M3900 firmware download process
The M3902, M3903, M3904, and M3905 sets can be upgraded to the
latest firmware available. The Expec in the EIPE does the firmware
upgrade process. The Nortel Networks Optivity Telephony Manager for
Meridian SL-100, 2.0 (OTM-MSL) server coordinates and logs this
process. The OTM-MSL client controls what the server does.
Only one type of set (that is, M3902, M3903, M3904, or M3905) per
Expec can be upgraded at any one time. Since OTM-MSL can
communicate with multiple Expecs at the same time, this allows
multiple sets throughout the Meridian SL-100 system to be upgraded at
the same time. Multiple download sessions can be scheduled to allow
for different types of sets to be upgraded.
The download process is as follows:
1. New firmware is placed on the Meridian SL-100 SLM drive.
2. A group (must be same set type, that is, all M3903s) of sets on an
Expec are selected.
3. The OTM-MSL server telnets into the Expec.
4. The Expec FTPs into the Meridian SL-100.
5. The firmware is copied to the Expec’s RAM.
6. The sets in the group are individually checked for “idle state”, before
the download starts.
TIP: If a set has any buttons pressed or is off hook, the process
aborts and the system checks the next set for “idle state”.
7. The Expec erases the current Firmware from the set.
Note: The set is now out-of-service for 15-45 minutes. There is
visual notification of the process on the set.
8. The upgrade process starts.
9. When that set is finished, a message is sent to the Expec stating the
firmware version.
10. The Expecs then checks the next set for “idle state”, erases the
current firmware from the set, and the upgrade process starts.
11. Steps 6-9 are repeated until all the selected sets are upgraded.
