6. Connect the strip terminations of the harness wires to the -48 volt DC power supply.
7. Reinstall the clear plastic protector, ensuring that the harness wires come through the
hole in the bottom without obstruction. Tighten the two screws onto the spacers.
8. Turn on the circuit breakers to the -48 volt DC power supply.
9. Locate the power switch for the DC inlet you have selected, and turn the power switch
ON
by pushing it to
1
. The unit will begin power-up and system check immediately.
Warning:
If at a later time you need to access internal components, turn OFF
the unit and the -48 VDC power supply, and disconnect the harness from the
DC inlet on the SDM-9600 DC chassis to avoid electrical shock and damage to
the unit.
4.8.2 System Status on Power-up
On power-up the SDM-9606 blades execute program decompression, Signaling Engine
software load and system test.
You can follow the system status from the console (see next section), or by watching the
LEDs on the front of the blades. Table 4-1 shows the various LED states that occur during
SDM-9606 initialization sequence (after a power-on or software reset).
NOTE:
The entire startup sequence is executed within 30 seconds. Some of its stages
are brief, and may be difficult to distinguish from the rest..
