4.3.2 TO REPLACE BOARDS AND CABLES
1. Connect the UIB cable to motherboard connector JP20.
2. Replace the power supply (see page 4-42).
3. Replace the following cables as described:
• Connect the 4-pin power cable to the CD-ROM drive.
• Connect the CD-ROM drive ribbon cable from the CD-ROM drive to the SIDE (Sec-
ondary IDE) connector on the motherboard.
• Connect the HDD ribbon cable from the HDD to motherboard connector PIDE (Pri-
mary IDE).
Make sure to connect the longer end of the HDD ribbon cable (with the
blue connector) to the HDD. Also, make sure not to switch the CD-ROM
and HDD ribbon cables. The CD-ROM ribbon cable has 40 wires; the HDD
ribbon cable has 80 wires.
• Connect the 20-pin power cable to motherboard connector J14.
• Connect the back panel fan cable to motherboard connector FAN2.
• Connect the front fan cable to motherboard connector FAN3.
4. Replace the following boards in their motherboard connectors:
• Copier interface board in motherboard connector PCI1 (see page 4-18)
• Optional Token Ring board in motherboard connector PCI2 (if this option is present).
• Optional parallel I/F adapter in motherboard connector PCI3 (if this option is presert).
When installing boards, make sure that the board connectors are properly
aligned with their connectors on the motherboard.
5. Make sure all board mounting bracket screws for boards occupying back panel slots are
secured. Press down firmly on the top of the board as you insert each screw.
Make sure unused slots have slot covers installed. Uncovered slots reduce
the air flow and could cause the iR-M2 to overheat.
6. Reassemble the iR-M2 (see page 4-13) and verify its functionality (see the connection
verification steps described on page 4-15).
