CHAPTER 6 OPERATION AND MAINTENANCE
Replacing a defective interface card
A card is replaced by the same card type with the same number of ports.
Procedure:
CAUTION: Be sure to observe the Safety regulations.
1. Carry out preparations (see Preparations).
2. Remove the housing cover.
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.
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.
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.
Table 6.1: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.
