1 About This Document
This document describes the procedure for replacing the power
supply used in MSA 1500 cs and MSA20 products, and EVA
4000/6000/8000 products.
NOTE:
Because this component is used in several products, the
drawings may reflect a different enclosure than the one you
have. The removal and replacement procedure is the same
for each product.
2 Before you begin
Observe the following precautions when replacing a power supply.
CAUTION:
Removing a power supply significantly changes the air flow
within the enclosure. Both power supplies must be installed
for the enclosure to cool properly. If a power supply fails,
leave it in place in the enclosure until a new power supply
is available to install.
If cabling is obstructing access to the power supply, carefully
move the cables out of the way to avoid loosening any
connections.
Parts can be damaged by electrostatic discharge. Use
proper anti-static protection. Refer to the documentation that
shipped with your system for additional information.
Have a copy of the product User Guide available for
reference. You can download a copy of the User Guide
from the product support page on the HP web site.
