Safety Precautions - HP D5970A - NetServer - LCII Installation Manual

Chapter 13
The HP NetServer rack mount kit requires seven EIA units of space in the rack.
Before mounting the server, plan the HP NetServer's location in the rack relative
to other rack components. Proper placement is vital both for safety and operating
efficiency. For more details, see the Rack Installation Road Map and the HP
NetServer LXr 8500 Rack Assembly and Cabling Reference Guide.
NOTE
If the HP NetServer is completely configured by the vendor
before delivery to the customer, then mounting the HP
NetServer in the rack may be the final step in the installation
procedure. If the vendor configures the HP NetServer at the
customer's site, installation of the network operating system
and other software may occur after the HP NetServer is
mounted in the rack.
CAUTION
The HP NetServer weighs over 155 pounds. To avoid
accidents, remove the HP NetServer's three power supplies
before lifting it.
If other rack components are to be mounted in the rack below
the HP NetServer, install those components before starting to
mount the HP NetServer.

Safety Precautions

Always keep the following safety and environmental issues in mind, especially if
you install the HP NetServer in a non-HP rack environment:
l
Optimum Operating Environment – The optimum operating
environment for the HP NetServer LXr 8500 is in an environmentally
controlled computer room with a temperature range of 20 to 22 C
(68 to 72 F) at 40 to 60% relative humidity.
Maximum Ambient Temperature – Ensure the maximum ambient
temperature does not exceed 35 C (95 F).
Elevated Operating Ambient Temperature. - The ambient operating
temperature within a closed or multi-unit rack assembly may exceed the
room's ambient temperature. Ensure the temperature within the rack itself
does not exceed 35 C (95 F).
Reduced Air Flow - As you mount equipment in the rack, ensure you
allow enough air flow for safe operation of the equipment. The HP
