1Rack ATS AP44xx User Manual
Overview
The APC by Schneider Electric™ Rack Automatic Transfer Switch (ATS) with Network Management
Card 2 provides redundant power to single-corded equipment loads, such as servers. The Rack ATS has
two input power cords that supply power to the connected loads from both a primary and secondary
power source. If the primary source becomes unavailable or goes out of the configured power range, the
Rack ATS will switch to draw power from the secondary source without interrupting critical loads. You
can manage a Rack ATS through its Web User Interface (Web UI), its Command Line Interface (CLI),
StruxureWare™ Data Center Expert
(SNMP). (To use the PowerNet
(MIB) Reference Guide, available at www.apc.com.)
Product Features
The Rack ATS has these additional features:
• LED indicators on the front panel of the unit indicate operation conditions such as preferred
source, overload current, and Web connectivity. These conditions can also be monitored via the
CLI and Web UI.
• Various levels of access: Super User, Administrator, Device User, Read-Only, and Network-Only
User. (These have user name and password requirements.)
• A multiple-user login feature, which allows up to four users to be logged in simultaneously.
• Event and data logging. The event log is accessible by Telnet, Secure CoPy (SCP), File Transfer
Protocol (FTP), serial connection, or Web browser (using HTTPS access with SSL/TLS, or using
HTTP access). The data log is accessible by Web browser, SCP, or FTP.
• SNMP traps, Syslog messages, and e-mail notifications based on the severity level or category of
the Rack ATS and NMC system event.
• Security protocols for authentication and encryption.
• The ability to monitor sources and set source-transfer parameters via Web and CLI interfaces.
• Set alarm thresholds that provide network and visual alarms to help you prevent overloaded
circuits.
• Internal protection measures against short circuits. (See “Internal Protection Measures” on page 3
for details.)
NOTE: It is always recommended that you connect each ATS source to a Double Conversion
On-Line Uninterruptible Power Supply (UPS).

ATS units may include the following internal protection measures:
• Input relays in every
model open when their
source is disconnected
to help prevent electric
backfeed from one input
cord into another
(ATS 1).
• Two or four
non-replaceable fuses
(depending on the
model) help to protect
the ATS from short
circuits (ATS 2).
• Some 2U models have
circuit breakers to help
protect against bank
overload (ATS 3).
The rack ATS does not include power surge protection. To help protect your ATS from external power
surges, it is always recommended that you connect each ATS source to a Double Conversion On-Line
Uninterruptible Power Supply (UPS).
How Switching Works
1. You configure the ATS to accept power that meets the needs of your equipment by adjusting the
following settings (see “Configuration Tab” on page 78 for more details).
– Line VRMS: The ideal voltage for your equipment. Acceptable line voltages vary per ATS
model (see the specification sheet for your ATS model on www.apc.com).
– Transfer limits: The maximum and minimum voltages the ATS will accept before switching
sources. Transfer limits are meant to allow for small, acceptable surges and drops in power.
The ATS should not operate near the upper transfer limit for long periods of time.
– Transfer ranges: Pre-defined sets of transfer limits. You can configure up to three transfer
ranges, but you can enable only one transfer range at a time.
– Sensitivity: How long the ATS waits to determine whether or not it will switch sources.
High sensitivity provides extra responsiveness for delicate equipment. Low sensitivity helps to
prevent excessive switching in cases of fluctuating power inputs.
3Rack ATS AP44xx User Manual
2. The ATS constantly monitors the quality and amount of power coming from sources A and B. If
Source A is providing
power to the attached
equipment, while Source B
is isolated from the
attached equipment.
Firmware detects that
Source A is out of the
user-specified transfer range.
The input power from Source
A is removed by disengaging
the relays. (This allows for
out-of-phase switching and
significantly reduces the
opportunity for relay welding.)
Source B relays are
engaged. Source B
provides power to the
attached equipment.

one source begins to supply power that does not meet your settings, the ATS will disqualify that
source.
a. If the disqualified source is not in use, the ATS will generate an alarm to indicate that
redundancy has been lost.
b. If the disqualified source is in use, the ATS will switch to draw power from the other
available source.
If a preferred source is set, the ATS will wait 30 seconds to monitor that source. After 30 seconds,
if the preferred source becomes usable again, the ATS will switch back to the preferred source.
See an illustration of how the switch happens below.
NOTE: The entire switching process (described in step 2) takes a maximum of
10 milliseconds (ms) at high sensitivity, and 12 ms at low sensitivity.
Rack ATS AP44xx User Manual4
Types of User Accounts
The Rack ATS has various levels of access (Super User, Administrator, Device User, Read-Only User,
and Network-Only User), which are protected by user name and password requirements. Up to four
users are allowed to log on to the same Rack ATS simultaneously.
• An Administrator or the Super User can use all of the menus in the Web UI and all of the
commands in the CLI. Administrator user types can be deleted, but the Super User cannot
be deleted. The default user name and password for the Super User or an Administrator are
both apc.
NOTE: The Super User or an Administrator can manage another Administrator's account
(enable, disable, change password, etc).
• A Device User has read and write access to device-related screens. Administrative functions like Session Management under the Security menu and Firewall under Logs are unavailable.
• A Read-Only User has access to the same menus as a Device User, but without the ability to
change configurations, control devices, delete data, or use file transfer options. Links to
configuration options are visible but disabled. The event and data logs display no button to clear
the log. The default user name for this account is readonly, and the default password is apc.
• A Network-Only User can only log on using the Web UI and CLI (Telnet or SSH). A user with
network-only access has read/write permission to the network related menus only.
Watchdog Features
To detect internal problems and recover from unanticipated inputs, the Rack ATS uses internal, systemwide watchdog mechanisms. When it restarts to recover from an internal problem, a Network Interface
Restarted event is recorded in the event log.
Network interface watchdog mechanism
The Rack ATS implements internal watchdog mechanisms to help protect itself from becoming
inaccessible over the network. For example, if the Rack ATS does not receive any network traffic for 9.5
minutes (either direct traffic, such as SNMP, or broadcast traffic, such as an Address Resolution Protocol
[ARP] request), it assumes that there is a problem with its network interface and restarts. The network
interface watchdog mechanism is only enabled on an ATS that discovers an active network interface
connection at start-up.
Resetting the network timer
To help ensure that the Rack ATS does not restart if the network is quiet for 9.5 minutes, the Rack ATS
attempts to contact the default gateway every 4.5 minutes. If the gateway is present, it responds to the
Rack ATS, and the response restarts the 9.5-minute timer. If your application does not require or have a
gateway, specify the IP address of a computer that is running on the network and is on the same subnet.
The network traffic of that computer should restart the 9.5-minute time frequently enough to prevent the
Rack ATS from restarting.
5Rack ATS AP44xx User Manual
Getting Started
To start using the Rack ATS:
1. Install the Rack ATS using the Installation and Quick Start on www.apc.com.
2. Apply power and connect to your network. Follow the directions in the Installation and Quick Start.
3. Establish your network settings.
4. Begin using the Rack ATS with one of the following:
– The front panel. See “Front Panel” on page 11.
NOTE: The front panel allows you to view Rack ATS settings, but not configure them.
– The CLI. See “Command Line Interface” on page 17.
– The Web UI. See “Web UI” on page 70.
Establish Network Settings
IPv4 Initial Setup
You must define three TCP/IP settings for the Rack ATS before it can operate on the network:
• The IP address of the Rack ATS
• The subnet mask of the Rack ATS
• The IP address of the default gateway (only needed if you are going off segment)
NOTE: Do NOT use the loopback address (127.0.0.1) as the default gateway. Doing so disables the
network connection of the Rack ATS. To enable the network connection again, you must log on using a
serial connection and reset the TCP/IP settings to their defaults.
For detailed information on how to use a DHCP server to configure the TCP/IP settings at a Rack ATS,
see.“DHCP response options” on page 90
IPv6 Initial Setup
IPv6 network configuration provides flexibility to accommodate your requirements. IPv6 can be used
anywhere an IP address is entered on this interface. You can configure IPv6 using the CLI, the Web UI,
or DHCP.
TCP/IP Configuration Methods
Use one of the following methods to define the TCP/IP settings needed by the Rack ATS:
• Device IP Configuration Wizard (see “Device IP Configuration Wizard” on this page).
• BOOTP or DHCP server (see “DHCP and BOOTP configuration” on page 7).
• Local computer (see “Local access to the CLI” on page 8).
• Networked computer (see “Remote access to the CLI” on page 9).
.ini file utility
You can use the .ini file export utility to export .ini file settings from a configured Rack ATS to an
unconfigured Rack ATS. For more information, see “Create and import settings with the config file” on
page 108.
Rack ATS AP44xx User Manual6
Device IP Configuration Wizard
The Device IP Configuration Wizard runs on Microsoft® Windows® 2000, Windows Server® 2003,
Windows Server 2012, and on 32- and 64-bit versions of Windows XP
2008, Windows 7, Windows 8, and Windows 10 operating systems. The Device IP Configuration Wizard
supports cards that have firmware version 3.0.x or higher and is for IPv4 only.
To install the Device IP Configuration Wizard:
1. Go to www.apc.com.
2. Download the latest version of the Device IP Configuration Wizard.
3. Run the executable file (DeviceIPConfigurationWizard.exe).
NOTE: If you leave the Start a Web browser when finished option enabled, you can use apc
for both the user name and password to access the Rack ATS through your browser.
When Installed, the Device IP configuration Wizard is available through the Windows Start menu
options.
Configure TCP/IP settings with the Wizard
The Device IP Configuration Wizard can discover Rack ATS units that do not have an IP address
assigned. Once discovered, you can configure the IP address settings for the Network Management
Cards (NMCs).You can also search for devices already on the network by entering an IP range to define
the search. The Utility scans the IP addresses in the defined range and discovers Rack ATS units that
already have a DHCP-assigned IP address.
NOTE: For detailed information on the Utility, see FAQ article FA156064: go to www.apc.com, navigate
to Support > Resources & Tools > FAQS, then enter the article number in the search bar.
®
, Windows Vista®, Windows
NOTE: To use the DHCP Option 12 (AOS 5.1.5 or higher), see FAQ article FA156110.
DHCP and BOOTP configuration
The default TCP/IP configuration setting, DHCP, assumes that a properly configured DHCP server is
available to provide TCP/IP settings to the Rack ATS. You can also configure the setting for BOOTP.
A user configuration (INI) file can function as a BOOTP or DHCP boot file. For more information, see
“Create and import settings with the config file” on page 108.
If neither of these servers is available, see “Device IP Configuration Wizard” on page 7.
BOOTP
For the Rack ATS to use a BOOTP server to configure its TCP/IP settings, it must find a properly
configured RFC951-compliant BOOTP server.
1. In the BOOTPTAB file of the BOOTP server, enter the Rack ATS’s MAC address, IP address,
subnet mask, and default gateway, and, optionally, a bootup file name. Look for the MAC address
on the bottom of the Rack ATS.
2. When the Rack ATS reboots, the BOOTP server provides it with the TCP/IP settings.
– If you specified a bootup file name, the Rack ATS attempts to transfer that file from the
BOOTP server using TFTP or FTP. The Rack ATS assumes all settings specified in the bootup
file.
– If you did not specify a bootup file name, you can configure the other settings of the Rack ATS
remotely through its Web UI (see “Web UI” on page 70) or CLI (see “Remote access to the
CLI” on page 9) The default user name and password are apc for both interfaces. To create a
bootup file, see your BOOTP server documentation.
7Rack ATS AP44xx User Manual
DHCP
You can use an RFC2131/RFC2132-compliant DHCP server to configure the TCP/IP settings for the
Rack ATS.
1. The Rack ATS sends out a DHCP request that uses the following to identify itself:
– A Vendor Class Identifier (APC by default)
– A Client Identifier (by default, the MAC address of the Rack ATS)
– A User Class Identifier (by default, the identification of the application firmware installed on the
Rack ATS)
– A Host Name (by default, apcXXYYZZ with XXYYZZ being the last six digits of the ATS serial
number). This is known as DHCP Option 12.
2. A properly configured DHCP server responds with a DHCP offer that includes all the settings that
the Rack ATS needs for network communication. The DHCP offer also includes the Vendor
Specific Information option (DHCP option 43). The Rack ATS can be configured to ignore DHCP
offers that do not encapsulate the APC cookie in DHCP option 43 using the following
hexadecimal format. (The Rack ATS does not require this cookie by default.)
Option 43 = 01 04 31 41 50 43
– The first byte (01) is the code.
– The second byte (04) is the length.
– The remaining bytes (31 41 50 43) are the APC cookie.
See your DHCP server documentation to add code to the Vendor Specific Information option.
NOTE: By selecting the Require vendor specific cookie to accept DHCP Address check
box in the Web UI, you can require the DHCP server to provide an “APC” cookie, which
supplies information to the Rack ATS.
Local access to the CLI
You can use a local computer to connect to the ATS and access the CLI.
1. Select a serial port at the local computer and disable any service that uses that port.
2. Use the serial communication cable (940-0144A) to connect the selected port to the serial port on
the front panel of the ATS.
3. Run a terminal program (such as HyperTerminal
8 data bits, no parity, 1 stop bit, and no flow control. Save the changes.
4. Press
ENTER up to 3 times to display the User Name prompt.
5. Use apc for the user name and password.
6. See “Configure TCP/IP settings in the CLI” on page 9 to finish the configuration.

) and configure the selected port for 9600 bps,
Rack ATS AP44xx User Manual8
Remote access to the CLI
From any computer on the same network as the Rack ATS, you can use ARP and Ping to assign an IP
address to the Rack ATS, and then use Telnet to access the CLI of that Rack ATS and configure the
other TCP/IP settings.
NOTE: After the IP address of the Rack ATS is configured, you can access the Rack ATS using Telnet or
SSH, without first using ARP and Ping. You must enable SSH before using it, so Telnet is required for
initial CLI configuration.
1. Use ARP to define an IP address for the Rack ATS and use the MAC address of the Rack ATS in
the ARP command. For example, to define an IP address of 156.205.14.141 for a Rack ATS that
has a MAC address of 00 c0 b7 63 9f 67, use one of the following commands:
– Windows command format:
arp -s 156.205.14.141 00-c0-b7-63-9f-67
– LINUX command format:
arp -s 156.205.14.141 00:c0:b7:63:9f:67
NOTE: The MAC address can be found on the bottom of the ATS.
2. Use Ping with a size of 113 bytes to assign the IP address defined by the ARP command. For
example:
– Windows command format:
ping 156.205.14.141 -l 113
– LINUX command format:
ping 156.205.14.141 -s 113
3. Use Telnet to access the Rack ATS at its newly assigned IP address. (For example:
telnet 156.205.14.141) Use apc for both user name and password.
(See “Remote access to the CLI” on page 17)
See “Configure TCP/IP settings in the CLI” on page 9 to finish the configuration.
Configure TCP/IP settings in the CLI
1. Log on to the CLI. See “Log on to the CLI” on page 17.
2. Contact your network administrator to obtain the IP address, subnet mask, and default gateway
for the Rack ATS.
3. Use these three commands to configure network settings. (Text in italics indicates a variable.)
For each variable, type a numeric value that has the format xxx.xxx.xxx.xxx. For example,
to set a system IP address of 156.205.14.141, type the following command and press
tcpip -i 156.205.14.141
NOTE: You can also enter all three command options on the same line:
ENTER. The Rack ATS restarts to apply the changes.

Command Line Interface
You can use the Command Line Interface (CLI) to configure, manage, and monitor the status of the Rack
ATS. Additionally, the CLI enables you to create scripts for automated operation. You can configure all
parameters of a Rack ATS (including those for which there are not specific CLI commands) by using the
CLI to transfer an INI file to the Rack ATS. The CLI uses XMODEM to perform the transfer. However, you
cannot read the current INI file through XMODEM.
Log on to the CLI
To access the CLI, you can use either a local (serial) connection or a remote (Telnet or SSH) connection
with a computer on the same network as the Rack ATS.
Local access to the CLI
For local access, use a computer that connects to the Rack ATS through the serial port to access the
CLI:
1. Select a serial port at the computer and disable any service that uses that port.
2. Connect the serial communication cable (940-0144A) from the selected serial port on the
computer to the Serial port on the Rack ATS.
3. Run a terminal program (e.g., HyperTerminal) and configure the selected port for 9600 bps, 8
data bits, no parity, 1 stop bit, and no flow control.
4. Press
ENTER. At the prompts, enter your user name and password.
Remote access to the CLI
You can choose to access the CLI through Telnet and/or SSH, depending on which is enabled. Telnet is
enabled by default, though you do not have to enable either. A Super User or Administrator can enable
or disable either of these access methods through the CLI (see “console” on page 29) or the Web UI
(see “Configure CLI access” on page 95).
Telnet for basic access
Telnet provides the basic security measure of authentication by user name and password, but not the
high-security benefits of encryption.
To use Telnet to access the CLI:
1. At a command prompt, type telnet and the IP address for the Rack ATS (for example, telnet
139.225.6.133, when the Rack ATS uses the default Telnet port of 23), and press
If the Rack ATS uses a non-default port number (from 5000 to 32768), you must include a colon
or a space, depending on your Telnet client, between the IP address (or DNS name) and the port
number. (These are commands for general usage; some clients do not allow you to specify the
port as an argument and some types of Linux might require extra commands).
2. Enter the user name and password (by default, apc and apc for the Super User and
Administrator, or device and apc for a Device User).
3. If you cannot remember your user name or password, see “Recover from a Lost Password” on
page 10.
SSH for high-security access
If you use the high security of SSL/TLS for the Web UI, use SSH for access to the CLI. SSH encrypts
user names, passwords, and transmitted data. The interface, user accounts, and user access rights are
the same whether you access the CLI through SSH or Telnet, but to use SSH, you must first configure
SSH and have an SSH client program installed on your computer. See the Security Handbook on
www.apc.com for more information on configuring and using SSH.
ENTER.

Command Syntax
ItemDescription
-Options are preceded by a hyphen.
< >Definitions of options are enclosed in angle brackets.
For example:
[ ]If a command accepts multiple options or an option accepts mutually exclusive arguments, the values
may be enclosed in brackets.
|A vertical line between items enclosed in brackets or angle brackets indicates that the items are
mutually exclusive. You must use one of the items.
Example of a command that supports multiple options:
ftp [-p <port number>] [-S <enable | disable>]
In this example, the ftp command accepts the option -p, which defines the port number, and the option
-S, which enables or disables the FTP feature.
To change the FTP port number to 5010, and enable FTP:
1. Enter the ftp command, the port option, and the argument 5010:
ftp -p 5010
2. After the first command succeeds, enter the ftp command, the enable/disable option, and the
enable selection:
ftp -S enable
Example of a command that accepts mutually exclusive arguments for an option:
-dp <device password>
alarmcount -p [all | warning | critical]
In this example, the option -p accepts only three arguments: all, warning, or critical. For example,
to view the number of active critical alarms, type:
alarmcount -p critical
The command will fail if you type an argument that is not specified.
