2Installing D Class Flash
This chapter contains information for users of Wyse D class thin clients who must
install new flash.
Requirements
•Small Phillips screwdriver
WARNING: Flash modules may be susceptible to damage by Electro-Static Discharge
(ESD). All industry-standard cautions should be followed to avoid ESD. Before you
remove or install a module, touch any metal part of the chassis and keep that contact
with the chassis during the installation process.
Procedures
CAUTION: Follow all precautions listed in the Quick-Start Guide that came with your
thin client for disconnecting and reconnecting the thin client.
1. Perform a proper shutdown of the thin client by closing all files and ending your
session, and then pressing the power button to turn off the thin client.
2. Unplug the power cord and power adapter, and remove any other cables from the
thin client, and detach the vertical foot.
3. Position the thin client horizontally, where the Wyse logo-side with four flat screws
is facing downward. Using the Phillips Screwdriver, remove the three screws from
the cover along the back panel edge as shown in Figure 1.

4. Place your thumbs on the top surface of the opposite end where the three screws
were removed. With a continuous motion, push firmly downward and towards the
back panel (pushing down unlatches the hooks under the cover). The cover will
shift approximate 1/4 inch to hang over the back panel. (a) Grasp the overhanging
cover edge and raise the edge about 1-1/2 inches, and then (b) pull the cover out
towards the back panel at the same angle to free the opposite end of the cover from
the remaining hooks, as shown in Figure 2.

5. Remove the cover to expose the main-board shield.
Figure 3 Main-board shield
6. Using the Phillips Screwdriver, remove the five screws from the main-board shield
(four corner screws and one screw mid-way along the front edge). Remove the
main-board shield and unplug the speaker wire (red wire) to expose the main board
and Flash module as shown in Figure 4.
WARNING: Flash modules may be susceptible to damage by Electro-Static
Discharge (ESD). All industry-standard cautions should be followed to avoid ESD.
Before you remove or install a module, touch any metal part of the chassis and keep
that contact with the chassis during the installation process.

8. Install the new flash module in the reverse order of removing the original flash
module. Carefully screw down its retaining screw until it is secure.
9. Replace the speaker wire (plug in red wire) and the main-board shield (five screws).
10.Replace the cover in the reverse order as described in step 4 (align the cover screw
tabs with the screw holes and slide the cover toward the front of the thin client).
11., Attach the cover screws in the reverse order as described in step 3.
12.Connect the power cord and power adapter, attach any other cables to the thin
client, and then attach the vertical foot.
CAUTION: Do not turn on the thin client. The thin client is ready to re-image,
however the flash module does not contain an operating system. Turning on power
to your thin client without firmware will display the error message “NO OPERATING
SYSTEM FOUND.”
