Description
Physical Slot Number (PSN): Indicates the physical slot number
attached to this Port.
Reserved
Electromechanical Interlock Present (EIP): When set to 1b, this
bit indicates that an Electromechanical Interlock is implemented on
the chassis for this slot.
Slot Power Limit Scale (SPLS): Specifies the scale used for the
Slot Power Limit Value.
00 = 1.0x
01 = 0.1x
10 = 0.01x
11 = 0.001x
If this field is written, the link sends a Set_Slot_Power_Limit
message.
Slot Power Limit Value (SPLV): In combination with the Slot Power
Limit Scale value, specifies the upper limit on power supplied by slot.
Power limit (in Watts) is calculated by multiplying the value in this
field by the value in the Slot Power Limit Scale field.
If this field is written, the link sends a Set_Slot_Power_Limit
message.
Reserved
Power Indicator Present (PIP): When set to 1b, this bit indicates
that a Power Indicator is electrically controlled by the chassis for this
slot.
Attention Indicator Present (AIP): When set to 1b, this bit
indicates that an Attention Indicator is electrically controlled by the
chassis.
MRL Sensor Present (MSP): When set to 1b, this bit indicates that
an MRL Sensor is implemented on the chassis for this slot.
Power Controller Present (PCP): When set to 1b, this bit indicates
that a software programmable Power Controller is implemented for
this slot/adapter (depending on form factor).
Attention Button Present (ABP): When set to 1b, this bit indicates
that an Attention Button for this slot is electrically controlled by the
chassis.
