The H.110 Basic Rate ISDN Board
3.5 Hot Swapping a Board
The Infinity Series H.110 Basic Rate ISDN Board can be “hot swapped,”
that is it can be removed from a functioning system without turning the
power off or interrupting applications. However, to be able to do this, the
host processor must be equipped with suitable hot swap drivers as well as
a hot swap manager which will alert applications when a board has been
inserted or removed from the system so that resources can be properly
managed. It is beyond the scope of this manual to describe the operation
of either the hot swap driver or hot swap manager.
Each H.110 board is equipped with a switch linked to the lower ejector tab
and a blue LED. This combination is used to coordinate the actions of an
operator with the system software. When inserting a board, the board is
pushed in part of the way until the blue LED is illuminated. The insertion
may then be completed. When the connection process is complete, the
LED will go out. To remove a board, the lower ejector handle is depressed
until it is in the unlatched position. When the blue LED comes on, the
board may be removed from the system.
The rear board
MUST ALWAYS
be inserted
BEFORE
the front board,
and removed
AFTER
the front board.
To install the front board in a system under power:
1.
Insert the board with the ejector tabs spread apart until partially
engaged.
2.
Wait until the blue LED is illuminated.
3.
Finish inserting the board by pushing the ejector tabs towards each
other. The LED should then go out.
