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
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.
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 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.
A |
4-1 |
4-2 Discover IPAddress: 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 5-1 through 5-6 and proceed directly to Step 6-1 .
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 A 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 |
If the terminal emulation program supports multiple emulation modes, you may also need to specify VT100 emulation C .

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 |
< 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.
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.

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.
Primary Input Active |
Secondary Input Active |
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 A , outlet control B 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.
