v An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the
system or the devices that attach to the system. It is the responsibility of the customer to ensure that
the outlet is correctly wired and grounded to prevent an electrical shock. (R001 part 1 of 2)
Caution
v Do not install a unit in a rack where the internal rack ambient temperatures might exceed the
manufacturer's recommended ambient temperature for all your rack-mounted devices.
v Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not blocked
or reduced on any side, front, or back of a unit that is used for air flow through the unit.
v Consideration must be given to the connection of the equipment to the supply circuit so that
overloading of the circuits does not compromise the supply wiring or overcurrent protection. To
provide the correct power connection to a rack, refer to the rating labels on the equipment in the rack
to determine the total power requirement of the supply circuit.
v (For sliding drawers) Do not pull out or install any drawer or feature if the rack stabilizer brackets are
not attached to the rack. Do not pull out more than one drawer at a time. The rack might become
unstable if you pull out more than one drawer at a time.
v (For fixed drawers) This drawer is a fixed drawer and must not be moved for servicing unless
specified by the manufacturer. Attempting to move the drawer partially or out of the rack might cause
the rack to become unstable or cause the drawer to fall out of the rack. (R001 part 2 of 2)
Caution
Removing components from the upper positions in the rack cabinet improves rack stability during
relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room
or building:
v Reduce the weight of the rack cabinet by removing equipment, starting at the top of the rack cabinet.
When possible, restore the rack cabinet to the configuration of the rack cabinet as you received it. If
this configuration is not known, you must do the following:
– Remove all devices in the 32U position (compliance ID RACK-001) or 22U (compliance ID RR001)
and above.
– Ensure that the heaviest devices are installed in the bottom of the rack cabinet.
