CHIP_FAIL is an alarm indicating failure of an important chip. PARA and PARA represent the number of the failing chip, and PARA and PARA represent the number of clock-type failure. The PARA of the CHIP_FAIL above is 0f, indicating the SA527 chip detects loss of its 2M master clock (namely the MCLK clock), and PARA is 0xff, indicating all the eight pieces of SA527 of the PQ1 board detect loss of the MCLK clock, so the 2M clock of the PQ1 board has deteriorated, and the 2M crystal oscillator stops oscillating.
The E1LOC alarm is detected by SD538. SD538 tests the 2M clock extracted from the service sent by SA527. If the 2M master clock of SA527 is lost, it is impossible to extract clock from the service. Therefore SD538 reports E1LOC.
