5.6 Expansion of modular cabinet system
Expanding the modular cabinet system means that a new cabinet has to be interconnected to an
existing cabinet. Modular cabinets are interconnected in a fixed sequence. The correct cabinet
sequence and all other details can be found in section ‘Installation instructions’ in this manual.
A special interconnection set is available to connect the cabinets. This set can only be mounted when
a number of boards are removed at the side where the interconnection is to be made. Therefore,
before starting, make a printout of the relevant CSM window of the current system to know the current
board positions and ensure that all cables are marked properly. Thus you can make sure that the
current cabinet can be re-installed as it was. Ensure that you have an up-to-date back-up of the CPU
data (EEPROM upload) as well.
Because a number of boards have to be removed from the current system, ensure that you have
proper ESD safe boxes to put the boards in.
Note:
The easiest way to install a modular cabinet’s cabling, is to put the cabinet on its back on a desk.
Procedure
1. Make a list of all board positions using CSM.
2. Make a system backup with the menu File-System Backup.
3. Switch off the power of all cabinets, disconnect battery and mains.
4. Remove the front cover of the cabinet where the new cabinet must be connected.
5. For the 3 right most slots, disconnect the cabling and remove the boards (left most slots if the
new cabinet comes at the left side).
6. Remove the conducting tape or break-out plate from the side panel adjacent to the new cabinet.
7. Place the shielding gaskets from interconnection set in the created hole with its springs outside,
see ‘Installation instructions’.
8. Feed the flat cable through the hole and connect to backplane connector.
9. On the new cabinet, at the correct side, remove the conducting tape or break-out plate and fit the
shielding gaskets.
10. Wall-mount the new cabinet. Keep a distance of 8 mm to the adjacent cabinet. While hanging the
new cabinet feed the flat cable through the side panel hole.
11. Secure the new cabinet to the wall by the retaining screws.
12. From both cabinets, at adjacent sides, remove the R-networks from the backplane.
13. Interconnect the ground strips of both cabinets using the protective ground cable.
14. Re-install the boards and cabling of the ‘old’ cabinet.
15. Install the new cabinet according to the ‘Installation instructions’ in this manual.
16. Correct the number of cabinets in the system with System-Configuration.
