AMC-S402 Installation

2.4.2Understand 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.

2.5Verify 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.

2.6Module Hot-Swap

This section describes a recommended procedure for installing a board module in a chassis. The AMC-S402 module has a latching mechanism. The latch mechanism includes the module handle with an integrated multi-position shaft and micro- 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 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 handle 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.
