Appendix G – Upgrading
This appendix explains how to use the Nokia
Access Point Upgrade utility to upgrade your
Nokia A032 via a PC workstation connected to
the serial port via a null-modem cable (also
known as a data transfer cable).
You would do this in the following cases:
• If your client machine doesn’t have TCP/IP
installed; in this case you can’t use TFTP to
upgrade the Nokia A032 via the LAN
• If you need to upgrade the Nokia A032’s
system BIOS; the Nokia Access Point
Upgrade utility is the only way to do this.
The Nokia Access Point Upgrade utility only
runs under Microsoft Windows 95/98/2000 or
NT.
Overview
The Nokia A032 uses flash memory for storage
of important information including the
operating firmware of the unit. Flash memory
has the advantage that the memory contents
are not lost when the unit is powered off.
However, the contents can be changed by a
special procedure. This allows the firmware in
the unit to be upgraded in the field – a big
advantage.
In addition to the flash memory, the Nokia
A032 stores configuration information in
special RAM called non-volatile RAM.
Important!! You need
a null-modem cable
(also known as a data
transfer cable) to
communicate via the
serial port.
Note: Upgrading the
system BIOS should
only be done on
instructions from
Nokia or your dealer.
