CHAPTER 2: INSTALLING THE <strong>D20MX</strong><br />
7.3. Connect the 20-pin header end of the cable (part number 975-1236) to<br />
connector P1 on the fiber optic daughter card.<br />
7.4. Secure the cable to the fiber optic daughter card with a cable tie.<br />
7.5. Insert the fiber optic daughter card partially into the chassis, and feed the other<br />
ends of the cable through the middle slot in the chassis wall between the VME<br />
slots and the peripheral slots.<br />
7.6. Connect the other end of the cable (with two connectors) to the <strong>D20MX</strong><br />
connectors J3 (shorter length of cable) and J4 (longer length of cable).<br />
See Figure 11, “Cable to fiber optic daughter card,” on page 34.<br />
Ensure that the cable is not pinched.<br />
7.7. Push the front panel of the fiber optic daughter card until it is fully inserted.<br />
7.8. Tighten the front panel retaining screws to 3.5 in-lbs to secure the fiber optic<br />
daughter card to the chassis.<br />
8. Install the new lower filler plate (part number 953-1015).<br />
9. Install the new filler plate (part number 953-1014) in the space above the <strong>D20MX</strong>.<br />
10. Attach any required communication cables to the connectors on the front panel of the<br />
<strong>D20MX</strong> or the backplane of the D20 chassis.<br />
11. If the <strong>D20MX</strong> is being installed in a VME chassis, connect the 0 V cable (part number<br />
975-1237):<br />
11.1. Connect the bare end of the cable wire to the O V connector on the WESTERM<br />
terminal block TB2-9.<br />
11.2. Remove the wire from the lower 0 V connector on the VME backplane and<br />
connect this wire to the male end of the 0 V cable.<br />
11.3. Connect the female end of the 0 V cable to the lower 0 V connector on the VME<br />
backplane.<br />
See Figure 12, “0 V cable connection”.<br />
12. Install the ferrite clamp if necessary.<br />
If you ordered a complete D20 system including the <strong>D20MX</strong>, notice that a ferrite clamp<br />
has already been attached to the power cable. Go to step 13.<br />
If you ordered a <strong>D20MX</strong> upgrade kit, a ferrite clamp included in the package is to be<br />
attached to the power inlet cable:<br />
12.1. Ensure that you are sufficiently grounded to prevent ESD damage to the<br />
<strong>D20MX</strong> or other components. See “Grounding the <strong>D20MX</strong>” on page 36..<br />
12.2. Remove ferrite clamp (<strong>GE</strong> part number 460-0073) from the package; handle<br />
with care as the magnetic material is fragile.<br />
12.3. Pass the power cable through the channel, approximately 15 cm (6 inches)<br />
from the connector on the chassis.<br />
12.4. Loop the power cable one more time around and through the core. See<br />
Figure 9.<br />
