Positioning the expansion racks

Procedure

Determine the position of each expansion rack to be installed to this Rack-1.
1. When viewed from the front of Rack-1, each expansion rack is installed to the right. See Figure 1.
2. Use each expansion rack number label to ensure that the expansion rack is for this Rack-1. The label is at the left side of the rack, behind the front door, below the upper door hinge. The expansion rack label must list the correct Rack-1 serial number.
  
  Attention: This storage facility installation will fail if an expansion rack is for a different Rack-1. If the Rack-1 serial numbers do not match, stop the installation and call the next level of support.

  Note: Rack-4 and Rack-5 not shown. Some models do not use a Rack-3.
Does the expansion rack you are installing have EMI seals on the left side?
- Yes, go to step 5.
- No, continue with the next step.
Remember: You checked for this in step 1 of Extending all racks to full height and installing expansion racks. For racks with EMI seals, there are no trim pieces to install.
Install side trim pieces with gaskets on right side of Rack-1 at top, bottom, front, and rear. See Figure 2. The screws that are used to secure the trim pieces to the racks are described in Table 3.

Note: Each trim piece can come in one or two parts. Refer to Table 3.
1. Install front and rear trim pieces with gaskets and secure with screws. Each screw location has two holes. Insert the screw into the smaller hole. See Figure 3.
2. For models with extension panels, install trim pieces with gaskets on the right front and right rear extension panels.
3. Install the top and bottom trim pieces and secure with screws. Top piece gasket 1 goes up, bottom piece gasket 2 goes down. See Figure 3.

Install side trim pieces (without gaskets) on left side of Rack-2 at front and rear. See Figure 4.
Notes:
- Left side trim pieces (without gaskets) are front and rear only, there are no top or bottom pieces.
- Each trim piece can come in one or two parts. Refer to Table 3.
1. Install front and rear trim pieces and secure with screws. Each screw location has two holes. Insert the screw into the smaller hole.
2. For models with extension panels, install trim pieces (without gaskets) on the left front and left rear extension panels.

Note: Extension panels not shown.
Remove wheel chocks (if inserted) or raise the stabilizer feet of the expansion rack (if lowered).
Roll the expansion rack being installed into position.
1. Move the rack outriggers to stowed (operating) position for final positioning of each rack.
2. To move each outrigger, pull down on the release handle 2 located under the outrigger, and push the outrigger in. See Figure 5.

Position Rack-2 against Rack-1.
1. Position the rear of Rack-2 against the rear of Rack-1.
2. Pivot the front of Rack-2 against the front of Rack-1.
  
  Note: The rear rack wheels do not swivel. Position the rear of Rack-2 as close as possible to Rack-1 before pivoting the front of Rack-2.
Fasten Rack-2 to Rack-1. The screws and washers that are used to fasten the racks together are described in Table 3 and Table 4.
1. Basic racks are fastened by using five screws with washers in the front and five screws with washers in the rear. See Figure 6 and Figure 7.
2. Extension panels (if present) are fastened by using one additional screw with washer in the front and one additional screw with washer in the rear.
  
  Note: Suggested method is to install screws working top to bottom at rear, then top to bottom at front. You must partially lower the left front stabilization foot of Rack-2 to insert the bottom screw.

  Note: Front fastener positions are similar
