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.

A jumper is a short length of conductor used to set up or adjust a printed circuit board, such as the system board of a computer. A jumper usually is encased in a non-conductive block of plastic for convenient use
