Transportation Precautions
Improper transportation may damage equipment. Contact the manufacturer for precautions
before attempting transportation.
Exercise caution when transporting equipment.
l
The logistics company engaged to transport the equipment must be reliable and comply
with international standards for transporting electronics. Ensure that the equipment being
transported is always upright. Take necessary precautions to prevent collisions,
corrosion, package damage, damp conditions and pollution.
l
Transport the equipment in its original packaging.
l
If the original packaging is unavailable, package heavy, bulky parts (such as chassis and
blades) and fragile parts (such as PCIe GPUs and SSDs) separately.
