Removing and Replacing the A41 Hard Disk Drive (HDD)
Certain unique files exist on the hard disk drive that are necessary for proper operation of your analyzer.
These files must be copied to another location to allow them to be installed onto the new HDD after it has
been installed.
If you are replacing the HDD, not just removing the hard disk drive assembly (HDDA) to allow access to other
assemblies, the following procedure must be performed first.
If you are not replacing the actual HDD, proceed to “Tools Required,” on this page.
Copy Unique Files from the Hard Disk
1. Insert a USB flash memory drive into a USB port.
2. Open Windows Explorer.
3. Navigate to C:\Program Files\Agilent\Network Analyzer.
4. Copy each of the following files from the hard disk drive to the USB drive:
•gen.lic
• user_calkitfile
• All files prefixed with mxcalfile_.
• Any personal user files that you wish to preserve.
5. Remove the USB drive from the USB port.
6. Exit Windows Explorer.
Tools Required
• T-10 TORX driver (set to 7 in-lb; for hard disk drive replacement)
• T-10 TORX driver (set to 9 in-lb; for all other T-10 applications)
• ESD grounding wrist strap
Removal Procedure
1. Disconnect the analyzer power cord.
Refer to Figure 7-17 for the remainder of this procedure.
2. With a T-10 TORX driver, loosen the four HDDA mounting screws (item
①
) on the rear panel.
3. Remove the HDDA from the analyzer by pulling on the finger grip (item
➁). The HDDA interconnects
with a connector inside the analyzer rear panel so moderate force may be necessary to disengage this
connector.
