After reloading the customer data to the system, exit
programming mode (this could take a minute or more to save
the database), then reset the system by powering down and
back up. If the system is not reset, not all the uploaded
programming changes are in effect. Wait a few minutes for the
programming to take affect before accessing any line or special
system feature. Otherwise, some unusual LED indications may
be experienced. To prevent the USB Memory from possibly
being overwritten, remove the card after reloading the database.
Performing a Software Upgrade
This section describes the procedure to perform a software upgrade on
the CD-CP00.
♦
To save customer data prior to updating, a blank USB Memory is
required. Insert the USB Memory into the USB Port on the
CD-CP00 blade. Use Program 90-03 to save the software to the
USB Memory. Note that a USB Memory can only hold one
customer database. Each database to be saved requires its own
separate USB Drive. Use Program 90-04, with the database to be
restored installed in the CD-CP00, to reload the customer data if
necessary.
♦
After uploading programming data to the system using Program
90-04, exit programming mode (this could take a minute or more
to save the database), then reset the system by powering down
and back up. Wait a few minutes for the programming to take
affect before accessing any line or special system feature.
Otherwise some unusual LED indications may be experienced.
To prevent the USB Memory from possibly being over-written,
remove the USB Memory after downloading the database.
♦
When restoring a database file, as the slot definitions may be
different, remove all blades from the system except the CD-CP00
and CD-8DLCA/CD-16DLCA in slot 2. After the system is reset,
the blades can be reinstalled. Use Program 10-03 prior to
updating to record the current slot definitions.
♦
If the PZ-ME50 is installed on the CPU at a later date, a system
upgrade must be performed using the CD-CP00 upgrade
procedures. When a PZ-ME50 is mounted on a CPU, all software
upgrades are stored on this daughter board. If the PZ-ME50 were
to be removed from the CPU, a software upgrade must be
performed to bring the CPU to the latest version.
