The RMM3 is a kind of add-on card which offers convenient, remote KVM (keyboard, video, and mouse)
access and control through the LAN or Internet. It captures, digitizes, and compresses videos and transmits
the videos with keyboard and mouse signals to and from a remote computer. You can use the RMM3 to
gain location-independent remote access to respond to critical incidents and to undertake necessary
maintenance. In addition, the RMM3 offers integrated remote power management using intelligent platform
management interface (IPMI). Therefore, working as an integrated solution in your server, the RMM3 provides
an increased level of manageability over the basic server management available to the system board.
The RMM3 option package contains the following items:
• A ThinkServer Remote Management Module 3 option
• A plastic bag containing a slot bracket, a ribbon cable, three screws, and three plastic standoffs
