Indicators for hot-plug PCI slots
The indicators ((b) and (c) on figure 39 on page 95) are located on the card
guide on the inside of the server.
The indicators on these slots behave differently depending on whether (table 3)
or not the operating system supports hot-plug functionality (table 4 on page 63):

Device operating: a problem has occurred.
There are two possible causes for this status:
–
The MRL sensor was pressed without
authorization. This status cannot be exited
(NMI initiated: see section “Hot-Plug PCI
Error Indicator Lighting” on page 76).
–
There was a power failure during the
enable sequence (the PCI slot is reset to
disable status).
