Mounting the Internal 48V (or 38V) Line Power Module
Follow the steps described in Table 9-1 below to mount a 48V (or 38V) internal Line Power Module.
Step
Description
Step 1
Remove the 48V (or 38V) Line Power Module from its packing. Check that the side of the
largest electrolytic capacitor has the label ZWS30-48 (or ZWS30-38).
Step 2
Locate the plastic insulating foil over the four mounting holes in the SN2x00 chassis.
Step 3
Insert the plastic mounting studs into the Line Power Module, one into each of the two
corner holes that are on the opposite side to the finned heat sinks. Insert them from
below. See the upper picture in Figure 9-2 above.
Step 4
Locate the Line Power Module so that the studs pass through the holes in the plastic foil
and engage in the two chassis holes that are nearest to the front (LED) side of the
SmartNode. Press down gently to secure.
Step 5
From above, insert the screws into the module, one into each of the two holes at the
corners of the heat-sink side. Screw them home so that the screws pass through the foil
and secure the module onto the SmartNode chassis dimples. See the lower picture in
Figure 9-2.
Step 6
First insert the white 4-lead 48V (or 38V) supply cable in the Line Power Module’s
socket. Then connect it to the 48V/38V socket on the motherboard. You can not insert the
sockets the wrong way round. See Figure 9-2.
Step 7
Take the mains lead and insert the plug into the motherboard socket. This is adjacent to
the 230V external power socket. Insert the other end in the Line Power Module’s socket.
All plugs are polarized so that they cannot be inserted the wrong way round. Clip the
cable to the side of the chassis.
