1Metered Rack PDU User’s Guide
Introduction
Product Features
The American Power Conversion (APC
®
) Metered Rack Power Distribution Unit (PDU) is a stand-
alone, network-manageable power distribution device that monitors the current, voltage, and power for
the Rack PDU power outlets. You can manage a Rack PDU through its “Web Interface” , its “Command
Line Interface” , InfraStruxure
®
Central, or Simple Network Management Protocol (SNMP). (To use the
PowerNet MIB with an SNMP browser, see the PowerNet SNMP Management Information Base (MIB)
Reference Guide, available at www.apc.com.) Rack PDUs have these additional features:
• Voltage, current, power, and energy monitoring for the device, phase, and bank as applicable.
• Configurable alarm thresholds that provide network and visual alarms to help avoid overloaded
circuits.
• Three levels of user access accounts: Administrator, Device User, and
Read-Only User.
• 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, or FTP.
• E-mail notifications for Rack PDU and system events.
• SNMP traps, Syslog messages, and e-mail notifications based on the severity level or category of
the Rack PDU and system events.
• Security protocols for authentication and encryption.
Note: The Rack PDU does not provide power surge protection. To ensure that the
device is protected from power failure or power surges, connect the Rack PDU to an
APC Uninterruptible Power Supply (UPS).
Access Priorities for Logging on
Only one user at a time can log on to the Rack PDU. The priority for access, beginning with the highest
priority, is as follows:
• Local access to the command line interface from a computer with a direct serial connection to the
Rack PDU
• Telnet or Secure SHell (SSH) access to the command line interface from a remote computer
• Web access, either directly or through InfraStruxure Central
Note: See “SNMP” on page 70 for information about how SNMP access to the Rack
PDU is controlled.
