Direct (1:1) Connections

This section describes direct (1:1) connections (definition below) and shows you connection examples. Definition of a Direct (1:1) connection:

a single length of cable joins the Black Box device and your equipment; there is no structured cabling system or any other connectionin-between.

Notes:

1.Some user equipment need additional signals on the connector. These may not be supported by the Black Box device or your cable. The normal way to overcome this is to loopback - on your equipment - one of the output lines to the required input. Refer to the documentation supplied with your equipment, or the supplier of the equipment, for information on which loop-backs,if any, are required.

2.Other than a specific requirement at your equipment (as in note 1), do not connect unused pins on either connector.

3.Protective Ground (P/GND) terminates on the connector and so does not have a pin number.

Example direct connections

In this section we show example connections between Black Box ports and the following devices:

Sun Microsystem servers on page 132
