Single Power Supply or Commonly Po wered 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.

CA U T ION!

Take extreme care so that you do not directly connect primary and secondary power sources when implementing other configurations.
