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. 

Before you install your module, please read all cautions, warnings, and instructions 
presented in this section.
