Statement 8:
CAUTION:
Never remove the cover on a power supply or any part that has the following
label attached.
Hazardous voltage, current, and energy levels are present inside any
component that has this label attached. There are no serviceable parts inside
these components. If you suspect a problem with one of these parts, contact
a service technician.
1. Ensure that the ac power switch is off on the power supply that you are
installing.
2. Install the power supply in the storage server, as follows:
a. Slide the power supply into the storage server. Make sure that the lever is
pulled straight out as you slide the power supply into the storage server.
b. Close the lever until the pull-ring latch locks in place. Make sure that the
lever locks into place in the storage-server chassis.
3. Wrap the strain-relief clamp around the power cord approximately 20 cm (8 in.)
from the power-supply connection end. Leave some slack between the clamp
and the power-supply end of the power cord.
4. Replace the power-supply nut and tighten it securely to secure the clamp to the
power supply unit.
5. Connect the power cord to the AC power connector. See Figure 69.
6. Plug the power cord into a properly grounded electrical outlet.
7. Turn on the power-supply switch.
