The switch rebooted after a System Failure. After it rebooted we looked at the log on the switch and it doesn't show any messages in the log for 6 days. Here is a little cut and paste. 7/28/2015 09:48:48.96 <I> telnetd listening on port 23 07/28/2015 09:48:41.66 <DM.NOTICE> DM started 07/28/2015 09:48:41.56 <NM.STRTPROC> The Node Manager (NM) has started processing. 07/28/2015 09:48:40.67 <EPM.START> EPM Started 07/28/2015 09:48:40.66 <EPM.UNEXPCTREBOOTDTECT> Booting after System Failure. 07/28/2015 09:48:40.31 <EPM.WD_WARM_RESET> Changing to watchdog warm reset mode 07/22/2015 06:01:08.66 <NETTOOLS.SNTP.SRVRNAMENOTRSLVED> Host name dist-fr2.crcsd.abc is not DNS resolved yet 07/22/2015 06:01:08.66 <NETTOOLS.SNTP.SRVRNAMENOTRSLVED> Host name dist-fr1.crcsd.abc is not DNS resolved yet 07/22/2015 06:01:02.77 <TECHSUPPORT.CNCTCLCTFAIL> Failed to connect to the collector 12.38.14.200:800 with SSL disabled (VLAN Mgmt does not have an IP address.)
