3. Installation

3.1 Mounting the PDU

The PDU supports 1U Rack configurations.
Note: 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.

3.1A

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.

3.1B Wall or 3.1C

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). Attach the PDU to a stable mounting surface by inserting two or more user-supplied screws
A through the PDU mounting brackets
B and into secure points on the mounting surface.

3. Installation (continued)

3.2 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
3.2 at the rear of the PDU (PDUMH15AT, PDUMH15ATNET, PDUMNH15AT1, PDUMH15ATS – IEC-320-C14 inlet; PDUMH20AT, PDUMH20ATNET, PDUMNH20AT1, PDUMH20ATS – IEC-320-C20 inlet).

3.2A To connect the Secondary input cord:

1. Form a loop in the Secondary cord
   A and 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.

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

3.2B Connect Input Plug Adapters (Optional – Models PDUMH20AT,

PDUMH20ATNET, PDUMNH20AT1, PDUMH20ATS 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.

3.2C 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.

3. Installation (continued)

3.2D 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. Installation (continued)

3.2E 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 will illuminate when the outlet is receiving AC power (this feature only applies to models with switchable outlets).

3.3 Networking the PDU (Only Applicable to Models with SNMP Network Card

Installed)

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
3.4A . If you will assign a static IP address to the PDU manually, go to Step
3.5A  If you are uncertain which method to use, contact your network administrator for assistance before continuing the installation process.

3.4 Dynamic IP Address Assignment

3.4A 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. The PDU will attempt to obtain an IP address via DHCP. This may take as long as several minutes, depending on your network environment.

3.4B 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
3.5A through
3.5F and proceed directly to Step 3.6A

3.5 Static IP Address Assignment

3.5A 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.

3.5B 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
A that corresponds to the computer’s DB9 serial port. Specify the parameters
B required to communicate with the PDU terminal interface:

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

3. Installation (continued)

3.5C Connect PDU to Computer:

Use the mini-DIN to DB9 serial cable (part number 73-1025) 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
.
3.5D 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.

.3.5E 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.)
Follow the sequence of responses below in order to assign an IP address to the PDU. The default terminal mode root password is TrippLite. Sample IP settings are shown – supply your own IP information when you configure your PDU.

Press A to Accept the settings, or M to Modify? M
Enter the root password: *****
Reset configuration to default values (Y/N)? N
For each of the following questions, you can press to select the value shown in braces, or you can enter a new value.
NETWORK INTERFACE PARAMETERS:
Should this target obtain IP settings from the network? [N] N
Static IP address [192.168.1.19]? 192.168.0.123
Static IP address is 192.168.0.123
Subnet Mask IP address [255.255.0.0]? 255.255.255.0
Subnet Mask IP address is 255.255.255.0
Gateway address IP address [192.168.1.1]? 192.168.0.1
Gateway address IP address is 192.168.0.1

You can also change the root password, real-time clock and other settings. (Tripp Lite recommends against changing the default settings unless you are an advanced user with a specific purpose.) After you have finished entering settings, the PDU will save changes to memory and reboot (this may take several minutes). After the PDU reboots, the initialization page should display the new static IP settings.

3.5FRemove Serial Cable: Remove the serial cable from the PDU and proceed to Step 3.6A

3.6 Testing Network Connection

3.6A Access PDU with Web Browser:

After an IP address has been assigned to the PDU, attempt to access it with a Web browser that supports frames, forms and Java™. Open a Web browser on a computer connected to the LAN and enter the IP address assigned to the PDU. You should be prompted for a password
A The user name is admin and the default password is admin. After you enter the user name and password, the PowerAlert Status page

B will appear in the browser window. For more information about configuration and operation of the PDU via the PowerAlert interface, refer to the SNMPWEBCARD User’s Guide, included on the CD-ROM bundled with the PDU.

5. Configuration and Operation

5.1 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).

5.1A 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.

5.1B 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
75V £ Vin < 99V| Fair
Vin < 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.

5. Configuration and Operation (continued)

5.1C 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.

5.2 Remote Monitoring and Control

The PDU provides remote monitoring
A, outlet control

B(see section 2. Feature Set Overview for models that support 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.
