PMBus connector, TPM connector, Memory slots

PMBus connector

The BMC can read the power supply status registered through PMBus. You do not need to connect any device to the PMBus connector. This connector is kept for power management in models with redundant power supply modules. The function of the PMBus connector is not available for models with a screw-secured non-hot-swap power supply.

TPM connector

Used to connect a TPM module, which is a security chip, to protect your server and strengthen server security. See “Installing or removing the TPM module” on page 109.

Memory slots

Your server system board provides four memory slots to support up to four memory modules. For more information, see “Memory module installation rules” on page 90.

iButton socket

Your server supports onboard SATA software RAID levels 0, 1, and 10. However, you can activate onboard SATA software RAID 5 by installing a ThinkServer SATA Software RAID 5 activation key in the iButton socket. For more information, see “Installing or removing the ThinkServer SATA Software RAID 5 Key” on page 102.

Main power connector

Used to connect the 24-pin P1 power connector of the power supply to provide main power to your server.

5-pin system fan 2 connector

Used to connect the cable of the upper front system fan (front system fan 2) if your server model has two front system fans.

Microprocessor

A microprocessor incorporates most or all of the functions of a computer's central processing unit (CPU) on a single integrated circuit. The microprocessor for your server is secured in the microprocessor socket on the system board and a heat sink and fan assembly is installed above the microprocessor to provide cooling. For more information about your microprocessor type, see “Features” on page 7.

Intel C202 chip

The Intel C202 chip on the system board serves as a platform controller hub (PCH), which provides the data buffering and interface arbitration required to ensure that system interfaces operate efficiently and provides the bandwidth necessary to enable the system to obtain peak performance. The chip supports and provides many features, including the onboard SATA software RAID.

4-pin system fan 1 connector

Used to connect the cable of the lower front system fan (front system fan 1).

–

SATA connectors

Used to connect SATA signal cables for the SATA hard disk drives or SATA optical drives.
