8.1 Overview
If after power-on the SYS LED (for the position of the SYS LED see section
Positions of the LEDs, connectors and control elements [
}
page 31]) is
flashing yellow and green at a rate of 1 Hz, the device is in boot mode. The
firmware file of the netHOST device is missing or defective. In this state the
device cannot be operated and a new firmware file needs to be loaded into
the device either via SD memory card or via USB. When using the SD
memory card, all existing configuration or IP address files inside the device
will be deleted. The device will thus be reset to its “factory settings”. On the
other hand, when using the firmware download function via USB, you can
overwrite only the old defective firmware file and keep the configuration
files inside the device, thus performing only a “firmware recovery” instead of
a “factory reset”. When using USB, you can decide for yourself, whether
you also want to delete the configuration files in order to perform a full
“factory reset”.
8.2 Using an SD memory card to reset the netHOST to its “factory
settings”
The netHOST device can be reset to its factory settings by using the load
memory image on an SD memory card. You will find the load memory
image on the netHOST Solutions DVD in the
Supplements & Examples
\netHOST Device Recovery\Recovery via Memory Card
directory in the folder of your device type (e. g.
NHST-T100-DP_DPM
folder
for the NHST-T100-DP/DPM device). From there, you can copy the image
to the SD memory card, and then use the card to copy it to the netHOST
device.
All existing old data (including configuration and IP address) in the internal
load memory of the device will thereby be deleted. After recovery by SD
card, the device therefore needs a new IP address and a new
configuration.
Note:
The SD memory card is not included in the delivery of the netHOST
device, but can be obtained from Hilscher. The part number of the
card is 1719.003.
