REPAIR AND REPLACEMENT INFORMATION
Warning: Ensure that DC input power is removed from the system before
performing any repair or replacement procedures.
Circuit Cards
Warning: Installation or removal of the circuit cards requires careful handling.
Before handling any circuit card, read and follow the instructions
contained on the Static Warning Page located at the beginning of this
manual. DC input power should always be removed from the circuit
card before inserting or removing the circuit card. To avoid possibility
of circuit card damage from static discharge, a static wrist strap
grounded through a one megohm resistor should always be worn when
handling the circuit cards.
When a trouble symptom is localized to a faulty circuit card, that particular circuit card
should be replaced in its entirety. No attempt should be made to troubleshoot or repair
individual components on any circuit card.
A circuit card can easily be replaced if a failure condition should occur. For circuit card
replacement, follow the procedures presented in this chapter.
DC input power should always be removed from the circuit card when inserting or
removing a circuit card. When a circuit card is removed from the system shelf, it should
immediately be placed in a static protective bag.
The terminal blocks located on the circuit cards can be removed by first loosening the two
screws, then gently pulling the terminal block body away from the circuit card. This
feature facilitates circuit card replacement.
Replacement Circuit Card Part Numbers
Refer to SAG586505000/SAG586505500 (System Application Guide) for replacement
part numbers. The SAG can be accessed via the CD (Electronic Documentation
Package) furnished with your system.
