3 System Administration

This chapter provides system administration information, remote management

information, and detailed system command and parameter configurations, to help you

design and manage a Wyse

Winterm

1 series Thin Client environment.

Note

The password for the BIOS is Fireport.

Updating Software

The software version is embedded in both the RAM and flash memory images. This

version information is used to compare the images on the FTP server to the

currently-loaded flash image on the thin client. A major revision number supersedes a

minor revision number when making the comparison. In turn the minor version number

takes precedence over the build number.

After obtaining software updates from Wyse, you must replace the existing software

images in the wnos subdirectory on the FTP server to allow the thin clients to

automatically detect and self-install the new software (upon thin client system start). The

FTP server address and exact path to these files are specified in DHCP Options 161 and

162 (if DHCP is not used, the path is specified in the Network Setup dialog box).

Each time a thin client boots, it checks the software images on the FTP server, and if

configured, automatically performs an update if a newer version is detected. Whether or

not an update is performed depends on the AutoLoad setting in the Global profile

(wnos.ini) as described in "Using the User Profile ini File Command Set." The image

names and date-time stamps determine whether or not the update is newer than the

version currently installed on the thin client.

There is a significant distinction between using DHCP and not using DHCP to access the

various necessary files.

• If DHCP is used, the thin client software automatically inserts the path component /

wyse following what it receives from the DHCP server (unless the path is terminated

by a $); this is done only if a value is received from DHCP.

• If DHCP is not used and the configuration is done manually, the full path up to the

wnos component must be inserted; there is no automatic /wyse insertion and no $

processing.

• For users familiar with the Wyse 3 series Thin Clients, the Wyse 3 series equipment

does processing on both DHCP and manual input, as well as $ processing (as $ is a

legal meta-character in manually entered strings). Wyse Thin OS software does not

recognize a $ terminator as a legal meta-character in a locally entered string.

Note

Citrix does not supply an ICA client for the Wyse thin client platforms. Citrix

ICA auto-update does not function for the ICA client installed on the thin
