For example, if a caution statement is labeled “D005,” translations for that caution statement are in the Systems Safety Notices
document under “D005.”
Be sure to read all caution and danger statements in this document before you perform the procedures. Read any additional safety
information that comes with the server or optional device before you install the device.
DANGER
Hazardous voltage, current, or energy levels are present inside any component that has this label attached. Do not open any cover or
barrier that contains this label.
(L001)
DANGER
To prevent a possible shock from touching two surfaces with different protective ground (earth), use one hand, when possible, to con-
nect or disconnect signal cables. (D001)

3
DANGER
When working on or around the system, observe the following precautions:
Electrical voltage and current from power, telephone, and communication cables are hazardous. To avoid a shock hazard:
•Connect power to this unit only with the IBM provided power cord. Do not use the IBM provided power cord for any other
product.
•Do not open or service any power supply assembly.
•Do not connect or disconnect any cables or perform installation, maintenance, or reconfiguration of this product during an
electrical storm.
•The product might be equipped with multiple power cords. To remove all hazardous voltages, disconnect all power cords.
•Connect all power cords to a properly wired and grounded electrical outlet. Ensure that the outlet supplies proper voltage and
phase rotation according to the system rating plate.
•Connect any equipment that will be attached to this product to properly wired outlets.
•When possible, use one hand only to connect or disconnect signal cables.
•Never turn on any equipment when there is evidence of fire, water, or structural damage.
•Disconnect the attached power cords, telecommunications systems, networks, and modems before you open the device covers,
unless instructed otherwise in the installation and configuration procedures.
•Connect and disconnect cables as described in the following procedures when installing, moving, or opening covers on this
product or attached devices.
To disconnect:
1. Turn off everything (unless instructed otherwise).
2. Remove the power cords from the outlets.
3. Remove the signal cables from the connectors.
4. Remove all cables from the devices.
To connect:
5. Turn off everything (unless instructed otherwise).
6. Attach all cables to the devices.
7. Attach the signal cables to the connectors.
8. Attach the power cords to the outlets.
9. Turn on the devices.
(D005)

4
DANGER
Uninterruptible power supply (UPS) units contain specific hazardous materials. Observe the following precautions if your
product contains a UPS:
•The UPS contains lethal voltages. All repairs and service must be performed only by an authorized service support representa-
tive. There are no user serviceable parts inside the UPS.
•The UPS contains its own energy source (batteries). The output receptacles might carry live voltage even when the UPS is not
connected to an AC supply.
•Do not remove or unplug the input cord when the UPS is turned on. This removes the safety ground from the UPS and the
equipment connected to the UPS.
•The UPS is heavy because of the electronics and batteries that are required. To avoid injury, observe the following precautions:
°Do not attempt to lift the UPS by yourself. Ask another service representative for assistance.
°Remove the battery, electronics assembly, or both from the UPS before removing the UPS from the shipping carton
or installing or removing the UPS in the rack. (D007)
CAUTION
Energy hazard present. Shorting might result in system outage and possible physical injury.
Remove all metallic jewelry before servicing. (C001)
CAUTION
Lead-acid batteries can present a risk of electrical burn from high, short-circuit current. Avoid battery contact with metal materials;
remove watches, rings, or other metal objects, and use tools with insulated handles. To avoid possible explosion, do not burn.
Exchange only with the IBM-approved part. Recycle or discard the battery as instructed by local regulations. In the United States,
IBM has a process for the collection of this battery. For information, call 1-800-426-4333. Have the IBM part number for the battery
unit available when you call. (C004)

1: OVERVIEW
Introduction
The IBM®3U Extend Run Battery Pack, for use with the IBM 5000XHV, 7500XHV and UPS 10000XHV uninterruptible power
supplies, provides extended load protection and extra security during the uninterruptible power supply battery replacement.
The IBM 5000XHV, 7500XHV and 10000XHV each support up to four 3U extend run battery packs. Extend run battery packs are
intended for either tower or rack-mount configuration. The 7500XHV and 10000XHV units are intended for rack-mount and tower
configurations. The IBM 5000XHV is intended for rack-mount configuration only.
Battery pack connectors on the IBM 7500XHV and 10000XHV are color-coded and keyed to prevent improper connection.
Battery pack connectors on the IBM 5000XHV are not color-coded or keyed. Refer to the Connecting Extend Run Battery Packs to the
Uninterruptible Power Supply section in this manual.
Refer to the Service section in the Uninterruptible Power Supply Operation and Setup Guide for battery replacement and service
information.
Attention:
•Read the Safety Instructions before installing the battery pack.
•The uninterruptible power supply and battery modules are heavy. Select a location sturdy enough to handle the weight.
•Refer to the Service section in this manual for information on how to obtain service and support for the unit.
Note: Illustrations in this document might vary in appearance from the purchased unit.
Inspect the unit upon receipt. Accidents and damage can occur during shipment. Notify the carrier and the IBM marketing
representative or authorized reseller if there is damage.
The packaging is recyclable. Save it for reuse or dispose of it properly.
The following tools will be needed for installing the extend run battery pack:
•Utility knife or scissors
•Two Phillips screwdrivers (#1 and #2)
•One wrench (10mm)
•Cage nut insertion tool or flat-blade screwdriver (for installing cage nuts in some rack cabinets)
