NOTE
It is recommended that you pull the SPU from the back of the cabinet. This allows
you to monitor the cable movement to avoid snags and tangles with other SPUs or
cables.
The SPU should now be fully extended out the back of the cabinet.
WARNING Only extend one SPU at a time. Never attempt to extend more that one SPU
for any reason.
Step 4. Remove the Back Top Cover

a. Loosen the two captive screws along the back edge of the top cover.
b. Lift the back edge of the top cover up and away from the SPU
Step 5. Remove the Back Air Baffle

the system without the top cover and air baffle in place can make the system
susceptible to EMI problems.

b. Grasp the air baffle along the extruded handle on the back edge of the air baffle and lift it out of
the SPU.
