Option Cards
Your computer has five option slots, each of which
can
accommodate one card of the following types:
32-bit EISA bus master option card
16-bit ISA compatible option card
8-bit ISA compatible option card.
Before you install an option card, check all the power
requirements given in the documentation that came with the
card. Make sure that the power required by the card does not
exceed the power limit for its slot, and that the total power for
all the cards does not exceed the power limit for all five slots.
The table below lists the power limits.
Option slot power limits
Maximum current +5 Volts + 12 Volts -5 Volts -12 volts
For each slot 7 Amps 1.5 Amps 0.5 Amps 0.5 Amps
For all five slots 16 Amps 3 Amps 0.5 Amps 0.5 Amps
Caution
Although your power supply is protected against excessive
power loads, you could still damage the main system board
if you install an option card that draws more power than the
limits shown in this table.
