Thinklogical’s easy to use PDU 4/4 Power Distribution Unit is an AC Power Switch that remotely controls the
power to eight separate devices which may be switched off and on as desired. This allows system
administrators, while communicating with the control terminal through a serial interface, to restart a “locked up”
network device from anywhere on the network.
•Controls all devices with simple Power Off/On commands to reboot any one port, multiple ports, port groups or all
devices.
•Power restarts can be sequenced using programmed time delays tominimize surge or to allow drive spin-up time.
•Rear panel LEDs show the status of each port.
Any configuration can be easily expanded by cascading additional PDU 4/4 chassis with a single serial
cable for each added chassis. Up to sixteen PDU 4/4s can be cascaded together to control multiple systems from
one common user interface. A single serial interface integrates the control of all PDU 4/4s in any standard
application. (See Cascading the PDU Chassis on page 8.)
1. The PDU 4/4 Remote AC Power Distribution Unit
Mounting the PDU 4/4
You may choose to rack mount your PDU 4/4 or place it on a shelf or desktop (feet included). The front panel
LCD and navigation buttons should always be accessible. All connections are made at 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 mount 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.
8 Mounting

2 Mounting bracket
screws in four places.
RACK-MOUNT OR DESK-TOP OPTIONS:
Like all Thinklogical rack-mountable extenders,
the PDU 4/4 can be mounted in a standard EIA
19" rack or on a shelf or desk-top.
After removing power from the unit, each
mounting bracket, which is secured by four
screws, can be safely removed for desk-top
mounting without removing the cover.
All screws should be reinstalled after the
brackets have been removed.
Note: Be sure to leave adequate ventilation space on both sides of the units (minimum 2”),
especially if units are being stacked.

*Offset Current (Tare) is only available from the front panel. This menu option sets a zero current reference and stores it
in non-volatile memory. To use this feature all ports must be off. Once the ports are off, set the Offset Current Tare to Yes,
it will revert back to No when the calibration is complete.
Convection Cooling
The PDU 4/4 does not require special cooling or ventilation other than what is normally provided in a standard
equipment rack. If mounted in an enclosed rack, the rack should have a ventilation fan to provide adequate
airflow through the unit(s).
Connecting the PDU 4/4
All physical connections to the product use industry-standard connectors. All connections are found at
the rear of the unit.
The rear panel consists of (2) AC Power Cords, (2) Circuit Breakers, (8) AC Power Outlets, (8) Port Status
LEDs, (1) USB Firmware Upgrade Port and (2) RJ45 Console Ports.

The Rear Panel
Power Connections
The rear panel features two outlet banks. Each bank consists of (1) AC Input Power Cord, (1) Power
Switch/Circuit Breaker, and (4) AC Power Outlets.
Bank 1 provides AC output power to Ports 1 through 4
Bank 2 provides AC output power to Ports 5 through 8
Each AC Input Power Cord is outfitted with a NEMA 5-15P plug. Each Bank also has a 15 Amp Power
Switch/Circuit Breaker that supplies AC power to the bank of four switched outlets and to the internal power
supply. If only one Power Switch/Circuit Breaker is turned on, the internal, redundant power supply will power
the PDU and that one bank will provide AC output. If both banks are off, all outputs will be off.
The four switched AC outlets per bank are NEMA 5-15R, nominal-115VAC power outlets. Bank 1 consists of
Ports/Outlets 1 through 4 and Bank 2 consists of Ports/Outlets 5 through 8. Each outlet is independently
controlled and can switch up to 10 Amperes. However, the total power draw for each bank of 4 outlet ports
must not exceed 15 Amperes.
Note: The total power draw for each bank of 4 outlet ports must not exceed 15 Amperes.
The two internal power supplies that are used to power the PDU system are redundant. This feature will allow
the unit to maintain power in the event of a DC Power Supply failure. Upon recovery from a power failure, the
PDU will return all Ports to the same state they were in prior to the power loss.
Status LEDs
The LEDs on the rear panel correspond to each of the (8) Switched AC Outlets. (For example, LED 1 shows
the status of Outlet/Port 1, LED 2 shows the status of Outlet/Port2, etc.) When the status light of an Outlet/Port
is green, the Outlet/Port has power.
USB Firmware Upgrade Port
There is a USB-B connector on the rear panel of the PDU for firmware upgrades. Firmware updates are
through a USB cable and an application that runs on a Windows (2000, XP, or Vista) PC.
Please visit https://www.thinklogical.com for updates and instructions.
Serial Interface
The PDU 4/4 features (2) RJ45 serial connectors, labeled CONTROL IN andCONTROL OUT, on the rear
panel. If cascading multiple PDU units, the first PDU will be connected to the controlling terminal using the
CONTROL IN port. The CONTROL OUT port will be connected to the CONTROL IN port of the next unit using
a straight-through RJ45 cable, and so on.

Installation
The PDU is designed to stand alone or to connect to a
Thinklogical Secure Console Server®. Each device port
of the Secure Console Server is a compatible RS-232
serial port designed to connect to the PDU’s CONTROL
IN port. The PDU is installed by first connecting to the
device port using commands in the Console Server, then
once connected, by using PDU commands.

Use an Ethernet cable to connect the desired device port to the PDU's CONTROL IN port. The connection is made
with the device port configured as follows:
Port Setting for your Terminal Device
If your switch does not have a dedicated 'Power Manager' port, you may configure a serial port to the following
settings:
•Configure an RS-232 serial port as a DTE (Data Terminal Equipment) port.
•Configure the port for 9600 baud, 8 data bits, No Parity, 1 Stop Bit.
Cascading the PDU Chassis
If more than eight switched AC Power ports are required, the PDU 4/4 configuration can be expanded by daisy-
chaining up to sixteen (16) PDU 4/4 chassis. The first PDU 4/4 assumes the “Master” role, with the Master PDU 4/4’s
CONTROLOUT Port connected to the next chassis CONTROL IN Port by an RJ45 serial cable.
Box IDs
Units are only assigned master or slave status after logging in, so connect cascaded units prior to login.Before login,
all boxes display a box ID of 0. The first box assumes the Master box ID of 1. The top-left LED of the upper RJ-45
connector illuminates at login to indicate which is the Master unit. Additional PDU 4/4 boxes are designated a “Slave”
status and are automatically designated with the next sequential box ID (numbered 2 through 16). All commands
issued to the master unit referencing a slave unit will be passed on to the designated box. The program parameters
for each PDU 4/4 are stored in that unit. The Master unit only passes commands to the slave units.

PDU 4/4 Product Manual, Rev. A November 2020
Page 9
Note: If an intermediate unit in a daisy-chain of PDU 4/4’s loses power, the control and operation of the
PDU 4/4 configuration is interrupted at the unit without power.
Program Storage
All programmed data in the PDU 4/4 is stored in non-volatile memory. In the event of a power failure, the PDU 4/4
will return each port to its previous state (on or off) when power returns to the unit.
Note: Many PC-based communications packages can buffer the entered and displayed serial data so
that it may be copied and saved to a file. Users can then keep a copy of the programmed data for
reference.
Communicating with the PDU 4/4
Programming the System
The PDU 4/4 uses a simple serial user interface. It accepts commands from a serial terminal or terminal emulation
package. The command language also provides status information upon request.
In order to enter a command function, the user must gain access to the PDU 4/4 COMMAND MODE by entering a
password to log in. Each command is completed by pressing ‘Enter’ or ‘Carriage Return’ (<CR>).
Note: In this document, ‘Enter’, ‘Return’ and <CR> represent the same action.
Programming Access
Once connected to the PDU 4/4’s CONTROL IN serial port, the following access and programming commands
may be used. Invalid commands or unauthorized access attempts will not affect the PDU 4/4. The programming
interface will automatically log out after 5minutes of idle time.
1. Connect your programming terminal to the CONTROL IN port.
2. Press ‘Enter’ on the keyboard to establish communication. Your display should show “Password:”
If you do not get a Password prompt (or other activity), check your connections and your terminal’s configuration.
Log In
The PDU 4/4 is password protected at Log In. The factory-set password is pass (case-sensitive) which should be
changed by the System Administrator.
When Logged In, the command prompt will display PDU 4/4>
Commands
Command Principles
Serial Access
Commands are executed from the Serial terminal. You must log in orderto access any programming commands.
Abbreviation
Commands may be abbreviated by typing only enough characters to differentiate 1 command from another.
Ports and Groups
Commands can be entered for individual Ports, either by name or by number; for a range of port numbers separated
by a dash (e.g., 5-8), any combination of port numbers, separated by a comma (e.g., 1,4,5,8); or for a Port Group.
A Port Group is created by assigning the same name to more than one Port. (The example group name Sun will be
used throughout this instruction.) The port name can then beused in a PDU 4/4 command.
Global Commands
For configurations using multiple PDU 4/4 chassis, many commands will accept a box ID of zero (0) to
generate a Global Command that will execute the desired operation in all connected boxes.
Global commands include 0(zero) to operate all connected PDU 4/4 box ID’s, and ALL or all for all port IDs within a
chassis or a number of cascadedchassis.
