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
