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

Product Guide

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.

Did you know?

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.

All 2U Rack or Tower UPS models except model 3KX come equipped with a communication bay for the
installation of an optional Network Management Card (46M4110). Model 3KX comes standard with a
Network Management Card (NMC) installed.

The NMC provides convenient, over-the-network UPS remote monitoring and management through a
standard web browser or UPS Power Manager software. Figure 2 shows the UPS NMC.

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 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

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

remote locations

An ROO/RPO port to control power of the UPS unit through a wired remote switch
