Multiple cabinet configurations require the cabinets to be connected to each other side by side (ganged). Hex spacers, located between the cabinets, front and rear, are used to gang the cabinets.
Teradata recommends that a minimum of all four corners of ganged cabinets be secured with hex spacers. The cabinets need to be secure at the top and bottom of both the front and rear.

Actual cabinet width is 61 cm (24 in.) without side panels. To ensure exact alignment for ganged cabinets, use the exact width when drawing up floor plans and cutting floor tiles.

Cabinets must be ganged together before the customer installs seismic bracing.

Ganging to legacy cabinets is not supported. Teradata recommends that ganged legacy cabinets be spaced one floor tile (24 in.) from current system.
  1. If a cabinet has side panels attached, remove one or both, depending on which side or sides will mate. Set aside the panels for reattaching at the ends of the row.
  2. Remove the doors. See Installing Cabinet Side Panels and Doors.
  3. Locate the cutouts in the outer edge of the rack frame.
  4. Align the cutouts of one cabinet with the cutouts on the adjacent cabinet. You will be installing a minimum of four hex spacers, one at each corner of the rack.
  5. Remove the six hex spacers, twelve screws, and twelve flat washers from their bag.
  6. Insert the hex spacer between the cabinets in the cutout provided in one of the corners of the rack. You may need a pair of small pliers or a wrench to hold the spacer in place.
  7. Using your hand, or a Phillips screwdriver, insert one screw and washer through the rack and into the open end of the hex spacer.

  9. Hold the hex spacer with a wrench or pliers, and tighten the screws until the cabinet frames come together.

  10. Repeat steps 6 through 9 for the remaining frame corners (three).
