Section C - Power Supply Replacement

Introduction

Removal and Replacement
There are no user-serviceable parts in the D9054 HDTV Encoder power supplies. If
one of the power supplies requires replacement, contact Cisco for information on
how to obtain a replacement power supply.
When removing a Tectrol power supply, remove the power cord from the defective
supply (LEDs will be off), loosen the latch screw and pull out on the handle at the
top of the power supply to remove it from the chassis.
To remove a Power-one power supply, remove the power cord from the defective
supply (LEDs will be off), loosen and then remove the screw in the lower left corner
of the power supply which secures the plate holding the power supply in place.
Then remove the plate and the pull out on the handle on the power supply to
remove it from the chassis.
When replacing power supplies, ensure that you replace each with the same model
number and manufacturer from the table below; both being the same.
Power Supply Manufacturer
Tectrol
Power-one
Important:
Note: Power supply replacement is the reverse of removal.
CAUTION:
The power supplies may be replaced while the D9054 HDTV Encoder is
functioning (i.e., they are hot swappable).
