Did you know?
3U Rack or Tower UPS units feature Advanced Battery Management (ABM) technology that uses a unique three-stage charging technique that significantly extends battery service life and optimizes recharge time, compared to traditional charging methods.
3U Rack or Tower UPS units can enhance system availability with individual receptacle groups or load segments that can be programmed and controlled, which allows mission-critical devices to be prioritized during shutdown to preserve battery run time if there is a prolonged power outage.
3U Rack or Tower UPS units come standard with UPS Manager software that integrates seamlessly with the major virtualization platforms, which enables you to view and manage your entire power system from your current dashboard. It also triggers live migration during power outages and avoids data loss by gracefully shutting down virtual machines and hosts in a cluster if there is an extended power outage.

A UPS is a device that acts as a defensive barrier between electronic equipment and incoming power problems. It conditions, regulates, and filters out power disturbances to ensure a clean power source for IT equipment. A UPS also provides battery backup if there is a power failure.
In today’s high availability server environments, unplanned power outages or line quality irregularities can have a considerable financial impact on all sized businesses. The typical utility power is 99.9% available, but that means that there can be almost 9 hours of downtime a year, not to mention brownouts and other power quality problems. Selecting the right UPS can help protect against these potentially costly issues.
The RT5kVA and RT6kVA 3U Rack or Tower UPS units protect against power failures, power sags, power surges, under-voltage, electrical line noise, over-voltage, frequency variation, switching transients, and harmonic distortion.
The RT5kVA and RT6kVA 3U Rack or Tower UPS models offer the following features:
- High-efficiency protection delivers more real power (Watts) in a compact tower or 3U rack design, lowering power and cooling consumption
- A graphical Liquid Crystal Display (LCD) that provides intuitive configuration, management and monitoring capabilities in the following languages to reduce management complexity:
- Hot-swappable batteries for maximum uptime, availability, and ease of maintenance
- Standard UPS Power Manager software that provides effective local or remote power monitoring and management for servers and virtual machines, and allows for graceful remote system shutdown
- ABM technology that significantly extends battery service life and optimizes recharge time
- Load segments for individual control of receptacle groups to manage sequential shut downs and start ups and reserve battery run time for the most critical equipment
- Optional EBMs that provide extra run time to critical systems during a prolonged power outage
- Standard Network Management Card (NMC) for enhanced UPS monitoring and control over-the-network through a standard web browser
- An optional EMP for thermal management requirements (temperature and humidity)
- Dual channel communication through the USB or RS-232 port at the same time to maximize communications flexibility
- Remote flash upgradeable firmware for both the UPS and NMC, which makes it an ideal solution for remote locations
- An ROO and RPO port to control power of the UPS unit through a wired remote switch

The RT5kVA and RT6kVA 3U Rack or Tower UPS offerings are compatible with all ThinkSystem, System x and ThinkServer systems and other devices that require AC power.
To determine the best fit UPS for a particular configuration, the following needs to be considered:
- Total power load of the hardware that will be connected to the UPS
- Number and type of outlets required
- UPS outlet and group limitations for connecting the hardware to the UPS
To determine chassis, node and server overall power capacities, use the Power Configurator tool. The tool can be downloaded from http://support.lenovo.com/documents/LNVO-PWRCONF
To determine the power draw of other devices such as storage and switching that will be attached to the UPS, refer to the products user manual for the maximum power draw.
