C621A WS TPM-SPI Header (13-pin TPM_BIOS_PH1) (see p.1, No. 32) PSU SMBus Header (5-pin PSU_SMB1) (see p.1, No. 2) SPI PIRQ SPI_RST MOSI SPI_CLK X +3.3V SPI_HOLD TPM_CS# GND RSMRST# MISO SPI_CS SPI_WP This connector supports Trusted Platform Module (TPM) system for SPI 1 interface, which can securely store keys, digital certificates, passwords, and data. A TPM system also helps enhance network security, protects digital identities, and ensures platform integrity. ALERT SMBCLK +3V 1 SMBDATA GND PSU SMBus monitors the status of the power supply, fan and system temperature. Intelligent Platform Management Bus Header (4-pin IPMB1) (see p.1, No. 43) Baseboard Management Controller SMBus Header (5-pin BMC_SMB_1) (see p.1, No. 41) IPMB_SDA IPMB_SCL GND No Connect This 4-pin connector is used to provide a cabled base-board or front panel connection for value added features and 3rdparty add-in cards, such as Emergency Management cards, that provide management features using the IPMB. BMC_SMB_PRESENT_1_N Power BMC_SMBCLK7 GND BMC_SMBDATA7 The header is used for the SM BUS devices. CPU HP-SMBus Connector (5-pin CPU1_HSBP1) (see p.1, No. 1) +3V This header is used for the hot CPU_HP_SCL CPU_HP_SDA plug feature of HDDs on the P0_HP_ALERT_L backplane. GND 1 English 31
