FIRMWARE INSTALLATION
No firmware is installed in new A1 CPU assembly. When you replace a faulty A1 CPU
with a new one, perform the following steps to install the firmware into the A1 CPU.
Ordering the Firmware Diskette
A firmware diskette (3.5 inch) that contains the analyzer's firmware is required for the
firmware installation. If you do not have a firmware diskette, you must order one. For
ordering information, contact your nearest Agilent Technologies service center and provide
the revision of the analyzer's firmware. The part number of the firmware diskette depends
on the firmware revision. The firmware revision of the analyzer is indicated on the revision
label attached on the rear panel as shown in
Figure 6-3.
