M3900 Series Meridian Digital Telephones Description, Installation and Administration
• When a system is first brought into service with M3900 sets, there is a
significant amount of messaging that occurs to activate the sets through
the Lamp Audit background routine. The time required to bring all sets
into service on a system is dependent on the system configuration, and
could take several hours. Performinga Flash Download directly after the
system is brought into service adds to the message load on the system.
Therefore, it is recommended that M3900 set download activities not
occur in conjunction with systems beingbrought into service. Instead
downloads should occur 24 hours after a system is brought into service.
• If a user attempts to use a set duringa flash download, all set activity is
ignored.
• When performinga flash download to an M3900 port that does not have
a set installed, or downloadingto an M3900 port that has the wrong
M3900 set type installed, an SDL2110 error message is printed out at the
system.
• Duringthe middle of flash download operation, if the set is disconnected
or if the set fails download for any reason, the set is rendered inoperable.
Flash downloadingmust run to completion before the set can be made
operable.
• For the manual individual download operation, if the set is not
responding(is not operational) or if the set is not a M3900 set, flash
download fails.
• If the firmware file(s) used as the source for flash download to M3900
sets are not present (in the proper location) on the Meridian 1 system
disks, the flash download operation fails.
• While a system-wide flash download operation is in progress, attempts
to disable sets that are currently beingdownloaded result in an SCH 1958
message that is printed with the list of sets involved. If a loop, shelf, or
card that contains the sets beingdownloaded is disabled, then the
download to the sets on that loop, shelf, or card fails.
• Accordingto the existingPSWV logic, when PSWV is in progress, an
attempt to load an overlay is denied and result in an OVL0306 message
.
