off +Aux control unit.

2 The Power On/Off +Aux unit detects the incoming RINGs and counts them. After the first ring, the Power On/Off

+Aux signals the IPM to power-ON the host PC and peripherals.

3 The line continues to ring as the PC is booting. A command in the PC's AUTOEXEC.BAT or Startup folder loads

the host/communications software (i.e. pcANYWHERE, HyperAccess, etc.), or the host program loads per its own "launch at startup" option (through modification of the registry). The modem is initialized into answer mode.

4 The modem answers the incoming call and a connection is made. The Power On/Off +Aux sees the OFF-HOOK

condition present on the line, indicating that the line is in-use, and keeps the power ON for the duration of the call.

5 When the user is finished and ends the session, the modems disconnect (hang-up) and the ON-HOOK condition is

detected. The IPM is signaled to power-OFF.

This scenario describes a remote session using the Remote Power On/Off according to its factory default settings. There are many interesting options to supplement using the system in other ways. See the Sample Session section for more examples.

Installation

This section covers the initial installation and testing of the Power On/Off +Aux control unit and the Intelligent Power Module (110vAC version). For additional installation information regarding the Windows 95/98/ME and Windows NT/2000/XP ShutDown/ versions refer to Appendix B and Appendix C respectively. For the 220VAC IPM, refer to page 39 of Appendix A.

Default Settings

Installation should be performed with the factory default DIP-switch configuration as shown below. Switch numbers 2 and 5 are ON (down):

1 2 3 4 5 6 7 8

Install the Intelligent Power Module (IPM)

Toggle the IPM 0|1 switch to the INPUT (0) position. Plug the IPM in-line between a live AC outlet and a multiple outlet surge strip. Next, plug the PC and associated peripherals' power cables into the outlet strip. The power switch on the PC and peripherals must be set and remain in the ON position. Toggle the IPM switch to the ON (1) position and the PC and associated devices should power ON. Toggle the IPM switch back to the INPUT (0) position and the PC and

associated devices should power OFF.

The switch should remain in the INPUT (0) position.

REBOOT

NOTE: For systems with an Uninterruptible Power Supply (UPS; a battery back-up), the UPS plugs into the live AC outlet and the IPM plugs into an outlet provided by the UPS. The switch on the UPS must always remain on.

Insert one end of either included telephone cable into the IPM's port labeled "Input". This is now the IPM Signal Cable.

For an example of what the system should look like once installed, see the Before and After diagrams on pages 13 and 14.

Install the Power On/Off +Aux Control Unit

Position the Power On/Off +Aux Control Unit in a suitable spot near the PC. The Master "ON/OFF" switch is located on the face of this unit, so choose a location on the desktop that is easily accessible. Next, plug the wall-mount power supply into another live AC outlet (not controlled by the IPM) and insert the plug into the jack labeled "Power" on the rear of the control unit. The "S

TATUS" light should begin to flash.

NOTE: UPS users must attach the wall-mount power supply to a second backed-up outlet provided on the back of the battery back-up. If not, a power outage will result in the PC powering off because the IPM will switch off if the Power On/Off +Aux unit looses power. Do not plug the power supply into an outlet that is switched on/off by the IPM.

Insert the free end of the IPM signal cable into the port labeled "IPM P control the IPM. Press the switch once - the LED should illuminate, the IPM should activate, and the PC and peripheral devices should power-ON. Press the switch again - the devices should power-OFF. This is now the Master switch for turning the PC on and off.

Operating Modes and Options

Remote Power On/Off offers three exclusive Operating Modes with several selectable options for each mode. Operating modes and options are determined by the Power On/Off +Aux control unit's DIP-switch settings.

The two common Operating Modes are the Power-ON Mode (next page) and the modes, their individual options, and the DIP-switch settings, are discussed in the following sections. Discussion of the third mode, the Infinite-On/Off Mode, begins on page 26.

Safeguards:

The Power On/Off +Aux control unit is programmed with several safeguards which apply automatically to each operating mode. It is important to note each as they may cause time-related functions to appear incorrect.

Wake-up Delay - Whenever power is first supplied to the Power On/Off +Aux control unit there will be a 30 second delay before any power-ON signal is sent to the IPM. This delay can help protect the devices attached to the IPM from power surges and transient spikes that occur during brownouts or following a blackout.

Minimum ON Time - In all cases where the power is automatically turned-ON by a function of the Power On/Off +Aux unit, it will remain ON for a minimum of one (1) minute for a PP02, 90 seconds for a PP03, and five (5) minutes for a PPNT. This design is to ensure a complete POST (Power On Self Test), RAM check, and complete boot whenever the PC is powered-ON.

Minimum OFF Time - Anytime the power is turned-OFF by an automatic function of the Power On/Off +Aux unit, it will remain OFF for a minimum of 30 seconds. This design is to ensure a complete "settle" whenever the PC is poweredOFF.

REBOOT Mode (begins page 20). These operating

REBOOT Inhibit Time - This timer inhibits incoming calls from initiating a reboot for 2

first supplied, the IPM is instructed to turn on, or following a prior

REBOOT. This guarantees the host or server system is

/2 minutes whenever power is

always allowed to fully boot and be ready to answer incoming calls before subsequent reboots are allowed; perpetual reboots due to incoming calls that cannot be answered - because the system is still booting - are avoided. This safeguard, designed for high-traffic systems such as fax servers, applies only to the

REBOOT Operating Mode. After supplying

power to the Power On/Off +Aux unit for the first time, be sure to wait about three minutes before testing.

Remote Power On/Off Operating Modes • 15

Power-ON Mode

The default operating mode for the Remote Power On/Off system is the Power-ON Mode. This mode allows a PC and peripherals to be turned-ON by an incoming telephone call and automatically turned-OFF after the call is completed.

In this mode, the Power On/Off +Aux control unit monitors the telephone line for three conditions known generically as RING, OFFHOOK, and ON-HOOK. The system will react as follows:

RING: When a call is placed to the unit, each incoming RING is counted and, after a selected ring number, the power ON signal is sent to the IPM.

OFF-HOOK: The power-ON signal to the IPM will endure as long as RING(s) continue or OFF-HOOK exists (the call has been answered).

ON-HOOK: When hang-up occurs, the ON-HOOK condition is detected. After a selected delay, the power-OFF signal is automatically sent to the IPM.

NOTE: When operating the PC locally, the Master ON/OFF switch must be used to power the system both on and off. In such cases, when the PC is powered-ON locally by the push button, incoming calls will never alter the ON state unless the 15-Ring Turn-Off option (described later in this section) is enabled.

Power-ON Mode Options

Power-ON Ring Number - This option sets the number of RINGs after which the Power On/Off +Aux control unit

sends the power-ON signal to the IPM. The default is one (1) RING. Optional settings are five (5), or ten (10) RINGs. The five or ten ring options are useful as an added security feature (so that the PC will not power-ON with every call) or to allow voice or non-modem calls to be answered prior to the power turning on.

Power-OFF Delay Time - This option sets the delay time that the control unit will wait, after ON-HOOK (hang-up) is detected, before sending the power-OFF signal to the IPM. The default is to send the power-OFF signal one (1) second after ON-HOOK is detected, so long as the Minimum-On-Time has expired. Optional settings are two (2) minutes, 15 minutes, and one (1) hour.

Remote Power On/Off Power-ON Mode • 16

Note: These Power-OFF Delay Time settings are useful to support post-connection operations, such as host software "Call-Back" services. The recommended selection for this option is two minutes. This will allow time for a re-dial in cases where the first connect fails (usually because the host PC takes too long to fully bootup), as well as plenty of time to re-connect if an accidental or unexpected disconnect occurs during a session.

15 Ring Turn-OFF Option - This option provides the ability to remotely turn-OFF the host PC and peripherals anytime the power was left in a manual-ON state (the power was turned-on locally using the square Master Switch on the front panel). With this feature enabled, an incoming call allowed to ring long enough will effect a Turn-OFF immediately on the fifteenth RING. Subsequent calls can then be used to remotely boot the system up and keep it on for the duration of the call.

This feature is useful if the host PC has been left powered-on without a host/communications software running in a "wait for call mode". By placing a call to the host PC, the unanswered call will cause a power-OFF immediately on the fifteenth ring. Another call can then be used to remotely power the system on to gain access after the host application loads upon startup.

This feature can also be used to Turn-OFF a PC that was intentionally left in a powered-ON state. For example, an office PC intentionally left running in the evening to perform an after-hours back-up can be turned OFF later from home.

DIP Switch Configuration - Power-ON Mode

The following outlines the DIP switch positions for the various functions that apply to the Power-ON operating mode. Each switch is defined as either OFF (up) or ON (down). DIP-switch changes are dynamic - selections become effective immediately (upon the next call) without having to power-cycle the unit. Default selections are marked with an "*".

DIP switches 7 and 8 will be discussed later.

Power-ON Ring Number

DIP switches 1 and 2 are used to select the Power-ON Ring Number:

1|OFF 2|ON Power-ON Ring One (1) *

1|ON 2|OFF Power-ON Ring Five (5)

1|ON 2|ON Power-ON Ring Ten (10)

Remote Power On/Off Power-ON Mode • 17

Power-OFF Delay Time

DIP switches 3 and 4 are used to select the Power-OFF Delay Time value:

3|OFF 4|OFF 1 second Power-OFF Delay Time *

3|OFF 4|ON 2 minute Power-OFF Delay Time

3|ON 4|OFF 15 minute Power-OFF Delay Time

3|ON 4|ON 1 hour Power-OFF Delay Time

DIP switch 5 determines when the Power-OFF Delay Time should apply:

5|OFF Power-OFF Delay Time only applies following hang-up, but only if the call had been answered (Off- hook was detected).

5|ON Power-OFF Delay Time always applies. *

15 Ring Turn-OFF Option

DIP switch 6 enables/disables the 15 Ring Turn-OFF option:

6|OFF 15 Ring Turn-OFF Option Disabled *

6|ON 15 Ring Turn-OFF Option Enabled

Technical Note: Because the telephone company RING signal is not always synchronized between the calling and receiving parties, it is best to allow one extra ring when counting the rings to effect a power-ON or power-OFF. For example, if the Power-ON Ring Number is set to five (5), allowing the line to ring six (6) times should guarantee that the required minimum number of rings have occurred at the target end of the call.

REBOOT Mode

The second operating mode is the REBOOT Mode. This mode is used to remotely reboot a device by temporarily interrupting its power source. The individual PCs, or any distributed device in a lock-up or error state. The power-ON signal to the IPM is constant to keep the devices powered on. When a reboot is executed, the power-OFF signal is sent, a settle time of 30 seconds lapses, then the power-ON signal to the IPM is restored.

NOTE: When operating in this mode the Master Switch will no longer act as a local power on/off switch! Instead, the ON/OFF switch will serve to enable/disable the remote

Preface

The REBOOT Mode provides four possible methods for initiating a remote reboot -- the "No Answer REBOOT", the "On-

REBOOT", the "Aux Port REBOOT", and the "Off-Hook (busy) REBOOT". Each method is described in the

Hook following pages. To apply the appropriate method, it is first important to understand the four possibilities when attempting to connect to a distant dial-up system:

• The call placed to the host PC is answered, the

connection is made, and operation is successful.

With the No Answer REBOOT method, the Power On/Off +Aux control unit will count incoming RINGs and only initiate a reboot when a selected Ring-Count occurs and anytime, either before or after the selected Ring-Count, the reboot is canceled.

The minimum Ring-Count required to initiate a reboot can be set to either one (1) or eight (8). Set to one, any call that is not answered will initiate a reboot when the caller hangs-up (RINGs cease). Set to eight, the caller must allow at least eight RINGs to occur before hanging-up to initiate the reboot.

This method is extremely useful for high-traffic systems, such as a bulletin-board or fax servers, where lock-up/error conditions generally cause incoming calls to go unanswered. Using this method, the lock-up/error condition will clear automatically when the system reboots after a failed connection attempt.

To be covered for ALL types of lock-up/error conditions, it is advisable to configure the host modem to answer on two rings greater than the minimum Ring-Count. If the Ring-Count is set to one (1), the host should be set to answer on ring number three (3). If the Ring-Count is set to eight (8), the host should be set to answer on ring ten (10). In cases where the modem answers but the connection fails or operation is unsuccessful, this will allow a reboot to be forced by redialing and hanging-up after the selected Ring-Count but before the modem answers.

For example, the system will operate as follows (Ring-Count = 1):

With the On-Hook REBOOT method, the Power On/Off +Aux control unit will initiate a reboot upon detecting the ONHOOK condition that occurs upon hang-up with every modem disconnect. Often called the "sledgehammer" method, this is a hardware equivalent to the 'reboot on hang-up' option found in many host/communication programs. This method will initiate a reboot after each and every inbound
