2.4.2 Understand Hot Swap
Your AMC-S402 is electrically designed for hot swap within a fully powered chassis.
To facilitate hot swap, there is a blue LED on the front faceplate. This LED is under
software control.
If your system is using software that provides full hot swap capabilities, the software
will illuminate the blue hot swap LED on the 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 running 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.
2.5 Verify Slot Usage
Prevent possible damage to module components by verifying the proper
slot usage for your configuration.
In most cases, electronic keying (E-keying) will prevent power on of a board into an
incompatible slot. However, as an extra precaution, you should be familiar with the
slot purpose.

This section describes a recommended procedure for installing a board module in
chassis. The AMC-S402 module has a latching mechanism. The latch mechanism
includes
switch.
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
the module out of the connector and the AM
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
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 mana
3. Out (OUT) - When the Module Handle is in the OUT positio
mechanism is released and the module can be extracted.
