2.4Installing and Removing the RTM

The RTM can be installed into a powered or non-powered system.

RTM Damage

Installing the RTM with other blades than the ATCA-F120 may damage the RTM and the front blade.

Only install the RTM with the Emerson ATCA-F120 blade.

Damage of Circuits

Electrostatic discharge and incorrect RTM installation and removal can damage circuits or shorten their life.

Before touching the RTM or electronic components, make sure that you are working in an ESD-safe environment.

2.4.1Installing the RTM

You can install the RTM into a system if the front blade is already installed or if it is not installed.

If the front blade is already installed, its payload has to be powered down first.

Installation Procedure with Installed Front Blade

The following procedure describes the installation of the RTM. It assumes that your system is powered. If your system is unpowered, you can disregard the blue LED and thus skip the respective step. In this case it is a purely mechanical installation.

1.Locate the slot the RTM is to be installed into the shelf's rear which must be the same as that of the front blade.

2.Open the lower handle of the front blade in order to power down its payload. The blue LED on the front blade starts to flash. This indicates that the front blade is informing the shelf manager about its desire to power down its payload.

3.Wait until the blue LED on the front blade is ON.

This indicates that the front blade’s payload is powered down.
