Features

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 RT8kVA and RT11kVA 6U Rack or Tower UPS units protect against the following power problems: power failures, power sags, power surges, under- voltage, electrical line noise, over-voltage, frequency variation, switching transients, and harmonic distortion.

The RT8kVA and RT11kVA 6U Rack or Tower UPS models offer the following features:

• High-efficiency protection delivers more real power (Watts) in a compact tower or 6U rack design, which lowers power and cooling consumption
• Graphical Liquid Crystal Display (LCD) provides intuitive configuration, management, and monitoring capabilities in the following languages to reduce management complexity:
  • English
  • French
  • German
  • Spanish
  • Russian
  • Portuguese
  • Italian
• Hot-swappable batteries for maximum uptime, availability, and ease of maintenance
• Standard UPS Power Manager software provides effective local or remote power monitoring and management for servers and virtual machines, and allows for graceful remote system shutdown
• ABM technology significantly extends battery service life and optimizes recharge time
• Optional external battery modules (EBMs) provide extra run time to critical systems during a prolonged power outage
• Standard NMC provides enhanced UPS monitoring and control over-the-network through a standard web browser
• Optional Environmental Monitoring Probe provides thermal management requirements (temperature and humidity)
• Standard Maintenance Bypass enhances availability by providing service continuity during UPS maintenance and upgrades
• Provides dual channel communication through the USB or RS-232 port and an NMC at the same time to maximize communications flexibility
• Flash upgrades firmware for both the UPS and the NMC, which makes it an ideal solution for remote locations
• Includes ROO and RPO connectors to control power of the UPS unit through a wired remote switch

Supported servers

The RT8kVA and RT11kVA 6U 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.

For additional technical information on the UPS line cords, outlets and grouping refer to the UPS Technical Reference, https://support.lenovo.com/docs/UM104477

Supported rack cabinets

The RT8kVA and RT11kVA 6U Rack or Tower UPS units can be installed in the compatible rack cabinets that are listed in Table 4.
