Each bit of this value set to '1' indicates a specific fault in the module. Octets are numbered in the order in which they appear in the PDU. Bits are numbered from the most-significant leftmost bit in the octet (bit 0) to the least-significant rightmost bit (bit 7). Cajun numbering continues across octets, so that octet 1 bit 0 is called bit 8 in the Cajun scheme. That number is also shown below, with the octet value for each single bit set. Octet 0 high-order 4 bits show fan status. Octet 0 low-order 4 bits show temperature status. Octet 1 shows power supply status. Octet 2 shows other alarms. Cajun Octet Octet bit# /bit# value Meaning 0 0/0 0x80 Multiple fan warning: at least two fans have been operating at less than 90% of their nominal speed for 5 minutes or more. This may be an early warning of overheating. 1 0/1 0x40 PSU fan brief failure warning: the power supply fan has been operating at less than 90% of its nominal speed for 10 minutes or more, but less than 15 minutes. This may be an early warning of overheating. 2 0/2 0x20 PSU fan prolonged failure warning: the power supply fan has been operating at less than 90% of its nominal speed for 15 minutes or more. This may be an early warning of overheating. 3 0/3 Unused. 4 0/4 0x08 Temperature warning: cmgCpuTemp has exceeded its warning threshold. 5 0/5 0x04 Temperature warning: cmgDspTemp has exceeded its warning threshold. 6 0/6 Unused. 7 0/7 Power On Status Test failure -NCE, QUICC test failures on power up 8 1/0 0x80 The +5.1 v power supply to the MG processor is out of range. 9 1/1 0x40 The -48 v power supply to the media modules is out of range. 10 1/2 0x20 The +3.3 v power supply to the VoIP complexes is out of range. 11 1/3 0x10 The +1.58 v power supply to the DSP units is out of range. 12 1/4 0x08 The +2.5 v power supply to the 8260 processor is out of range. 13 1/5 0x04 The -48 v auxiliary power supply to the endpoints is out of range. 14 1/6 0x02 The +12 v power supply to the fans is out of range. 15 1/7 Unused. 16 2/0 0x80 Clock synchronization signal is lost. 17 2/1 0x40 Clock synchronization signal warning.
