Eaton Bypass Power Module (BPM)
Power distribution unit for flexible infrastructure

Overview:

Eaton’s Bypass Power Module (BPM) is a combined maintenance bypass (MBP) and power distribution unit (PDU) for centralized UPS designs. By combining these two functionalities, the Eaton BPM increases reliability and flexibility while decreasing electrical installation costs. Compatible with Eaton’s 9170+, 9155 and 9PX UPS models, the BPM is an ideal solution for customers looking to achieve a flexible, fully-rackmounted IT environment.

Compatible with Eaton 9PXM, 9170+, 9155 and 8-10 kVA 9PX UPS models, the Eaton Bypass Power Module (BPM) acts as both a maintenance bypass and a panelboard. Providing you with increased flexibility, the BPM lowers upfront and electrical costs while protecting against downtime during maintenance. While a centralized UPS can provide value over distributed designs, power distribution and reliability become more critical. Because they are hardwired, UPSs over 6 kVA almost always require a maintenance bypass to directly connect utility power to the IT equipment.

In the event of scheduled UPS maintenance, a service event or failure, the Eaton BPM maintenance bypass functionality helps keep critical loads running. In addition, it enables you to distribute power from the UPS to connected equipment.

The need for maintenance bypass

While a centralized UPS can provide enormous value over distributed design, power distribution and reliability become more critical to the infrastructure plan. Because they are hardwired, UPSs over 6 kVA almost always require a MBP to provide a means of directly connecting utility power to IT equipment. MBP functionality helps keep critical loads running—even in the event of scheduled UPS preventive maintenance, a service event or failure.

Simplifying power distribution

In addition to a bypass, centralized systems also need a means to distribute over 6 kW of power from the UPS to connected equipment. This can pose additional challenges for both IT managers and their facilities teams. A traditional, centralized design may require a panelboard, wiring and conduit, not to mention the costs associated with electrical installation. Distribution can be even more complicated when installing the UPS next to—or inside of—an IT enclosure. By combining the MBP and PDU functionalities, the Eaton BPM not only improves system reliability and increases flexibility, but also drastically reduces electrical installation costs requiring this type of solution.

Improving flexibility and management

Unlike traditional MBP systems, a Bypass Power Module comes equipped with local outlets to enable an IT manager to add, remove or reconfigure PDUs throughout the lifecycle of the installation. This makes the infrastructure more apt to handle the addition of a new rack, a change of IT equipment with higher power ratings or the reconfiguration of enclosures to improve airflow than traditional, conduit-based designs. Integrating a BPM into an existing solution ensures an environment will be prepared for future growth and change.
