15 Unseat and reseat any module whose LED is off. If LED does not
light after the module is reseated, replace the module.
16 Repeat step 15 until all module LEDs are on, then go to step 24.
17 Check power output on rear of power control panel for correct
voltage output to the shelf.
18 Is voltage to shelf correct?
M If yes, go to step 19.
M If no, go to step 23.
19 Check power input connection to shelf backplane for correct voltage.
20 Is input voltage to backplane correct?
M If yes, go to step 21.
M If no, go to step 22.
21 Problem exists in backplane power wiring. Resolve backplane fault,
then go to step step 24.
22 Fault exists in power leads from power control panel to shelf.
Resolve fault with power leads, then go to step 24.
23 Problem exists in power control panel. Resolve fault, or replace

2 Did the LED of the SDP-T module light?
M If yes, go to step 7.
M If no, go to step 3.
3 Turn the power switch of the SDP-T module off.
4 Unseat then reseat the SDP-T module.
5 Turn the power switch of the SDP-T module on.
6 Did the LED of the SDP-T module light?
M If yes, go to step 7.
M If no, replace the SDP-T module, then go to step 7.
7 Return to the SDP-T module power-up section of this chapter, and
continue SDP-T module power-up.
