Single Power Supply or Commonly Powered Redundant Supplies

To activate a single power supply or commonly powered redundant supplies, place jumper JP1
(illustrated in Figure 3-1) on the SG2-LIDB in the vertical position (strand-mount installation).
Figure 3-6 illustrates this position. Power supplies #1 and #2 are both connected to the primary ac
power feed.

Individually Powered Supplies

To activate split ac powering of the node, place jumper JP1 on the SG2-LIDB in the horizontal
position (strand-mount installation). Figure 3-7 illustrates this position. Fuse jumper F7 must also be
removed. The primary ac power feed now connects to power supply #l and an independent
secondary ac source is connected to power supply #2. This configuration implies that the primary ac
power source originates from port
from port or port 3. For this configuration the optional interconnect cable (SG2-SIC) must be
OUT
installed between the lid board and the RF chassis.
