System 75 XE to R8si (Blowback)
This section provides the instructions for an upgrade from an R1V3 System 75 XE system to a
DEFINITY
®
Release 8si system. This upgrade includes a control-cabinet replacement.
NOTE:
You upgrade the System 75XE J58890G cabinet by completely replacing it with the R8si
J58890L cabinet.
For further information, see

Upgrade overview: System 75 XE
on page 321
Before you begin the upgrade
To prevent the most common upgrade problems, be sure that you have
•
Identified the correct TDM bus cables and terminators for the upgraded system.
•
Verified si expansion interface compatibility for packet bus applications:
If the new si system will have one or more expansion port network cabinets and will run any
packet applications, do not reuse the TN776 expansion interface circuit packs; they must be
replaced with TN570 circuit packs.
•
Checked for software upgrade compatibility and identified any patches that need to be re-applied.
•
Created the license file with RFA.
Preparation and process steps
If the system includes TN750 or TN750B announcement packs, discuss with the customer whether they
are willing to re-record announcements. Doing so can significantly reduce the time it takes to do the
upgrade. Every
save announcements
or
restore announcements
command can add up to 45 minutes
to the upgrade process. Note that you do not have to save and restore announcements on systems with
only TN750C or TN2501AP announcement circuit packs.
CAUTION:
You cannot resolve any upgrade problems without a valid craft or dadmin login and
password. You may have to contact Avaya before or during the upgrade to get the dadmin
password, and you may have to have ASG keys to use craft remotely.
For customers without an Avaya maintenance contract, the INADS database does not have a record of
passwords. Discuss with the customer who is responsible for making the passwords available.
This information in these tables applies to all upgrades. Complete the work in the
Upgrade preparation
steps
table before the upgrade. Use the
Upgrade process steps
table during the upgrade.
