Figure 1-3 Front Connector Pin Assignment and Labeling on the CP 343-2

The CP 343-2 has internal contacts for two AS-i cables that are jumpered internally

on the CP. This allows the CP 343-2 to be “looped” into the AS-i cable.

Notice

The load capacity of the contacts is a maximum of 4 A. If this value is exceeded

on the AS-i cable, the CP 343-2 must not be “looped into” the AS-i cable but must

be connected by a separate cable (only one pair of contacts used on the

CP 343-2).

For further information on connecting the AS-i cable, refer to Section 2.2.
