1 1 Accessing the System This chapter lists hand tools and describes servicing restrictions, opening the base unit, avoiding electrostatic discharge, removing and attaching the face plate, and closing the base unit. This system features a telescoping chassis that provides increased serviceability and access to internal components. The telescoping section, to which the system board is mounted, is secured by five screws and slides out from the rear.
2 Protecting Against Electrostatic Discharge Sensitive components inside the base unit can be damaged by static electricity. To protect against this possibility, take the following precautions when working with the system’s internal components. u Touch the bare metal of the base unit to ensure it and your body are at the same electric potential. u Handle all printed circuit boards as little as possible and by the edges only. Leave new parts in their protective packaging until you install them.

50 Address Resources for MSMT353 and MSMT359 DMA Channels The system board uses Direct Memory Address (DMA) channels to exchange data without accessing the CPU. Some channels are assigned for specific use by the system, as defined below. Each DMA channel or MSMT359 appropriates full 32-bit processing. For an ISA bus, channels 0 through 3 are 8-bit and channels 4 through 7 are 16-bit channels.

For PC-AT architecture compatibility reasons, the PCI interrupts are routed to the ISA interrupts within the ISA bridge. The assertion of a PCI interrupt concludes in an ISA interrupt being asserted.
52 Each PCI slot on the riser card has four available or MSMT359 interrupt lines: INTA, INTB, INTC, and INTD.

73 9 Peripherals This chapter provides information on configuring peripherals in all rack-mount systems. Up to six SCSI devices may be added to the system drive bays. The following table defines the standard drive locations when drives are factory installed.
74 SCSI CD-ROM Drive (CDSK178) The following figure shows the back of the CD-ROM drive. SCSI Connector Audio Connector Mode Select Header Terminator Sockets Power Connector u The audio connector uses MCBLZ630 and connects to J22 on the system board. Refer to Chapter 5 or 6 for the cable pinout. u The SCSI connector uses MCBL234A and connects to the riser card. u Settings for mode select header, which sets SCSI ID, parity, and other drive functionality are printed on the CD-ROM drive.
75 SCSI ID selection is defined in the following table. Each disk drive has a connector which uses jumpers to set the SCSI ID. Where Seagate uses ID1, ID2, and ID4 to identify how to set the SCSI ID, Conner uses 0E1, 0E2, and 0E3. SCSI ID ID1/0E1 ID2/0E2 ID4/0E3 0 1 2 3 4 5 6 Off On Off On Off On Off Off Off On On Off Off On Off Off Off Off On On On u The SCSI connector uses MCBL234A and connects to the riser card.
76 CDSK094 (2 GB) The following figure shows the jumper connectors J6 and J2 on the Seagate 2 GB disk drive. SCSI ID selection uses the ID1, ID2, and ID4 jumpers on connector J6. To disable SCSI termination, remove the TE jumper from connector J2. ID1 ID2 J6 ID4 SCSI Connector Pin 1 J2 Power Connector oooooooo oooooooo TE TP CDSK098 (4 GB) The following figure shows the jumper connector J5 and SCSI terminator sockets on the Conner 4 GB disk drive.
77 CDSK123, CDSK164, CDSK165, CDSK166, CDSK167 (4 GB) The following figure shows the jumper connectors J6 and J2 on the Seagate 4 GB and 9 GB disk drives. SCSI ID selection uses the ID1, ID2, and ID4 jumpers on connector J6. To disable SCSI termination, remove the TE jumper from connector J2. ID1 ID2 J2 J6 oooooooo oooooooo TE ID4 SCSI Connector Pin 1 Power Connector Floppy Disk Drive (CDSK146) The following figure shows the cable connectors on the back of the floppy disk drive.
78 Combo Drive (MESAM86) The following figure shows the cable connectors on the combo drive MESAM86. Converter Connector Power Connector Floppy Connector J2 J5 J4 J6 J3 ISA Bus Connectors u The power connector uses power supply cable P9 from the power supply. Refer to Chapter 10, “Power Supply and Fans,” for the cable pinout. u The ISA bus connector J3 uses MCBL084A and connects to J33 on the MSMT353 system board.
79 EIDE CD-ROM Drive (CDSK177) The following figure shows the back of the EIDE CD-ROM drive for the TDZ-425 RAX system. Install jumpers as shown. Audio Connector Mode Select 2 IDE Connector Mode Select 1 Power Connector u The power connector uses power supply cable P6 from the power supply. Refer to Chapter 10, “Power Supply and Fans,” for the cable pinout. u The audio connector uses MCBL122A and connects to J22 on the system board. Refer to Chapter 6 for the cable pinout.

81 10 Power Supply and Fans This chapter describes the 539-watt power supply and cooling fans used in all rack-mount systems. Differences among systems are noted. Power Supply (MPWS145) MPWS145 is a 539 watt autoranging supply, that switches between 90-132 VAC or 180-264 VAC, depending on the location. The input frequency is 47-63 Hz, single phase. At full load, the power supply has a minimum efficiency of 65 percent.
82 Cable Connectors The following table shows the cable connectors from the power supply that connect to the riser card and to the devices in the system.

NOTE Airflow in the system is front to back. Arrows on the fan indicate airflow direction and rotation.
84 Vertical Bay Disk Drive Fan (MCBLY690) The disk drive fan is MCBLY690, an 80 mm fan mounted to the vertical drive bay. The fan power cable connects to MCBLZ660, which connects to J69 on the MSMT353 or MSMT359 system board or connects to MCBL284A and to J64 on the MSMT378 system board. Internal Bay Disk Drive Fan (MCBLY690) The disk drive fan is MCBLY690, an 80 mm fan mounted to the internal drive bay. A hole on the back of the chassis provides access to the fan screws and grille.
