Figure 81. Fixing points: internal 48V (or 40V) line power module
Follow the steps below to mount a 48V internal line power module.
1. Remove the 48V line power module from its packing. Verify that the side of the largest electrolytic capaci-
tor has the label ZWS30-48.
2. Position the plastic insulating foil over the four mounting holes in the SmartNode 2300 chassis.
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 (see
figure 80
on page 117). Insert them from below.
4. Position 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.
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 Smart-
Node chassis dimples. See the lower picture in
figure 81
on page 118.
6. First insert the white 4-lead 48V supply cable in the line power module’s socket. Then connect it to the
48V socket on the motherboard. The plug is polarized so you cannot insert the sockets the wrong way
round. See
figure 81
on page 118.
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.
