7.1.1.2 Board Battery Maintenance
It is recommended that the batteries in the PowerCPU boards should be replaced by batteries
of the same type every two years. Dead batteries must be disposed of according to the battery
manufacturer's instructions.
7.1.1.3 Maintenance of Ventilation System
At the same time as replacing the batteries, clean the system ventilation holes using a brush or
a lint-free cloth.
When a fan fails, only the T0/T2 external digital accesses and the first two interfaces of the
digital stations remain operational.
7.1.1.4 Replacing the PowerCPU Board
It is necessary to adapt the software key after replacing the PowerCPU board.
1. The new PowerCPU board has no software key:
• You know the new software key corresponding to the new PowerCPU:
•
•
•
•
• You do not know the new key corresponding to the new PowerCPU: use the old key
until you can enter the new one (you have 30 days). The remaining actions are
identical to those shown in the previous section
2. The new PowerCPU software key corresponds to the serial number:
• The new key offers the desired level of service:
•
•
• The new key does not offer the desired level of service: change the key
3. The new PowerCPU board software key does not match the serial number:
One is in the same situation as case 1, except that the system boots with the level of
service offered by the key on the PowerCPU, with temporary validity.
7.1.1.5 Adding and Replacing Interface Boards
This section describes how to add an interface board into a vacant slot in the system and how
to replace an existing board with a new one.
Note:
Always take anti-static precautions when handling boards. Before coming into direct physical
contact with a board, make sure you touch a grounded metal surface to remove static charge
