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.
4. Tighten the adjusting screws on the shelf brackets to a torque of 37 cm-kg (32
in.-lb).
5. Attach the clip nuts
D
(for rails with round holes) or retainer nuts
F
(for
rails with square holes) to the vertical rails on the exhaust aisle side of the
cabinet (see Figure 5 on page 21). These nuts are used for securing the port side
of the chassis to the rack rails using 10-32 x 5/8-inch screws. Use three nuts on
each rail. Place the nuts in optimum locations for securing the chassis to the
rails. See Figure 7 on page 23 for approximate positions.
Note: Do not align the clip or retainer nuts with the top or bottom holes of the
SAN768B-2 mounting brackets because the door will interfere with the screw
