Figure 29 Direction to tighten crossbar thumbscrews

8. (Optional) For non-operating transport of the rack cabinet, complete the following steps:
a. Secure the crossbar by inserting and tightening an M5 screw just above each crossbar thumbscrew to a torque of
12 lbf-in (1.36N-m) to stabilize the rails against shock and vibration.
b. Return to the front of the rack cabinet.
c. Add an additional cage nut just below the former cage nut.
d. Insert and tighten two (2) Truss-head screws per side in the available screwholes within the 4U space just above
the top front mount bracket post to a torque of 12 lbf-in (1.36N-m). The screws secure the storage enclosure
against shock and vibration.
NOTE The crossbar screws you must use for non-operating transport prevent the enclosure from extension for service,
so only use them for their intended purpose, then remove them.

Install disk drives in the storage enclosure

Seagate provides carriers to protect each disk drive and connect each disk drive to the baseplane after vertical insertion
into a slot.
WARNING! Do not attempt to install the storage enclosure into the rack cabinet with disk drives preloaded in the
slots. Serious injury and damage could result. Unload any disk drives in storage enclosure slots to an static-protected
area. Do not further lighten the storage enclosure by removing other components.
CAUTION Make sure you are not connected to power at any time during installation procedures.
To install disk drives in the storage enclosure:
1. Facing the front of the enclosure, lower both pull handles and steadily pull the storage enclosure out on its rails until
it locks in the service position.
2. (Optional) As an extra safety measure while installing disk drives, continue to support the storage enclosure with a
mechanical lift to avoid any potential issues caused by downward forces.
