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
s
erial 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.
Refer to the

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 assume
s the “Master” role, with the Master PDU 4/4’s
CONTROL OUT 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. Additio
nal 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.
