Selector replacement

All configuration data of a socket selector is stored in the Rapid Back Up (RBU) memory, which has the same form factor as a SD card. If a selector is broken or malfunctions, a quick replacement is as follows:

Unpack a new replacement unit.
Remove power and connections from the broken unit.
Remove the broken unit.
Open the service port cover. Use a 2 mm allen key.
To remove the RBU, press it inwards and then release the pressure. A spring will push it far enough out so it can be removed.
Remove the socket holders from the broken unit and place them in the same positions on the new unit.
If necessary remove mounting brackets from the broken unit and install them on the new unit.
Move the stickers from the broken unit to the new unit, or create new stickers.
Place the RBU into the card holder of the replacement unit. It can only be inserted in one correct way. Press it firmly to the bottom. A small clicking sound confirms that the spring is locked and the card is secured in the slot.
Close the service port cover and secure it with the screw.
Install the new unit and secure it in its dedicated place.
Reconnect all connections to their initial places and connect power to the new unit.

Detailed instructions and figures showing the installation of the selector, cables and socket holders are given in the Installation chapter.
