Rack ATS AP44xx User Manual2
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
®
, EcoStruxure IT, or Simple Network Management Protocol
(SNMP). (To use the PowerNet
®
MIB with an SNMP browser, see the Management Information Base
(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).
