You can also select the source of the +5 V Standby voltage. If you source the
+5 V Standby voltage from the +5 V external supply (monitor backup power
supply connector), then the external supply will provide the backplane with the
+5 V external voltage (1 A maximum). If you source the +5 V Standby voltage
from the 25-pin connector, you must provide the +5 V to pins 8 and 21 of the
25-pin connector. The default jumper setting is to provide the voltage from the
external source (+5 V external power supply).
The enhanced monitor can answer to the slot 1 or slot 12 MODID line for the
configuration manager. The default position is slot 12.
In order to flash the enhanced monitor board with the latest firmware, you need
to install a firmware loader jumper at the location shown in Figure 2--7.
