7. Field Replacement Procedures
Chapter 7 explains how to replace a major component in the field. The
procedures apply to the replacement of a failed component or to the
installation of a new upgrade. To replace a component in the field, follow
these basic steps:
1. Turn the instrument off.
2. Remove the instrument cover (page 7-2).
3. Turn the instrument on and perform a visual check to identify the
faulty component (page 7-5).
4. Turn the instrument off and remove the power cord.
5. Replace the component.
6. Replace the cover, plug in the power cord and turn the instrument on.
7. Verify that the replacement solves the problem (page 7-26).
The replaceable components in the F6150 are:
• Instrument front panel (page 7-5)
• Communications board (page 7-13)
• Circuit boards in slots 1 through 11 (page 7-17)
• Battery simulator (page 7-19)
• Cooling fans (page 7-22)
Preparatory Steps
The replacement of any component in the F6150 requires removal of the
cover first. If the cause of a problem is undetermined at the time the
cover is removed, turn the instrument on and check the components
visually. When the faulty component is identified, follow the
replacement procedures in this chapter.
