Honeywell 51401583-100 EPNI Card Enhanced Process Network Interface Board
The EPNI and PNM boards are controller boards which interface the bus and processor in a similar way as the controller boards listed in Section 3.3.2. First, check the SELF TST/ERR light (red; should be out) and PASS MOD TEST light (green; should be on) on the EPNI and PNM boards.
The SELF TST/ERR light (red) is driven by a microprocessor on the EPNI board. If it is on, check for the following causes:
• There was a hardware failure on the EPNI board.
• A problem was detected on-line (for instance, there may have been a EPNI local RAM parity error or a duplicate address may have been detected).
• The node was shut down (stunned) due to a watchdog timeout.
• The number of raw errors detected exceeded a pre-set threshold, causing the software on the EPNI board to enter the failed state.
51401583-100 image is for reference only product style, specific data of manufacture and product version, please refer to the actual product delivery!
If the state of the SELF TST/ERR light and PASS MOD TEST light are correct, continue with this instruction. Under normal system operating conditions the following indicators and connections are present on the EPNI/PNM boards.
• Red LEDs are out.
• Green LEDs are lit.
• Yellow LEDs either blink on and off (indicating traffic) or stay on (heavy traffic).
• The ribbon cable which connects between the PNM and PNI I/O paddleboards is firmly fastened in place.
• The two mini-coax cables which connect between the PNM board and the PNM I/O paddleboard are firmly fastened in place.
• The TX yellow indicators blink (or remain steadily on) as data traffic is sent. The two indicators on the EPNI and PNM boards monitor identical circuits and blink or light in unison. Transmit data is sent simultaneously on both cables.
• One of the RCVE CABLE yellow indicators on the PNM board blinks (or remains steadily on) as data traffic is received. The UCN signal is first received on one cable for about 15 minutes, then the receiver is switched to the other cable to maintain confidence.
