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). 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 22 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 heads.
Removing the chassis door and cable management comb
The chassis door must be removed before the chassis can be installed into the
cabinet. The door is not hinged. It is held to the chassis by mounting hardware on
the door that snaps onto eight ball studs on the chassis. To remove the door, grip
both sides of the door, and gently pull the door straight out until it releases from
the ball studs on the chassis.
