Attaching the shelf brackets
Complete the following steps to install the shelf brackets to the cabinet rails:
1.
Find the left and right rack mount shelf brackets (
A
and
B
in Figure 4) in
the 14U rack mount kit. These brackets are adjustable to allow for different
cabinet depths.
2. Loosen the adjusting screws on both brackets enough to allow the brackets to
slide easily to adjust the length.
3.
Position the shelf brackets (
A
and
B
) with the adjustable ends at the intake
aisle side of the cabinet (see Figure 4) and attach them to the cabinet rails.
v For rails with round holes: Use eight screws with lock washers (
E
) for each
bracket, four at each end. Tighten the screws to a torque of 92 cm-kg (80
in.-lb).
v
For rails with square holes: Use eight screws (
G
) eight alignment washers
(
H
) for each bracket, four at each end. Tighten the screws to a torque of 92
cm-kg (80 in.-lb).
Note: Standard EIA rails have holes in sets of three; spaces between the holes
are 1.58 cm, 1.58 cm, 1.27 cm (5/8 in., 5/8 in., and 1/2 in.). If cables are
to be routed down through the cable management comb, allow at least
1U space below the brackets for cable management.
