The Logical Solution
Thinklogical‟s Power Distribution Unit (PDU 4/4) is an AC Power Switch that provides the ability to
remotely control the power to eight devices. It gives system administrators the capability to restart a
“locked up” network device from anywhere on their network. The PDU 4/4 provides eight individuallycontrolled AC power outlets that are switched off and back on as desired. The PDU 4/4 communicates
with its control terminal using a serial interface.
The easy to use, PDU 4/4 provides the means to control all devices with simple commands to turn
Power Off / On to reboot any one port, multiple ports, port groups or all devices. Power restarts can be
sequenced using programmed time delays to minimize surge or allow drive spin-up time. Rear panel
LEDs are also provided to show the status of each port.
Your configuration can be easily expanded by adding PDU 4/4 boxes and a serial cable for each. A
single serial interface integrates the control of all PDU 4/4s in your application. Up to sixteen PDU 4/4s
can be cascaded together to control multiple systems from one common user interface.
Each PDU 4/4 utilizes two banks of four outlets, each outlet individually switches 10 Amperes maximum
with each bank rated at 15 Amperes total. The PDU 4/4 is designed for rack mounting (1U) or desktop.

All physical connections to the product use industry-standard connectors.
Mounting the PDU 4/4
You may choose to rack mount your PDU 4/4 or place it on a shelf or desktop (rubber feet
included). The front panel display should be visible and front panel buttons need only to be
accessible if initial setup of the system is required. All connections are made to the rear of the
chassis.
Rack Mount or Desktop
The PDU 4/4 may be installed in an EIA-standard 19 inch rack (1U tall), or placed on a shelf or
desktop. For shelf/desktop use, rubber feet are provided and the rack mounted brackets may be
removed. The PDU 4/4 chassis does not need to be opened or accessed. The sturdy metal case
allows units to be stacked, as required.
Note: Be sure to leave adequate ventilation space on both sides of the units,
especially if units are being stacked. Each rack mount bracket is held on by 4
screws. The brackets may be positioned so that the unit sits forward or recesses in
your rack. If the brackets are removed or repositioned, it is not necessary to re-use
the extra rack mount screws.
