Conditions
[Both With MEMDB/Without MEMDB:]
• When doing a Firmware Upgrade, the telephone system can become sluggish during the file
transfer portion of the update. You should perform updates after hours, even if the update is
scheduled. The file transfer happens when the update is set. For example, at 2:00 PM a technician
schedules an update to happen at 12:00 AM. When he/she clicks start (2:00 PM), it begins
transferring the file to the MEMDB or Flash Memory thumbdrive on the CPU Unit. At this time the
telephone system experiences sluggishness until the file transfer is complete. When the time turns
to 12:00 AM, the telephone system resets and switches to the new firmware regardless of extension
or trunk busy status.
• File extension (*.pkg) have to use MEMDB installed system and can not upload to Non MEMDB
system. File extension (*.nomem) have to use Non MEMDB system and can not upload to MEMDB
system.
• Individual software or firmware can not use for Remote Upload.
• The Package file needed is provided by NEC at the time the new version of main system software is
released.
• The time to upload a firmware package file is directly related to the file size. Generally, it takes a few
minutes.
• Remote Upgrade is supported only via LAN connection. A modem connection is not supported for
Remote Upgrade.
[With MEMDB:]
• MEMDB thumbdrive is required to be connected to the CPU Unit for Remote (System) Upgrade.
During the Firmware Upgrade, the Package file is copied to the MEMDB and extracted. The system
then resets and boots up.
• Up to two versions of firmware are kept on the MEMDB thumbdrive. One version is the current
version that the CPU Unit used to boot up from. The other version is the new version that is used on
the next boot up. If the boot up fails when switching to the new version, the CPU Unit can revert
back to the old version.
• The CPU Unit boots from its Flash Memory if no MEMDB thumbdrive is installed.
