LED Description
OOS Out Of Service
This LED is multicolored (red/amber) and is programmable through IPMC.
Its default color is red and its local control state (on or off) reflects the payload
power state (on or off).
It permits override control by higher layer software, such as middle ware or
applications, as specified in PICMG 3.0 specification.
IS Payload Power Status
This LED is multicolored (green/red/amber) and is programmable through
IPMC.
Its default color is green and its local control state is off.
It permits override control by higher layer software, such as middle ware or
applications, as specified in PICMG 3.0 specification.
ATN Attention
This LED has amber color and is programmable through IPMC.
