M3900 Flash Download Page 267 of 504
Telephones and Consoles Description, Installation, and Operation
M3905 telephones acquired by the Symposium Call Center Server (SCCS) do
not have to be de-acquired (pulled out of all queues) before the flash
download is started. However, during the download, the agent using the
M3905 telephone is placed in a maintenance-busy state for approximately 12
minutes. As a result, the SCCS is not able to record any agent statistics for
agents using the M3905 telephones during the download. The SCCS agent
reports for the interval in which the download occurred will, therefore, be
inaccurate.
PSDL installation
During a flash download, the system downloads the contents of a PSDL/
PSWV file to an M3900 telephone. This PSDL Installation Procedure can be
used to load a new PSDL/PSWV file on the system in place of totally
reinstalling system software. If there are concerns about system downtime in
regards to performing software upgrades in cases where only a new PSDL/
PSWV file is needed, this process allows the replacement of the PSDL/
PSWV file only. For detailed information on the PSDL installation
procedure, refer to Communication Server 1000S: Upgrade Procedures
(553-3031-258).
Dynamic PSDL installation
The system supports Dynamic PSDL installation. It is no longer necessary to
update all PSDL files to obtain the latest firmware. A loadware patch with
new PSWV can be installed. The patch installation replaces the existing
PSVW file and rebuilds the PSDL file. The new M3900 firmware files are
available through the Enterprise Solutions PEP Library (ESPL) website.
Four new pdt commands support the Dynamic PSDL feature:
• -lwload <loadware patch filename(s)>
— loads one or more loadware patches on the switch.
• -lwinst <loadware patch number(s)>
— rebuilds psdl.rec to include new loadware
