Section 4 — Maintenance
WARNING
The chassis weighs approximately 125 lbs. It should be moved only by two
persons or with the aid of some type of mechanical lifting device. Failure to
follow this precaution could result in injury or damage to the equipment.
6. Place a wheeled cart or some appropriate support in the front of the
power supply chassis to support it as it is removed.
7. Release the chassis from the rack by removing the screws at the front of
the chassis at the left and right hand lip. See Figure 4-1.
WARNING
If the equipment rack is not securely bolted down to the floor, do not extend
it on its mounting rails. The weight of the power supply chassis, when
extended on the mounting rails, is enough to topple the equipment rack if it
is not bolted down or otherwise supported. Failure to follow this precaution
could result in injury or damage to the equipment.
8. While guiding the heavy cables at the right rear through the cut-out in
the chassis, pull the chassis out on its mounting rails until they are fully
extended.
9. Release the chassis from the rails by locating and pressing the two
release buttons (one on each rail).
10. Using two persons or an appropriate lifting device, remove the chassis
from the mounting rails.
WARNING
If you are replacing a power supply in a system using a primary and a
redundant power supply, make sure the power supply units in the
replacement supply are of the same type (Pioneer or Todd) as the existing
supply. See
page 4-4
of this section for more information.
11. To reinstall the power supply or install a replacement supply reverse
the previous steps.
