is receiving power. If the lights do not illuminate, check the following:
●Incoming power sources
●Power cable connections to the power sources and cabinet
●The polarity of the power cables. See Figure 2.10 for power-cable polarity information; for additional electrical wiring information, see Appendix A of the DNCP Series 400/400-CO(PA-8500): Site Planning Guide (R454).)
Figure 2.10. DC Connector Cable/Cabinet End
If the power cable or the power source is not the cause of the problem, refer to the FTX Operating System: DNCP Series
400/400-CO (PA-8500) Operation and Maintenance Guide (RXXX) for further system troubleshooting.
2.1b.2 Installing the Power Cables (Bottom Entry)
Perform the following steps to route the power cables from the bottom of the system.
1.Unpack the two power cables (AW-000955 and AW-000968) from one of the cartons shipped with the system. The part number for each power cable appears on the cable and on the plastic bag in which the cable is shipped.
Before connecting a power cable, always shut off both MAIN system power switches.
Route the power cables up through the cable guides provided on the chassis frame.
2.Connect each color-coded power cable to the cabinet and into a separate DC power source (See Figure 2.11) . To connect the power cable to the cabinet, align the red mark on the cable with the red alignment guide at the top of the connector. Then, twist the cable clockwise until the red mark is aligned with the alignment guide on the right side of the connector.
The power cables are color-coded (red and blue) to match the color-labeling of the power sources at your site.
Be sure to connect each power cable to a separate DC power source . If they are plugged into the same source, a failure at the source will result in a system crash.
