When connecting or disconnecting power to hot-pluggable power supplies, if
offered with your Dell product, observe the following guidelines:
— Install the power supply before connecting the power cable to the power
supply.
— Unplug the power cable before removing the power supply.
— If the system has multiple sources of power, disconnect power from the sys-
tem by unplugging all power cables from the power supplies.
Move products with care; ensure that all casters and/or stabilizers are firmly con-
nected to the computer or storage system. Avoid sudden stops and uneven
surfaces.
Observe the following precautions for rack stability and safety. Also refer to the rack
installation documentation accompanying the system and the rack for specific warn-
ing and/or caution statements and procedures.
Server and storage systems are considered to be components in a rack. Thus, “com-
ponent” refers to any server or storage system, as well as to various peripherals or
supporting hardware.

NOTE: Dell’s server and storage systems are certified as components for use in Dell’s
rack cabinet using the Dell customer rack kit. The final installation of Dell systems and
rack kits in any other brand of rack cabinet has not been approved by any safety agen-
cies. It is the customer’s responsibility to have the final combination of Dell systems
and rack kits for use in other brands of rack cabinets evaluated for suitability by a certi-
fied safety agency.
System rack kits are intended to be installed in a Dell rack by trained service tech-
nicians. If you install the kit in any other rack, be sure that the rack meets the
specifications of a Dell rack.
Do not move large racks by yourself. Due to the height and weight of the rack,
Dell recommends a minimum of two people to accomplish this task.
Before working on the rack, make sure that the stabilizers are secure to the rack,
extend to the floor, and that the full weight of the rack rests on the floor. Install
front and side stabilizers on a single rack or front stabilizers for joined multiple
racks before working on the rack.
