PPC/CPCI-690
The board provides the following elements as man-machine interface:
• Hot-swap switch
Integrated in the lower handle of the front panel, it allows the user to
indicate the intention to remove the board to the system controller.
• Blue hot-swap LED
If ON, it indicates that you are allowed to remove the board.
For information on board status concerning the hot-swap conditions, the
board provides ENUM# and HEALTHY# signals for hot-swap-controller
(HSC) notification and SENTINEL's Control and Status registers.
After installing the board into or before removing it from a powered sys-
tem, the interrupt ENUM# signal is generated and passed to the system
board of the CompactPCI system to indicate a service request. The Control
and Status registers allow to determine the source of the ENUM# signal
and to control the hot-swap LED. The HEALTHY# signal is active whenev-
er all backplane and on-board voltages are within their operating range.
• Board damage and data loss
Installing the board under hot-swap conditions in system slots causes
board damage and data loss.
Therefore, only install the board under hot-swap conditions if the
board is to be operated in slots for which hot swap is explicitly per-
mitted by the system documentation (in most hot-swap systems
peripheral slots only).
• Board damage
Touching the board or electronic components in a non-ESD protected
environment causes component and board damage.
Before touching boards or electronic components, make sure that you
are working in an ESD-safe environment.
The installation procedure depends upon the system the board is to be in-
stalled in.
