from your body. When holding a board, always wear a grounding device such as a grounded wrist
strap, and do not touch board components that are sensitive to static charge.
Before attempting board installation/exchange, note the following system rules concerning the
detection of boards:
- A detected board is considered to be PRESENT
- A PRESENT board can be ACCEPTED or REFUSED, depending on the system
dimensioning criteria
- On a cold reset, all PRESENT boards are taken into account (irrespective of whether they
are ACCEPTED or REFUSED)
- A board which is PRESENT on a cold reset can later be determined as ABSENT on a
warm reset if in the meantime the board has been unplugged or there has been a board
detection failure
- After a cold or warm reset, new boards are always taken into account and declared as
PRESENT (and then ACCEPTED or REFUSED)
The following table describes situations more specifically relevant to plugging/unplugging
boards.
Situation Description
A board is plugged into a slot never before
occupied
The board is detected as PRESENT and then
determined to be ACCEPTED or REFUSED
(according to configuration criteria, such as au-
thorized positions and maximum hardware capa-
city). If the board is accepted, its accesses are
taken into account depending on the system di-
mensioning criteria.
A board is replaced with another board of
the same type
A board is replaced with another board of a
different type
As above, except when the replacement board is
plugged in, configuration data for the previous
board is cleared.
A PRESENT and ACCEPTED board is un-
plugged
The board's disappearance is detected and the
board is considered as out of order and then AB-
SENT. However, configuration data associated
with the unplugged board remains available.
A PRESENT and REFUSED board is un-
plugged
The board's disappearance is detected and the
board is considered as ABSENT. However, con-
figuration data associated with the unplugged
board remains available.
