Appendix B. Hardware maintenance procedures

Removing the logic unit to install parts

Read Safety notices, and “Handling static-sensitive devices” on page vi before continuing.

1.

Turn off the power supply switch

.

 

2.

Disconnect all cables from the thin client.

 

3.

Hold the thin client cover assembly, lift latch

, and

 

pull the logic unit

out.

 

 

4. Carefully lay the logic unit down with the internal components facing up. You are now ready to perform the installation procedures provided in this chapter.

5.Complete the procedure, “Reassembling the thin client”

when you are finished installing components in the logic unit.

Reassembling the thin client

Read Safety notices, and “Handling static-sensitive devices” on page vi before continuing.

1.To reassemble the thin client, carefully slide the logic

unit

into the cover assembly while depressing the

slide stop

.

2.Slide the logic unit completely into the cover assembly,

until the latch
