Removing the E6L Engine Core
MLN-192 cards are installed in the E6L engine core, which slides
out of the E6L chassis.
To remove the E6L engine core
1Put on your anti-static wrist band and configure it according to
its instructions.
2Shut down your system, and disconnect any cables connected
to your E6L engine.
3Place your E6L on a table or other flat surface that provides
enough room for the E6L engine core to be removed comfort-
ably. Make sure your surface is clear of any debris.
4On the back of the E6L, loosen the four thumbscrews that se-
cure the core to the engine chassis.
Images shown in this guide (such as cable colors or hardware
configuration) may not exactly match your E6L.
Unlike AVB-192 and WSG-HD cards, no internal Ethernet
jumper cables are required for the MLN-192 card.
If your E6L engine is installed in a rack and there is enough
room inside the rack to access the inside of the core, instead
of completely removing the core you can slide it out until it
catches, and then proceed with installation.

the latches they are attached to are fully extended, as shown in
Figure 2.
6Using the handle, slowly slide the core partially out, locate the
interior catch on the right side of the tray, and press it to release
the core from the chassis.
7Slowly slide the core out of the E6L chassis completely, and
place it on your work surface.
Remove AVB-192 Network Cards
E6L-192 and E6L-144 Only
Before installing an MLN-192 Card in an E6L-192 or E6L-144,
both AVB-192 Network Cards must be temporarily removed.
If you are installing into an E6L-112, skip to “E6L-112” on
page 5.
To remove AVB-192 Network Cards:
1Disconnect the short Ethernet cable that connects the upper
AVB-192 Network Card (slot 2/middle) to the lower AVB-192
Network Card (slot 1/lower). Set the cable aside (you will
re-install it later).
2Disconnect all cables connected to the AVB-192 Network card
in slot 1/Master.
• Disconnect the small power cable assembly at left from its
connector on the AVB-192 card. Use your thumb to depress
the catch, then pull to disconnect the cable.
• Disconnect the Ethernet cable that connects the E6L to the
AVB-192 card.
3With all cables removed, \loosen the exterior captive thumb-
screw that secures the faceplate of the Network 2 AVB card to
the E6L, then repeat for the Master AVB card.

4Using a #2 Phillips screwdriver, loosen the rear bracket cap-
tive thumbscrews that secures the back of the AVB-192 Net-
work cards to the chassis.
5Starting with the upper AVB-192 card, release the card from
its PCIe slots by doing the following:
• With one hand, lift the tab on the retaining clip to release the
card from its clip.
• With your other hand, pull the card out of its PCIe port.
6Slowly lift the back of the card upwards along the bracket (you
might need to use your other hand to pull the bracket back
slightly so the card can clear its guide slots).
7Carefully remove the card from the core and set it aside.
8Repeat the previous steps for the lower AVB card.
Back Bracket and Option Card
Bracket
The MLN-192 Card package includes one Back Bracket and one
Option Card Bracket. These are included for card installation into
older, original E6L engines. Newer E6L Engines will already
have these brackets pre-installed.
Back Bracket If your E6L-192 or E6L-144 Engine Core has the
original Back Bracket (shown below), you must replace the old
bracket with the included new Back Bracket. Note that the origi-
nal bracket has only three receivers for card-retaining thumb-
screws, while the new bracket has five.
Option Card Bracket If your E6L-192 or E6L-144 Engine Core
has the original Option Card bracket, you must replace the origi-
nal bracket with the new Option Card Bracket included with the
MLN-192 Card.
If your E6L engine has an old Back or Option Bracket go to
“Appendix A: Brackets” on page 13 and follow the instructions
there to replace the brackets. Then return here to continue install-
ing the MLN-192 card.
If your E6L engine already has the newer brackets proceed to
“Install the MLN-192 Card” on page 4.

MLN-192 Option Card Installation4
Install the MLN-192 Card
MLN-192 Card installation differs depending on the type of E6L
engine. Follow the instructions in the section appropriate for your
E6L engine:
• “E6L-192 and E6L-144” on page 4
• “E6L-112” on page 5
E6L-192 and E6L-144
With E6L-192 and E6L-144 engines the MLN-192 Card must be
installed in slot 7. (Slot 6 is reserved for WSG-HD Waves Sound-
Grid cards only.)
The E6L-192 and E6L-144 engine core has eight half-length
PCIe slots for Option cards. When standing at the back of the E6L
engine, slots 1–5 are at the lower right and slots 6–8 are in the
middle (below the AVB slots) as shown in Figure 11.
To install an MLN-192 Card:
1Remove the faceplate from slot 6 by loosening its captive
thumbscrew and then pulling it out of the slot.
2Remove the MLN-192 Card from its packaging and hold it by
its edges.
1Using a #2 Phillips screwdriver, loosen the two captive thumb-
screws that secure the Option Card bracket to the chassis and
set the bracket aside.
2Inside the unit, place the face of the card into position in slot 7,
with the back of the card tilting upwards.
Using two hands, hold the front of the card in place in the slot
with one hand, and slowly move the back of the card down-
wards along the back bracket until the card is horizontal.
3From the back of the core, make sure the faceplate of the Op-
tion card is correctly aligned with the open slot cover.

tive screws.
10 Proceed to “Re-Install the AVB-192 Cards” on page 9.
E6L-112
If you are installing an MLN-192 card into an E6L-112, the
MLN-192 card can be installed in Expansion slot 1, or into AVB
Network slot 3.
The MLN-192 card is shipped from the factory ready to be in-
stalled in an Expansion slot 1. However, if you already have a
MADI-192 card installed in Expansion slot 1, or plan to install a
MADI-192 in the near future, you can replace the factory face-
plate on the MLN-192 card and install it in Network slot 3.
E6L-112 engines support a maximum of two Option cards, in-
stalled into Expansion slot 1 and/or Network slot 3, as explained
in “Appendix B: E6L-112 Card and Slot Configurations” on
page 15.
Note: WSG-HD is only supported in Network slot 3 in E6L-112.
Determine which E6L-112 slot you want to use, then proceed to
either of the following:
• “Installing MLN-192 Card into Expansion Slot 1” on page 6
• “Installing the MLN-192 Card into Network Slot 3” on page 8
Figure 16. Retaining clip closed, when card is fully seated
Figure 17. Securing the card to the back bracket
Tightening the rear bracket captive thumbscrew can make it
difficult to re-install other cards above the MLN-192 card. If
this occurs, leave these rear bracket captive thumbscrews un-
attached until all cards are re-installed, then tighten them to
secure each card to the back bracket.
Figure 18. Securing the Option Card bracket in the correct orientation
When installing a single MADI-192 card into an E6L-112,
the MADI card must be installed in Expansion slot 1.

Installing MLN-192 Card into Expansion Slot 1
(E6L-112 Only)
To install the MLN-192 card into Expansion slot 1:
1Looking inside the core from the right side, locate the E6L
card retaining bracket.
2Locate the thumbscrew that secures the bracket to the bottom
of the unit and loosen it completely.
3Locate the two Phillips head screws on the top of the bracket,
remove them, carefully remove the bracket, and set them all
aside.
4From the back of the core, remove the faceplate from Expan-
sion slot 1 by loosening its captive thumbscrew and then pull-
ing it out of the slot.
5Recommended: Disconnect the power cables connected to
HDX cards installed above the Option card slots and tuck them
out of the way. It is possible to install cards into Expansion
slots without disconnecting these cables, as long as you are
careful to not stretch the cables or damage their connectors
while installing the cards.
6Remove the Option card guide bracket by doing the following:
• Fully loosen its single thumbscrew (shown below).
• Slide the bracket to the right, towards the front of the E6L
core, until it clears the two bracket alignment posts.
• Carefully lift the guide bracket out of the core. You do not
need to re-install the bracket but do not discard it in case
you decide to add a MADI-192 card in the future.
7Remove the MLN-192 card from its packaging and place it on
your padded surface. Be careful to handle the card by its edges
only.

8Remove the captive thumbscrew assembly from the rear end
of the card.
Be sure to store this assembly in case you need it in the future
(such as after moving the MLN-192 card to a Network slot).
9Holding the MLN-192 card by its edges, align the card’s face-
plate in the slot opening of the core and align the card’s PCIe
connectors with the corresponding PCIe expansion slot, then
firmly press the card into the PCIe slot.
Make sure the card is fully seated in the PCIe slot and that the
white retaining clip clicks into position. You can check by
looking underneath the card.
10 From the back of the core, make sure the faceplate of the
MLN-192 card is correctly aligned with the open slot and then
secure the card to the core by tightening the captive thumb-
screw.
11 If you disconnected any power cables to DSP cards, reconnect
them now. Also, make sure the power cables to DSP cards are
safely positioned as shown below, along the back edge of the
MLN-192 card (not along the side).
12 Next, re-install the card retaining bracket. The bracket has
plastic slots on its interior, the top-most of which needs to be
aligned with and receive the edge of the MLN-192 card.

• Carefully place the card retaining bracket back into posi-
tion, making sure to not disturb the surface of the DSP cards
in the process or pinch any cables.
• Make sure the toe on the front-facing edge of the bracket is
in its slot on the bottom of the core.
13 Tighten the captive thumbscrew securing the bracket to the
bottom of the E6L engine core.
14 Replace the two screws at the top of the retaining bracket.
Installing the MLN-192 Card into Network Slot 3
(E6L-112 Only)
It is recommended to install the MLN-192 into Network slot 3 in
E6L-112. This leaves Expansion slot 1 available to add a
MADI-192 card later. However, if your E6L-112 already has a
WSG-HD card installed in Network 3, install the MLN-192 card
into Expansion slot 1 (see “Installing MLN-192 Card into Expan-
sion Slot 1” on page 6).
The E6L-112 compatible faceplate, included with the MLN-192
card, must be installed before installing the card in AVB Network
slot 3.
To install the faceplate for E6L-112 AVB Network slot 3:
1Place the card on your padded work-surface face-down.
2Using a #2 Phillips screwdriver, remove the two screws that
secure the faceplate to the card. Keep the screws nearby to use
to secure the new faceplate.
3Remove the faceplate and set it aside.
4Turn the MLN-192 card over so it is face-up.
5Take the new E6L-112-compatible AVB Network faceplate
and place it against the MLN-192 card. Make sure it is oriented
correctly and that its mounting tabs sit below the card.
6Using the two screws you removed earlier, secure the faceplate
to the card from the top.

Keep the faceplate in case you want to move this card into
an Option card slot in the future.
This differs from how the Option slot faceplate is attached to
the card; tabs on the AVB Network faceplate sit below the
card and are secured from above, while those on the Option
faceplate sit above the card and are secured from below.

MLN-192 Option Card Installation 13
Appendix A: Brackets
The MLN-192 Card package includes one Back Bracket and one
Option Card Bracket. These newer brackets are pre-installed in
all recently manufactured E6L engines. If you have an older E6L
engine that does not yet have these newer brackets, follow the in-
structions below.
Back Bracket If your E6L-192 or E6L-144 Engine Core has the
original Back Bracket (shown below), you must replace the old
bracket with the included new Back Bracket. Note that the origi-
nal bracket has only three receivers for card-retaining thumb-
screws, while the new bracket has five.
Option Card Bracket If your E6L-192 or E6L-144 Engine Core
has the original Option Card bracket, you must replace the origi-
nal bracket with the new Option Card Bracket included with the
MLN-192 Card.
Replace the Back Bracket
To remove the old bracket:
1Make sure you have removed all AVB-192 Network Cards as
instructed previously.
2Using a #2 Phillips screwdriver, remove the two fasteners
from the top of the back bracket. Set the fasteners aside (you
will use them to secure the new bracket).
3Using a #2 Phillips screwdriver, loosen the two captive thumb-
screws that secure the back bracket to the interior wall of the
engine core.
Before loosening the second thumbscrew be sure to hold onto
the bracket with your other hand to prevent it from falling onto
other components.
4Remove the old bracket (it can be discarded).
To install the new back bracket:
1Orient the bracket in position as shown, making sure its upper
tabs are under the upper tabs on the chassis.
Use your fingers to start the upper captive thumbscrew,
enough to hold the new bracket in place.
2Using a #2 Phillips screwdriver, align and insert the two cap-
tive thumbscrews on the back bracket into their threaded re-
ceivers on the inner wall of the core.
For the lower thumbscrew, a 12-inch long #2 Phillips screw-
driver is recommended.
