Removing and replacing FRUs

Field Replaceable Units (FRUs) are modular hardware components that can be serviced without disturbing other components in the system. The following topics discuss working with the Turbo iDDR FRUs.

The pictures in these topics show how to disassemble. Unless otherwise documented, re-assembly is the reverse.

Unless otherwise indicated, you need only a Torx tool with T15 magnetic tip to remove and replace parts in the Turbo iDDR.

You can also replace the entire Turbo iDDR as a FRU, as explained in "Replacing an iDDR".

NOTE: Only Grass Valley components are supported. Do not attempt to use components procured from a different source.
NOTE: Do not discard any hardware unless specifically instructed to do so.

WARNING: To avoid serious injury from high currents, ensure that the power cord is disconnected prior to removing or replacing any parts.

CAUTION: This system contains board-level components that must be protected from static discharge and physical shock. Wear a wrist strap grounded through one of the system's ESD Ground jacks when handling system components.


Top cover removal

To access the internal hardware, first remove the top cover as follows:

CAUTION: To avoid possible damage to circuit boards and other sensitive parts, turn off the iDDR and disconnect AC power before opening the top cover or removing any internal parts.

For an overview orientation of internal FRUs, refer to "FRU locations".



Front bezel removal

To remove the bezel, first remove the top cover, then proceed as illustrated.

NOTE: When installing the bezel, make sure the bottom tabs are engaged and the button openings are aligned before tightening screws.


Rotary encoder removal

To remove the rotary encoder, first remove the top cover and bezel, then proceed as follows:

  1. If your iDDR has a rotary encoder bracket, remove the bracket screws from the side of the chassis, as illustrated, and remove the bracket.

Shown with DVD drive removed for clarity.

  1. Remove the fasteners and the cable, as illustrated.

  1. Remove the rotary encoder from the chassis.

Removable media drive removal

To remove the DVD drive or the REV/DVD drive combo, first remove the top cover and front bezel, then do the following:

  1. Identify the connections to the DVD drive or the REV/DVD drive combo, then proceed as instructed in the following options:
    • If you have a Turbo-1 model (with DVD drive only), there is one ribbon (IDE) cable connecting to the DVD drive. This is the case if your Turbo system has either the Type I motherboard or the Type II motherboard. In this procedure when there is a choice of diagrams, follow those that apply to the DVD drive, as the steps are the same for both types of motherboards.
    • If you have a Turbo-R model (with REV/DVD drive combo) and the drives are connected with just one ribbon (IDE) cable, your Turbo system has a Type II motherboard. In this procedure when there is a choice of diagrams, follow those that apply to the Type II motherboard.
    • If you have a Turbo-R model (with REV/DVD drive combo) and there are two ribbon (IDE) cables (one for each drive), your Turbo system has a Type I motherboard. In this procedure when there is a choice of diagrams, follow those that apply to the Type I motherboard.

Also refer to "CPU motherboard identification".

  1. Disconnect cables as in the following diagrams:

DVD drive (with either type of motherboard)

REV/DVD combo with Type I motherboard

REV/DVD combo with Type II motherboard

NOTE: Some iDDRs with the REV/DVD combo and Type II motherboard have a different ribbon (IDE) cable fold and connection pattern than that shown. If your iDDR is different, keep the pattern as is when replacing the REV/DVD combo. Do not refold the cable or change connections in an attempt to match the illustration.

For the detail of IDE cable connections on the motherboard, refer to "CPU motherboard removal"

  1. Remove the DVD drive or the REV/DVD drive combo from the chassis.

  1. Disassemble brackets and/or drive carriers as in the following diagrams:

DVD drive

For the DVD drive, you must exchange the bracket with the replacement unit, as in the following illustration.

REV/DVD drive combo

For the REV\DVD drive combo, you must remove the faulty drive from the bracket. When you do so, retain the bracket, as you must use it again with the replacement unit.

Use the following diagram to disassemble the REV\DVD drive combo:

  1. Before installing the replacement drive, check the jumper. Set it in the MASTER position if not already set, as in the following diagrams:

DVD drive jumper position

REV/DVD drive combo jumper position

The REV drive jumper is in the MASTER position for both the Type I motherboard IDE cabling (two IDE cables: one for REV drive, one for DVD drive) and the Type II motherboard IDE cabling (one IDE cable with middle connector to REV drive and end connector to DVD drive).

NOTE: Some iDDRs with the REV/DVD combo and Type II motherboard have a different jumper connection than that shown. If your iDDR is different, make the jumper connection on the new REV/DVD combo the same as it is on the old REV/DVD combo. Do not change the jumper connection in an attempt to match the illustration.
  1. To install the replacement DVD drive or the REV/DVD drive combo, reverse the steps in this procedure

CPU motherboard identification

A Turbo system has either a Type I (Intel) motherboard or a Type II (Fujitsu-Siemens) motherboard. Use the information in this section to identify the type of motherboard in your Turbo system.

IDE connectors

You can identify the motherboard type by the number of IDE connectors:

RAM slot color

You can also identify the type of motherboard by the color of the slots that hold the Random Access Memory (RAM). You might need to use a flashlight or other light source to see the color.



CPU motherboard removal

To remove the motherboard, first remove all boards in the rear of the chassis, identify the motherboard type, then do the following:

  1. Disconnect cables as in the following diagrams.

Type I motherboard

Type II motherboard

  1. Remove screws as highlighted in the following diagrams:

Type I motherboard

Type II motherboard

  1. Disengage connectors from the rear panel as you remove the motherboard.


CPU motherboard installation

Replacement motherboards are Type II motherboards. The faulty motherboard that you removed was either a Type I motherboard or a Type II motherboard. Refer to "CPU motherboard identification" to identify your faulty motherboard.

To install the replacement motherboard, reverse the steps in the previous procedure "CPU motherboard removal" for the Type II motherboard, following additional steps as indicated in the following options:

If the faulty motherboard was a Type I motherboard:

Refer to "CPU motherboard identification" to confirm that the faulty motherboard that you removed was a Type I motherboard.

  1. Discard the cable previously used to connect the DVD drive or REV/DVD drive combo.
  2. Connect the DVD drive or REV/DVD drive combo using the new cable that is supplied with the motherboard replacement kit:
  3. After the motherboard is installed, you must replace the disk image on the system drive to support the Type II motherboard. To replace the disk image, use the system installer process as follows:
NOTE: The system installer process overwrites all files on the system (C:) drive.
    1. Access the Turbo iDDR Release Notes and Installation Instructions on the Documentation CD that you received with the FRU kit. You must follow the system installer instructions in the release notes.
    2. Before the first startup after motherboard replacement, insert the system installer CD in the iDDR DVD drive. You must use the system installer CD that you received with the FRU motherboard replacement kit. This puts the required disk image on the system drive to support the Type II motherboard.
    3. Restart the iDDR.
    4. Follow the system installer instruction in Turbo iDDR Release Notes and Installation Instructions.
    5. To save your current media clips and iDDR configuration files, in the system installer application, select the System Update/Repair option.

If the faulty motherboard was a Type II motherboard:

Refer to "CPU motherboard identification" to confirm that the faulty motherboard that you removed was a Type II motherboard.

Chose one of the following options and proceed as instructed:

NOTE: On some iDDRs with the REV/DVD combo, the new ribbon (IDE) cable is folded in a different pattern than that of the old cable. If this is the case with your iDDR, you must retain and reuse the old cable. Using the new cable forces a different connection pattern at the REV/DVD combo, which renders the REV and DVD drives inoperable. Do not change the connection pattern at the REV/DVD combo.
