2Installing Z Class Flash
This chapter contains information for users of Wyse Z class thin clients who must
install new flash. If you are installing firmware only, you can skip this chapter and
proceed to "Installing WES7p Firmware."
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 side with four flat screws is facing
downward. Using the Phillips Screwdriver remove the two screws from either end
near the back panel, and then remove the three screws from the cover along the
back panel edge, as shown in Figure 2.

4. Place your thumbs on the top surface above where the end 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, as shown in Figure 3.

5. (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 4.

6. Remove the cover to expose the flash module, as shown in Figure 5.
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. (a) Align the cover screw tabs with screw holes and press downward; (b) slide cover
toward the front of the thin client, as shown in Figure 6.

10., Attach the screws in the reverse order as described in step 3.
11.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.”
