Epson 4000 - Manual (Page 62)

Check the components on your option card and the system
board before deciding which slot to use. Make sure that no
components are touching or obstructing other cards or cables.
Caution
Make sure the power requirements for the option cards you
install do not exceed the power supply limitations. See your
option card manual(s) for the power requirements. Then
check Appendix A for the option slot power limits.
Before you install an option card, see if you need to change any
jumper settings on the system board. For example, if you install
a SCSI hard disk drive, you may need to change jumper J35 to
disable the IDE hard disk drive controller. See page 4-6 for
more information on jumpers.
Note
You cannot install a video display card in this system.
Refer to the illustrations below and follow these steps to install
an option card:
1. If you are using a 16-bit option slot, go on to step 2. If you
are using an 8-bit slot near the power supply, you need to
move the power supply before you can remove the metal
slot cover.
