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
IN, port 1 or port 2. The secondary ac power source originates
from port
OUT or port 3. For this configuration the optional interconnect cable (SG2-SIC) must be
installed between the lid board and the RF chassis.

Other power configurations are possible, but not recommended.
CAUTION!
Take extreme care so that you do not directly connect primary and secondary power
sources when implementing other configurations.
