Chapter 5. Hardware maintenance information
This chapter contains information about IBM customer replaceable units (CRUs)
and field replaceable units (FRUs) for the uninterruptible power supply and
instructions for replacement parts that are not installed during a typical installation.
Replaceable uninterruptible power supply components
Replaceable components are of three types:
v Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your
responsibility. If IBM installs a Tier 1 CRU at your request, you will be charged for
the installation.
v Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or
request IBM to install it, at no additional charge, under the type of warranty
service that is designated for your uninterruptible power supply.
v Field replaceable unit (FRU): FRUs must be installed only by trained service
technicians.
For
information about the terms of the warranty and getting service and assistance,
see Appendix A, “Getting help and technical assistance,” on page 43 and
Appendix B, “IBM Statement of Limited Warranty Z125-4753-08 04/2004,” on page
45.

Uninterruptible power supply and battery care
For the best preventive maintenance, keep the area around the uninterruptible
power supply clean and dust-free. If the atmosphere is very dusty, clean the outside
of the system with a vacuum cleaner. For full battery life, keep the uninterruptible
power supply at an ambient temperature of 25°F (77°F).
