2.5 Use Caution When Installing or Removing RTM
2.5.1 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.
2.5.2 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, the behavior of the blue LED is
not determined. 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.
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.
