Physical Description

2.2.2.3

Fan Connector (J1)

The fan connector (J1) is intended to power the DECchip 21066 processor’s
specified heatsink fan, or an enclosure mounted fan, not to exceed
250 mA. J1 is a 3-position vertical male-keyed connector.

CAUTION: Exceeding 250 mA may damage the MLB.

Table 2–3 lists the pin numbers and functions for the fan connector.
