RW_O
0x0
power_indicator_present:
This bit indicates that a Power Indicator is implemented for this slot and is 
electrically controlled by the chassis.
0: indicates that a Power Indicator that is electrically controlled by the 
chassis is not present
1: indicates that Power Indicator that is electrically controlled by the chassis 
is present
BIOS programs this field with a 1 for CEM/Express Module FFs, if the slot is 
hotplug capable.
3:3
RW_O
0x0
attention_indicator_present:
This bit indicates that an Attention Indicator is implemented for this slot and 
is electrically controlled by the chassis
0: indicates that an Attention Indicator that is electrically controlled by the 
chassis is not present
1: indicates that an Attention Indicator that is electrically controlled by the 
chassis is present
BIOS programs this field with a 1 for CEM/Express Module FFs, if the slot is 
hotplug capable.
2:2
RW_O
0x0
mrl_sensor_present:
This bit indicates that an MRL Sensor is implemented on the chassis for this 
slot.
0: indicates that an MRL Sensor is not present
1: indicates that an MRL Sensor is present
BIOS programs this field with a 0 for Express Module FF always. If CEM slot 
is hotplug capable, BIOS programs this field with either 0 or 1 depending on 
system design.
1:1
RW_O
0x0
power_controller_present:
This bit indicates that a software controllable power controller is 
implemented on the chassis for this slot.
0: indicates that a software controllable power controller is not present
1: indicates that a software controllable power controller is present
BIOS programs this field with a 1 for CEM/Express Module FFs, if the slot is 
hotplug capable.
0:0
RW_O
0x0
attention_button_present:
This bit indicates that the Attention Button event signal is routed (from slot 
or on-board in the chassis) to the IIO’s hotplug controller.
0: indicates that an Attention Button signal is routed to IIO
1: indicates that an Attention Button is not routed to IIO
BIOS programs this field with a 1 for CEM/Express Module FFs, if the slot is 
hotplug capable.
