9. Serial port connector (10-1 pin COM1)
These connectors are for the serial (COM) ports. Connect the serial port module cable
to the connector, then install the module to a slot opening at the back of the system
chassis.
10. Power Supply SMBus connector (5-pin PSUSMB1)
This connector allows you to connect SMBus (System Management Bus) to the PSU
(power supply unit) to read PSU information. Devices communicate with an SMBus
host and/or other SMBus devices using the SMBus interface.
This connector functions only when you enable the ASUS ASMB10.
Power supply is required to meet PMBus specification and customized BMC FW may be
needed. Please contact ASUS if your need further support.
The COM module is purchased separately.
