Basic Battery Installation and Replacement
This model of the Telephony Gateway has the ability to provide continued telephone
service during power outages. The battery backup is not intended to take the place
of AC power.
Use this procedure to install and to replace the backup battery.
1
Press down and pull back on the latch holding the battery door (on the bot-
tom of the Telephony Gateway). Pull the door toward you. Set the door aside
in a safe place.
CAUTION
Risk of equipment damage
Improperly inserting the battery may damage the battery connector in
the Telephony Gateway. Carefully follow the instructions in the next
step to avoid damage.
2
Hold the battery pack so that the guides on the battery align with the slots
on the Telephony Gateway and slide the battery into the bay. The diagram
on the left shows the proper orientation.
Note
: Batteries will not insert completely into the Telephony Gateway if not
oriented correctly. The battery should slide into the bay without significant
force. Line up the guides on the battery with the slots in the battery bay.
