use the following procedure to install a power supply:

    step 1 check that the power switch on the power supply is in the off position.

    step 2 align the power supply with the chassis bay, and slide it in until the center hole (between the captive screws) is aligned with the hole in the bay's lower shelf. (see figure 6-1.)

    step 3 tighten the two captive screws that secure the power supply in the chassis bay, using the phillips or flat-blade screwdriver. (see figure 6-1.)

    step 4 connect the power cord to the replacement power supply.

    the power cord connector can be inserted in the power socket only when the captive screws are tightened. this prevents hot swapping of live power supplies.

    step 5 turn on power to the replacement power supply.

    step 6 check that the led on the power supply is green. (see figure 6-1 for the location of the power supply led.)

    step 7 check that the power supply led (ps1 or ps2) on the front panel is green. (for an explanation of power supply leds, see table a-3.)
