Installing Chassis To The Rack - Seagate Exos E 4U106 Hardware Installation And Maintenance Manual

Figure 43 Adjusting middle slide ball bearing track

Installing chassis to the rack

WARNING! Safe handling precautions:
– Do not drop or lift the chassis using a mechanical lift while inner rails are engaged with middle rails.
The middle and inner rails should be properly aligned before engagement, so they glide smoothly
during the entire insertion.
– The 4U106 chassis must be entirely supported by the mechanical lift until the rails are locked in the
service position. Failure to do so can cause mechanical failure and serious personal injury.
– Do not push the chassis into the rack using the mechanical lift. The insertion force must be manual, and
unassisted by mechanical force or additional mass. Using the lift for this purpose could damage rails.
– Do not push the chassis into the rack using enclosure front panel as this may misalign or damage the
front panel. It is recommended to use the enclosure ears to push the enclosure back into the rack.
– Do not bend the middle rail in order to force alignment with the inner rail. Alignment should be
adequately established with the lift.
– If fine-tuning of alignment adjustments are required, do not adjust using the mechanical lift.
Adjustments should be made by shifting the chassis itself; not the lift, and not the middle rail.
– Lower the lift only after the service position is reached, and the rail is locked in place. Lower the lift by
no more than 2"– 3" while the chassis is inserted from the service position into the rack.
– The inner rails/chassis and the middle rails must be kept level, straight, and fully parallel during the
entire installation. Failure to comply can cause inadequate rail engagement, and possible damage to the
rails.
1. Extend the middle rail of both the left and right rail kit subassemblies roughly 3" beyond the face of the rack.
