Removing the Chassis from a Rack
To remove the chassis from a 2-post or 4-post equipment rack, follow the instructions in this section.
WARNING: Due to the weight of a fully populated C9010 chassis, never pull a full chassis out of a rack with ReadyRails. Remove
each component before you remove the chassis.
CAUTION: Always wear an ESD-preventive wrist or heel ground strap when handling the switch and its components. Ground
yourself by using an antistatic wrist strap or other device and connect it to the ESD grounding jack on the chassis. As with all
electrical devices of this type, take all necessary safety precautions to prevent injury when installing this system.
CAUTION: Use an equipment lift or pallet or jack or have two people available to lift the chassis when you remove it from a rack.
Lifting the system by its shelves will cause damage to the chassis.
1 Power o the switch before removing it from the rack.
2 If you removed the rack bar after installing the chassis in the rack, re-install the rack bar to support the weight of the chassis when
you remove it.
3 Remove all eld-replaceable components (fans, power supplies, line cards, RPMs) from chassis and unplug all cabling before removing
it from the rack.
4 Position an equipment lift or pallet jack under the chassis or have two people in front of chassis ready to lift it. Loosen the
thumbscrews and rack screws that hold the chassis in the rack. The chassis should fall slightly onto the equipment lift if it is supported
only by a rack bar. If a rack mount tray or ReadyRails are used, the chassis sits on them.
5 In a 2-post threaded-hole rack, remove the rack screws that hold the chassis in the rack; in a 4-post non-threaded-hole rack, remove
the thumbscrews.
• If only a rack bar is used, allow the weight of the chassis to be supported by the equipment lift or by two people.
• If a rack mount tray or ReadyRails are used, the weight of the chassis is supported.
6 Carefully remove the chassis from the rack by backing up the equipment lift or pulling the chassis out of the rack. If ReadyRails are
used, a person on each side of the chassis must press down the blue safety tab on the right and left rack rail to allow the chassis to be
pulled forward. Then pull the chassis out of the rails.
