procedures while the system is extended fromthe rack and still attached to the rack
rails. If qualified service providers want to removethe system from the rack for any
other reason, they should follow the instructions in this section.

tip legs and adjust their stabilizing feet to the floor.Level and secure the cabinet to
provide a safe working environment.
Caution – The chassis is heavy.Two persons are required to remove the system
from the rack enclosure in the following steps.
Before You Begin

■Identify a helper to assist you in removing the system.
■Discuss each task step and verify that your helper can safely lift and carry 34 lb
(17 kg), which is approximately half the weight of a fully-equipped system.
■Review the steps in the procedure with your helper beforehand and discuss how
to coordinate your efforts to ensure your mutual safety.
Caution – When completing a two-person procedure, always communicate your
intentions clearly before, during, and after each step to minimize confusion.
