2-6 Setting Up the System
2. Remove the center slide bar from each rack mounting bracket assem bly as
follows:
! Position the rack mounting bracket assembly on a flat surface with the
center slide bar facing up.
! Fully extend the three telescoping slide bars until they lock in place
(see Figure 2-1).
! While pressing up on the center slide bar safety latch (see Figure 2-1),
slide the center slide bar out of the assembly and set aside for
installation on the BSU.
! Ensure that the safety latch on the extension rail assembly (see Figure
2-1) is centered and then collapse the center slide rail into the outer
bracket rail.
3. With each rack mounting bracket assembly on a flat surface remove the six
screws that attach their outer and inner brackets together and separate them
(see Figure 2-1).
4. Locate the fifth and sixth screw holes on the outer rack mounting bracket
(counting from the front of the bracket that has no front flange) and align its
inner bracket rear set of oblong holes over the fifth and sixth holes (see
Figure 2-2).
Note: This procedure is for mounting a BSU in a
1000 mm rack cabinet. For mounting in other types of rack
cabinets adjust the mounting bracket alignment procedures
accordingly.
5. Secure the two brackets together by inserting two screws in each of the
second, fifth, and sixth set of screw holes (see Figure 2-2). Snug up screws
but do not tighten.
6. Set the rack mounting bracket assemblies aside for rack installation.
A – Inner bracket
B – Second set of screw holes
C – Fifth set of screw holes
D – Sixth set of screw holes
E – Outer bracket
