To correctly reset the date and time before replacing a battery, you must revent the host from automatically powering on and disable any NTP connections.
-> show /SP/policy HOST_AUTO_POWER_ON Properties: HOST_AUTO_POWER_ON = enabled
-> set /SP/policy HOST_AUTO_POWER_ON=disabled
-> show /SP/clock usentpserver Properties: usentpserver = enabled
-> set /SP/clock usentpserver=disabled
Replacing the battery is a cold-service procedure. The server must be completely powered off and power cables disconnected before performing this procedure.
Gently push the battery toward the memory risers to release it from the retention clip.
Press the new battery into the battery holder with the positive side (+) facing away from the metal tab that holds it in place.
The following example sets the date to August 22, 2016, and the timezone to EDT.
-> set /SP/clock datetime=081221302016timezone=EDT Set 'datetime' to '081221302016' set 'timezone' to 'EDT' -> show -d properties /SP/clock Properties datetime = Mon Aug 22 13:20:16 2016 timezone = EDT (EST5EDT) uptime = 2 days 19:56:49 usentpserver = disabled
-> set /SP/policy HOST_POWER_ON=enabled
-> set /SP/clock usentpserver=enabled
-> show /SYS/MB/BAT
