Performing upgrades

WARNING
For complete details on performing upgrades, refer to the appropriate
Installation and Administration Guide for your specific product.
ATTENTION
Nortel Networks recommends that you perform a firmware upgrade if you are
using older versions of firmware (Release 1.3.4.x or earlier). To check the
version of firmware you are using, do one of the following:
If you are not connected to the device, open Configuration Manager and
!
connect to the Remote Office unit. A window displays the RLC or Remote
Office unit firmware version.
If you are already connected to the device, choose System Information
!
System Data. The unit firmware version displays.
1.4.2 Release Notes for Remote Office and RLC
To eliminate any confusion in board numbering, the RLC
automatically sets its Unit ID to 254 with this release when
upgrading from releases prior to 1.2.0.
The RLC now identifies the Remote Office units by their Unit
ID, not by their Unit Number or Node Name. If the Unit ID is
not the same as the Unit Number in the Remote Connection
Configuration on the RLC, the Unit ID in the 9150 or 911x
System Configuration sheet must be changed to match the
Unit Number or Node Name.
To maintain compatibility with all installations that support a
single Remote Office unit, the upgrade process assigns the
default Unit ID of "1" to each unit to match the default at the
RLC. Following an upgrade, administrators responsible for
multiple Remote Office units on a single RLC must configure
the correct Unit ID at each Remote Office unit.
The protocol for communication between the RLC and the
Remote Office units requires that they be running the
same version of firmware for them to communicate with
each other.
