Introduction; T1000 As Hardware System Frus - Tekelec T1000 Hardware Manual

Introduction

Introduction
Tekelec 1000 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 T1000 AS
chassis are redundant.
Even with the advanced reliability of the T1000 AS design, hardware failures may
still occur. The T1000 AS hardware is designed for easy maintenance when
replacements are needed.
CAUTION: Always contact Tekelec Customer Care Center before performing
any troubleshooting or replacing components.
This chapter describes which T1000 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.
