Hot Swap
The PICMG 2.1 Hot Swap compliant CR! I allows the orderly insertion and
extraction wider power, without adversely affecting system operation.
According to the PICMG 2.1 Hot Swap specification, the CR! I uses its 2. 7 k.Q
pull-up resistors for biasing purposes during hot insert. During th
i
s
phase all
CPCI signals are pre-c
h
arged to I

The Hot Swap process can be described in terms of three processes
:
Physical Connection Process - describes the acts of:
•
Hot Insertion
-
by which
CR!
I is installed in a live system
(
as a non
system CPU)
•
Hot Extraction - which means the CR! I is removed from a live system (as
a non-system CPU)
•
Hardware Connection Process - Power Up/Down of the CR! I onboard
voltages
•
Software Cowiection Proc.ess - Cow1ection/discow1ection of the software
layer(s)
At the end of the Physical Cowiection Process (the shortest Pin has cow
i
ec
.t
io
n
)
the Hot Swap controller powers up the onboard voltages in a defined mamier.
After the handle switches are closed, the CPCI bridge generates an insertion
event, which signals a Hot Swap insertion to the sy
s
tem
.
The system then scans
the CPCI-bus for c
h
anges
.
Please note, that the CPCI baclq,lane must support this function and appropriate
software must be installed for Hot Swap to work properl
y.
