RT8kVA and RT11kVA 6U Rack or Tower
Uninterruptible Power Supplies

Product Guide

The RT8kVA and RT11kVA 6U Rack or Tower Uninterruptible Power Supply (UPS) offerings provide
extended power protection with increased efficiency and simplified power management to safeguard high­availability of System x® and ThinkServer® server environments. With efficiency ratings of up to 98%,
these compact 6U rack or tower designs can help reduce energy usage without compromising
performance or reliability.

The 6U 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 6U Rack UPS unit (RT8kVA or RT11kVA) is shown in Figure 1.

Did you know?

6U 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.

6U Rack or Tower UPS units come standard with the Maintenance Bypass module, which enhances
system availability by providing service continuity during UPS maintenance and upgrades.

6U 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.

All 6U Rack or Tower UPS models come standard with a NMC installed. The NMC provides convenient,
over-the-network UPS remote monitoring and management through a standard web browser or UPS
Power Manager UPM software. Figure 2 shows the UPS NMC.

Figure 2. UPS Network Management Card

The NMC includes the following features:

Versatile connectivity through HTTP, SNMP, SMTP, Telnet, SSL, and SSH

Simultaneous shutdown of protected servers

Configuration of automatic email messages in response to UPS alarms and to transmit reports

Customizable actions, including automatic shutdown if there is an extended power failure with
standard UPS Power Protector software

Control of UPS on/off switching with a web browser

Adjustment and control of load segments through the HTML interface, including sequential starting
of the installation and optimization of backup time by shutting down non-priority systems

Automatic date and time adjustment through an NTP server

Dual stack IP v4/IP v6

Recording of events and measurements in the card log

Data and event logging in the nonvolatile memory

Card firmware update through the network

10/100 Mb Ethernet (RJ-45 connector) with auto-negotiation

Measurement of humidity and temperature with the optional Environmental Monitoring Probe (EMP)

An optional EMP (part number 46M4113) is used to report local temperature and humidity values and make
that information available to management tools. The EMP connects to the UPS via the NMC. The EMP is
shown in Figure 3.

Figure 3. Environmental Monitoring Probe

The Environmental Monitoring Probe has the following features:

Monitors temperature, humidity, and status of two user-provided contact devices or sensors

RT8kVA and RT11kVA 6U Rack or Tower Uninterruptible Power Supplies 3

Connects to an NMC through an RJ-45 CAT5 Ethernet cable (1 m cable that is included with the
EMP)

Can be located up to 20 m (65.6 ft) from the UPS

Measures ambient temperatures between 0 - 80 °C (32 - 176 °F), with an accuracy of ±1 °C (33.8°
F)

Measures relative humidity between 10 - 90%, with an accuracy of ±5%

Displays temperature, humidity, and contact closure status through a Web browser

Supports user-defined alarm thresholds for temperature, humidity, and contact closure status

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
