DANGER
vPlug power cords from devices in the rack cabinet into electrical outlets
that are located near the rack cabinet and are easily accessible.
vEach rack cabinet might have more than one power cord. Be sure to
disconnect all power cords in the rack cabinet before servicing any
device in the rack cabinet.
vInstall an emergency-power-off switch if more than one power device
(power distribution unit or uninterruptible power supply) is installed in
the same rack cabinet.
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.
vDo not run cables in front of or behind other devices that will prevent service
access to those devices.
vDo not bend fiber-optic cable beyond its limited specifications.
vLabel all cables so that they are clearly distinguishable from each other.
vWhen installing devices mounted on slide rails, such as servers:
– Run the cables neatly along equipment cable-management arms and secure
the cables to the arms using provided cable straps.
– Leave enough extra cable so that the device can fully extend without straining
the cables.
– Secure the cables so that the device can retract without pinching or cutting
the cables.
vWhen installing devices mounted on fixed rails:
– Run the cables neatly along the posts or side rails in the rack cabinet out of
the way of other installed devices.
– Secure the cables with the provided cable straps.
vEnsure that the cables cannot be pinched or cut by the rack cabinet rear door or
other devices.
vRun internal cables that connect devices in adjoining rack cabinets through the
large openings provided in the rear of the rack cabinet.
vRun external cables through the bottom of the rack cabinet or through the
removable section in the top of the rack cabinet.
Cable-management brackets
If your rack cabinet comes with cable-management brackets, you must remove the
indicated screw before you can remove a filler panel from the rack cabinet. Youcan
install the bracket FRU on either type of rack cabinet. If you install these brackets
on a rack cabinet that did not originally come with them, you cannot use a screw to
secure the filler panels unless you also install the new filler panels.
