•
Check if the rack-mounting brackets are properly secured to the pallet. The hold downs for HPE Infrastructure Racks are right-angled and sit
flush to the pallet and frame. Ensure that the bolt securing the bracket to the pallet is torqued to 16.9 N-m (150 in-lb.).
•
All racks should be secured in the trailer or truck in order to prevent a rack from falling on its side during vehicle turns.
Note
Since most common carriers are neither accustomed nor equipped to perform this function, this detail is particularly important, even if the
configuration is common carrier qualified.
Warning
To reduce the risk of personal injury or damage to the equipment, prior to shipping, remove all non-rack-mounted equipment, including any
component that is not mechanically fastened to the rack structure.
Special shipping considerations
Additional requirements for non-qualified components for shipment in an HPE Advanced Series Rack that is mounted on a shock pallet are listed
as follows:
•
Replace any wing nuts with hex or square-head nuts and appropriate locking hardware.
•
Inspect the rack for unsupported mechanical structures. Look for any cantilevered chassis with little or no rear support or any large chassis
with rails mounted to the extreme top or bottom of the chassis. Be especially attentive to any free movement of the component while mounted
in the rack. In some cases, it may be beneficial to use supplemental packaging materials to brace these components.
•
Do not ship backup media in either tape drives or in tape library units.
•
HPE UPS systems have been qualified for rack CTO. Each of these UPS systems may be shipped in a rack, provided the system is electrically
disconnected from the battery during shipment; each unit comes equipped with the appropriate isolators to comply with this requirement.
•
Some shipping regulations require specific identification of the batteries enclosed with the package. For example, the U.S. Department of
Transportation requires a pack enclosing a UPS battery be marked to indicate when a spill-proof lead acid battery is enclosed. For CTO rack
shipments destined for Europe, specific markings of all battery systems are required, including the NiCad label for the real-time clock batteries
found in each server.
Warning
When reinstalling the battery, a spark may be observed at the time of reconnecting the spade terminals. Be sure to hold the connectors by the
insulated housing. To prevent rotation of mounting rails, ensure that the front panel mounting screws are in place when reinstalling the battery.
Door height clearances
HPE does not advocate tipping loaded racks to navigate height-restricted doorways. The HPE recommended procedure is to first depopulate the
rack and then tip the rack to pass the restricted doorway. Once the rack is positioned in its final location, it can be repopulated. This will enable
the rack to maintain stability by not tipping a heavily loaded rack. Depopulating the rack also helps ensure that the integrity of the components in
the rack is not compromised by tipping.
If you have restricted height doorways, you have several alternatives for purchasing HPE factory racked solutions that can accommodate the
height of the doorways without the need to depopulate the rack.
If you have restricted doorways:
•
You can order racked solutions in an appropriate sized rack that can be accommodated by the doorways. Choose the rack size that best meets
your data center needs and is able to pass all doorways on the path to the racks’ final location.
•
For a fully loaded 42U rack that is unable to pass through the doorway, options include:
•
Ordering an empty 42U rack and purchasing installation services from HPE Services.
