vConnect all power cords to a properly wired and grounded electrical
outlet. Ensure that the outlet supplies proper voltage and phase rotation
according to the system rating plate.
vConnect any equipment that will be attached to this product to properly
wired outlets.
vWhen possible, use one hand only to connect or disconnect signal
cables.
vNever turn on any equipment when there is evidence of fire, water, or
structural damage.
vDisconnect the attached power cords, telecommunications systems,
networks, and modems before you open the device covers, unless
instructed otherwise in the installation and configuration procedures.
vConnect and disconnect cables as described in the following procedures
when installing, moving, or opening covers on this product or attached
devices.
To disconnect:
1. Turn off everything (unless instructed otherwise).
2. Remove the power cords from the outlets.
3. Remove the signal cables from the connectors.

Safety ix

DANGER
Observe the following precautions when working on or around your IT rack
system:
vHeavy equipment—personal injury or equipment damage might result if
mishandled.
vAlways lower the leveling pads on the rack cabinet.
vAlways install stabilizer brackets on the rack cabinet.
vTo avoid hazardous conditions due to uneven mechanical loading,
always install the heaviest devices in the bottom of the rack cabinet.
Always install servers and optional devices starting from the bottom of
the rack cabinet.
vRack-mounted devices are not to be used as shelves or work spaces. Do
not place objects on top of rack-mounted devices.
vEach rack cabinet might have more than one power cord. Be sure to
disconnect all power cords in the rack cabinet when directed to
disconnect power during servicing.
vConnect all devices installed in a rack cabinet to power devices installed
in the same rack cabinet. Do not plug a power cord from a device
installed in one rack cabinet into a power device installed in a different
rack cabinet.
vAn 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.

xIBM System Networking RackSwitch G8124 and G8124-E: Installation Guide

CAUTION:
vDo not install a unit in a rack where the internal rack ambient temperatures
will exceed the manufacturer’s recommended ambient temperature for all
your rack-mounted devices.
vDo 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
used for air flow through the unit.
vConsideration should 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 located 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 completely out of the rack might cause the rack to
become unstable or cause the drawer to fall out of the rack.
