Trusted Platform Module Header

This header is used to connect a Trusted Platform Module (TPM), available separately from a third-party vendor. A TPM is a security device that allows encryption and authentica- tion of hard drives, disallowing access if the TPM associated with it is not installed in the system. See the table on the right for pin definitions.

Two Gigabit Ethernet ports (designated LAN1 and LAN2) are located beside the VGA port. Additionally, there is a dedicated LAN port for IPMI on top of the two rear USB ports. These Ethernet ports accept RJ45 type cables.

A RAIDKey header, located at JIBTN1, provides RAID function support in order to use RAID 5 SAS support.
