The Epson® PowerSpan® computer is a powerful, versatile system ideally suited for use as a network file server. It incorporates the latest EISA (Extended Industry Standard Architecture) technology in a convenient tower design. Its exceptional features and flexibility enable you to use the most advanced peripheral devices and software while maintaining full compatibility with ISA technology.
The built-in interfaces let you connect basic peripheral devices directly to the computer, leaving the expansion slots for optional devices such as a SCSI adapter and a networking card. You can also install a variety of other options, such as diskette drives, hard disk drives, a tape drive, or a SCSI subsystem. You can upgrade your system microprocessor by replacing the removable CPU card with an Intel Pentium® CPU card or by installing an Intel P24T OverDrive™ processor on the existing CPU card.
How to Use This Manual This manual explains how to set up, configure, and operate your computer, as well as how to install optional equipment. It does not cover your operating system; see your operating system manual for instructions on installing and using it. Although you should be sure to follow the steps in Chapters 1, 2, and 3 to set up and configure your system, you do not need to read everything in this book. See the following chapter summaries to find the sections you need.
Where to Get Help If you purchased your computer in the United States, Epson America provides local customer support and service through a nationwide network of authorized Epson dealers and Service Centers. Epson also provides support services through the Epson ConnectionSM at: (800) 922-8911.
Chapter 1 Setting Up Your System This chapter describes how to set up and start using your computer system for the first time. before you set up your system, be sure to read the “Important Safety Instructions” at the beginning of this manual. Preparing to Set Up Your System It is important to choose a safe, convenient location for your system that provides the following: A flat, hard surface. Place the computer on an anti-static mat if the surface is carpeted. Good air circulation.
If the power cord supplied with your system is not compatible with the AC wall outlet in your region, obtain a suitable power cord that meets the following criteria: The power cord must be rated for at least 125% of the current rating of the AC voltage system. For more information, refer to Appendix B. The power cord connector that plugs into the wall outlet must terminate in a grounding-type male plug designed for use in your region.
2. The keys for the front panel door lock are taped to the inside of the door. Open the door to remove the keys. (It might be a little hard to open the door the first time.) 3. Install any optional equipment you want to add to your computer, such as disk drives, memory modules, or EISA option cards. You may not want to install any ISA option cards yet (unless you will use an ISA card to control your monitor). See “Installing Optional Equipment,” on page 1-5. 4.
Setting the Voltage Selector Switch Your system is powered by a 230 watt power supply. The power supply voltage is controlled by a voltage selector switch on the computer’s back panel that may be set to 115 VAC or 230 VAC. The computer is shipped with the voltage selector switch set to 115 VAC. This setting is appropriate for line source voltages between 100 and 120 VAC. This is generally the appropriate setting if you will use the computer in North America or Japan.
Caution Before you turn on the power to your system, you must be sure the voltage selector switch is set to the appropriate setting for the electrical power source in your location or you will seriously damage your system. To change the voltage selector switch setting, insert the tip of a ball-point pen or a similar tool into the dimple on the switch. Then slide the switch to the right to select 115 VAC or to the left to select 230 VAC.
If you plan to install any ISA cards that came with their own CFG files, you should install them after you have connected the necessary peripheral devices and run the computer’s EISA Configuration utility. This allows you to add the CFG file information to your configuration so the program can give you the card’s correct jumper and switch settings. Then you can set the switches and jumpers and install the card. See the documentation that came with your card(s) for information.
Before connecting the peripheral devices, make sure the power buttons or switches on the computer and all peripheral devices are turned off. Then follow these steps to connect the peripheral devices: 1. If necessary, insert the mouse cable connector into the mouse port on the back panel. Caution Although the keyboard and mouse ports appear to be identical, you cannot use them interchangeably. Be sure to plug the keyboard and mouse into the correct ports. 2.
Turning On the System Read the following safety rules to avoid damaging the computer or injuring yourself: 1-8 cl Do not connect any power or peripheral device cables when the computer’s power is on. cl Never turn on the computer while a protective card is in a 5.25-inch diskette drive. cl Never turn on the computer when its cover is off. cl Never turn off or reset your computer while a disk drive light is on. This can destroy data stored on the disk.

Guide the bracket over the edge of the CPU card and slide the slotted end toward the hole in the back of the computer. 5.
Installing an Option Card This section explains how to install an option card in one of your computer’s eight EISA bus master expansion slots. It usually does not matter which slot an option card occupies as long as the card fits in the slot. For example, if you have an 8-bit card with an additional tab along the bottom, it will not fit in any of the option slots in your computer. Before you install an option card, see if you need to change any jumper settings on the main system board.
3. Unpack the option card and adjust any switches or jumpers on it, if necessary. (Check the option card instructions.) When you handle the card, be careful not to touch any of its components or the gold connectors. If you need to set it down before you install it, place it gently on top of its original packing material with the component side facing up. Keep the packing materials in case you remove the card later.
Once the connectors reach the slot, push the card in firmly (but carefully) to insert it completely. You should feel the card fit into place. If it does not go in smoothly, do not force it; pull the card all the way out and try again. 5. Secure the end of the card to the computer with the retaining screw. Note If you installed a high-resolution graphics adapter card that connects to a VGA feature connector, see “Using the VGA Feature Connector” on page 6-9 for further instructions.

Cl Make sure you enabled the built-in controller and selected the correct diskette drive type(s) when you ran the SETUP program or the EISA Configuration utility. See Chapters 2 and 3 for instructions. Cl If you cannot write to the diskette, make sure jumper E0291 is set to position 2-3 to enable writes to the diskette drive.
Hard Disk Problems If you think there is something wrong with your hard disk, see the suggestions below. you have problems with a newly-installed drive. Ll If your dealer installed the drive, consult your dealer about the problem. c3 If you installed the hard disk yourself, make sure you carefully followed all the instructions in Chapter 7. Review the procedures and check all the cable connections to make sure you installed it correctly.
You notice a reduction in hard disk performance. Cl The data on the disk may have become fragmented. You may want to back up all your data and then use a disk compaction utility to reorganize the files on your disk. Contact your dealer for information. U If you cannot access data on your hard disk or you are receiving read/write errors, the disk may have a physical problem. If the problem persists, contact the dealer from whom you purchased the drive.
Printer Problems CI Make sure the printer has power and is properly connected to the computer. (Also, be sure your printer has paper in it.) Cl Check the printer manual for the printer’s correct DIP switch or control panel settings.
