30 Installation
4. Tighten the adjusting screws on the rack mount shelf brackets to a torque of 32 in.-lbs (37 cm-kgs).
5. Attach the clip or retainer nuts to the vertical rails on the exhaust aisle side of the cabinet ( Figure 5 ).
These clip 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 clips on each rail. Place the clips in optimum locations for securing the chassis to the
rails.
NOTE: Do not align the clip or retainer nuts with the top or bottom holes of the Brocade DCX mounting
bracket because the door will interfere with the screw heads.
• For rails with round holes:
Attach clip nuts (Item D) to each of the front rails.
• For rails with square holes:
Attach retainer nuts (Item F) to each of the front rails.
CAUTION: Use the screws specified in the procedure. Using longer screws can damage the chassis.
Removing the chassis door
See ” Removing the chassis door ” on page 30 to uninstall the chassis door.
Installing the chassis in the cabinet
To install the DC Director in the cabinet:
CAUTION: A fully populated DC Director (eight FC8-48 port cards, 384 ports) weighs approximately
104 kg (228 lbs) and requires a hydraulic or assisted lift to install it.
1. Use a lift to raise the chassis to the correct level.
2. Move the lift as close as possible to the rack, with the air-intake side of the chassis facing the front of the
rack (see Figure 6 ).
3. If applicable, lock the wheels of the lift.
4. Gently slide the chassis onto the shelf brackets, ensuring that it remains supported during the transfer.
5. Fasten the port side of the chassis to the cabinet rails. Use three 10-32 x 5/8 inch (1.58 cm) screws
(Item C) per rail. Tighten the screws to a torque of 32 in.-lbs (37 cm-kgs).
NOTE: Do not use the top or bottom holes of the DC Director mounting bracket because the door will
interfere with the screw heads.
