TPM Header/Port 80 Connector (TPM Port)
The JTPM1 and JTPM2 headers are used to connect a Trusted Platform Module (TPM), which
is available from a third-party vendor. A TPM is a security device that supports encryption
and authentication in hard drives. It enables the motherboard to deny access if the TPM
associated with the hard drive is not installed in the system.

Expansion Slots
The motherboard includes six expansion slots (Slot1 through Slot6). Slots 1, 3 and 5 are
PCIe 4.0 x4 slots and Slots 2, 4 and 6 are PCIe 4.0 x16 slots.
UID Switch and LED Indicator
A Unit Identifier switch (UID_SW) and a UID LED (UID LED1) are located on the I/O backpanel,
to the right of the VGA port. A front UID LED is also provided on pins 7 & 8 of JF1 (front
control panel header). When you press the UID switch, both rear and front UID LED indicators
will turn on. Press the UID switch again to turn off the LED indicators. Use this UID Indicator
system to allow for easy identification of a systen in a rack.
Note:
UID can also be triggered via IPMI on the motherboard. For more information on IPMI,
please refer to the IPMI User's Guide posted on our website at
