T120 Library
Power Button Replacement
This guide provides instructions for replacing a power button in the T120
Library (referred to in these instructions as “the library”).
PREPARE FOR MAINTENANCE
Make sure that you address the requirements in this section to prepare for
the maintenance procedure.
Gather Tools and Supplies
You must have the following items to complete this procedure:
#2 Phillips screwdriver
Replacement power button from Spectra Logic (FRU PN 90949318)
Ensure ESD Protection
The repair environment for the library must be free of conditions that
could cause electrostatic discharge (ESD). To protect the library from ESD,
follow these procedures when repairing or testing the library:
Place a static protection mat on the work surface used while removing
and installing library components. Use a 1-megohm resistor to ground
the static protection mat.
Wear a static protection wristband or grounding footstrap whenever
you handle library components that have been removed from their
anti-static bags. Connect this wristband to the static protection mat or
to other suitable ESD grounding.
Keep all electronic components in anti-static bags when not in use.
