Installation
This section will guide you on how to install the expansion chassis to your
notebook.
Installing the Expansion Chassis
To install the expansion chassis, follow the steps below:
1. Remove the 14 screws securing the bumpers.
➢ISOT-M3.0X10L (marked with orange-white circle): 6 screws
➢ISOT-M3.0X7L (marked with blue-white circle): 8 screws
2. Remove the bumpers.
3. Pry to remove the mylar from the lower case.

4. By aligning with the screw holes, install the expansion brackets onto their
respective slots.
NOTE
•Ensure that the 4 O-rings ( ) are properly embedded on the upper part
of the screw holes (marked with the blue-white circle).
5. Attach the 4 screws (ISOT-M2.6X4L) to secure the expansion brackets to the
lower case.

6. Connect the PCIe coaxial cable to the mainboard connector. Then connect
the PCIe power cable to the mainboard connector and secure the latch.
7. Route the PCIe power and coaxial cables through the opening on the
expansion chassis. Then, place the expansion chassis on the top of the lower
case. Ensure that the screw holes are properly aligned.
NOTE
•If you have difficulty aligning the screw holes, lift the chassis and loosen
the 4 screws securing the expansion brackets (see Step 5). Then place the
chassis onto the lower case and re-align the screw holes (marked with

red-white circle) with the screw holes on the brackets.
After verifying the screws holes are properly aligned, lift the chassis again,
and then fasten the 4 screws to secure the expansion brackets.
8. Attach the 4 screws (ISOT-M2.6X3L) first to secure the expansion chassis to
the lower case. Then continue to attach the remaining 6 screws
(ISOT-M2.6X8L).
➢ISOT-M2.6X3L (marked with blue-white circle): 4 screws
➢ISOT-M2.6X8L (marked with orange-white circle): 6 screws
NOTE
•Ensure that the O-ring is embedded with the ISOT-M2.6X8L screw ( ).

9. Flip the expansion module board and peel the protective film off from the
thermal pad.
NOTE
•If the thermal pad falls off, make sure to attach it back into place.
CAUTION!
Be careful not to touch the thermal grease when handling the thermal pad.
10. By aligning with the screw holes, install the expansion module board onto its
slot.

11. Attach the 5 screws (ISOT-M2.6X4L) to secure the expansion module board
to its chassis.
12. Connect the other end of the PCIe coaxial cable to the expansion module
board connector. Then connect the other end of the PCIe power cable to the
expansion module board connector and secure the latch.
13. Secure the cables with the cable clip.

14. Assemble the standard PCIe card holder with the standard PCIe card bracket.
Then secure the standard PCIe card assembly using the screw
(ISOT-M4.0X6L).
Repeat the same procedures to assemble the low-profile PCIe card assembly.
Standard PCIe Card

Low-profile PCIe Card
NOTE
•The standard PCIe card and low-profile PCIe card are optional accessories.
15. Align the standard and low-profile PCIe card assemblies with the expansion
module board connectors and slide in place. Ensure that the PCIe card
assemblies are properly seated in place.

16. Attach the 4 screws (ISOT-M2.6X4L) to secure the PCIe cards holders.
NOTE
•For the full-length PCIe card, besides securing the PCIe card holder, you
will also need to attach another 2 screws (ISOT-M3.0X7L) (marked with
orange-white circle) to secure the PCIe card to the expansion chassis.

17. With the protruding tabs facing down, install the rubber gasket onto its
compartment. Press down each tabs to ensure that the gasket is properly
seated in place.
CAUTION!
To ensure the correct placement and orientation, please observe the
printed direction (marked with green line) when installing the rubber
gasket.
18. By aligning with the screw holes, install the bottom cover onto the expansion
chassis.
NOTE
•Ensure that the protruding parts of the bottom cover (marked with the
red-white frame) are properly positioned with the respective location of
the IO doors.

19. Attach the 14 screws (ISOT-M2.6X4L) to secure the bottom cover.
20. By aligning with the protruding parts of the bottom cover, install the
low-profile and standard IO doors onto their respective slots on the bottom
cover.

21. Place the door brackets onto their respective compartments on the installed
IO doors. Ensure that the protruding parts and screw holes are properly
aligned.
22. Attach the 7 screws (ISOT-M2.6X4L) to secure the IO doors.
