2. Position the rack in the area of the customer's location where it will be installed.
|
3. Locate the physical area in the rack (which EIA units the drive will occupy).
|
Note: Because of the weight of the 3570, it is recommended that the 3570 be installed as low as
|
possible in the rack. Never install the drive so that the top of the 3570 is higher than EIA
|
unit 28 in the Netfinity Rack (9306900). There are no height restrictions in the NetBAY22
|
(9306200) rack.
|
The 3570 requires six EIA units on each side. Each EIA unit consists of three holes in the rack.
|
The supporting slides must be installed level in the rack. Figure 222 on page INST-36 and
|
Figure 223 on page INST-37 show the locations of the holes used.
|
4. It is necessary to remove the front door of the Netfinity rack to install the slide assemblies. This is
|
done by removing the hinge pins that hold the door to the frame.
|
Caution
|
Removal of the Netfinity rack door requires two people. One to hold the door while the other
|
removes the hinge pins. It is suggested that you remove the top hinge pin last.
|
Installing Supporting Slides and Tray in Rack
|
When installing the library models in a rack, six EIA rack units must be available. Make a copy of the
|
template Figure 221 on page INST-33. Use this template to assist you in the following steps.
|
1. Determine which rack location the 3570 will be installed in. Count and mark the six EIA units on
|
the left and right sides of the front and the rear of the rack.
|
2. Refer to Figure 222 on page INST-36 and install the four M6 caged nuts
1
, P/N 12J5288 and
|
four M6 X 12 socket button head screws,
2
, P/N 1621950, in the bottom EIA units on the left
|
side, as shown. Leave the screws loose enough to insert the slide mounting brackets
3
between
|
the screw heads and the EIA strips.
|
3. Read the notes below before continuing.
|
Notes:
|
a. Ensure that the slide is oriented so that when the inner slide is extended out, it extends toward
|
the front of the rack.
|
b. You will need an adjustable wrench to loosen the nuts holding the rear slide bracket to adjust
|
it to the width of the EIA units. The bracket fingers must go outside the EIA strips (the opposite
|
side of where the captive nuts are installed) for both the front and rear mounting points.
|
c. Do all of the adjustment with the rear mounting bracket. DO NOT loosen the front mounting
|
bracket screws.
|
4. Next, fit the left-hand slide assembly
4
as shown inFigure 222 on page INST-36 . Ensure that
|
the front and rear brackets
3
are flush to the EIA strips
5
on the opposite sides of where the
|
captured nuts
1
are installed. Tighten the nuts that hold the rear slide bracket.
|
5. Remove the left-hand slide assembly
4
and use that assembly to measure and adjust the
|
right-hand slide assembly that is attached to the tray assembly.
