Removing and Replacing the A41 Hard Disk Drive (HDD) N5230C
Reassembly Procedure
NOTE If the HDD is being replaced by the HDDA (N8980A or N8981A), it is not necessary to
perform these steps.
If the HDD is equipped with a parallel ATA interface, follow the step below.
• With the disk drive bracket right-side up (it is shown upside down in Figure 7-18 on page 7-42), insert
four bushings (item
➁) into the four holes in the bracket.
If the HDD is equipped with a serial ATA interface, follow the step below.
• With the disk drive bracket right-side up (it is shown upside down in Figure 7-19 on page 7-43), place the
nylon spacer (item
⑤) on the bracket.
Regardless of which ATA interface the HDD is equipped with, follow the steps below.
1. Connect the new HDD (item
④
) to the interface board (item
③
) by pushing it firmly into the connector
on the interface board. Take special care to align the connector pins. Applying power to a misaligned
connection can permanently damage the HDD.
2. While holding the HDD in place, turn the bracket over and insert the other four bushings (item
➁), into
the other side of the same four holes specified in step 1.
3. Install the four screws (item
①
), finger tight, through the four bushings (item
➁), 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.
Reinstalling the HDDA
1. Reinstall the HDDA into the analyzer:
a. Slide the HDDA into the slot in the rear panel and push it firmly into place to engage the connector.
Refer to Figure 7-17 on page 7-41.
b. With a T-10 TORX driver, tighten the four HDDA mounting screws (item
①).
