Agilent PNA Series Hard Disk Drive Replacement

CAUTION

If you are unfamiliar with HDD removal and replacement, refer the work to qualified personnel.

NOTE	It is required that you return your old HDD to Agilent Technologies. If security procedures prevent you from returning the HDD, it must be destroyed.

Copy Unique Files from the Hard Disk

Certain unique files exist on the hard disk drive (HDD) 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.

1. Insert a writable floppy disk into the floppy disk drive, or 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 floppy disk or the USB drive:
   • gen.lic
   • user_calkitfile
   • All files prefixed with mxcalfile_.
   • Any personal user files that you wish to preserve.
5. Remove the storage device containing the backup files: either the floppy disk from the analyzer’s disk drive, or the USB drive from the USB port.
6. Exit Windows Explorer.

NOTE	The following Disassembly and Reassembly procedure applies to the E8362A/63A/64A, E8362B/63B/64B/61A, and N5230A models. For the E8356A/57A/58A, E8801A/02A/03A, and N3381A/82A/83A, please see below.

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.
2. With a T-10 TORX driver, loosen the four Hard Disk Drive Assembly (HDDA) mounting screws on the rear panel.
3. Remove the HDDA from the analyzer by pulling on the finger grip. The HDDA interconnects with a connector inside the analyzer rear panel so moderate force may be necessary to disengage this connector.

Disassembling the Hard Disk Drive Assembly (HDDA)

Refer to Figure 1.

1. With a T-10 TORX driver, remove the four screws (item 1), and the eight bushings (item 2), that mount the HDD (item 4), to the bracket.
2. Disconnect the HDD (item 4) from the interface board (item 3).

Figure 1 Hard Disk Drive Assembly (Exploded View)

Reassembly Procedure

Refer to Figure 1.

1. With the disk drive bracket right-side up (it is shown upside down in Figure 1), insert four bushings (item 2) into the four holes in the bracket.
2. Connect the new HDD (item 4) to the interface board (item 3) by holding the HDD on its edges and pushing it firmly into the connector on the interface board. Take special care to align the connector pins. Applying power to a misaligned connection will permanently damage the HDD.
3. While holding the HDD in place, turn the bracket over and insert the other four bushings (item 2), into the other side of the same four holes specified in step 1.
4. Install the four screws (item 1), finger tight, through the eight bushings (item 2), to attach the HDD to the bracket.

   With a T-10 TORX driver, snug-tighten the four screws in a Z-pattern, and then torque them, in the same pattern, to 7 in-lb.

Do not yet install the HDDA into the PNA.
Go to Update the BIOS.

Update the BIOS

This procedure requires a BIOS Update Floppy Disk. If you do not have one, you can easily create one by downloading and executing this BIOS floppy creation utility. Do not place this file on the floppy disk. Instead, place it on your PC and execute it. It will then instruct you to insert a floppy disk which it will then image.

1. Insert the BIOS Update Disk into the floppy disk drive.
2. With the HDD removed, turn on power to the analyzer.
3. Since there is no HDD installed, the analyzer will automatically boot from the BIOS Update Disk located in the floppy disk drive. The BIOS update process will run automatically. The entire process takes approximately one minute. Make sure that power to the analyzer is not interrupted during this process.
4. When the BIOS update process has completed, press and hold the analyzer’s power button (approximately five seconds) until the analyzer turns off.
5. Remove the BIOS Update Disk from the floppy disk drive.

Reinstalling the HDDA

1. Slide the HDDA into the slot in the rear panel and push it firmly into place to engage the connector.
2. With a T-10 TORX driver, tighten the four HDDA mounting screws.

1. Slide the HDDA bracket feet into the slots in the frame.
2. Place the interface board into position and, with a T-10 TORX driver, tighten the two mounting screws.
3. Place the HDDA into its permanent location.
4. With a T-10 TORX driver, install the HDDA mounting screw.
5. Replace the inner and outer covers.

Initialize the Windows Operating System

1. Connect a mouse and keyboard to the analyzer.
2. Turn on power to the analyzer.
3. The operating system initialization process will run automatically. Part way through the process, you will be prompted to accept the Windows licensing agreement. The entire process takes approximately six minutes, during which the analyzer will reboot up to three times.
4. After the PNA application screen is displayed, there may be a display to remind you to upgrade the firmware. If so, click OK to continue.

Set Up the Agilent Administrator Password

The PNA network analyzer comes with an Agilent administrator account already installed. This account is used by our service centers to gain access to the analyzer without needing to know the customer's password. This account must NOT be removed.

The Agilent account has a password which is unique for each PNA. When the hard drive is replaced, this unique six-digit password must be set. To determine the code for your PNA, use the utility below.

The network analyzer must be powered up and operating for this procedure.

1. On the Windows Desktop, right-click on My Computer, and then click Manage.
2. In the Computer Management window, navigate to System Tools, Local Users and Groups, Users.
3. Right-click on Agilent, click on Set Password.
4. Enter the six-digit password in the Password and Confirm Password boxes. Click OK.
5. Right-click on Agilent, click on Properties.
6. Unselect all checkboxes. Select Password never expires. Click OK.
7. Close the Computer Management window.

Install Backup Files onto the New Hard Disk Drive

The files that were previously saved onto a floppy disk or USB memory drive must now be installed onto the new HDD. The network analyzer must be powered up and operating.

1. Insert the storage device containing the backup files: either the floppy disk into the floppy disk drive, or the USB memory drive into a USB port.
2. Click on START. (It may be necessary to exit the Network Analyzer application.)
3. Point to Programs, Accessories, and then open Windows Explorer.
4. Navigate to C:\Program Files\Agilent\Network Analyzer.
