DANGER
v
Plug power cords from devices in the rack cabinet into electrical outlets that are located near the
rack cabinet and are easily accessible.
v
Each 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.
v
Install 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.
v
Connect 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.
v
Do not run cables in front of or behind other devices that will prevent service access to those devices.
v
Do not bend cables beyond the specified limits.
v
Label all cables so that they are clearly distinguishable from each other.
v
When you install devices that are mounted on slide rails, such as servers, observe the following
precautions:
– 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 you can fully extend the device without straining the cables.
– Secure the cables so that you can retract the device without pinching or cutting the cables.
v
When you install devices that are mounted on fixed rails, observe the following precautions:
– 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.
v
Make sure that the cables cannot be pinched or cut by the rack cabinet rear door or other devices.
v
Run internal cables that connect devices in adjoining racks through the large openings in the rear of
the rack cabinet.
v
Run external cables through the bottom of the rack cabinet or through the cable-access opening in the
top of the rack.
Front-to-rear cable channels
You can route cables from the front to the rear of the rack cabinet by using the cable channels on the
sides of the rack. There are two cable channels on each side of the rack cabinet.
Before you use a cable channel, remove the cable channel cap. You can use a flat-blade screwdriver or a
similar tool to pry the cap off the end of the channel. If a cable channel is not being used, keep the cap in
place to prevent hot air recirculation from the rear of the rack to the front of the rack.
