Option Cards Your computer has six standard option slots: five 16-bit slots and one 8-bit access slot. Each slot can accommodate an option card. You can buy option cards from authorized Epson dealers as well as other vendors. Before you install an option card, check the power requirements given in the card's documentation. 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 limits for all six slots. The table below lists the power limits. Option slot power limits Maximum current +5 volts For each slot 7 Amps For all six slots 16 Amps + 12 Volts 1.5 Amps 3 Amps -5 Volts and - 12 Volts 0.5 Amps 0.5 Amps Caution Although the computer's 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 the table. This section explains how to install option cards in your computer. Later on, you may need to remove an option card to access jumpers; if so, see "Removing an Option Card" on page 6-12 for instructions. 6-8 Installing and Removing Options
