Cable Labeling Reference Information
Use the information in this chapter to assist in cable planning and installation. Because several different
interfaces have cable connectors that are identical in appearance, labeling cables can help you keep track
of how each cable is being used and provide correct location data. This section provides examples of
cable labels that you can develop and use at your installation.
Identify the cables with information describing the type and location of the device it attaches. Use that
information to fill out the right hand side of the label.
Room The room number, or other information about the physical location of the
device.
Person The name of the person who uses the device.
Telephone # The nearest telephone number to the device.
Device Type This could be a printer, plotter, TTY, or similar device.
Device ID The device ID is determined at the time the software is configured on the
system.
Software Location Code The software location code is the link between the hardware and software.
This code appears in the software configuration menus and in the
hardware diagnostic menus.
Note: For specific location code information, refer to the Diagnostic
Information manual for your system.
Adapter Type The adapter type number is located on a label attached to the end of the
adapter. Refer to
Adapters, Devices, and Cable Information for Multiple
Bus Systems Systems , order number SA23-2778, or Adapters, Devices,
and Cable Information for Micro Channel Bus Systems , order number
SA23-2764, for a listing of adapter types.
Note: Some of the adapters in the multiple bus systems do not have an
adapter type.
Interface Name of the asynchronous adapters, and some network adapters,
generally includes the name of the interface.
EIA Used in a rack-type system unit to identify the physical location of the
drawer within the rack. The label along the right side of the rack (with rear
cover open) indicates numbers from 1, at the bottom, to 32, at the top of
the rack. The number at the bottom-right corner of the drawer is the EIA
location for this drawer.
Slot Physical position within the system unit or drawer where the adapter is
located. Each adapter slot is identified by a single digit number. Usually,
the number is embossed in the adapter mounting frame.
Connector Connector number on the adapter. Most adapters have only one
connector, so this number is 1.
Tailgate For rack-type system unit only. Record the number of the tailgate
connector to which this cable is attached.
System ID If an installation has more than one system unit, each one must be
identified to prevent connecting devices to the wrong system unit. The
customer determines the System ID.
