Introduction
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 ships standard with a Network Management Card (NMC) in the box.
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.
Figure 2. UPS Network Management Card
The NMC has 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)
- Easy installation (can be installed while the UPS is online, which maintains the highest availability)
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.
Figure 3. Environmental Monitoring Probe
The EMP has the following features:
- Monitors temperature, humidity, and status of two user-provided contact devices/sensors
- Connects to an NMC through an RJ-45 CAT5 Ethernet cable (1 m cable 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
- Measures relative humidity between 10 - 90% with an accuracy of ±5%
- Temperature, humidity, and contact closure status can be displayed through a web browser
- Supports user-defined alarm thresholds for temperature, humidity, and contact closure status
- Events are stored in the NMC's event log
- Sends SNMP alarms to network management systems
- Sends e-mail notifications through SMTP
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 remote locations
- An ROO/RPO port to control power of the UPS unit through a wired remote switch

UPP software facilitates automatic, graceful shutdown of computers, servers, and network devices that are powered by a UPS, which saves all work-in-progress and ensures data integrity. UPP's user interface provides detailed information about connected servers and UPS units through USB and serial or network communication.
The UPP user interface is shown in the following figure.
Figure 13. UPP User Interface
The UPP software offers the following features:
- Helps avoid data loss by gracefully shutting down computers and virtual machines or servers that are powered by a UPS during an extended power outage
- Keeps servers running smoothly by automatically identifying hang-ups and rebooting the machine by using a watchdog capability
- Provides redundancy capability for dual-cord servers
- An easy-to-use web browser interface
- Communicates with the protected device directly (via USB or serial) or through the network (via NMC)
Supported servers
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
Supported rack cabinets
