3.1.1 P4 Cross-Connect Control

This jumper is used to control ShMC cross connect. ShMC cross connect is the ability to connect to two ShMCs at 10/100 each rather than use a single 10/100/1000 for a single ShMC. The first ShMC port is number 1 on the Base. The second ShMC port is number 17 on the Base.


TABLE 3-2 P4 Cross-Connect Jumper Settings

P4

Default

Function

OFF

 

Software control of cross connect.

1-2

Default

Force cross connect enabled, base channel 1 is two 10/100BaseTX ports.

3-4

 

No cross connect; base channel 1 is 10/100/1000Base-T.


3.1.2 P6(1-2) Fabric Zero Reset Configuration Word

This jumper is used to configure the Fabric Gigabyte CPU to use the default Reset Configuration Word, or use the one in the flash.


TABLE 3-3 P6 (1-2) Fabric Zero Reset Jumper Settings

P6(1-2)

Default

Function

ON

 

Use default Reset Configuration Word (all zeros)

OFF

Default

Use Reset Configuration Word in flash


3.1.3 P6(3-4) Base Zero Reset Configuration Word

This jumper is used to configure the Base CPU to use the default Reset Configuration Word, or use the one in the flash.


TABLE 3-4 P6 (3-4) Base Zero Reset Jumper Settings

P6(3-4)

Default

Function

ON

 

Use default Reset Configuration Word (all zeros)

OFF

Default

Use Reset Configuration Word in flash


3.1.4 P8(1-2) Base Write Protect

This jumper configures write protection on the Base reset configuration word.


TABLE 3-5 P8 (1-2) Base Write-Protect Jumper Settings

P8(1-2)

Default

Function

ON

 

Disable the write protection of the Base reset configuration word

OFF

Default

Write protect the Base reset configuration word


3.1.5 P8(3-4) Fabric Write Protect

This jumper configures write protection on the Fabric reset configuration word.


TABLE 3-6 P8 (3-4) Fabric Write Protect Jumper Settings

P8(3-4)

Default

Function

ON

 

Disable the write protection of the Fabric reset configuration word

OFF

Default

Write protect the Fabric reset configuration word


3.1.6 P9 IPMC Firmware Program

These jumpers configure IPMC firmware write actions via the debug serial port.


TABLE 3-7 P9 IPMC Firmware Program Jumper Settings

P4

Default

Function

OFF

Default

Normal operation

1-2

 

Install to program IPMC firmware via the debug serial port

3-4

 

Install to program IPMC firmware via the debug serial port


3.1.7 P10(1-2) IPMC Reset

This jumper configures the IPMI subsystem reset function.


TABLE 3-8 P10 (1-2) IPMC Reset Jumper Settings

P10
(1-2)

Default

Function

ON

 

Disable IPMI subsystem (hold it in reset)

OFF

Default

Enable IPMI subsystem


3.1.8 P10(3-4) IPMC FWE

These are reserved and should be left configured for the default setting.


TABLE 3-9 P10 (3-4) IPMC FWE Reserved Jumper Settings

P10
(3-4)

Default

Function

ON

 

 

OFF

Default

Normal operation


3.1.9 P11(1-2) Forced-Board Enable

This jumper controls whether the switch is forced on when it is powered up, or if the IPMI subsystem controls the power up of the switch. Forcing power to the board is not enough for the board to boot. The board could still be held in reset. Configre P11 (3-4) jumper setting as well to bring the board out of reset.


TABLE 3-10 P11 (1-2) Forced-Board Enable Jumper Settings

P11
(1-2)

Default

Function

ON

 

Force power on. Use this to run without a ShMC.

OFF

Default

IPMI controls power to the board.


3.1.10 P11(3-4) IPMC Board Reset

This jumper configres the IPMI to send a reset signal that will reset the entire board


TABLE 3-11 P11 (3-4) IPMC Board Reset Jumper Settings

P11
(3-4)

Default

Function

ON

 

IPMI subsystem cannot reset the switch. Use this to run without a ShMC.

OFF

Default

IPMI subsystem can reset the switch and hold it in reset.


3.1.11 P12(1-2) and P12 (3-4) EMI Ground to Logic Ground

The switch and the entire AdvancedTCA shelf separate the ground of the chassis itself from digital ground for EMI protection. This jumper configures the two grounds.


TABLE 3-12 P12 (1-2) and P12 (3-4) Grounding Jumper Settings

P12
(1-2)
(3-4)

Default

Function

OFF

Default

Separate EMI ground and logic ground.

1-2

 

Connect EMI ground to logic ground.

3-4

 

Connect EMI ground to logic ground.


3.1.12 P13 Serial Direction

The front panel serial port and the RTM serial port are mutually exclusive; only one can be used at a time. The serial port can be forced to the front or the RTM, or it can be controlled by the software.


TABLE 3-13 P13 Serial Direction Jumper Settings

P13

Default

Function

OFF

Default

Software control of serial direction.

1-2

 

Front serial port active; RTM serial port disabled.

3-4
