Resetting Display Settings Using V-Key Reset
If the display settings are inappropriate for the particular monitor that is connected, it is
possible that the display will not function properly when the thin client restarts. To correct
this, power-on the thin client while continuously tapping the V key. This will restart the thin
client with a display resolution of 640 x 480 pixels and a 60 Hz refresh rate.
Accessing Thin Client BIOS Settings
While starting a Wyse thin client you will see a Wyse logo for a short period of time. During
this start-up you can press Del to enter the BIOS of the thin client to make your
modifications (enter Fireport as the password).
Enabling a Disabled Network Setup Dialog Box
Although there are privileges and user modes associated with user access to thin client
resources, access to network setup (using the Network Setup dialog box) depends upon
privilege level. A Stand-alone user either is by default a user with High privilege or has a
thin client that is locked down. A Guest user has an implicit privilege of None and all
access is governed by that privilege. A PNAgent/PNLite-only user has whatever privilege
was set in the wnos.ini file at thin client boot, whatever privilege was locked down at the
last access of a wnos.ini file, or High privilege (by default).
If the Privilege parameter is set to Low or None in the INI files, the thin client Network
Setup dialog box will be disabled (the user cannot access it). In such a case, there may be
occasion to access the Network Setup dialog box without wanting to change the INI files.
For example, an occasion when you need to change to another FTP or Virtual Desktop file
server or add to the PNAgent/PNLite servers list. To access the Network Setup dialog
box in such a case, disconnect the network cable and reboot the thin client to Stand-alone
user mode. The Network Setup dialog box displays after the thin client initializes and you
can then make the required entries (be sure to reconnect the network cable and reboot
when finished).
Caution
If a thin client accesses the enterprise intranet through Dial-up, PPPoE, or
PPTP VPN and the thin client is locked-down, a Non-privileged or
Low-privileged user attempting to reboot to Stand-alone User mode will
disable the Network Setup dialog box and System Reset capabilities. The
user will then be unable to re-access the enterprise intranet through this
path. If this happens, the thin client must be moved to a location where it can
access the enterprise intranet directly (Ethernet cable) and reboot so that
you as an administrator can make any required changes to the thin client
operating configurations (for example, set the INI files to unlock the thin
client).
If the thin client is configured for Dial-up access, there must be an RAS
server answering the configured telephone number. Otherwise, the thin client
will require factory attention to recover it.
