Holding both assemblies together, carefully place the unit upside down, preferably on a soft surface to
prevent scratching or other damage.

Make sure the screw holes in the metal chassis align with the screw mountings in the top cover
moulding.
CAUTION
When replacing the front cover, do not over-torque the screws. Excessive torque may damage the plastic
screw mountings.

Drive in the six screws that hold the front cover and chassis assemblies together using a T-10 Torx
driver.
Changing Fuses
There are two versions of power supply, the Celestica version (earlier build), and the Frei version (later
build).
There are two field-replaceable fuses located in the power supply. They are of type T1.6A.
In the
photographs that follow in this section, the MIF and receiver boards are removed for clarity, but the
power supply cover can be removed with the boards in place.
To gain access to the fuses:

Remove the top cover assembly (see page 28).
