ICS TRIPLEX T3500 Displacement speed clamp

There are six LEDs on the MVME2603/2604 front panel: CHS, BFL, CPU, PCI, FUS, and SYS. 

❏ CHS (DS1, yellow). Checkstop; driven by the MPC603/604 status lines on the MVME2603/2604. Lights when a halt condition from the processor is detected. 

❏ BFL (DS2, yellow). Board Failure; lights when the BRDFAIL∗ signal line is active. 

❏ CPU (DS3, green). CPU activity; lights when the DBB∗ (Data Bus Busy) signal line on the processor bus is active. 

❏ PCI (DS4, green). PCI activity; lights when the IRDY∗ (Initiator Ready) signal line on the PCI bus is active. This indicates that the PCI mezzanine or carrier board (if installed) is active. 

❏ FUS (DS5, green). Fuse OK; lights when +5V DC, +12V DC, and –12V DC power is available from the base board to the transition module and remote devices.

Polyswitches (Resettable Fuses)

 The MVME2603/2604 base board draws fused +5V DC, +12V DC, and –12V DC power from the VMEbus backplane through connectors P1 and P2. The 3.3V DC and the core processor voltage power is supplied by the on-board +5Vdc. The following table lists the fuses with the voltages they protect.

In MVME712M I/O mode, the yellow DS1 LED on the MVME712M also signals the availability of +12V DC LAN power, indicating in turn that polyswitch R34 is good. If the Ethernet transceiver fails to operate, check polyswitch R34.

I/O Power 

The MVME2603/2604 base board furnishes +12V DC and (in MVME761 I/O mode) –12V DC power to the transition module through polyswitches (resettable fuses) R34 and R28 respectively. These voltage sources power the serial port drivers and any LAN transceivers connected to the transition module. Fused +5V DC power is supplied to the base board’s keyboard and mouse connectors through polyswitch R30 and to the 14-pin combined LED-mezzanine/remote-reset connector, J1. The FUS LED (DS5) on the MVME2603/2604 front panel illuminates when all three voltages are available.
