5 MB Hard Drive (260-1130) Installation Faxback Doc. # 5067 ┌──────────────────────────────────────────────────────────────────┐ │For Model I Instructions, see Faxback Document # 5065, "ADDENDUM" │ └──────────────────────────────────────────────────────────────────┘ CONNECTING YOUR PRIMARY DRIVE TO A MODEL III Be sure all power is OFF. NOTE: Master unit does not come with Data Out connectors. These are supplied with each secondary unit and require installations. Locate the hard disk expansion cable. Connect one end to the I/O bus card edge of your Model III. Be sure the cable exits the rear of the computer so that it won't bind. Connect the opposite end of this cable to the COMPUTER IN connector, located on the rear panel of the primary drive. Connect the power cord to the primary drive. Plug the other end into an appropriate AC power source. CONNECTING SECONDARY DRIVES The secondary drives are connected to the computer via the primary disk drive. The drives must be stacked with the primary drive on top of the secondary drives. Locate the secondary hard disk expansion cable. Connect one end to the Control In jack of the secondary drive and the other end to the Control Out jack and the previous drive in the chain. If you have only two hard disk drives, this connector connects to the primary drive. If you have another secondary drive, connect the second secondary hard disk expansion cable to the Control Out jack and the other end to the Control In jack of the next drive in the chain. Locate the data cable. Connect one end to the appropriate data jack (A for the first secondary drive, B for the second, and C for the third). Connect the other end to the Data In jack on the secondary drive. MODEL III SYSTEM POWER-UP 1. Make sure all power is OFF and all floppy diskette drives are empty. 2. Turn on all peripheral equipment (such as a printer or additional floppy diskette drives). 3. Turn on the primary hard drive by turning the POWER KEY clockwise. This also turns on all secondary drives. All secondary drives' power lights should come on. 4. Turn the computer ON. 5. Insert either the INITIALIZATION diskette of the START-UP diskette in floppy Drive 0. 6. Press RESET. In a few seconds the screen shows a large LDOS logo. If the LDOS logo does not appear, repeat the above steps, making sure you inserted the diskette properly. 7. The screen then shows this prompt: LDOS Ready Since you've not yet initialized your Hard Disk System, the computer is now operating as a Floppy Disk System, the only way it can operate until you initialize it. If you've initialized the Hard Disk System, you can remove the START-UP diskette. You only need it to start up or reset. To operate the system for floppy disk only, hold down the key and press the RESET button. (You must keep the key down until LDOS Ready appears.) MODEL III SYSTEM POWER DOWN 1. The LDOS Ready prompt should be the last line on your screen. If not, press [ENTER] or exit your program so that it appears. 2. Remove all floppy diskettes from their drives. 3. Turn off any peripheral equipment. 4. Turn off the hard disk drive by turning the power key on the primary drive counterclockwise. This turns off all the drives. 5. Turn off the computer.
