4.Replace the back panel and the three screws across the top edge.

5.Reconnect the main unit to the monitor, the keyboard, the printer, and any other peripherals you have.

6.Turn the main unit so the front faces you and place the monitor back on top of the main unit, if that is where you keep it.

7.Check to be sure the power switch on the main unit is off. Then reconnect the power cable to the AC input on the back panel and to an electrical outlet.

Post-Installation Adjustments

After you install an option card, you may need to change some DIP switch settings to match your new system configuration. See “Setting the DIP Switches” in Chapter 1 to find out which DIP switches (if any) you need to reset.

Then use the MS-DOS SETUP program to update your system’s configuration information. For example, if you add a hard disk, you need to tell the operating system that the additional drive is available. See your MS-DOS (or other operating system) manual for instructions.

Also complete any additional instructions in the option card manual.

Removing an Option Card

Before you remove an option card, turn off, unplug, and disconnect your system components. Be sure to detach any cable connected to the card. Then remove the main unit’s back panel and cover.

To take out the card, remove the screw on the metal retaining bracket and pull the card straight up and out of the connector. Then carefully wrap the card, preferably with the original packing materials, and place it inside its box for safe storage.

Replace the metal plate and retaining screw at the back of the empty option slot. Then replace the main unit’s cover. Snap the plastic access slot cover onto the back panel and then attach the back panel to the computer.

If necessary, reset the DIP switches on the main unit. Also, if you used the MS-DOS SETUP program to change some operating system settings for the option card, you need to change these settings back to their original values.
