Installation

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 through the PDU mounting brackets and into the mounting holes of the rack rail as shown.

1-2 0U Rack Mounting: Remove the screws

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 through the PDU mounting brackets and into mounting points in the rack

or rack enclosure.

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

Remove the screws 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 to a stable mounting surface by inserting two or more user-supplied screws through the PDU mounting brackets and into secure points on

the mounting surface.

2-1 Connect Input Plug Adapters (Optional -

Model 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.

2-2 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.

2-3 Connect PDU Input Plugs: Connect the

Primary input plug 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

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. See the Configuration and Operation section for more information.

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.

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.

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

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

5-14-1

which method to use, contact your network administrator for assistance before continuing the

installation process.

Dynamic IP Address Assignment

4-1 Connect PDU to Network: While the PDU

is powered, connect a standard Ethernet patch

cable to the RJ-45 Ethernet port on the 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,

4-1

depending on your network environment.

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 IP address, depending on your application. After you have discovered

the IP address, skip Steps through and proceed directly to Step .

6-15-65-1

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

computer’s DB9 serial port. Specify the parameters required to communicate with the

PDU terminal interface:

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

If the terminal emulation program supports multiple emulation modes, you may also need to specify VT100 emulation .

Network Operating Conditions

Configuration and Operation

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).

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 < V 75V < V V

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.

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.

Configuration and Operation

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.

Remote Monitoring and Control

The PDU provides remote monitoring , outlet

control and more via Web browser, telnet and SNMP-based Network Management Systems. For more information about configuration and operation of the PDU via the PowerAlert Web browser interface, refer to the SNMPWEBCARD User's Guide, included on the CD-ROM bundled with the PDU.
