/SYS/INTSW Physical security This sensor tracks the state of the
chassis intrusion switch. If the server’s
top cover is opened while the AC power
cords are still connected so that power
is being applied to the server, this
sensor asserts. If the top cover is
subsequently replaced, this sensor is de-
asserted.
For more information, see
“Server
Chassis Intrusion Sensors” on page 17 .
/SYS/SP/SP_NEEDS_REBOOT Physical security This sensor asserts when the server’s
cover is removed while the AC power
cords are still connected so that power
is being applied to the server. However,
this sensor is not cleared by merely
replacing the cover.
This sensor indicates a server fault that
must be cleared; otherwise, the SP will
operate in a degraded mode.
To clear this fault, replace the server’s
top cover, power down the server’s
host, and reboot the server’s SP.
