Chapter 2 Installing the Server Into a 19-Inch Cabinet 31
Managing Cables
You will need to develop a cable management scheme that is customized for your
installation. The Sun Fire V890 server rackmounting kit provides several tools that
may aid you in managing the server power cords and cables:
■ Server cable management bracket (with integrated releasable tie wraps) that
attaches to the rear of the server. See “Attach the Cable Management Bracket to
the Server” on page 16.
■ Cabinet cable management bracket (with separate releasable tie wraps) that
attaches to the rear of the cabinet. See “Attach the Cable Management Bracket to
the Cabinet” on page 32.
■ Three universal power jumper cords that enable you to provide additional slack
in the server power cords. See the following general guidelines for more
information.
In addition, some cabinets have cable management features or optional cable
management accessories.
The following general guidelines describe techniques for routing and managing the
server cables:
■ Allow enough slack in the server power cords and cables so that the tray
assembly can be fully extended from the front of the cabinet for service access. If
the server power cords are too short for your particular installation, three
universal jumper cords, provided with the rackmounting kit, allow you to gain
the additional slack needed. One end of a jumper cord plugs in to a Sun Fire V890
server power supply; the other end of the jumper cord plugs in to a Sun Fire V890
server power cord. The server power cord then plugs in to an AC power source.
■ To prevent bending or pinching of the cables when the tray assembly is fully
extended, be sure all cables are kept clear of the slides and other obstructions.
