Chapter 9. Updating Device Firmware
ClearCube recommends always using the same firmware version on zero clients and host cards.
See PCoIP Firmware Compatibility Guide, available on the ClearCube Support site, for detailed
information about PCoIP firmware versions and compatibility.
You can update firmware on ClearCube PCoIP devices by uploading self-installing firmware files
to zero clients and hosts. Devices (except as noted below) use files with the .ALL file extension.
NOTE: TERA1-based Quad systems (I9440 zero client and quad host cards V5300-series and
lower) use firmware files with the .ZIP extension. See Rev B of this guide for more
information about TERA1-based quad devices and COMM firmware. Note that TERA1-
based dual devices and TERA2 devices do not use COMM firmware.
Update individual devices from the device’s Web interface or from Sentral. You can also use
Sentral to update device groups (that is, multiple devices). See Sentral Administrator’s Guide for
information about firmware updates, device groups, and more.
The following sections detail the steps to update the firmware on individual devices using the
device’s Web interface (perform each section in order):
1. Satisfying prerequisites as described in 9.1 “Update Prerequisites” on page 105
2. Identifying the version of the firmware currently on the device as described in 9.2 “Identify
Firmware on Device You Are Updating” on page 105.
3. Uploading the firmware file to the device and allowing the file to install as described in
9.3 “Upload Firmware to Device” on page 106.
4. Resetting the device as described in the “CAUTION” message on page 95
5. Verifying installation as described below
The following sections describe each of these steps.
