A maximum of 100 mm (3.94 in) cabling space is available if you install an air filter door kit for a device. To use copper or twisted pair cables (which are thick) to connect the ports on the device, make sure routing these cables does not interfere with the installation or use of the door kit.

Installation tools

The following installation tools are not provided with the door kit. Prepare them yourself.

· Phillips screwdriver.

· Flat-blade screwdriver.

· ESD wrist strap.

To facilitate the door kit installation, prepare screwdrivers with the shaft length greater than 150 mm (5.91 in).

Installing the door kit

Installing the door kit for an S12516X-AF/S12516F-AF, S12512X-AF/S12512F-AF, S12508X-AF/S12508F-AF, CR19000-16, CR16016-X, or CR16008-X device

IMPORTANT:

As a best practice, complete the installation of cards before installing the door kit.

Installing brush filters

Brush filters are attached to the chassis through cable management brackets.

To install brush filters:

1. Attach brush filters to the cable management brackets, as shown by callout 1 in Figure 2.

Make sure space exists between the clamp of a brush filter and its attached cable management bracket so that slight moves between the two are allowed.

You do not need to attach brush filters to the bottom cable management brackets.

2. Attach the cable management bracket with the right brush filter to the right side of the chassis and the cable management with the left brush filter to the left side.

The right brush filter has an "R" mark. The left brush filter has an "L" mark.

3. To avoid interfering with the subsequent installations, comb the brush filters outwards.

Attaching MPU air filter to the top hood

Before installing the top hood on the device, attach the MPU air filters to the top hood.

To attach MPU air filters to the top hood:

1. Place the top hood on a flat surface upside down.

2. Fit the bottom of each side pate into the grooves on the top hood, as shown by callout 1 in Figure 3.

3. Use two M3 countersunk-head screws to secure each MPU air filter to the top hood, as shown by callout 2 in Figure 3.

Figure 3 Attaching MPU air filters to the top hood

Installing the top hood and bottom plate

Installing the top hood

1. Align the three installation holes in the top hood with the installation holes in the chassis.

2. Insert an M3 pan-head screw through an installation hole in the top hood into the installation hole in the chassis. Turn the screw part way into the installation holes. See callout 1 in Figure 4.

3. Perform the same procedure to insert M3 pan-head screws into the other two installation holes, as shown by callouts 2 and 3 in Figure 4.

4. Fasten all the screws.

5. Slide a brush filter onto each air filter along the groove, as shown by callout 4 in Figure 4.

Installing the bottom plate

1. Align the four installation holes in the bottom plate with the installation holes in the chassis.

2. Insert an M3 pan-head screw through an installation hole in the bottom plate into the installation hole in the chassis. Turn the screw part way into the installation holes.

3. Perform the same procedure to insert M3 pan-head screws into the other three installation holes.

4. Fasten all the screws.

Cabling

Route the card cables before installing the door jambs.

· Route the MPU cables through the round holes in the MPU air filters.

· Route the service module cables through the brush filters at the two sides of the service module slots.

Re-comb the brush filters after completing cabling to ensure dust prevention.

Figure 6 Routing cables

Installing the jambs

The left and right jambs are different in structure. The right jamb has an "R" mark. The left jamb has an "L" mark. Identify the left and right jambs before installation.

To install the jambs:

1. Fit the top and bottom of a jamb into the grooves on the top hood and bottom plate, respectively, as shown by callout 1 in Figure 7.

2. Use M3 countersunk-head screws to secure the jamb, Fasten screws on the top hood and bottom plate first and then on the MPU slot air filters, with two screws on each plate. See callouts 2 to 4 in Figure 7.

3. Perform the same steps to install the other jamb.

Figure 7 Installing a jamb

Installing the left and right doors

1. Place the right door vertical to the front panel of the device and close to a jamb.

2. Tilt the door slightly to ensure that the lower hinge pin on the door aligns with the hinge hole on the jamb. Insert the pin 3 mm (0.12 in) into the hole. See callout 1 in Figure 8.

3. Use the upper hinge on the jamb to press down the spring tab on the door and insert the upper hinge pin on the door into the hinge hole on the jamb. See callouts 2 and 3 in Figure 8.

4. Move the door slightly down to insert the two pins completely into the hinge holes.

5. Perform the same steps to install the left door.
