Operation and Maintenance
3. Remove the defective interface card by pressing the two lateral metal clamps outward at the same time
and gently lifting the interface card.
4. Place the new interface card at a slight angle into the required slot (see Fitting an interface card). Make
sure the angled side of the interface card is facing backwards (i.e. it must not project over the wiring
adapter slots).
5. Carefully press the interface card downwards until the two lateral metal clamps engage.
6. Fit the housing cover.
7. Reconnect the system to the power supply.
6.3.3.2 New card with fewer ports
A card is replaced by a similar card with fewer ports.
Procedure:
Change the card and put the system into operation again. Similar procedure as described in Replacing a
defective interface card.
The following data is deleted:
• The system and terminal configuration data of the terminals on the interfaces that are no longer present
in the new configuration.
• The system configuration data of the network interfaces that are no longer present in the new
configuration.
Table 80: Example: Reducing the number of terminal or network interfaces
TIC-4TS → TIC-2TS The configuration data of terminal interfaces 3 and
4 are deleted.
TIC-4AB → TIC-2AB The configuration data of network interfaces 3 and
4 are deleted.
Note:
If the terminal configuration data of system terminals is deleted following the reconfiguration of a
card, a warning message will appear beforehand to give you the possibility of cancelling the process.
However, this is possible only if the configuration data of the original card was not already deleted
beforehand.
6.3.3.3 New card with more ports
