Figure 9-1: Internal 48V (or 38V) Line Power Module Location
Warning:
the 12V and the 48V (or 38V) Line Power Modules are closely similar in appearance. The
48V (or 38V) module is labeled ZWS30-48 (or ZWS30-38) on the large electrolytic capacitor.
Warning:
Connecting the 48V (or 38V) power supply to the 12V socket instead of the 48V/38V socket
may result in permanent damage to the main board.
If you look at the exposed SN2x00 chassis, you will see the motherboard and the 12V power module
that is already installed: see Figure 1. (The figures show the general arrangement of the chassis-
mounted components only, with little or no component details. The IC-4BRV card is omitted for
clarity). To the left of the existing 12V power module are two screw holes tapped into dimples, and
two smaller holes. These four holes are for mounting the 48V (or 38V) Line Power Module: see
Figure 9-1 and Figure 9-2.
