3.1.10 J18 (Ejector Switch)
The ejector handles are used when cPB-4612 is inserted or removed (hot swapped) from a chassis that is
powered on. When a customer wishes to remove a board from a system that is powered on then the
ejector handles should be opened just enough to disengage the handles from the chassis, but without
fully disengaging the J-connectors from the back of the chassis. This will trigger a shutdown of the
operating system and then the BMC will power off the board and light the blue hot swap LED on the front
panel. Once the blue LED on the front of the board is lit, then it is safe to remove the board from the
chassis.
Note
: In order for the shutdown sequence of the OS to take place a hot swap driver must be
installed into the OS. See the cPB-4612 support page for this driver or procure the cPB-4612
hot swap kit.
The J18 (ejector handles) need to be closed in order for the board to boot up.
