RTM‐ATCA‐SXXX Installation

12.4 Use Caution When Installing or Removing RTM

When first installing boards in an empty chassis or onto a carrier card, we recommend that you start at the left of the card cage and work to the right.

When inserting or removing a board in a slot adjacent to other boards, use extra caution to avoid damage to the pins and components located on the primary or secondary sides of the boards.

12.4.1 Preserve EMI Compliance

To preserve compliance with applicable standards and regulations for electromagnetic interference (EMI), during operation all front and rear openings on the chassis or board faceplates must be filled with an appropriate card or covered with a filler panel. If the EMI barrier is open, devices may cause or be susceptible to excessive interference.

12.4.2 Understand Hot Swap

Your RTM is electrically designed for hot swap within a fully powered chassis. To facilitate hot swap, there is a blue LED on the rear 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 rear faceplate when software has stopped and it is safe to remove the advanced rear transition 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.

12.5 Verify Slot Usage

Prevent possible damage to module components by verifying the proper slot usage for your configuration.

12.6 Installing the Advanced Rear Transition Module

This section describes a recommended procedure for installing the RTM module in a chassis.
