6.4 Exchanging a modem card
The modem cards can be replaced during operation. The Rosemount 2460 System Hub supports
plug-and-play and the proper protocol settings will automatically be used when the Rosemount 2460
detects a new modem card.
1. Loosen the captive locking screws and open the lid.
2. Turn the locking screw 90 degrees and open the modem card cover.
3. Carefully pull the modem card out.
4. Insert the new card into the card holder. Gently push the modem card until it is properly plugged in to
the Main board contact.
5. Close the modem card cover.
6. Turn the Locking screw to secure the cover.
