Power on the Expansion Bay Connector

Table 4-5 describes the power lines on the expansion bay connector. The +5V line is controlled by the /MB_PWR signal from the KeyLargo IC.

Table 4-5 Power lines on the expansion bay connector

Signal name	Signal description
GND	Ground.
+5V	5 V power.

The power lines are equipped with current-limiting devices to protect the computer from damaged modules or short circuits. The current limit is between 1.8 and 2.0 A.

IMPORTANT

For thermal reasons, the continuous power dissipation in the expansion bay must not exceed a total of 5 W.
