Module Hot Swap - ADLINK Technology AMC-7000 User Manual

AMC faceplate when software has stopped and it is safe to
remove the AMC module.
If your system does not have hot-swap aware software running,
behavior of the blue LED is indeterminate. In this case, you may
need to manually shut down applications or operating systems run-
ning on the board prior to board removal, even if the blue LED is lit.
Powering down or removing a board before the operating system
or other software running on the board has been properly shut
down may cause corruption of data or file systems.

2.3 Module Hot Swap

This section describes a recommended procedure for installing a
board module in a chassis. The AMC-7000 module has a latching
mechanism. The Latch Mechanism includes the module handle
with an integrated multi-position shaft and micro-switch (see figure
below).
The module handle is held in place by the faceplate, while the
micro-switch is mounted on the module printed circuit board. The
module handle is used to activate the micro-switch, which allows
for Hot Swap switch as well as for extracting the module out of the
connector and the AMC bay.
There are 3 positions of the Module Handle:
1. Pushed all the way in (IN) - When IN the module sends a
signal to the Shelf Manager that the module is not in the
Hot Swap state and the Shelf Manager will communicate
with the MMC. This is the position that the Module Han-
dle should be in during normal operation.
2. Half Way (HW) - When the Module Handle is in the HW
position, the Hot Swap switch is open and the MMC will
send a Hot Swap event to the Shelf manager.
3. Out (OUT) - When the Module Handle is in the OUT
position the latching mechanism is released and the
module can be extracted.
The use of the Module Handle is used in conjunction with the Blue
LED. Please refer to the text below for more detailed instructions
on insertion and extraction.
