UART interface.
DHCP
In addition to support static IP, the BMC support DHCP, DNS and dynamic update in DNS
(DDNS). When DHCP lease fails, BMC will use 192.168.0.120 as the default IP.
Time Sync
In BMC design, BMC does not have a local RTC to know what time it is. Each time BMC will
get the current time from system PCH after BMC boot. The current time is updated period-
ically from the PCH. The remote console program interpret this time as pre-initial.
SEL
BMC supports IPMI 1.5/2.0 standard SEL operation. It can keep SEL log. Event happened in
BIOS side will be logged by using Add SEL Entry command. BMC will store them in FLASH,

but will go through PEF as usual. If AC powers off, all SELs will remain in NV.
