The power connection is easy since it only fits one way and a latch is available to secure it when fully inserted. The signal cable is tricky because the cable fits in both orientations as well as shifted one direction or the other. The signal cable also has no latch to determine when full insertion is made. Align the red stripes of the signal and power cables so that they face each other. Carefully insert the connector while visually watching the progress so that proper alignment and insertion is made. Be careful, bent pins are very difficult to straighten.

The 5.25” device cage can be removed for mounting or unmounting devices. With the 3.5” device cage and front panel removed, the 5.25” device cage can be pulled out from the chassis. For proper mounting of your 5.25” device, use this picture as a reference otherwise trial and error is necessary to make it flush with the front panel opening. Screw holes are available on each side for securing devices. 5.25” device bay 1 5.25” device bay 2 5.25” device bay 3 5.25” device cage with a CD-ROM in its topmost bay 20 AP100 Hardware Reference Guide II. System Components CD-ROM Disk Drive The CD-ROM disk drive mounts only in the 5.25” device cage and requires signal and power connections like that of IDE hard disk drives. The power and signal cable is straightforward with connectors designed to only fit correctly. The red stripe of the signal and power cables should face each other. NOTE: A CD-ROM audio cable is also provided in case you install an audio card. The only function of the audio cable is to allow you to direct the CD audio out signal to your audio card. Data signals travel through the IDE cable. Red stripe of signal cable Red stripe of power cable Expansion Cards Expansion cards can be easily installed just like any standard PC computer. Up to 4 PCI or 2 ISA (1 slot is shared allowing a maximum of 5 cards at one time) cards can be installed. One AGP slot is also available for a high-end graphics card. Expansion Card Installation Procedure: 1. Follow the static precautions described in the front of this manual. 2. Switch off your system and all peripheral devices and remove the main power cord. 3. Remove the side panel to the chassis. 4. Find an unused expansion slot on the motherboard and unscrew the metal cover plate from the slot and put the screw to one side. 5. Ensure the jumpers (if any) are correctly set on your expansion card 6. Align the card’s connector with the expansion slot on the motherboard and gently lower and push the card into the free slot. 7. Secure the card to the expansion slot with the screw you removed from the metal plate. 8. Attach cables or wires if necessary. 9. Reinstall the side panel if no other work is needed inside the chassis. CD audio output CD-ROM drive connections II. ComponentsCD-ROM / Expansion AP100 Hardware Reference Guide 21 II. System Components II. ComponentsSCSI Information SCSI Information SCSI Connections Your server can support up to 15 user installed single-ended SCSI devices. Be sure to include both internal and external SCSI devices in your device setup. Each SCSI device (both internal and external) must have a unique address (or SCSI ID). Check your SCSI device documentation for instructions. Be sure to record all SCSI addresses so that you can prevent SCSI address conflicts. SCSI Termination SCSI devices are connected together in a “chain” by cables. Internal devices connect to the motherboard with a 50 pin or 68 pin flat ribbon cable. External SCSI devices may be connected using an external SCSI connector or SCSI card with an external connector. If there are more than one internal or external devices, additional devices are connected with cables to form a “daisy chain.” Terminating the devices on the ends of the SCSI Bus “chain” is necessary for SCSI devices to work properly. SCSI devices normally come with its termination enabled by jumpers or dip switches. You must disable these termination for devices in between the SCSI chain. Ultra2 devices do not have a termination jumper and must be terminated using a terminator on the SCSI cable. The terminator must always be on the end of the cable which means that you cannot connect a device on the last connector. SCSI ID Jumpers All SCSI devices, including this motherboard with onboard SCSI, must have a SCSI identification number that is not in use by any other SCSI device. There are sixteen possible ID numbers, 0 through 15. The SCSI ID serves two purposes: • It uniquely defines each SCSI device on the bus. • It determines which device controls the bus when two or more devices try to use it at the same time. SCSI IDs on one channel do not interfere with the IDs on another channel. You can connect up to 15 SCSI devices to this motherboard. Yo...
