FAQ
1. What can I do if the device is no longer accessible?
·
If the Status LED is red, the device has no connection to the switch. Unplug and plug
the Ethernet cable. If the Status LED is still red, try other switches. If one uses no
switch, but connects e.g. a laptop directly to the device, make sure you are using a
crossover Ethernet cable.
·
If the status LED is orange for a longer time after unplugging and plugging the Ether-
net cable, then DHCP is configured, but no DHCP server was found in the network.
After a timeout, the last IP address is configured manually.
·
If there is a physical link (status LED is green) to the device, but you can not access
the web server, bring the device into bootloader mode and search for it with
GBL_Conf.exe
. Then check the TCP-IP parameters and change them if neces-
sary.
·
If the device is not found by GBL_Conf.exe in bootloader mode, you can reset the
settings to factory defaults
as the last option.
2. What can be done if the device is no longer accessible, but the buttons still re-
spond?
·
Entering or leaving the bootloader mode does not change the state of the relays. In
the chapter Maintenance
there is a description how to activate the bootloader by
pressing the buttons and how to exit the bootloader afterwards. This will restart the
firmware without switching relays. However, this procedure does not help if the net-
work itself is incorrectly configured.
3. Where is the serial number stored in the device?
The serial number is not stored in the device, but only visible on the device label.
However, you can display the MAC address in the IP address configuration
. If you
contact Gude Systems Support with the MAC address, we will be happy to give you the
corresponding serial number.
4. Why does it sometimes take so long to configure new SNMPv3 passwords on
the website?
The authentication methods "SHA-384" and "SHA-512" are calculated purely in soft-
ware, and can not use the crypto hardware. On the configuration page, e.g. "SHA-512",
needs up to 45 seconds to calculate the key.
