Switched Rack PDU Installation and Quick-Start Manual 1

Preliminary Information

Features of the Switched

Rack PDU

American Power Conversion’s Switched Rack Power Distribution Unit

(PDU) is a stand-alone, network-manageable device that allows

programmable control of 8, 16, or 24 power outlets through its Web,

SNMP, or Control Console network interfaces.

Using the Switched Rack PDU, you can do the following:

• Set the following values for each outlet independently:

–Power On Delay

– Power Off Delay

– Reboot Duration

• Set up power sequencing to avoid inrush current at system start-up.

• Manage access to outlets through the following three types of user

accounts:

– Administrator

– Device Manager

– Outlet User

• Upgrade the Switched Rack PDU firmware without affecting the

outlet state.

• Provide up to twenty-four Outlet User accounts.

• Import the event logs into a spreadsheet application.

• Know that passwords are secure through the Switched Rack PDU’s

basic and MD5 authentication.

• 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, APC does not recommend plugging

the unit directly into any unprotected power source, such as

a wall outlet.

Warn

The Switched Rack PDU contains a non-replaceable

lithium coin cell battery. Do not attempt to replace the

battery.
