    Block Diagram Polyswitches (Resettable Fuses) The MVME1600-001 and MVME1600-011 base boards draw fused +5Vdc, +12Vdc, and –12Vdc power from the VMEbus backplane through connectors P1 and P2. The 3.3Vdc power (used by the ISA Super I/O device on the base board, and by the PM603 or PM604 processor/memory mezzanine) is derived on-board from the +5Vdc.
  • Page 79 Functional Description Note Because any device on the SCSI bus can provide , and because the LED monitors the status TERMPWR of several voltages, the LED does not directly indicate the condition of any single fuse. If the LED flickers or goes out, check all the fuses (polyswitches).
  • Page 80: Speaker Control

    Block Diagram Speaker Control The MVME1600-001 base board supplies a signal to SPEAKER_OUT the 14-pin combined LED-mezzanine/remote-reset connector, J1. When J1 is used as a remote reset connector with the LED mezzanine removed, the signal can be cabled to an SPEAKER_OUT external speaker to obtain a beep tone.

MPC604 boards have double-wide front panels to accommodate a heat sink on the PowerPC604 that protrudes into the adjacent VME slot.

    (together with a PM603 or PM604 processor/memory mezzanine, an LED mezzanine, and an optional PCI mezzanine card) plugs into the base board to make a complete MVME1603 or MVME1604 single-board computer. See Figure 1-11. RAM104 modules of 8, 16, 32, or 64MB are available for memory expansion.

    Functional Description MVME760 Transition Module The MVME760 transition module (Figure 1-4) is used in conjunction with the MVME1600-001 base board. The features of the MVME760 include: A parallel printer port An Ethernet interface supporting both AUI and 10BaseT connections Two EIA-232-D asynchronous serial ports (identified as COM1 on the front panel) COM2...

    Block Diagram MVME712M Transition Module The MVME712M transition module (Figure 1-6) and P2 adapter board are used in conjunction with the MVME1600-011 base board. The features of the MVME712M include: A parallel printer port (through the P2 adapter) An Ethernet interface supporting AUI connections (through the P2 adapter) Four EIA-232-D multiprotocol serial ports (through the P2 adapter)
