Servicing Frame Power Supplies
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.
7.
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.
8.
Release the chassis from the rails by locating and pressing the two release
buttons (one on each rail).
9.
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
of this section for more information.
10. To reinstall the power supply or install a replacement supply reverse the
previous steps.
