Chapter 3 REMOTE UNIT OVER IP FEATURES
3-7
NWA-088654-001 Rev.1.0

SYSTEM CONDITIONS
Conditions for License
• The same number of License for Remote Unit license as the number of Remote Units are required
for Remote UNIT over IP system.
• Regardless of Main Unit or Remote Unit, SV9300 consumes the number of ports or licenses in order
of stating up blades, or in order of connecting IP terminals.
• When the number of port and number of license of License data are insufficient, it causes the IP
terminal connection failure.
• After License data is loaded to the Main Unit, the service, number of port, and number of license to
be used by each Remote Unit are sent to the flash memory of each Remote Unit’s CPU blade auto-
matically. When Remote Units operate with survival mode, this data is used.
• Data to be used by each Remote Unit is stored in the flash memory every 10 minutes. When a Remote
Unit starts operating with survival mode within 10 minutes from starting up, the system does not
operate normally because the data is not stored in flash memory. The system should be observed for
more than 10 minutes after starting up.
• The license condition for Remote Unit in survival mode is changed so that the same number of li-
censes as the Main Unit can be used for a definite period of time from survival mode start. By this
change of license condition, all IP terminals which were registered in the Main Unit in the normal
mode can be registered to Remote Unit during the survival mode.
The functional conditions are as follows.
– This function can be provided only by applying SV9300 software.
– The Temporary License Information expires after 15 days operation in Survival mode and is delet-
ed.
The validity of Temporary License Information can be extended up to 60 days by optional license.
The temporary license Information will be also deleted once one week elapses after the CPU power
is turned off.
– By using Fault Kind No. 017(set by CMEA Y=2), expiration of the license data can be notified.
This is registered in the Remote Unit in survival mode at the ten days before the license expires or
when the license expires.
– When the survival mode of Remote Unit starts again after the license expires, the number of
available licenses is limited to the number of IP terminals that have been logging into the Unit in
the normal mode.
– The license data copy from the Main Unit is executed not only at the survival mode start but also
at the system data copy execution.
