13.2 Replacing a Voice Card
To replace a voice card while the Access Bank II - SNMP is hot, refer to Figure 13-1, then follow
these steps:
1. Release the two thumb screws on the back plate of the Access Bank II - SNMP and remove
the plate.
2. On the voice card you wish to remove, lift the card ejector latches to release the card from its
internal connector.
3. Carefully slide the card out of the back of the Access Bank II - SNMP.
4. Check the channel attenuation loss and gain option settings on the replacement voice card
and verify they are set correctly for your intended application. If necessary, reset the channel
attenuation option settings.
5. Ensure that the replacement voice card is positioned correctly in the guide rails, then care-
fully slide the card into the slot.
6. Press the card ejector latches in towards the card until the 64-pin DIN connector on the card
mates with a matching connector on the Controller card.
7. Replace the back plate and tighten the thumbscrews.
Caution: “Hot swapping” an FXS card will cause all 24 channels to go
through Trunk Processing for 16 seconds. All calls will be disconnected and
must be dialed again after the Access Bank II - SNMP returns to its normal
operating state.
