(Optional) Installing U-shaped Brackets and Adjustable Guide Rails

Prerequisites

• The installation positions of enclosures in the cabinet have been determined.
• The following installation tools and materials have been prepared:
  • Phillips screwdriver (M3 to M6)
  • Marker
  • M6 screws
  • Square-hole positioning pins (for square-hole mounting bars)
  • Round-hole positioning pins (for round-hole mounting bars)
  • U-shaped brackets

Precautions

• Storage devices must be installed on adjustable guide rails. Stacking devices may damage devices.
• The guide rails must be installed horizontally.

Before performing the installation, you are advised to count several U scales upward from the position of the first scale at the bottom of the mounting bar, and then mark the position. This can ensure that the front and rear heights of the adjustable guide rails are the same.

Context

• You are advised to install storage devices in a cabinet from the bottom up.
• A pair of adjustable guide rails is included with each storage device.
• The length of the adjustable guide rail ranges from 600 mm to 900 mm.
• The square-hole positioning pins come installed on the adjustable guide rails before delivery. If the installation holes of the screws are round, change the square-hole positioning pins to round-hole positioning pins before installing the adjustable guide rails.

You can find round-hole positioning pins in the accessory bag delivered with the devices.

The following is a recommended method for installing adjustable guide rails (using square-hole positioning pins as an example).

Procedure (Without U-shaped Brackets)

1. On the front of the cabinet, align the bottom margin of the adjustable guide rail with an integer U scale mark on the mounting bar, and fully insert the front positioning pin into the square hole.
2. Stretch the adjustable guide rail and thread the positioning pins through the rear square holes on the mounting bar.
3. Secure the adjustable guide rails with M6 screws.

   When securing an adjustable guide rail, attach M6 screws to the specified positions at the front side of the rail, as shown in Figure 4-61, Figure 4-62, and Figure 4-63. Using extra M6 screws or attaching the screw to other positions will cause collision with the device, resulting in device damage.

   • Secure the adjustable guide rails for a 4 U disk enclosure with M6 screws.

   • Secure the adjustable guide rails for a 4 U controller enclosure with M6 screws.

   • Secure the adjustable guide rails for a 2 U storage device with M6 screws.

Procedure (with U-shaped Brackets)

1. On the front of the cabinet, align the bottom margin of the adjustable guide rail with an integer U scale mark on the mounting bar, and fully insert the front positioning pin into the square hole.
2. Stretch the adjustable guide rail and thread the positioning pins through the rear square holes on the mounting bar.
3. Align the U-shaped brackets with the adjustable guide rails, and then use M6 screws to secure the U-shaped brackets and the adjustable guide rails, as shown in Figure 4-64.

4. (Optional) Install floating nuts on the U-shaped brackets.

   Floating nuts have been installed on U-shaped brackets before delivery. If no floating nuts have been installed, install a floating nut into the third hole on each U-shaped bracket.

   Insert and clamp one foot of the floating nut into the square hole. Pull the other foot of the floating nut by using the floating nut mounting bar to clamp it in the square hole.

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

Follow-up Procedure

• After the U-shaped brackets are fixed to the front mounting bar and the floating nuts are installed, install the storage device onto the U-shaped brackets, as shown in Figure 4-66 and Figure 4-67.

• U-shaped brackets can be stacked. When stacking the U-shaped brackets, comply with the following rules:
  • Stack two U-shaped brackets at most on each side.
  • Install the wide U-shaped bracket onto the adjustable guide rail and stack the other on it.
  • Install floating nuts in the first and fifth holes to connect two U-shaped brackets.
  Figure 4-68 shows how to stack two U-shaped brackets.
