76 REMOVAL AND REPLACEMENT PROCEDURES
Top Cover
NOTE It is unnecessary to remove the top cover for most removal or replacement procedures.
1 Disconnect power from the system (page 68), remove the access panel (page 74), and remove the
front bezel (page 75).
2 Push a flat screw driver into tab 1 on the rear of the chassis and gently pry the cover upward.
3 Push the top cover toward the back of the chassis and lift up.
Hood Sensor (Smart Cover Sensor) (Optional)
To remove the hood sensor:
1 Disconnect power from the system (page 68), remove the access panel (page 74), and lay the
workstation on its side with the system board facing up.
2 Disconnect the white 1x3 hood sensor connector from the inline connector attached to the front panel
harness.
3 Slide the hood sensor forward.
CAUTION Be careful when sliding the hood sensor forward. The hood sensor bracket and the chassis
contain sharp edges that present a safety hazard.
