Failure to run the FRUSDR Update Utility may cause the platform management sub-system to report false errors causing your platform to operate erratically.

Note: It is highly recommended that you update your Server Board SE7520JR2 with the latest system software, including the FRUSDR Update Utility. These can be downloaded from the following Intel web site: http://support.intel.com/support/motherboards/server/se7520jr2/

9.3Clearing CMOS

Depending on which System Management level is used on the server, there are three possible methods that can be used to clear the system CMOS:

•System Configuration Jumper Block J1H2 (A) - CMOS Clear Jumper - Supported with all management levels

•Control Panel CMOS clear sequence (IMM Professional and Advanced system only)

•CMOS Clear state asserted via BMC CMOS Clear Options command (allows remote clear operation) (Professional and Advanced systems Only)

9.3.1CMOS Clear Using J1H2 Jumper Block

All three management levels support clearing the CMOS using by moving the CMOS Clear jumper of the System Config jumper block (J1H2- A) from the default position pins 1-2 to pin position 2-3. This method requires the following procedure to be followed:

1.The power be removed from the system

2.The J1H2 jumper is moved

3.The system is rebooted.

4.BIOS Setup options are saved

5.System is powered down and AC is removed

6.Jumper J1H2 is moved back to default position

7.AC is restored

8.System is rebooted.

9.3.2CMOS Clear using Control Panel

In systems configured with an Intel Management Module, Professional or Advanced, CMOS can be cleared using buttons on the system Control Panel that will both assert the BMC CMOS
