Switched Rack Power Distribution Unit
1
Preliminary Information
Features
This booklet provides information on installing and
operating Switched Rack Power Distribution Units
(PDUs). Each PDU is a stand-alone, network-
manageable device that allows programmable
control of power outlets through its Web, Telnet,
SNMP, SSH, or InfraStruXure
®
Manager interfaces.
Using the Switched Rack PDU, you can do several
things:
• Set the following values for each outlet
independently:
–Power On Delay
– Power Off Delay
– Reboot Duration
• Set up power sequencing to avoid an in-rush
of current at system start-up.
• Manage access to outlets through the
following four types of user accounts:
– Administrator
– Device User
– Outlet User
– Read-Only User
• Upgrade the Switched Rack PDU firmware
without affecting the outlet state.
• Provide an independent Outlet User account
for each outlet.
• Import the event and data logs into a
spreadsheet application.
• Protect data using the advanced security
protocols of the Switched Rack PDU.
• Monitor the aggregate current draw of the
Switched Rack PDU, which helps avoid
overloaded circuits.
Note. The Switched Rack PDU
does not provide power protection.
Therefore, American Power
Conversion (APC
®
) does not
recommend plugging the unit
directly into any unprotected
power source, such as a wall
outlet.
Display interface
The display interface on the Switched Rack PDU
shows the aggregate current being used by the PDU
and its attached devices. An alarm occurs if the
aggregate current is above the high threshold value
or below the low threshold value that you configure.
