2-4, STORAGE
ENVIRONMENT
The 41951A may be stored or shipped under the following environmental conditions.
Temperature
-40°С to 70°C

2-5. PACKING
Original Packing.
Containers and packing material identical to those used in factory packaging are available
from Hewlett-Packard.
If the unit is being returned to Hewlett-Packard for servicing, attach a
tag indicating the type of service required, return address, model
number
and full serial
number.
Other Packing.
The following general instructions should be used for repacking with commercially available
materials:
a. Wrap the unit in heavy paper or plastic.
If shipping to a Hewlett-Packard Sales Office
or Service Center, attach a tag indicating the type of service required, return address,
model number and the full serial number.
b. Use a strong shipping container.
A double-walled carton made of 350 pound test
material is adequate.
c. Use enough shock absorbing material ( a 3 to 4 inch layer ) around all sides of the
unit to provide a firm cushion
and to prevent the unit from moving
inside the
container.
d. Seal the shipping container securely.
e. Mark the shipping container FRAGILE to ensure careful handling.
f. In any correspondence, refer to unit by its model number and the full serial number.
NOTE
if you ever need to return the 41951A for servicing, HP recommends that you
return your 4195A also so that system performance can be verified after repairs
are made.
