RELIANCE 45C314 Redundant output module

Similarly, the VMEchip2 provides an input signal and a control bit to initiate a local reset operation. By setting a control bit, software can maintain a board in a reset state, disabling a faulty board from participating in normal system operation. The local reset driver is enabled even when the VMEchip2 is not the system controller. A local reset may be generated by the RESET switch, a power-up reset, a watchdog timeout, a VMEbus SYSRESET*, or a control bit in the GCSR. Note For an MVME162 without the VMEbus option (i.e., with no VMEchip2), the LCSR control bit is not available to reset the module. In this case, the watchdog timer is allowed to time out to reset the MVME162.

Front Panel Indicators

nt Panel Indicators (DS1 - DS4) There are eight LEDs on the MVME162 front panel: FAIL, STAT, RUN, SCON, LAN, FUSE, SCSI, and VME. 

❏ FAIL LED (red). Lights when the BRDFAIL* signal line is active. Part of DS1. 

❏ STAT LED (yellow). Driven by the MC68040 status lines on the MVME162. Lights when a halt condition from the processor is detected. Part of DS1. 

❏ RUN LED (green). Lights when the local bus TIP* signal line is low. This indicates one of the local bus masters is executing a local bus cycle. Part of DS2. 

❏ SCON LED (green). Lights when the VMEchip2 in the MVME162 is the VMEbus system controller. Part of DS2.

❏ LAN LED (green).

 Lights when the LAN chip is local bus master. Part of DS3.

 ❏ FUSE LED (green). Lights when power is available to the transceiver interface (the MVME162 supplies +12V power to the LAN Ethernet transceiver interface through a fuse). Part of DS3. 

❏ SCSI LED (green). Lights when the SCSI chip is local bus master. Part of DS4. 

❏ VME LED (green). Lights when the board is using the VMEbus (VMEbus AS* line asserted by the VMEchip2) or when the board is accessed by the VMEbus (VMEchip2 is the local bus master). Part of DS4.
