6.3.1
Walking Path Inspection
Walking paths must be clear of obstructions and wide enough to allow passage of the enclosure to the site
where it will be unpacked. The following is a list of obstructions to consider when conducting a walking path
inspection:
• Cables - consider removing cables, including ramped cable covers, from the walking path before moving
the pallet. Leaving the cables in place creates a safety hazard for the installation team and can damage
the cables.
• Lift Locations - there may be locations along the walking path where the enclosure must be lifted in order
to proceed. Make sure that lift equipment is available at this location on the day of the delivery.
• Elevators - ensure that any elevators that will be required to lift the equipment to the data center/computer
room are rated to carry the full load of the enclosure plus passengers.

Airflow Consideration
Ensure that both the front and rear of the 4U60 G2 Storage Enclosure stay clear of any materials that may
block or disrupt the airflow in any way. Disrupting the airflow can cause the enclosure to overheat which may
affect performance or cause damage to the enclosure.
The following enclosure airflow principles should be considered for best results:
• Controlled air conditioners that are functional and can sufficiently maintain specified system operating
temperatures should be located in the facility where the system will be installed.
• The airflow in and out of the equipment must not be restricted.
