RT1.5kVA, RT2.2kVA and RT3kVA 2U Rack or Tower Uninterruptible Power Supplies

The RT1.5kVA, RT2.2kVA, and RT3kVA 2U Rack or Tower Uninterruptible Power Supply (UPS) offerings provide extended power protection with increased efficiency and simplified power management to safeguard the high-availability of Lenovo server environments. With efficiency ratings of up to 99%, these compact 2U rack or tower designs can help reduce energy usage without compromising performance or reliability.

The 2U Rack or Tower UPS units can be installed in a data center rack cabinet or can be used as tower UPS units in office and distributed IT environments where extended power protection is required.

The 2U Rack UPS unit with the Extended Battery Module is shown in Figure 1.

2U 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.

2U 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.

2U Rack or Tower UPS units come standard with UPS Power 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 incidents.

The RT1.5kVA, RT2.2kVA and RT3kVA 2U Rack or Tower UPS units are most effective against power failures, power sags, power surges, under-voltage, and over-voltage.

The RT1.5kVA, RT2.2kVA and RT3kVA 2U Rack or Tower UPS models offer the following features:

• High-efficiency protection for more real power (Watts) in a compact tower or 2U rack design, which lowers 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:
  • English
  • French
  • German
  • Spanish
  • Russian
  • Portuguese
  • Italian
• 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 external battery modules (EBMs) that provide extra run time to critical systems during a prolonged power outage
• An optional 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 and an optional NMC at the same time to maximize communications flexibility
• The USB port supports HID (Human Interface Device) Power Device Class which means that the UPS can be directly managed by operating systems that support such USB classes.
• Remote flash upgradeable firmware for the UPS and NMC, which makes it an ideal solution for remote locations
• An ROO/RPO port to control power of the UPS unit through a wired remote switch

The 2U 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

The 2U Rack or Tower UPS units can be installed in the compatible rack cabinets as listed in Table 8.
