Installing the FR42612L Cabinet

Prerequisites

The following tools are ready:

• Multimeter
• Flat-head screwdriver, Phillips screwdriver, and adjustable wrench
• Measuring tape, marker, powder marker, level, right angle, protective gloves
• Ladder
• M6 screw
• Floating nut mounting bar

Meters and other dedicated tools have been checked and calibrated.

Procedure

1. Check the installation environment and materials. Verify that:
   • The device types and quantity are the same as those in the packing list.
   • The cabinet appearance is in good condition and free of collision and scratch.
   • The area, height, and ground bearing capacity of the installation position meet the requirements.

2. Determine and outline the installation position.
   1. Check the engineering drawings to determine the position for installing the cabinet. Align the measuring tape with the upper edge of the installation position, and mark the upper edge by using a marker.
   2. Use the powder marker to outline the position for installing the cabinet.

      Figure 5-3 shows the outline for installing a single cabinet.

   Figure 5-3 Outline for installing a single cabinet
   

   Figure 5-4 shows the outline of the positions for installing combined cabinets.

   Figure 5-4 Outline for installing combined cabinets
   

3. Roll the cabinet on its castors to the installation position.
   1. Roll the cabinet to the outlined installation position.
   2. Align the cabinet edges with the outlined lines by using a right angle ruler, as shown in Figure 5-5.
   Figure 5-5 Placing a cabinet
   

   Ensure that the left or right edge of the cabinet and the outer edge of the rear door are aligned with the lines on the floor when positioning the cabinet.

4. Secure the cabinet on the floor using its leveling feet.
   1. Open the front and rear doors. See (1) in Figure 5-6.
   2. Rotate the four leveling feet clockwise by using a Phillips screwdriver to lower the leveling feet. See (2) in Figure 5-6.
   3. Rotate the M12 bolts at the bottom of the leveling feet clockwise by using an adjustable wrench to ensure that the leveling feet contact the floor and the castors hang in the air. See (3) in Figure 5-6.
      Figure 5-6 Securing a cabinet
      
      • Spin the castors by using a Phillips screwdriver. If the castors rotate freely, they are hanging in the air.
      • H indicates the height from the cabinet top to the floor. The value of H ranges from 1995 mm to 2005 mm. The height of the support feet is adjustable.
   4. Make sure that the heights measured from the front, rear, right, and left of the cabinet are the same.

5. Adjust the levelness and verticality of a cabinet by raising or lowering its leveling feet.
   1. Use a level and plumb line to check the levelness and verticality respectively.
   2. If the cabinet is not level, use an adjustable wrench to raise or lower the leveling feet.
   Figure 5-7 Leveling a cabinet
   
   • Check the levelness in the front and at the rear of the cabinet.
   • To check levelness, lay a level. If the bubble is in the middle of the level when it is static, the cabinet is level.
   • The height of a leveling foot is adjustable from 0 to 10 mm.

6. (Optional) After securing and leveling two or more adjacent cabinets, combine the cabinets.
   1. Remove the screws from the connection plates on the front and rear doors using a Phillips screwdriver. See (1) in Figure 5-8.
      • The cabinet in the middle provides four connection points on the front and rear doors respectively.
      • The cabinet on the leftmost or rightmost side provides two connection points on the front and rear doors respectively.
      • Ensure that the vertical deviation and the distance between cabinets are not greater than 3 mm after the cabinets are combined.
   2. Pass the connection plate through the gap on the cabinet door and secure it using the removed screws. See (2) in Figure 5-8.
      Figure 5-8 Combining adjacent cabinets
      

   3. Check that the cabinets are properly combined. See (3) in Figure 5-8.

7. Install PDUs.

   Power distribution units (PDUs) provide power for components in a cabinet. Install the PDUs vertically on the PDU installation plates on both sides at the back of the cabinet.

   1. Fit the upper and lower round tabs on the PDU rear panel into pear-shaped holes on the PDU installation plate and push them downwards to lock the PDU.
      Figure 5-9 Installing a PDU
      

      It is recommended that two persons collaborate to install the PDU so that PDU tabs can be easily oriented to the installation holes.

   2. Use the Phillips screwdriver and M6 screws to fix the PDU.
   3. Repeat 7.a and 7.b to install a PDU on the other side of the cabinet.

8. Install PGND cables and power cables for the cabinet.

   For details on how to install the PGND cables and power cables for the FR42612L cabinet, see Installing PGND Cables and Power Cables.

9. (Optional) Remove filler panels.

   If the cabinet has filler panels, remove them before installing devices. If the cabinet does not have filler panels, skip this step.

   1. Use a M6 Phillips screwdriver to remove M6 screws from the filler panel.
   2. Remove the filler panel from the cabinet.
   3. Use a floating nut mounting bar to remove floating nuts.

      If no floating nut mounting bar is available, a flat-head screwdriver can be used instead. When using a flat-head screwdriver to remove floating nuts, do not exert excessive force to prevent personal injury or damage to storage devices.

      Use the floating nut mounting bar to pull one foot of the floating nut downward, and then take the floating nut out. Repeat this step to remove all floating nuts.
