2-6 Installing and Connecting the Protection Switch DXC-100PSX
7. Insert the “-48 volt supply” wire into the negative terminal clamp and tighten
the clamp screw.
8. Insert the “return” wire into the positive terminal clamp and tighten the
clamp screw.
9. Insert the power terminal block into the mating receptacle on the rear panel
(see
8 Figure 2-5 ).
10. Repeat Steps 2 to 9 if the DXC-100PSX has a second (redundant) DC Power
Supply Module installed.
11. To minimize disturbance to the wires through casual contact, secure the
power cables to the rack frame using multiple cable ties. The first tie should
be located within 6 inches of the terminal block.
12. Power up both the DXC-100 and N+1 Protection Switch. The LED on the PSX
Controller Module will flash as the unit powers up, loads software, and runs a
self-test. This will take a few minutes, depending upon how many modules
have been configured.
13. Once the system is powered up, you should see a flashing Green
READY LED
on the N+1 Protection Switch Controller module; a solid Green
READY LED on
the online DSMC.2; and a flashing Green
READY LED on the Standby DSMC.2.
Ignore any alarms at this point.
