sure that somebody is around for immediate assistance.
It should be handled with care to avoid dropping that may cause damage to the
product. Always use the correct lifting procedures.
Upon installation of the product:
Ambient temperature is very important for the installation site. It must not
exceed 30◦C. Due to seasonal climate changes; regulate the installation site
temperature making it not to exceed the allowed ambient temperature.
Before plugging-in any power cords, cables and connectors, make sure that the
power switches are turned off. Disconnect first any power connection if the power
supply module is being removed from the enclosure.
Outlets must be accessible to the equipment.
All external connections should be made using shielded cables and as much as
possible should not be performed by bare hand. Using anti-static hand gloves is
recommended.
In installing each component, secure all the mounting screws and locks. Make
sure that all screws are fully tightened. Follow correctly all the listed procedures
in this manual for reliable performance.

2.6.1 Disk Drive Installation
This section describes the physical locations of the hard drives supported by the
subsystem and give instructions on installing a hard drive. The subsystem supports
hot-swapping allowing you to install or replace a hard drive while the subsystem is
running.
NOTE: When the JetStor SAS 742JD is shipped, the disk trays are
not placed in the disk slots. If all disk trays will be used to install
all 42 disk drives, for quicker and easier installation of disk
drives in the JBOD subsystem, it is recommended to install first
each disk drive in a disk tray. After installing the disk drives,
insert 14 disk trays into one row of 14 slots at a time and lock
them one by one. Do the same for the next row until the last row.
