Replacing an AC Power Supply
Step 7 Loosen the captive screw at the front bottom of the power supply. See Figure 5-5.
Step 8 Move the supply slightly out, then reseat it and tighten the captive screw. This resets the supplys
internal power-monitoring circuit.
Step 9 Check the supply-monitoring circuit on the SCM. First, enter the resetcd 0 command at the control
terminal (this resets the power supply monitor on the SCM). After waiting about 10 seconds or more,
enter the dsppwr command and see if the FAIL indicator for the supply comes on again. Note which
power supply has failed.

Note If the DC and AC okay LEDS do not come on or the dsppwr command still indicates a failure,
proceed with the replacement.
Step 10 Loosen the captive screw that secures a supply to the power supply tray.
Step 11 Pull out the power supply with one hand on the handle and one hand under the supply.
