any Smart-UPS UPS with a card slot or an embedded Network Management Card, any
Smart-UPS DP UPS, any Matrix-UPS UPS with a firmware revision of Y or later,
any Symmetra UPS, and any Silcon Series UPS.
An APC Network Management Card (APC part number AP9617, AP9618 or AP9619)
with a firmware revision of 1.1.0 or later OR an APC Web/SNMP Card (APC part
number AP9606). If you are also using an APC Environmental Monitoring Card
(APC part number AP9612TH), your Network Management Card must have firmware
revision 1.1.5 or greater.
- You can update your APC Network Management Card firmware from the APC Web site.
- PowerChute Network Shutdown cannot be used with APC PowerNet SNMP
  Adapters (cards). If your card has an APC part number of AP9605, AP9205, or
  AP9603, contact APC support or your APC dealer to upgrade the
  card.
- If you are using multiple Smart-UPS devices, multiple Symmetra devices,
  or have a Parallel Silcon UPS system, you use one Network Management Card in
  each UPS in the system. If your Network Management Card has firmware
  revision 1.2.0 or later, be sure that the Synchronization option is
  disabled.
Note: AP9606 is only supported with single Smart-UPS, Matrix,
Symmetra, or Silcon and Parallel Silcon configurations. It is not supported
with either a multiple Smart-UPS or multiple Symmetra configuration.
A supported operating system as listed on the APC Web site.
The IP address for each APC Network Management Card.
A Java Virtual Machine (JVM), version 1.4.2 or later, on your server for
all operating systems except NetWare (see next paragraph). You can download a
Java Virtual Machine from http://java.sun.com/. PCNS installs JVM 1.4.2
if the most recent version found on your system is less than this. If a JVM
version greater than 1.4.2 is found on your system, PCNS will use the later
version.

On Novell NetWare, both JVM 1.4.1 and 1.4.2 are
supported. (NetWare 6 has JVM 1.3.1). Novell JVM 1.4.1 and 1.4.2 are available
on Novell’s Web site.
If you are installing PowerChute Network Shutdown on more than 50

3052 must be open for communication with the Management Card.
You must have Administrator privileges on the network.

Installation

To install and operate the
PowerChute Network Shutdown software, perform the following steps.

Install the Network
Management Card in your UPS. For installation instructions, see the Management
Card Installation and Quick Start Guide that was shipped with your card. If
you are using multiple Smart-UPS devices, multiple Symmetra devices or a
Parallel Silcon UPS, you will use one Network Management Card in each UPS in
the system.

Install the Card in your
UPS and configure it with an IP address before beginning the PowerChute
Network Shutdown software installation. If you install PowerChute Network
Shutdown first, additional
steps will be required when installing the Network Management
Card.
Using the Network
Management Card user interface, configure the UPS and the Network Management
Card. At a minimum, perform these tasks:
- On the Configuration
  page, set the Low-Battery Duration to at least five minutes
- On the User Manager
  page, set the Administrator User Name, Password and Authentication Phrase.
  You must enter the SAME Administrator User Name, Password, and
  Authentication Phrase when you install PowerChute Network Shutdown.
  
  Note: The
  Network Management Card uses the same default User Name, Password and
  Authentication Phrase as PowerChute Network Shutdown.
Remove any existing
version of PowerChute Network Shutdown before starting the installation
program.

WARNING: Do
not install and use PowerChute Network Shutdown on a computer system that uses
PowerChute plus or PowerChute Business Edition.
The installation program must be run on the server console.
To start the PowerChute Network Shutdown installation, choose from the
sections directly below specifying different OS systems and hardware.

For installation on a IA-64 processor machine, follow these
steps:

For
installation on Solaris and Linux, perform the following steps. After you
finish the installation, you can use the Silent
Installation to set up additional servers to have the same PowerChute
Network Shutdown configuration.
1. If you downloaded the file pcns221lnx.bin for Linux or
  pcns221sol.bin for Solaris from the APC Web site, copy the file to a
  temporary directory on the file server.
  
  If the software
  is on a CD, copy the installation file from the CD to a temporary directory
  on the file server.
2. Change your
  working directory to the directory containing the installation file. Change
  the permissions on the file to make it executable. Then type the following
  command:
  
  ./pcns221lnx.bin
  for
  Linux
  
  ./pcns221sol.bin
  for Solaris 8 or
  9

For installation on
NetWare, perform the following steps.

If you downloaded the file pcns221net.exe from the APC Web site,
copy the file to a temporary directory on the SYS: volume of the NetWare
file server; then execute the file to extract the installation files.

If the software is on a CD, copy the installation files
(pcns221net.jar and util.jar) from the NetWare directory on
the CD to a temporary directory on the SYS: volume of your NetWare file
server.
From the server’s System Console command prompt, enter the following
command (where tempdirectory represents the location of the installation
files).

java -cp
SYS:\tempdirectory\pcns221net.jar;SYS:\tempdirectory\util.jar load

At the following

however in the same family and can’t be used in combination with
them.

The IP address of
the PowerChute Network Shutdown computer is registered with the Network
Management Card if a UPS fails to register. You should manually remove it in
this circumstance: Registering
an IP Address with the Network Management Card.
Enter the
initial configuration information:
- Management
  Card IP: This is the network address of the Network Management Card attached
  to your UPS.
  
  If you are
  using multiple Smart-UPS devices, multiple Symmetra devices or a Parallel
  Silcon UPS, enter the IP address of the Network Management Card in the first
  UPS device, select Add, and then continue adding IP addresses for all
  of the cards in this UPS system. (Up to 3 IP addresses for multiple
  Smart-UPS devices and multiple Symmetra devices, and up to 9 IP addresses
  for a Parallel Silcon UPS.)
- The http port
  being used by the Network Management Card. The default is 80. Do not change
  this number unless you changed the http port being used by your Management
  Card. For multiple Smart-UPS devices, multiple Symmetra devices or a
  Parallel Silcon UPS system, all of the Network Management Cards must use the
  SAME http port.
Click Next to
continue.
Enter the
security configuration information:

The default

both PowerChute Network Shutdown and the Network Management Card. If you have
not changed the default settings in the Network Management Card, click
Next; otherwise, enter the same values used by the Network Management
Card and click Next.

The User Name and
Authentication Phrase authenticate the communication between PowerChute
Network Shutdown and the Network Management Card. You use the same User Name
and Password to log on to the user interface of PowerChute Network Shutdown
and the Network Management Card.

If you are using
multiple Smart-UPS devices, multiple Symmetra devices or a Parallel Silcon UPS
system, all of the Network Management Cards in the UPS system must use the
same Administrator User Name and Authentication Phrase.

Note: Any Java exceptions displayed during the
installation will not affect the successful completion of the installation or
operation of PowerChute Network Shutdown.
Complete the
software installation:

PowerChute
Network Shutdown registers with the Network Management Card automatically so
that they can communicate.

If PowerChute
Network Shutdown cannot register with the Management Card, you receive an
error message. You may continue the installation, but you must enter
the server IP address manually at the Network Management Card.

On NetWare, a pop-up message asks whether changes to the
autoexec.ncf file can be made. You should select Yes (otherwise the
service won’t start when the OS starts).

Notes
- If you select Cancel to stop the installation, the jvm
  directory remains under C:\Program Files\jvm (in Windows), and the
  /usr/local/bin/jvm (in Linux). The directory must be deleted manually before
  attempting another installation. You should also delete the PowerChute
  directory.
- The Temp directory might have some sub-directories remaining after the
  installation. You can remove these manually, but they won’t affect your
  computer system or PowerChute Network Shutdown.
Start the
PowerChute Network Shutdown process:

The PowerChute
Network Shutdown service (on Windows 2000, Windows XP and Windows 2003), the
daemon (on Linux and Solaris), or the process (on NetWare) starts
automatically when the installation is completed. You can then delete the
installation files.

Note: After installation, set access on the PowerChute
directory so that only authorized users can access, execute, or remove the
software.
Open the
PowerChute Network Shutdown user interface:

Using a Web
browser, enter either of the following URLs:

http://servername:3052
http://serverIPaddress:3052

For example, if your
server is named COMP1 and has an IP address of 117.14.53.59, use one the
following URLs:

http://COMP1:3052
http://117.14.53.59:3052

If you are using
a browser version other than Microsoft Internet Explorer version 5.5 or 6.0,
some functions may not be available.

Silent
Installation

You can perform a silent
installation on systems with a single UPS only. You must perform a normal
installation on multiple Smart-UPS devices, multiple Symmetra devices or
Parallel Silcon UPS systems.

On Windows 2000, Windows XP,
Windows 2003, Linux and Solaris systems, you can install PowerChute Network
Shutdown from a command line, which allows you to set up many servers that run
the same operating system and that have the same PowerChute Network Shutdown
configuration. To install PowerChute Network Shutdown silently, perform the
following steps:

Complete a normal
installation on one server.
Configure PowerChute
Network Shutdown to have all of the settings that you want.
Copy the m11.cfg
and silentInstall.ini files from the PowerChute directory.
Edit the
silentInstall.ini file to have new parameters, if required. Precede
each path separator (‘\’ for Windows and ‘/’ for Linux and Solaris) with an
escape character (‘\’).
- Edit the applicationDirectory parameter to
  specify the directory in which to install PowerChute Network
  Shutdown.
- Set the RegisterWithAdapter parameter in
  the silentInstall.ini file to “yes” or “no” to indicate whether the
  installation should register this host’s IP address with the Network
  Management Card.
  
  Note: This
  parameter is applicable only if you are installing PowerChute Network
  Shutdown on more than 50 computers for one Network Management Card. See the
  document “PowerChute Network Shutdown with more than 50 computers on One
  UPS,” available from the download page for PowerChute
  Network Shutdown for your operating system on the APC Web
  site.
If you are installing
PowerChute Network Shutdown for a UPS with a different IP address, uncomment
and edit the adapterIPAddress
parameter in the silentInstall.ini file. Enter the IP address of the
Network Management Card that is in the UPS.
Put the m11.cfg
file, the silentInstall.ini file, and the PowerChute Network Shutdown
installation files in a temporary directory on the new server.
Use the commands specified
below on the relevant system. For all systems, if there are spaces in the path
to the temporary directory, enclose the path in quotation marks. For example:

C:\pcinstall\pcns221win.exe -q
“C:\Program Files\InstallDir\silentInstall.ini”
C:\pcinstall\pcns221win.exe
-q C:\InstallDir\silentInstall.ini
- For an installation on
  an IA-64 processor machine:
  
  on a Windows machine
  running Windows Server 2003, Enterprise Edition:
  [#JavaHomeDir]/java -cp
  .;pcns221win64.jar;util.jar load -q
  C:\tmp\pcns22\silentInstall.ini
  
  on a Linux machine
  running Red Hat Enterprise Linux AS:
  [#JavaHomeDir]/java -cp
  .:pcns221lnx64.jar:util.jar load -q
  /tmp/pcns22/silentInstall.ini
- For an installation on
  Windows 2000, Windows XP and Windows 2003, navigate to the temporary
  directory on the new server, and type the following command on one
  line:
  
  C:\tempdir\pcns221win.exe -q
  C:\tempdir\silentInstall.ini
  where tempdir is the
  location of the installation program and of the valid m11.cfg and silentInstall.ini
  files.
- For an installation on Linux or Solaris, navigate to the
  temporary directory on the new server and use the following command:
  
  For Linux: ./pcns221lnx.bin -q
  tempdir/silentInstall.ini
  
  For Solaris:
  ./pcns221sol.bin -q
  tempdir/silentInstall.ini
  
  After you complete the
  installation, check the install.log and errors.log files for
  error conditions.

Registering an IP
Address with the Management
Card

If the installation program
cannot communicate with the Network Management Card, you must manually register
the IP address of the computer on which PowerChute Network Shutdown is
installed. In some cases, the installation program registers the IP address, but
is unable to confirm that it is registered; in such cases, you must check to
ensure that the IP address is registered.

Access the Network
Management Card’s user interface by using the Network Management Card IP
address as the URL.
Click on the UPS model
name displayed on the menu.
Select the
PowerChute menu option to display a list of the IP addresses which are
registered with this Network Management Card.
To add a new IP address,
type the IP address of the server on which PowerChute Network Shutdown is
installed in the Add Client IP Address field, and click Add.

To remove existing IP
addresses, select each address from the Configured Client IP Addresses list,
and click Remove.

Using the PowerChute Network

Running on
SolarisTM

You must have Solaris
version 5.8 or 5.9 (SPARC) to use PowerChute Network Shutdown. XWindows is
required to install PowerChute Network Shutdown.

PowerChute Network Shutdown
requires Java Virtual Machine (JVM), version 1.4.2 or later, on your server.
Obtain this JVM from the Sun Microsystems Web site, or contact your Sun
Microsystems service provider. PCNS installs JVM 1.4.2 if the most recent
version found on your system is less than this. If a JVM version greater than
1.4.2 is found on your system, PCNS will use the later version. It is
recommended that the location of the JVM executable (java.exe) be in the PATH
environment variable prior to installing PowerChute Network Shutdown. The JRE
install path on Solaris is /usr/bin/jvm.

When the daemon starts, the
script adds 256 file handles; delete ulimit -n 256 from the PowerChute
Network Shutdown startup script if you do not need
them.

To stop PowerChute Network
Shutdown, type the following at the command line:

/etc/rc2.d/S99PowerChute
stop

To start PowerChute Network
Shutdown manually, type the following at the command line:

/etc/rc2.d/S99PowerChute
start

To remove PowerChute Network
Shutdown, run the uninstall script. If you do not intend to reinstall the
software, remove the server IP address from the Network Management Card by using
the PowerChute option on the Network Management Card’s Web interface
menu.

The PowerChute directory
sometimes remains after an uninstall. You can remove this manually, but it won’t
affect your computer system or PowerChute Network
Shutdown.

For information on using the
Configuration Utility, see Running
the Configuration Utility on Linux or
Solaris.

Running on
Linux®

XWindows is required to
install PowerChute Network Shutdown.

To run PowerChute Network
Shutdown on Red Hat Linux, you must use version 8.0 or
greater.

PowerChute Network
Shutdown requires Java Virtual Machine (JVM), version 1.4.2 or later, on
your server. Obtain this JVM from http://java.sun.com/, or contact your Linux
vendor or service provider. PCNS installs JVM 1.4.2 if the most recent version
found on your system is less than this. If a JVM version greater than 1.4.2 is
found on your system, PCNS will use the later version. It is recommended that
the location of the JVM executable (java.exe) be in the PATH environment
variable prior to installing PowerChute Network Shutdown. The JRE install path
on Linux is /usr/local/bin/jvm.

Notes for the
SuSE operating system:

On SuSE, the service is installed in /etc/init.d/PowerChute. The default
for all other Linux platforms is /etc/rc.d/init.d/PowerChute.
The installation dialog box first displays on the right of the screen on
SuSE: it has to be moved to the center to proceed.

To stop PowerChute
Network Shutdown, type the following at the command line (see the note above for
SuSE):

/etc/rc.d/init.d/PowerChute
stop

To start PowerChute

For information on using the Configuration Utility, see Running
the Configuration Utility on NetWare.

A multiple-UPS configuration is also know as a “redundant UPS” configuration
where one of several UPSs a) only partially shares the load or b) operates as a
stand-by to back up a faulty unit. Specifically, PowerChute Network Shutdown can
manage up to three Smart-UPS or Symmetra units (of the same model type)
providing redundant backup power to a single server. In this configuration, each
UPS in the system has its own Network Management Card (AP9617, 18, or 19) with
PowerChute Network Shutdown recognizing the entire configuration as a single
UPS.

Caution: In a multiple-UPS configuration, each UPS must have enough capacity
to carry all the electrical load of the computer system. So, for example, if you
had two UPSs in a multiple configuration, and one stops supplying power, the
other UPS must have enough capacity to continue supplying power to protect the
computer system.

For a multiple-UPS configuration, you must have PowerChute Network Shutdown
2.2 or greater. See also Requirements.

You can’t upgrade to a multiple-UPS configuration from a previous version of
PowerChute Network Shutdown: you must uninstall, install the new version, and
re-configure your options.

With a multiple configuration, PowerChute Network Shutdown always recognizes
and logs the events in the groups listed below (see the text on individual
events in the List of Events section in Help.html):

Network communication lost events
UPS communication lost events
UPS off
UPS on battery events
Environmental Monitoring Card events
Runtime Exceeded

For the Environmental Monitoring Card and Runtime
Exceeded events, any actions you configured for the event will be instigated
(see the Configuring Events section in Help.html).

Notes: With multiple-UPS configurations:

PCNS always considers either a) a low battery condition or b) a UPS off
condition as a critical event.
Two critical events in succession always cause a shutdown. In addition,
with any of these configurations, a critical event will cause an immediate
shutdown; no delay time will be counted.

For details on Advanced Configuration, see the Advanced Configuration
section in the Help Guide.
