TN750 and TN750B
You need to back up a TN750 or TN750B in the following situations:
Before someone removes a TN750 or TN750B from the switch
Before someone shuts down power to the switch.
In both situations, the system loses any announcements stored on the circuit pack.
Therefore, you need to backup announcements stored on the TN750 or TN750B circuit
packs to the Mass Storage System (MSS). When someone inserts or resets a circuit pack,
or when someone powers up the system, the switch checks the circuit pack for
announcements. If the system determines that there are no announcements on the circuit
pack, then it automatically restores the announcements from the MSS. Only one TN750
can be stored in MSS.
!
CAUTION:
TN2501AP and TN750C
The TN750C circuit pack has on-board FLASH memory backup, which substantially
reduces the time required for power-up restore and eliminates the need for a manual save
of the circuit pack contents.
The system retains announcements on the circuit packs, even when someone removes the
circuit pack or when the system loses power. Therefore, the TN2501AP and the TN750C
do not require the save and restore procedure. However, you can still use the save and
restore procedure to copy the contents of a TN750C to another circuit pack.
Note:
Note:
Multiple integrated announcement circuit packs
Multiple integrated announcement circuit packs can be installed in Avaya switch platforms.
However, only one of these circuit packs can be a TN750 or a TN750B. Any additional
circuit packs must be TN2501AP or TN750C circuit packs.
!
CAUTION:
Integrated announcements and announcements recorded on external devices
CAUTION:
The announcements from MSS that are automatically restored are the last
announcement saved to MSS. If multiple circuit packs are used, MSS might
not contain the announcement for the B or A circuit pack.
The contents of the TN2501AP cannot be saved to the MSS. To copy the
contents of the TN2501AP, use FTP to transfer the information to a
computer for storage.
CAUTION:
Do not copy announcements from a TN750C to a TN750 or TN750B. This
action may corrupt the announcement data.
