(Optional) Installing the Cable Tray for a 4 U Disk Enclosure

Prerequisites

The following installation tools and materials have been prepared:

• M3 and M6 screws
• Phillips screwdriver (M3 to M6)
• Marker
• Protective gloves
• Cable trays and trays
• Square-hole positioning pins (for square-hole mounting bars)
• Round-hole positioning pins (for round-hole mounting bars)

Context

• If each controller is equipped with more than three interface modules, install a cable tray to facilitate maintenance and cabling of interface modules.
• You are advised to install a cable tray 1 U (1 U = 44.45 mm) under the controller enclosure.

Procedure

1. Determine the position for a cable tray. If the position is covered by a filler panel, mark the position.
2. Extend the adjustable guide rail of the cable tray until positioning pins are inserted into the rear column.
3. Use M6 screws to secure the adjustable guide rail, as shown in Figure 4-73.

4. Use a Phillips screwdriver to fasten the M3 screws to secure the tray in place, as shown in Figure 4-74.

   If the tray is too close to the controller enclosure, perform Step 5 and Step 6 to adjust the length of the cable tray for convenient cable trimming.

5. (Optional) Loosen the M3 screws on the cable tray and adjust the position of the guide rail for convenient cable trimming, as shown in Figure 4-75.
