Introduction
Product Description
Features of the Rack Automatic Transfer Switch
The American Power Conversion (APC®) Rack Automatic Transfer Switch (ATS) is a
high-availability switch with two input power cords, one for each AC line, which enable
the Rack ATS to provide redundant power.
You can manage a Rack ATS through its Web interface, its control console interface,
the InfraStruXure
(SNMP).
• Access the Web interface using Hypertext Transfer Protocol (HTTP), or using secure
HTTP (HTTPS) with Secure Sockets Layer (SSL).
• Access the control console through a serial connection, Telnet, or Secure SHell
(SSH).
• Use InfraStruXure Manager to monitor and manage your Rack ATS.
• Use an SNMP browser and the APC PowerNet
®
Manager and Central, or Simple Network Management Protocol
®
Management Information Base
(MIB) to manage your Rack ATS.
Automatic Transfer Switches have these features:
• Configurable alarm thresholds that provide network and visual alarms to help you
prevent overloaded circuits.
• LED indicators on the front panel of the unit indicate operation, such as preferred
source, overload current, and web connectivity. These can also be monitored via
serial and the Web interface.
• The ability to monitor sources and set preferred transfer parameters via web and
USER’S GUIDE

console interfaces.
• Three levels of user access accounts: Administrator, Device User, and
Read-Only User.
1
• 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, or using HTTP access). The data log is accessible by Web
browser, SCP, and FTP.
• SNMP traps, Syslog messages, and e-mail notifications based on the severity level
or category of the Rack ATS and system events.
• Security protocols for authentication and encryption.
The Rack ATS does not provide power surge protection. To ensure
that the device is protected from power failure or power surges, connect the Rack ATS to an APC Uninterruptible Power Supply (UPS).
Initial setup
You must define three TCP/IP settings for the Automatic Transfer Switch before it can
operate on the network.
• IP address of the Rack ATS
• Subnet mask
• IP address of the default gateway
Do not use the loopback address (127.0.0.1) as the default
gateway address. Doing so disables the Rack ATS. You must then
log on using a serial connection and reset TCP/IP settings to their
defaults.
To configure the TCP/IP settings, see the Installation and Quick Start
Manual provided as a PDF file on the APC Automatic Transfer Switch
Utility CD, and as a printed manual.
To use a DHCP server to configure the TCP/IP settings at a Rack
ATS, see TCP/IP and Communication Settings.

Access Procedures
Overview
The Rack ATS has two internal interfaces (control console and Web interface) that
allow you to manage the Rack ATS.
For more information about the internal user interfaces, see Control
Console and Web Interface.
The SNMP interface also allows you to use an SNMP browser with the PowerNet
Management Information Base (MIB) to manage the Rack ATS.
To use the PowerNet MIB with an SNMP browser, see the PowerNet SNMP Management Information Base (MIB) Reference Guide, which
is provided on the APC Automatic Transfer Switch Utility CD.
Access priority for logging on
Only one user at a time can log on to the Rack ATS. The priority for access, beginning
with the highest priority, is as follows:
• Local access to the control console from a computer with a direct serial connection to
the Rack ATS.
• Telnet or Secure SHell (SSH) access to the control console from a remote computer.
• Web access, either directly or through the InfraStruXure Manager.
See SNMP for information about how SNMP access to the Rack
ATS is controlled.

Types of user accounts
The Rack ATS has three levels of access (Administrator, Device User, and Read-Only
User), which are protected by user name and password requirements.
• An Administrator can use all of the menus in the Web interface and control console.
The default user name and password are both apc.
• A Device User can access only the following:
– In the Web interface, the menus on the Unit tab and the event and data logs,
accessible under the Events and Data headings on the left navigation menu of the
Logs tab.
– In the control console, the equivalent features and options. A Device User can also
access the event log in the control console by pressing
The default user name is device, and the default password is apc.
• A Read-Only User has the following restricted access:
– Access through the Web interface only.
– Access to the same menus as a Device User, but without the capability to change
configurations, control devices, delete data, or use file transfer options. Links to
configuration options are visible but are disabled, and the event and data logs
display no button to clear the log.
The default user name is readonly, and the default password is apc.
To set User Name and Password values for the three account types,
see Setting user access (Administration>Security>Local
Users>options).
You must use the Web interface to configure values for the
Read-Only User.

Recovering from a Lost Password
You can use a local computer (a computer that connects to the Rack ATS or other
device through the serial port) to access the control console.
1. Select a serial port at the local computer, and disable any service that uses that
port.
2. Connect the serial cable (APC part number 940-0144A) to the selected port on the
computer and to the configuration port at the Rack ATS.
®
3. Run a terminal program (such as HyperTerminal
for 9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control.
) and configure the selected port
4. Press
unable to display the User Name prompt, verify the following:
– The serial port is not in use by another application.

Upgrading Firmware Through a Serial Connection
For a complete description of how to download a firmware upgrade
for your Rack ATS, see Upgrading Firmware. That section also
explains how to use network-based file transfer tools, which complete a firmware upgrade more quickly than the XMODEM protocol,
which uses a serial connection.
You can use a local computer that connects to the Rack ATS through the serial port on
the front panel of the unit.
1. Obtain the individual firmware modules (the AOS module and the application
module) from www.apc.com/tools/download.
2. Select a serial port at the local computer and disable any service that uses that port.
3. Connect the provided serial cable (APC part number 940-0144A) to the selected
port and to the serial port at the Rack ATS.
4. Run a terminal program such as HyperTerminal, and configure the selected port for
9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control. Save the changes.
5. Press
6. Enter the Administrator user name and password (apc by default for both).
7. From the Control Console menu, select System, then Tools, then File Transfer,
then XMODEM; type Yes at the prompt to continue.
8. Change the terminal program’s baud rate to match your selection, and press
ENTER. A higher baud rate causes faster upgrades.
9. From the terminal program’s menu, select the binary AOS file to transfer using
XMODEM-CRC. After the XMODEM transfer is complete, set the baud rate to 9600.
The Rack ATS automatically restarts.

Watchdog Features
Overview
To detect internal problems and recover from unanticipated inputs, the Rack ATS uses
internal, system-wide watchdog mechanisms. When it restarts to recover from an
internal problem, a System: Warmstart event is recorded in the event log.
Network interface watchdog mechanism
The Rack ATS implements internal watchdog mechanisms to 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 itself.
USER’S GUIDE
Automatic Transfer Switch
®
11
Resetting the network timer
To 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 that 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 most of the time and is on the same subnet.
The network traffic of that computer will restart the 9.5-minute timer frequently enough
to prevent the Rack ATS from restarting.

Control Console
How to Log On
Overview
You can use either a local (serial) connection, or a remote (Telnet or SSH) connection
to access the control console.
Use case-sensitive User Name and Password entries to log on (by default, apc and
apc for an Administrator, or device and apc for a Device Manager, which is the same
user account as Device User in the Web interface). A Read-Only User has no access to
the control console.
If you cannot remember your user name or password, see
Recovering from a Lost Password.
Remote access to the control console
You can access the control console through Telnet or Secure SHell (SSH). Telnet is
enabled by default. Enabling SSH disables Telnet.
To enable or disable these access methods:
• In the Web interface, on the Administration tab, select Network on the top menu
bar, and then the access option under Console on the left navigation menu.
• In the control console, use the Telnet/SSH option of the Network menu.
USER’S GUIDE
Automatic Transfer Switch
®
13
Telnet for basic access. Telnet provides the basic security of authentication by user
name and password, but not the high-security benefits of encryption. To use Telnet to
access the control console:
1. From a computer on the same network as the Rack ATS, at a command prompt,
type telnet and the System IP address for the Rack ATS (for example
139.225.6.133, when the Rack ATS uses the default Telnet port of 23), and press
ENTER.
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.
2. Enter the user name and password (by default, apc and apc for an Administrator, or
device and apc for a Device Manager, which is the same user account as Device
User in the Web interface).
SSH for high-security access. If you use the high security of SSL for the Web
interface, use Secure SHell (SSH) for access to the control console. SSH encrypts user
names, passwords, and transmitted data. The interface, user accounts, and user
access rights are the same whether you access the control console through SSH or
Telnet, but to use SSH, you must first configure SSH and have an SSH client program
installed on your computer.
telnet
Local access to the control console
For local access, use a computer connected by serial cable to the Rack ATS through
the serial port on the front panel of the unit:
1. Select a serial port at the local computer, and disable any service that uses that
port.
2. Use the supplied serial cable (APC part number 940-0144A) to connect the
selected port to the serial port on the front panel of the Rack ATS.

How to Log On
Overview
You can use the DNS name or System IP address of the Rack ATS for the URL
address of the Web interface. Use your case-sensitive user name and password to log
on. The default user name differs by account type:
• apc for an Administrator
• device for a Device User
• readonly for a Read-Only User
The default password is apc for all three account types.
If you are using HTTPS as your access protocol, your login credentials
are compared with information in a server certificate. If the certificate
was created with the APC Security Wizard, and an IP address was
specified as the common name in the certificate, you must use an IP
address to log on to the Rack ATS. If a DNS name was specified as the
common name on the certificate, you must use a DNS name to log on.
