It is important for you to understand the structure of your Netfinity rack. For the purposes of installing a 3570 library, familiarize yourself with the EIA strips. These strips are used to denote groupings of three holes each which, in turn, are numbered. Each group of three holes is called anEIA unit. Six EIA units must be available to install a 3570 library; within those six EIA units, the slide will be mounted to the bottom EIA.
__ Step 1. To prepare for this task, and all successive tasks, refer to the parts shown in Figure 35 on page 79. The tools you will be using to install the 3570 include: a flat blade screwdriver, a number two Phillips
screwdriver and an adjustable wrench. Two hex wrenches are included in the machine package.
__ Step 2. Determine in which rack location the 3570 will be installed; count six EIA units to accommodate for its height and mark the lower EIA units on the right and left sides in the front and rear of the rack. These EIA units identify the base upon which you will be developing your build.
See Figure 37.
__ Step 3. Use a flat blade screwdriver to install all of the caged nuts, you will have to view three assembly pictures. Use a flat blade screw driver to press the capture edge of the nut into the EIA strip.

__ Step 4. Read the following before doing steps 5a, 5b , 5c, and 5d. These caged nuts must be pressed into the square hole [using a flat blade screw driver]. Once they are seated, they will maintain their position.
Next, using the Allen wrench«11¬supplied, insert the socket button head screws«6¬through the EIA strip and into the caged nuts«8¬.
Leave the screws loose enough to insert the slide mounting brackets
«32¬between the screw head and the EIA strip«31¬. See Figure 36 on page 81 for referencing captured nut installations.
__ Step 5.
__ Step a. See Figure 37 on page 82 to install four M6 caged nuts«8¬
for the left side slide. Insert and leave the corresponding screws«6¬ loose.
__ Step b. See Figure 38 on page 84 to install four M6 caged nuts«8¬
for the right side slide. Insert and leave the corresponding screws«6¬ loose.
__ Step c. See Figure 37 on page 82 and Figure 38 on page 84 to insert one each M4 caged nuts«7¬. These will be used to retain the 3570 from free sliding out of the rack.
__ Step d. See Figure 42 on page 88 to install two M6 caged nuts«8¬
for the articulated arm hinge. Viewed from the front of the rack, install the caged nuts on the right rear EIA strip.
Ensure there is one open hole above the top slide caged nut.
__ Step 6. It is suggested that you have another person assist you in steps 6 through 8. Reference Figure 37 on page 82 and take the left-hand slide assembly«33¬and, ensuring that the slide (the part without mounting brackets«32¬) extends toward the front of the rack, install the assembly.
It is necessary to lengthen the slide mounting brackets to correctly mount them to the outside of the rack EIA strip. To accomplish this, do not loosen the front mounting bracket screws. Adjustment must be made with therearmounting bracket screws.
Slide Bracket Adjustment Procedure:
a. You must adjust each slide to the Netfinity Rack.
b. Loosen the rear bracket screws. Capture the front slide bracket under the button head screws, adjust the rear slide bracket to fit under the rear button head screws, and snug the rear bracket screws.
c. Remove the left-hand slide assembly, tighten the rear bracket screws, and do not install the left-hand slide assembly yet.
d. Before permanently installing the left-hand slide assembly to the EIA strip, use it as a template (or gauge) to adjust and tighten the right-hand slide and tray assembly rear brackets.
__ Step 7. Once the right-hand slide is adjusted, you can proceed to install the left slide assembly onto the rack. Firmly tighten the front and rear screws
«6¬ into the EIA strips.
__ Step 8. See Figure 38 on page 84 to install the right-hand slide and tray assembly«35¬.

__ Step a. For good sense, this is a two person operation; one in the front and one in the rear of the rack. Ensure the four library mounting tabs«34¬are pointing in the up orientation.
Looking from the front, tilt the left side of the slide and tray assembly up and insert it into the rack area. (The square hole in the center of the tray can be used as a hand hold.) Insert the brackets«32¬on the outside of the EIA strips between the screw heads and the EIA strip. As you do this, lower the left side, thus forcing the whole assembly to the right-most position. This will ensure that the tray is at a level orientation. Do not tighten slide assembly screws«6¬
at this time.
__ Step 9. See Figure 39 on page 85 to attach the tray to the left-hand slide.
Figure 38. Attaching Right-Hand Slide, Bracket, and Tray Assembly
Tabs«34¬on tray«35¬are facing upward.
__ Step a. Now, look back to Figure 38 on page 84 and securely tighten the front and rear right slide assembly screws«6¬) onto the EIA strip.
__ Step b. See Figure 39, slide the tray out to its fully extended locking position.
1) Get the three Phillips-head or pan-head screws (items
«4¬or«5¬ are referenced as items«37¬,«38¬, and
2) To install the front screw«37¬, slightly raise the tray and align the slide clearance hole to the threaded hole in the tray.
3) Install the rear screw«38¬.
4) Next, unlock and move the slide tray inward to align the center screw hole«39¬, and insert the screw.
__ Step c. Tighten all screws«37¬,«38¬, and«39¬. Thread the three nuts«9¬ onto the three screws you have just installed and tighten the nuts.
