Mounting the Wide Bank 28 DS3
4-4 July 2004 Wide Bank 28 DS3 - Release 2.4
Attaching Mounting Brackets to the Units
The included Universal Heavy-Duty Brackets (Carrier Access part number 710-0153) can be used
to mount the Wide Bank in either 19-inch or 23-inch racks, with either 1 3/4-inch or 2-inch vertical
hole spacing. These brackets are made up of four individual pieces. The following procedures show
how to assemble the brackets and attach them to a Wide Bank.
1. There are two bracket parts with right-angle bends (see Figure 4-1). Mount one of these on each
side of the Wide Bank to obtain the desired offset, as shown in Figure 4-2, using the #6 x 3/8-
inch mounting screws provided. Use the Wide Bank mounting holes nearest the front of the unit
to produce a typical flush mounting. Use the Wide Bank mounting holes nearest the rear of the
unit for a 5-inch or center offset to the front.
2. If you are mounting the Wide Bank in a 23-inch rack, fasten the other two bracket pieces to the
previously-mounted brackets, as shown in Figure 4-1, using the four 10-32 x 3/4" machine
screws provided.
3. Mount the chassis and bracket assembly on the rack, using 10-32 x 3/4" rack-mounting screws
in a manner appropriate for the selected mounting arrangement. See Rack Mounting - Non-FFO
Equipped Units on page 4-6 or Rack Mounting - FFO-Equipped Units on page 4-9, as required.
