There is a total of four OIDs that make up a 128 bit wide field, with each bit representing a particular fault. Each of the OIDs contains 32 bits. If no bits are set (i.e. the four OIDs return 0), no fault is present.
fault[0].flt |
Bits 0 to 31 |
fault[1].flt |
Bits 32 to 63 |
fault[2].flt |
Bits 64 to 95 |
fault[3].flt |
Bots 96 to 127 |
The table lists known faults, if the bit is set in the devices output then the fault is currently present:
