7.Slide the bottom cover down to the bottom of the cabinet.

8.Align the five holes in the bottom cover with the five studs around the edge of the cabinet.

9.Install a flat washer and lock nut (removed in step 1 of Section 5.1) on each stud and tighten securely.

6.3Distribution Cable and Connector Panel Pigtail Splicing

The distribution cable must be spliced to the connector panel pigtails. Up to five 72-port connector panels may be mounted in the cabinet which requires a maximum of 360 distribution splices. Round splice trays are used for splicing and six splice tray mounting slots are provided per panel. This equates to a maximum of 30 spice trays when five connector panels are installed. Each splice tray can hold up to 12 splices. Use the following procedure to install the distribution cable fibers and the connector panel pigtails in the splice tray in preparation for splicing:

1.Locate splice tray #1 (on the left side) and remove that tray from the cabinet.

Note: The pigtails from each connector panel are grouped into six 12-fiber subunits. Each pigtail subunit is routed to a splice tray located on the left side of the cabinet. The splice trays are numbered consecutively 1 through 30 starting with at the top. The subunit, port, fiber, and splice tray designations for each connector panel are shown in Table 5.

2. Uncoil the connector panel pigtail subunit from the splice tray.

Note: Each connector panel pigtail subunit is temporarily coiled around a splice tray for storage.

3.Starting at the last column (left side) of tie points on the rear side of the connector panel, measure and mark the fiber cut lengths for the distribution cable fiber subunits and the connector panel fiber subunits as shown in Figure 25.

4.Cut both the distribution cable fiber subunit and the connector panel pigtail subunit at the cut length mark. Make sure that the distribution cable fiber subunit and the connector panel pigtail subunit are of equal length and the overall length is within the range specified.
