Install additional mounting rails

If you are installing controller-drive trays, or drive trays that were shipped separately (not already installed in the cabinet), you might need to install additional mounting rails in the cabinet.

Steps

  1. Determine the location for the mounting rails.
    • Above an existing tray – Position the mounting rails immediately above the top tray in the cabinet.
    • Beneath an existing tray – Position the mounting rails with enough clearance to hold the tray being installed:
      • 8.9 cm (3.5 in.) for 2U controller-drive trays or drive trays
      • 17.8 cm (7 in.) for 4U controller-drive trays or drive trays
  2. Use the measurement markers on the right-front and left-front vertical supports to attach the mounting rails to the same position on each side of the cabinet.



    1. Front adjustable rail
    2. Rear adjustable rail
    3. Adjustment plate and screws
    4. Rail mounting M5×10mm screws
    5. Clip nuts
    6. Rear hold down bracket
    7. Vertical support
    Note: The clip nuts and the rear hold down bracket are not used when the rails are installed in a 3040 cabinet.
  3. Place the rear adjustable rail on the vertical support.
  4. On the rear adjustable rail, align the adjustable rail holes in front of the holes in the vertical support.
  5. Attach two M5×10mm screws.
    1. Attach the screws through the vertical support rail and the rear adjustable rail.
    2. Tighten the screws.
  6. Place the front adjustable rail on the vertical support.
  7. On the front adjustable rail, align the adjustable rail holes in front of the holes in the vertical support.
  8. Attach two M5×10mm screws.
    1. Attach one screw through the vertical support rail and the bottom hole of the front adjustable rail.
    2. Attach one screw through the vertical support rail and the middle of the top three holes in the front adjustable rail.
    3. Tighten the screws.
    Note: The remaining two screw holes are used to mount the tray.
  9. Repeat step 3 through step 8 to attach the second rail on the other side of the cabinet.
  10. Install each tray using the applicable tray installation instructions.
  11. Choose one of the following options:
    • If all positions for trays are full, power-on the trays.
    • If not all positions for trays are full, use front panel kits to cover the empty spaces above or below the installed trays.
  12. Go to Connect the cabinet to power.
