Hello, everyone, we have a hirschmann switches automatically restart, now want to determine the cause of the restart, so two found in the log:

04186:17.01.14 07:54:10: HIGH S_switch_WORKAROUND_RESET StatsTask, marv_stats. C, 1620
. B6, 00000024000011 7000 000 00000000... $...
04181:17.01.14 07:54:04: MIDDLE S_phy_WORKAROUND_RESET StatsTask, marv_stats. C, 1599
. 00000024000011 7000000 1000000 0... $...
We then tried cold restart and hot restart by configuration software, a warm restart log is
00239:06.05.18 11:06:59: EVENT S_watson_SYSTEM_RESET_WARM SNMPTask, SRC/Watson. C, 1775
. E4d50 0006 bb48, 534, 5461736 b, 00000000... HSNMPTask...
When the cold restart log
00115:01.01.13 01:02:37: EVENT S_watson_SYSTEM_RESET_COLD SNMPTask, SRC/Watson. C, 1779
. 00026877534 e4d50, 5461736 b, 00000000.. HwSNMPTask...
Also tried out electricity to restart, restart when power supply drop, lost all before log is,
Repetition is S_phy_WORKAROUND_RESET and S_switch_WORKAROUND_RESET, less hersman information on the Internet, excuse me, does anyone know, these two log is what mean?
I said Google to S_switch_WORKAROUND_RESET connect full-duplex equipment in half duplex on port, so, the mouth of the problem is that we are all Auto, S_phy_WORKAROUND_RESET is what mean?
Thank you first!
