2.2.2 imaging Symphonie Housing Frame

It is not necessary to switch off the power when installing or removing a module from/to Symphonie.
To install a module, follow these steps. For a closer look at card installation and removal, refer to the
housing frame's Guide to Installation and Operation.
Rear Module Installation
Before installing, check the rear panel corresponds to the card to install. If no rear module is present,
follow the procedure below to install it.
In order to maintain the inter-rear module spacing, make sure to remove and replace one rear
module at a time. That is, at all times, there must be at least 15 rear modules installed. To install a
module, follow these steps.
1. Locate an empty compartment.
2. Make sure that the rear panel corresponds to the card to install, the Reference
switch LK1 is used to select the (75 Ω) reference source for the imaging module.
Selecting LOCAL (LK1 position 2-3) drives the reference signal, connected to the
rear module, to the imaging module. However, sliding LK1 to position 1-2,
connects the imaging module to the Symphonie global reference.
3. Carefully place the rear module between the rear module guides (refer to Figure
2.4) and slowly push the module towards the front until it rests against the rear
panel. It may require a light pressure to compress the EMI gaskets on
4. Using a flat edge screwdriver, secure the top and bottom screws to the frame.
