System Board Jumpers And Switches - Lenovo ThinkServer RD630 Hardware Maintenance Manual

13 ThinkServer Management Module
With the integrated ThinkServer Management Module (also known as the BMC chip), no matter what
condition the server operating system is in and no matter if the server is on or off, as long as the server
is connected to network and an ac power source, the interaction with the TMM controlled servers can be
achieved through system network. The user can obtain the server hardware health information and SEL,
and is able to conduct the operations including turning on or off the server, restarting the server, locking
the power switch on the front panel and so on. This part of the server management is independent of the
operating system and is called out-of-band management.
