Remote (System) Upgrade - NEC SL1000 Features And Specifications Manual

SL1000
Description
With PC Programming, the SL1000 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 PCPro application, a technician can remotely upgrade the firmware on the CPU Unit.
The upgrade can be applied immediately, or at a scheduled date and time. Remote Upgrade is
supported only via a LAN connection.

• 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 up-
date to happen at 12:00AM. When he/she clicks start (2:00PM), it begins transferring the file to the
MEMDB thumbdrive on the CPU Unit. At this time the telephone system experiences sluggishness
until the file transfer is complete. When the time turns to 12:00AM, 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.
• MEMDB thumbdrive is required to be connected to the CPU Unit for Remote (System) Upgrade. Dur-
ing 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 ver-
sion 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.
• 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.
Default Settings
At default, both PCPro and WebPro are set to Update Immediately after the upload.
