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 to minimize 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.)

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.

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 venti
lation space on both sides of the units (minimum 2”),
especially if units are being stacked.
