Field Replaceable Units
Introduction
T1100 AS Application Server hardware systems are designed for the high-availability environments
required by telephony networks. They use redundant power supplies and many of the components
within a single T1100 AS chassis are redundant.
Even with the advanced reliability of the T1100 AS design, hardware failures may still occur. The
T1100 AS hardware is designed for easy maintenance when replacements are needed.
CAUTION: Always contact the Customer Care Center before performing any
troubleshooting or replacing components.
This chapter describes which T1100 AS hardware system components are field-replaceable units
(FRUs) and provides procedures for replacing them.
Note: This chapter does not describe how to diagnose which FRU may need to be replaced. For
diagnostic information, refer to the applications documentation.
CAUTION: Many of the procedures in this chapter require you to lower the front
fascia. Be sure you do not unplug the cable from the printed circuit board behind the
front fascia while opening the front fascia. Removing this cable from its connections
will cause the server to shut down.
Safety Information
Safety icons and text are used throughout Tekelec manuals to warn the reader of the potential of
personal injury, service interruption, and equipment damage. For information about what each
of the icons mean, see
Before beginning any procedure described in this manual, ensure that you are familiar with each
of the following safety admonishments. Additional safety admonishments may be included, or
repeated, for specific procedures.
TOPPLE: Always read and understand instructions completely before working on,
moving, raising or lowering the frame, any portion of the frame, or attachments to the
frame or equipment.
Never try to unpack any frame from the shipping container without at least two people to steady
any movement of the frame and related components. At least two people are required to safely
move and position any frame.
TOPPLE: Never pull out the shelf of any frame that is not anchored properly. Some
frames are required to be attached to overhead ladder racks before shelves are extended.
DANGER: No commercially AC powered equipment may be used or placed within
7 ft. of –48V equipment. AC powered equipment within 7 ft. of –48V equipment may
create a shock or current loop that can be severely hazardous to personnel and
equipment.
