Remote (System) Upgrade - NEC Univerge SV8100 Features And Specifications Manual

UNIVERGE SV8100
Description
With PC Programming, the UNIVERGE SV8100 can be remotely upgraded to a newer version of main
system software. When a new version of main system software is released, a firmware package file is
provided. Using either the WebPro or PCPro application, a technician can remotely upgrade the firmware
on the CD-CP00-AU. The upgrade can be applied immediately, or at a scheduled date and time. Remote
Upgrade is supported only via a LAN connection. A modem or serial connection is NOT supported for
Remote Upgrade.
Conditions
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 2:00PM a
technician schedules an update to happen at 12:00AM. When he/she clicks start (2:00PM),
it begins transferring the file to the USB thumbdrive on the CD-CP00-AU. At this time the
telephone system experiences sluggishness until the file transfer is complete. When the
time turns to 12:00AM, the telephone system resets and switches to the new firmware.
The Package file needed is provided by NEC at the time the new version of main system
software is released.
A USB thumbdrive is required to be connected to the CN5 connector for Remote (System)
Upgrade. During the Firmware Upgrade, the Package file is copied to the CF and extracted.
The system then resets and boots off the compact flash.
Booting from the USB thumbdrive does not replace the firmware in Flash Memory on the
CD-CP00-AU.
Up to two versions of firmware are kept on the USB thumbdrive. One version is the current
version that the CD-CP00-AU 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
CD-CP00-AU can revert back to the old version.
The CD-CP00-AU boots from its Flash Memory if no USB thumbdrive is installed.
The time entered on the Firmware Upgrade screens is relative to the time on the
CD-CP00-AU, not the PC that PCPro or WebPro was launched from. The user should take
into account time zone differences when using this feature.
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 or serial connection is not
supported for Remote Upgrade.
Default Setting
At default, both PCPro and WebPro are set to Update Immediately after the upload.
