Rack-Mounting the Chassis

 Caution

Before you proceed, ensure that you are familiar with the safety information described in the BTI7800 Series Hardware Overview and Installation Guide.

Note

Be familiar with the electrical and occupational safety guidelines for your country, for example:

  • In the United States, refer to the latest edition of The National Electrical Code (NEC), and the latest guidelines of the U.S. Department of Labor, Occupational Safety & Health Administration (OSHA).

  • In Canada, refer to the latest edition of The Canadian Electrical Code (CEC), and the latest guidelines of the Canadian Centre for Occupational Health and Safety (CCOHS).

Rack-Mounting the BTI7814 Chassis

Use this procedure to mount the BTI7814 onto a rack.

Rack size

ANSI 19 in

ETSI 600 mm

ANSI 23 in

Cabinet size

ETSI 600 mm x 600 mm - for DC chassis kits only

NEBS 24 in (depth) - for DC chassis kits only

Note: For the BTI7814 with the AC chassis kit, ensure the selected cabinet has sufficient depth.

Chassis placement in rack

For rack stabilization, load the rack from the bottom up with the heaviest chassis at the bottom.

Number of chassis in a rack

Up to three chassis can be installed in a rack. There are no spacing requirements for the amount of space between chassis.

Installation Tools and Kits

  • Number 1 and Number 2 Phillips screwdrivers

  • 10 mm socket wrench

  • T15 Torx® screwdriver (for fastening mounting brackets onto the chassis)

  • Chassis Installation Kit (BT8A7865)

  • 14-Slot Chassis Shelf Installation Support Bracket Kit (BT8A78SSB1) - optional

If you are using the optional 14-Slot Chassis Shelf Installation Support Bracket Kit (BT8A78SSB1), see also Lifting and Moving the BTI7814 Chassis.

  1. Install the correct mounting brackets for the desired rack width.

    Mounting brackets for 19-inch, 600-mm, and 23-inch racks are supplied.

  2. Get into chassis lifting position.
    • If using a mechanical lift aid, at least two people are required. The chassis should be center balanced.

    • Three people: Two in the front, and one positioned center chassis back.

    • Four people: Two in the front and two in the back, each positioned at a corner of the chassis.

  3. With the chassis front facing, grasp the chassis from the bottom, with all personnel positioning their hands on the chassis in the positions stated in Step 1, to ensure proper chassis balance.
  4. At the same time, each person slowly lift the chassis and slide it onto the rack until the chassis mounting brackets meet the rack posts.
  5. Align the chassis mounting bracket holes with the rack post holes.
  6. Insert each screw, loosely, through the lock washer then the flat washer, through the bracket, and finally into the rack post holeone screw in the top bracket hole on each side, and one screw in the bottom bracket hole on each side. When all the screws are in place, tighten the screws into the rack post.
  7. Verify that the chassis is properly placed in the rack, and check each screw to ensure it is securely tightened.

Chassis placement in rack

For rack stabilization, load the rack from the bottom up with the heaviest chassis at the bottom.

Number of chassis in a rack

Up to 14 BTI7802 chassis can be installed in a standard 42U server rack. There are no spacing requirements for the amount of space between chassis.

Installation Tools and Kits

  • Number 1 and Number 2 Phillips screwdrivers

  • Chassis Installation Kit (BT8A7865)

Note

23-inch and 19-inch mounting brackets are assembled on every shipped BTI7802 chassis. 21-inch mounting brackets are packaged as a separate item and are shipped with the chassis. Before you begin this procedure you should remove unnecessary mounting brackets by unfastening and removing the screws that attach the brackets to the chassis. Re-use previously mounted bracket screws should you require to attach the 21 inch mounting brackets.

  1. Place the BTI7802 on a flat surface with the front facing you.

    Verify if you need to remove or install the mounting brackets.

  2. If you are mounting the chassis in a 23-inch rack or frame, verify if you need to install the BTI7802 Chassis Rear Exhaust Adapter.

    See Installing the BTI7802 Chassis Rear Exhaust Adapter.

  3. Get into rack-mounting position. Choose one of the following options:
    • One person is needed if the chassis is being seated on a rack shelf.

    • For balance, two people are needed if the chassis is not being seated on a rack shelf. One person should be positioned at the center front of the chassis and the other at the center back.

  4. Align the chassis mounting bracket holes with the rack post holes.
  5. Insert each screw, loosely, through the lock washer then the flat washer, through the bracket, and finally into the rack post holeone screw in the top bracket hole on each side, and one screw in the bottom bracket hole on each side. When all the screws are in place, tighten the screws into the rack post.
  6. Verify that the chassis is properly placed in the rack, and check each screw to ensure it is securely tightened.

Chassis placement in rack

For rack stabilization, load the rack from the bottom up with the heaviest chassis at the bottom.

Number of chassis in a rack

Up to 42 BTI7801 chassis can be installed in a standard 42U server rack. There are no vertical spacing requirements for the amount of space between chassis.

Installation Tools and Kits

  • Number 2 Phillips screwdriver

  • 10-mm socket wrench

  • Chassis Installation Kit (BT8A7865)

  • BTI7801 Chassis Support Bracket Kit (BT8A78SSB3) - for use in 4-post 19-inch and ETSI 600-mm cabinets

  1. Place the BTI7801 on a flat surface with the front facing you.
  2. Install the correct mounting brackets for the desired rack width.

    Mounting brackets for 19-inch, 600-mm, and 23-inch racks are supplied.

  3. Get into rack-mounting position. Choose one of the following options:
    • One person is needed if the chassis is being seated on a rack shelf.

    • For balance, two people are needed if the chassis is not being seated on a rack shelf. One person should be positioned at the center front of the chassis and the other at the center back.

  4. Align the chassis mounting bracket holes with the rack post holes.
  5. Insert each screw, loosely, through the lock washer then the flat washer, through the bracket, and finally into the rack post holeone screw in the top bracket hole on each side, and one screw in the bottom bracket hole on each side. When all the screws are in place, tighten the screws into the rack post.
  6. If you are mounting the BTI7801 into a 4-post 19-inch or ETSI 600-mm cabinet, and if there is no other equipment immediately below the BTI7801 to provide support, attach the BTI7801 Chassis Support Bracket (BT8A78SSB3) onto the rear posts to support the rear of the chassis.

    Working from the rear of the rack, insert each screw, loosely, through the lock washer then the flat washer, through the bracket, and finally into the rack post hole. The support bracket requires four sets of screws, two for each rear post. All screws and washers are included in the BT8A78SSB3 kit. When all the screws are in place, tighten the screws into the rack post.

    If you are mounting multiple BTI7801 chassis, one on top of the other, only the bottom BTI7801 chassis requires the support bracket. The support bracket should not be used if you are mounting the BTI7801 directly on top of other equipment.

  7. Verify that the chassis is properly placed in the rack, and check each screw to ensure it is securely tightened.
