Installing a Sun Disk Shelf
Use the following procedure to install a Sun Disk Shelf.
Starting at the bottom of the cabinet, locate the appropriate rack unit (RU)
height. Install Disk Shelves below controllers to prevent rack from tipping. The Sun
Disk Shelf requires four standard mounting units (4RU) of vertical space in the
cabinet.
| Caution -
This procedure requires a minimum of two people, or a mechanical lift, because
of the weight of the chassis. Attempting this procedure alone could result in
equipment damage or personal injury. Always load the heaviest equipment (disk
shelves) at the bottom of the rack.
|
Before You Begin
Extend all anti-tilt and stabilization devices from the bottom of the rack.
-
If you are using a universal 19-inch or Sun Rack II cabinet, snap an M6 square
cage nut into the 4U location where you will be installing the system. Install
in the top and bottom holes.
-
Install appropriate rail plates in four locations on the rack (2 front and 2
back) by aligning the two pins on the rail plate with holes on the cabinet
rails.
-
Insert M6 screws in the top and bottom holes of each rail plate and tighten (8
total places).
-
Install each rail by first aligning the front pins of the rack adapter plates
with corresponding holes in the front of the rail, then adjust the rail to fit
the rack and insert the pins from the rear rack adapter plates into the
corresponding holes of the rail.
-
Install four 8-32 screws into the four remaining front and rear holes of each
rack rail (16 total).
-
Using a mechanical lift or two people, one at each side of the shelf or
controller, carefully lift and rest the shelf on the bottom ledge of the left
and right rails. The following graphic illustrates the chassis insertion.
-
Carefully slide the shelf into the cabinet until the front flanges of the
shelf touch the vertical face of the rack.
-
Tighten the captive screws on each side of the front of the shelf to secure
the shelf to the rack.
-
At the back of the disk shelf, slide a system locking clip onto each lower
corner of the chassis.
