Alarms & troubleshooting

SYS_COMM_DOWN (SNMP_AGENT_TIMEOUT / Central OSS SNMP Gateway Disconnect)
M830B front panel Ethernet LINK/ACT LED unlit or off; local LCD operational but remote OSS unreachable
Ethernet cable detached, uplink switch port VLAN misconfiguration, or expired SNMPv3 USM privacy/auth keys
1. Navigate LCD menu to `Network Setting`, verify static IP, subnet mask, and gateway address match network allocation; 2. Reseat and test RJ45 Ethernet patch cord, check link negotiation on upstream managed switch port; 3. Re-push SNMPv3 SHA/AES authentication credentials from OSS portal and restart network stack via controller utility.
CAN_BUS_ERROR (CAN_COMM_INTERRUPT / CAN Bus Telemetry Packet Loss)
Front panel ALARM LED solid red; LCD alerts that all rectifier live metrics are frozen/offline
120-Ohm CAN bus terminal balancing resistor missing/damaged causing signal echo, or severe EMI interference
1. Measure DC impedance across CAN_H and CAN_L lines; reading should be approximately 60 Ohms (two 120 Ohm resistors in parallel); 2. Check M830B CAN RJ45 jumpers and ensure backplane DIP termination switch is set to ON; 3. Unseat rectifiers one-by-one to identify if a single damaged transceiver is pulling the CAN differential bus low.
BATT_CAP_LOW (BATTERY_SOH_DEGRADED / Battery State of Health Depleted)
Yellow OBSERVATION LED lit on M830B; controller routine calculation alerts remaining runtime falls below SLA threshold
Battery bank exceeded operational lifespan, dried out or sulfated under chronic high ambient heat, capacity dropped <80%
1. Trigger controlled 10% depth online discharge test routine from M830B maintenance menu; 2. Measure cell conductance/internal impedance with battery tester, tag degraded cells with >20% impedance drift; 3. Recalibrate battery nominal capacity rating in controller config and request complete battery string replacement.
