Chapter 4. Managing cables
Always read the instructions that come with your server or optional device for detailed cable-management
information. Use the following general guidelines when cabling servers or optional devices that you install
in a rack.
Statement 8:
DANGER
•
Plug power cords from devices in the rack cabinet into electrical outlets that are located
near the rack cabinet and are easily accessible.
•
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.
•
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.
•
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.
•
Do not run cables in front of or behind other devices that will prevent service access to those devices.
•
Do not bend fiber-optic cable beyond its specified limits.
•
Label all cables so that they are clearly distinguishable from each other.
•
When installing devices 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 the device can fully extend without straining the cables.
-
Secure the cables so that the device can retract without pinching or cutting the cables.
•
When installing devices mounted on fixed rails, observe the following precautions:
-
Run the cables neatly along the posts or side rails in the rack out of the way of other installed
devices.
-
Secure the cables with the provided cable straps.
•
Make sure that the cables cannot be pinched or cut by the rack rear door or other devices.
•
Run internal cables that connect devices in adjoining racks through the large openings in the rear of the
rack.
•
Run external cables through the bottom of the rack or through the cable-access opening in the top of the
rack.
Cable-routing brackets
To route cables neatly in the rear of the racks, use the cable-routing brackets that come in the hardware
kit. The rack comes with eight cable-routing brackets. Use a screwdriver to install or remove a bracket on
the rack-mounting flange in the rear of the rack.
