S6L Control Surface: Replacing the AVB Board
This document provides instructions for replacing the AVB board in the S6L Control Surface.
Before you Begin
Make sure to do all the following items before beginning the procedure.
1Make sure you have assembled all Required Tools and Items.
2Put on your anti-static wrist band and configure according to its instructions.
3Shut down your system, and disconnect any cables connected to your S6L control surface.
4Make sure your work area is clear of any debris.
Required Tools and Items
• 1x 2.5mm Hex driver
• 1x #2 Phillips screwdriver (for S6L-16C only, 12-inch magnetic-tip #2 Phillips recommended)
• Anti-Static wrist strap (not included)
• S6L-24C and 16C Only: 5 mm nut driver or open end wrench
• S6L-24C Only: 1x 9/32 nut driver
• Small cups or other containers to hold and organize the different types of fasteners as you remove them from the unit
• S6L-24C and 16C Only: Large towel or similar on which to set the Top Cover
• Table or other work surface strong enough to support the S6L control surface while allowing access to the back. For S6L-16C,
make sure the table provides at least 30 cm (+/- 12 inches) at the back of the control surface to set the PSU.
• USB keyboard and mouse
• Recommended for labeling cables: Camera (your phone or other) to document cable connections, or a pen and lightweight
tape to label cables as you disconnect them
What’s Included
• 1x Replacement AVB board assembly
Throughout this procedure, keep the removed screws organized to simplify re-assembly.

1. Prepare the S6L Control Surface
Prepare the S6L control surface by removing the back cover (all models) and disconnecting Light cables (S6L-24C and 16C only)
as explained in the following sections.
Remove the S6L Back Cover
The steps required to remove the back cover vary depending on the model of S6L control surface.
S6L-48D, 32D, and 24D
To remove the Back Cover from S6L-48D, 32D, or 24D:
1Using a 2.5mm Hex driver, remove the fasteners that secure the back cover to the S6L chassis and set the screws aside.
• S6L-48D uses 12 fasteners
• S6L-32D uses 10 fasteners
• S6L-24D uses 8 fasteners
2After removing the fasteners try sliding the back cover off the chassis by pushing it down with your hands and simultaneously
pulling the cover away from the chassis.
If the cover does not slide freely, try inserting a small flathead screwdriver along its upper edge as shown in Figure 2 and try to
work one side free and then the other.
3Slide the panel away from the control surface, and set the panel aside.
4Proceed to 2. Remove the SBC Tray.

S6L-24C and 16C
To remove the covers from S6L-24C or 16C:
1Using a 2.5 mm Hex driver, loosen or remove both the right and left End Caps by loosening the 7 fasteners securing the caps to
the chassis.
At minimum, one End Cap needs to be loosened enough to let you remove the top cover later in these instructions. If you remove
either (or both) of the End Caps completely, carefully disconnect the LED power cable before moving the cap away from the
chassis.
2Using a 2.5mm Hex driver, remove the fasteners that secure the back edge of the back cover to the S6L chassis and set the screws
aside.
• S6L-24C uses 8 fasteners
• S6L-16C uses 6 fasteners
3After removing the fasteners try sliding the back cover off the chassis by pushing it down with your hands and simultaneously
pulling the cover away from the chassis.
4Slide the panel away from the control surface, and set the panel aside.

5Using a 2.5mm Hex driver, remove the fasteners that secure the top cover to the control surface.
• S6L-24C and 16C both use 4 fasteners
6Set a large towel or similar across the upper modules of the control surface (CKM, MTS, MLM) to protect them.
7Carefully lift the top cover off the chassis and set it face down on the towel you placed on the surface, being careful to not stretch
or stress the cables connected to the light sockets.
8Proceed to Disconnect Light Cables.

Disconnect Light Cables
(S6L-24C and 16C Only)
Before removing the SBC tray you must label and disconnect the two Light cables connected to the Top Panel.
To disconnect the Light cables:
1Do the following:
• On S6L-24C disconnect the cables at the connectors shown below.
• On S6L-16C, disconnect the cables at the connectors shown below.
2Proceed to 2. Remove the SBC Tray.

2. Remove the SBC Tray
The SBC Tray must be removed from the chassis before replacing the AVB board assembly or any of the I/O boards.
To remove the SBC Tray:
1If present, remove the black rubber stopper from the purple plastic shroud, and set it aside. This stopper was present on early S6L
control surfaces, and must be removed to access one of the captive screws that secures the SBC Tray to the chassis. It does not
need to be re-installed (you can discard it if desired).
2With the stopper removed, use a #2 Phillips screwdriver to loosen the captive screw below the stopper hole.
3Using a #2 Phillips screwdriver, remove the two fasteners securing the top edge of the purple shroud to the top of the chassis.

424C Only: On some S6L-24C control surfaces the LVDS cable needs to be freed from the tray and disconnected before the tray
can be removed. If your 24C has a short LVDS cable, do the following.
• Using a 9/32 nut driver, remove the nut securing the LVDS cable to the tray then remove the cable clamp from its bolt.
• Carefully unplug the LVDS cable from the SBC. Use your finger of fingernail (or a small tool if the connection is too tight)
to disconnect the plug on the end of the cable from the connector on the board; do not pull on the wires.
5Locate the captive screws securing the SBC Tray to the chassis (these are in addition to the captive screw under the shroud that
you loosened earlier).
• S6L-48D, 32D, 24D, and 24C have four captive screws to loosen, shown below:
• S6L-16C has two captive screws to loosen (at the far left and far right in the image, above).

6Using a #2 Phillips screwdriver, loosen the captive screws.
7If cables in your unit are bound with a cable tie similar to that shown below, cut the cable tie (this will allow the SBC Tray to
be removed).
8(S6L-16C Only) Move the PSU out of the way to be able to remove the SBC tray by doing the following:
• Using a 12-inch magnetic tip #2 Phillips screwdriver, remove the two fasteners that secure the lower back of the PSU to the
bottom of the control surface chassis (between the lower back of the PSU and the chassis interior wall).
• Using a 2.5mm Hex driver, stand at the back of the control surface and remove the four fasteners that secure the PSU Bay to
the back of the S6L chassis.

• From inside the chassis, push the PSU assembly out far enough to be able to grab the flanges then carefully pull the PSU as-
sembly almost all the way out of the chassis (you do not need to remove it). Use a block or similar to support the PSU assem-
bly.
In the next step you will lift the Tray out of the chassis and hang it off the back edge of the console chassis. You should not need
to disconnect any cables before lifting the Tray out (other than S6L-24C LVDS as described previously), but you may need to guide
one or more cables away to allow the Tray to be lifted out of the chassis. If you find you do need more slack, note and/or label and
then disconnect any cable that isn't long enough to allow the Tray to be lifted out of the chassis.
9Being very careful to not stretch any cables, use two hands to lift the tray out of the chassis. Tilt the Tray as needed to clear the
chassis, and make sure no cables are caught or stretched.
10 Align the edge of the Tray with the edge of the chassis and hook the Tray on the edge as shown in Figure 17 so that the Tray
hangs off the chassis.

11 Do the following for better access to the AVB board assembly:
• Being careful not to stretch or strain any cables or connectors, slide the SBC Tray to the left and guide its cables to the left so
they do not block access to the AVB board assembly.
• If any SBC cables are too short to let you position the SBC or its cables out of the way, photograph and/or label and then dis-
connect those cables (labeling the cables ensures you will be able to re-connect them to their correct ports after completing the
procedure).
S6L-48D, 32D, and 24D
Proceed to 3. Remove the Old AVB Assembly.
S6L-24C and 16C Only
Continue with the following instructions to remove the BaseBoard Lite.
Remove the BaseBoard Lite
(S6L-24C and 16C Only)
On S6L-24C and 16C you must remove the BaseBoard Lite before you can replace the AVB assembly.
To remove the BaseBoard Lite:
1Disconnect the Molex power cable from the BaseBoard Lite (see “1” in the figures below).
2If you did not disconnect the two light connectors at the top panel, disconnect them from the BaseBoard Lite now to simplify
removing the board.
• S6L-16C has additional cables that need to be disconnected, shown below. Photograph and/or label each cable to simplify
re-connecting them later.
