2.1 Mounting the PDU

The PDU supports four primary mounting
configurations: 1U Rack, 0U Rack, Wall and
Under-Counter.

Note: Regardless of configuration, the user must determine the
fitness of hardware and procedures before mounting. The PDU
and included hardware are designed for common rack and rack
enclosure types and may not be appropriate for all applications.
Exact mounting configurations may vary.

1-1 1U Rack Mounting: Attach the PDU to the

rack by inserting four user-supplied screws A
through the PDU mounting brackets B and into
the mounting holes of the rack rail as shown.

1-2 0U Rack Mounting: Remove the screws C

attaching the mounting brackets to the PDU,
change the orientation of the brackets as shown
and reattach the brackets. Use only the screws
supplied by the manufacturer or their exact
equivalent (#6-32, 1/4" flat head). Attach the
PDU vertically by inserting two or more user­supplied screws A through the PDU mounting
brackets B and into mounting points in the rack
or rack enclosure.

1-3 Wall or 1-4 Under-Counter Mounting:

Remove the screws C attaching the mounting
brackets to the PDU, change the orientation of the
brackets as shown and reattach the brackets. Use
only the screws supplied by the manufacturer or
their exact equivalent (#6-32, 1/4" flat head).

2.2 Connecting the PDU

The PDU includes two AC power inputs: Primary
and Secondary. The Primary input cord is
permanently attached to the rear of the PDU.

The Secondary input cord is detachable and
connects to the IEC power inlet 2 at the rear of
the PDU (PDUMH15AT,PDUMH15ATNET ­IEC-320-C14 inlet; PDUMH20AT,
PDUMH20ATNET - IEC-320-C20 inlet).

2-1 To connect the Secondary input cord:

Form a loop in the Secondary cord 1.
secure the juncture of that loop to the Primary
cord B with a zip tie. Be sure the zip tie is
secured around the Secondary and Primary
cords, as well as through the loop created in
the Secondary cord C. (See diagram). Note:

Give the cord as much slack as possible
between the loop and the cord’s outlet.

Once you’ve secured the two cords together 2.
and ensured that the Secondary cord has a
comfortable amount of slack, insert the
Secondary cord outlet into the IEC power inlet.

2-2 Connect Input Plug Adapters (Optional -

Models PDUMH20AT, PDUMH20ATNET
Only): The PDU includes two adapters that

convert one or both of the L5-20P input plugs to
5-20P input plugs. Connecting the adapters is
optional. The PDU will function normally without
connecting the adapters.

2-3 Connect Secondary Input Cord to PDU:

Although the PDU will operate without
connecting the Secondary input cord, the
Secondary input is required for the PDU's
Automatic Transfer Switch function.

2-4 Connect PDU Input Plugs: (See the

Configuration and Operation section for more
information.) Connect the Primary input plug A
to a preferred source of grounded 120V AC
power, such as a SmartOnline™ UPS System. The
UPS system must not share a circuit with a heavy
electrical load (such as an air conditioner or
refrigerator). Under normal operating conditions,
the PDU will distribute AC power from the
Primary input source. Connect the Secondary
input plug B to an alternative source of grounded
120V AC power, such as a redundant
SmartOnline UPS System. The UPS system must
not share a circuit with a heavy electrical load
(such as an air conditioner or refrigerator). Do not
plug the Secondary input into the same power
source as the Primary input. The PDU will
distribute AC power from the Secondary input
only if the Primary input becomes unavailable.

Note: Immediately after the PDU is connected to live AC
power, you may notice a series of soft clicking sounds emitted by
electrical relays within the PDU. The relays may also click
occasionally during the operation of the PDU. This is normal.

3 Connect Equipment to PDU: Do not exceed

the load rating of the PDU. The total electrical
current used by the PDU will be displayed on the
digital meter in amperes. Each outlet includes a
green LED that illuminates when the outlet is
receiving AC power.

2.3 Networking the PDU

Note: The MAC address of the PDU (a 12-digit string in this format: 000667xxxxxx) is printed on a label attached to the PDU enclosure.
The MAC address is also printed on a label attached to the internal network card.

(Only Applicable to Models with SNMP Network Card Installed)

If your network's DHCP server will assign a dynamic IP address to the PDU automatically, go to Step

4-1

. If you will assign a static IP address to the PDU manually, go to Step

5-1

. If you are uncertain which
method to use, contact your network administrator for assistance before continuing the installation
process.

2.3.1 Dynamic IP Address Assignment

4-1 Connect PDU to Network: While the

PDU is powered, connect a standard Ethernet

A

patch cable to the RJ-45 Ethernet port

on the

A

PDU. Note: This port is not compatible with PoE
(Power over Ethernet) applications. The PDU

will attempt to obtain an IP address via DHCP.
This may take as long as several minutes,
depending on your network environment.

4-1

4-2 Discover IP Address: Contact your network administrator to determine which dynamic IP address

has been assigned to the PDU by the DHCP server. The PDU can be identified on the DHCP server by
referring to its MAC address. (The MAC address is a 12-digit string in this format: 000667xxxxxx. Refer
to the MAC address label attached to the PDU.) You may wish to request a long-term lease period for the

5-1

IP address, depending on your application. After you have discovered the IP address, skip Steps
through

5-6

and proceed directly to Step

6-1

.

2.3.2 Static IP Address Assignment

5-1 Determine IP Information: Before

assigning a static IP address, you'll need to know
the IP address, gateway address and subnet mask.
If you do not have this information, contact your
network administrator for assistance.

5-2 Configure Terminal Emulation Program:

Open a VT100-compatible terminal emulation
program (such as the HyperTerminal program
bundled with Microsoft

®

Windows®) on a

A

computer with an available DB9 serial port. (A
notebook computer may be the most convenient
choice.) Set the terminal emulation program to

A

use the COM port

that corresponds to the
computer’s DB9 serial port. Specify the
parameters B required to communicate with the
PDU terminal interface:

Bits per second: 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

included with the PDU to connect the PDU to
the computer. The circular connector A at one
end of the cable attaches to the 8-pin mini-DIN
serial port B on the PDU. (Align the connector
carefully to avoid damaging the pins.) The DB9
connector C at the other end of the cable
connects to the computer's serial port D.

5-4 Connect PDU to Network: While the PDU

is powered, connect a standard Ethernet patch
cable to the RJ-45 Ethernet port A on the PDU.

Note: This port is not compatible with PoE (Power over Ethernet)
applications.

5-5 Configure PDU in Terminal Mode: After

a brief pause, an initialization page should appear
in the terminal emulation program. Press any key
on the keyboard within 10 seconds to change the
PDU settings. (If the 10-second period has
elapsed, you can reboot the PDU by powering
down completely and then restoring power.)

4. Configuration and Operation

4.1 Automatic Transfer Switch

When the Primary and Secondary inputs are both connected to Tripp Lite UPS Systems, the PDU
operates as an Automatic Transfer Switch, providing redundant input power for high availability
applications. Under normal operating conditions, the PDU will distribute power from the Primary input
source, switching to the Secondary input source under certain conditions. The PDU will switch to the
Primary source whenever it is Good according to the PDU input voltage definitions (see below).

4.1.1 Preferred Configuration

The Automatic Transfer Switch function provides
increased availability when the Primary and
Secondary inputs of the PDU are connected to
separate Tripp Lite UPS Systems that are
connected to separate utility power sources. For
maximum availability, Tripp Lite recommends
using matching SmartOnline UPS Systems with
pure sine wave output for the Primary and
Secondary input power sources. The automatic
transfer switch function will be compromised if the
primary and secondary inputs are connected to the
same utility power source.

Warning: DO NOT connect the primary input
to a line-interactive UPS, due to transfer time
issues, or to any source that does not supply a
pure sine wave. Such sources may be used to
power the secondary input.

4.1.2 Automatic Transfer Switch Source Selection

Upon power-up, the PDU looks for a source ≥85V. If it is unable to find a source ≥85V, it remains off.

Input voltage definitions:
99V ≤ Vin < 139V Good

in

75V ≤ V
V

< 99V Fair

in

< 75V Bad

In normal operation (after power-up), if the selected source is no longer Good, the PDU will attempt to
switch to the other source, but only if the other source is Good. If the selected source becomes Fair and
the other source is not Good, the PDU will keep the loads connected to the selected source until the
selected source becomes Bad, at which point the loads will be disconnected (note that the source
selection doesn't change). After the loads are disconnected, they remain disconnected until the selected
source becomes ≥85V, or until the other source becomes Good.

4.1.3 Quick Test

After installing the PDU and connecting
equipment, you may test the Automatic Transfer
Switch function by temporarily shutting down the
UPS system connected to the Primary AC input.
When the Primary input UPS is no longer
supplying AC power, the PDU will switch from
the Primary input to the Secondary input, and the
Secondary input LED will illuminate. When the
Primary input UPS has been restarted and resumes
supplying AC power, the PDU will switch back to
the Primary input.

Note: The primary and secondary inputs must be connected to
separate sources of utility power. The automatic transfer switch
function will be compromised if the primary and secondary inputs
are connected to the same utility power source. Do not perform a
test with equipment that must remain in productive operation. Any
test procedure must prepare for the contingency that the equipment
may lose power. Do not test the PDU by detaching power cords
which are connected to live power sources, as this eliminates the
connection to ground and places your equipment at risk.
