Upgrading the System
1
There are two types of system upgrades:
■
Feature Upgrade. To upgrade your system to the latest “release” or
version as soon as it becomes available. With little or no changes in your
existing equipment or wiring, your system can be easily adapted and
expanded as your company’s business needs change and grow.
■
Maintenance Upgrade. To fix problems in the system.
In Release 3.0 and later, an upgrade basically involves inserting a memory card
(similar to a computer diskette) into a slot on the system’s processor or “brain”
(part of the system’s
control unit). For a feature upgrade, you need a new memory
card; for a maintenance upgrade, Lucent Technologies provides the memory card
at no cost to you.
The memory cards are color-coded and have different titles to indicate their
contents and function:
■
Feature Upgrade Memory Card. Orange label with black bars; entitled
Forced Installation. To upgrade your system to the latest release.
■
Maintenance Upgrade Memory Card. Orange label; entitled
Upgrade
Card. To fix problems in the system.
NOTE:
A third type of memory card has a white label and is entitled
Translation
Card. This memory card is used to back up and restore your system
programming as described in
“Backing Up the System” on page 6–39
.
For more information about upgrading your system, contact your Lucent
Technologies representative.
Environmental Requirements
1
The control unit requires a regulated environment that is temperature-controlled,
clean, and not exposed to direct sunlight. In addition, proper power and grounding
are essential for correct and safe system operation, and to protect the system
against lightning, power surges, and other problems.
If the control unit and other system components were installed by qualified Lucent
Technologies technicians, these requirements were met during installation.
