Unit Identifier Switch/UID LED Indicator
A Unit Identifier (UID) switch and a rear UID LED (UID-LED) are located on the I/O back panel.
A front UID switch is located on pins 7 & 8 of the front panel control (JF1). When you press
the front or the rear UID switch, both front and rear UID LEDs will be turned on. Press the
UID switch again to turn off the LED indicators. The UID indicators provide easy identification
of a system that may be in need of service. (Note: UID can also be triggered via IPMI on
the motherboard. For more information, please refer to the IPMI User's Guide posted on our
website at http://www.supermicro.com.)

4.4 Headers

Onboard Fan Header
Five 4-pin fan headers (FAN1~5) are located on the motherboard to provide CPU/system
cooling. These fan headers support both 3-pin fans and 4-pin fans; however, onboard fan
speed control is available only when all 4-pin fans are used in the motherboard. Fan speed
control is supported by a thermal management setting in the BMC (Baseboard Management
Controller). See the table below for pin definitions.
NVMe Connectors
Use the NVMe connectors (P1_NVMe0/P1_NVMe1/P1_NVMe2/P1_NVMe3) to attach high-
speed PCI-E storage devices (supported by CPU1).
