2.4.5
Assignment of wrong IP addresses, malfunction (NANL-B500G-RE)
must not be inserted via a switch or
hub directly into a corporate network with other devices, as long as the
analyzer device is operating in
server operation mode. Otherwise, it
may lead to wrong assignment of IP addresses and malfunction.
The analyzer device NANL-B500G-RE works by default as an external
DHCP server in the
operation mode and independently
assigns IP addresses to other devices. This may happen also to devices,
which are not concerned by the netANALYZER measurements.
In order to connect the analyzer device NANL-B500G-RE to any network,
ensure that
DHCP server operation mode
is disabled.
2.4.6
Power drop during write and delete accesses in the file system
The FAT file system in the netX firmware is subject to certain limitations in
its operation. Write and delete accesses in the file system (firmware
update, configuration download etc.) can destroy the FAT (File Allocation
Table) if the accesses cannot be completed if the power drops. Without a
proper FAT, a firmware may not be found and cannot be started.
Ø
Make sure, that the power supply of the device does not drop during
write and delete accesses in the file system (firmware update,
configuration download etc.).
2.4.7
Exceeding the maximum number of permitted write and delete
accesses
This device uses a serial flash chip to store remanent data such as
firmware storage, configuration storage, etc. This device allows a maximum
of 100,000 write/delete accesses that are sufficient for standard operation
of the device. However, writing/deleting the chip excessively (e.g. changing
the configuration or changing the name of station) leads to the maximum
number of permitted write/delete accesses being exceeded and to device
damage. For example, if the configuration is changed once an hour, the
maximum number is reached after 11.5 years. If the configuration is
changed even more frequently, for example once a minute, the maximum
number is reached after approx. 69 days.
Avoid exceeding the maximum permitted write/delete accesses by writing
too often.
