SUMMARY STEPS
1.
Ensure that the unistruts are installed. See the Steps, on page 4.
2.
Attach the rear vertical cable troughs —one right and one left—to the rear of the chassis (as shown in the
figure below) by i nserting the 10 M4x14-mm flat head screws (5 on each side) and using the screwdriver
to fasten the screws to attach the cable troughs firmly to the chassis.
3.
If applicable, remove blank covers and install cable pass-through accessory plates.
4.
Remove the blank plates by unscrewing the four screws on each one. See the figure below.
5.
Attach the inner cut-out plates, as shown in the figure below, using the four screws provided. See the
figure Inner Cut-out Plate—Fixed Configuration Power Shown.
6.
Attach the outer cut-out panel using the screws provided. See the figure below.
7.
Attach the rear upper horizontal cable guides (see the figure below) by inserting five longer Phillips screws
through the holes in the face of the brackets and into the chassis and tightening them to the chassis with
the screwdriver.
8.
Insert the four short Phillips screws (two on each side) that attach the bracket to the vertical cable trough
support flange and tighten them to the troughs with the screwdriver.
9.
Attach the rear mid-chassis horizontal cable guide and strike tube (see the figure below) by inserting the
five longer Phillips screws through the holes in the face of the brackets and into the rear (OIM) side of
the chassis and tightening them to the chassis with the screwdriver.
10.
Insert the four short Phillips screws (two on each side) that attach the bracket to the inside of the vertical
cable troughs, and tighten them to the troughs with the screwdriver.
11.
Attach the rear lower horizontal cable guides (see the figure below) by inserting four longer Phillips screws
through the holes in the face of the brackets and into the chassis and tightening them to the chassis with
the screwdriver.
12.
Insert the four short Phillips screws (two on each side) that attach the bracket to the vertical cable trough
support flanges and tighten them to the troughs with the screwdriver.
13.
Attach the rear upper grille by carefully hooking the tabs on the top of the grille over the hook supports
on the top of the vertical cable troughs (see the figure below).
14.
Press the grille firmly against the grille support until it snaps onto the ball stud snaps on the rear (OIM)
side of the chassis.
15.
Attach the rear lower bezel by carefully inserting the tabs on the grille into the hook hanger brackets on
the lower bezel frame. Press the grille firmly against the grille frame until it snaps onto the ball stud snaps
on the rear (OIM) side of the chassis (see see the figure below).
16.
Orient the doors so that the keyhole slots are pointing up.
17.
Align the doors vertically in their appropriate positions so you can determine where to thread the first two
screws that are adjacent to the keyholes. See the figure below. Set the doors aside, and thread the two
screws.
18.
Place the doors on the screws in the keyhole positions, two for each door.
19.
Insert four M4x8-mm wafer-head screws (two on each side) into the appropriate screw holes in the doors,
and use the screwdriver to fully tighten.
20.
Insert and fully tighten all screws.
21.
Ensure that the doors are properly aligned.
