Option Cards

An option card is a circuit board you install in your computer to add a particular function. Most option cards contain a device, such as a modem, or provide an interface, such as a serial port.

Your computer has six 16-bit option slots, each of which 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.
