FDR (Faulty Device Replacement) service
The Faulty Device Replacement service uses standard address management
technologies (BOOTP, DHCP) and the TFTP
(
Trivial File Transfer Protocol)
file
management service, with the aim of simplifying maintenance of Ethernet products.
It is used to replace a faulty device with a new device with the guarantee that it will be
detected, reconfigured and automatically restarted by the system.
The main steps in replacement are:
1
A device using the FDR service malfunctions
2
Another similar device is taken from the maintenance store, preconfigured with
the Device name for the faulty device, then reinstalled on the network. Depending
on the device, addressing can be performed using rotary selector switches (as for
Modicon STB distributed I/O
a
or Modicon OTB for example) or can be given using
the keypad integrated in the device (as for Altivar variable speed drives for
example)
3
The FDR server detects the new device, allocates it an IP address and transfers
the configuration parameters to it
4
The substituted device checks that all these parameters are indeed compatible
with its own characteristics and switches to operational mode
The FDR server can be:
