4.4 Potential Pitfalls
When an RFP is configured via OM Configurator and is taken out of an
installation the RFP may become unusable:
● When this RFP comes up it finds a valid configuration in its permanent
memory. It will hence skip DHCP for booting.
● But when this configuration is not valid anymore (e.g. the TFTP-server
has a new IP address meanwhile) the RFP isn't able to complete the
boot and is hence not able to connect to the OMM.
● The RFP will not get newer passwords from the OMM.
It is therefore recommended to switch of the OM Configuration before taking
an RFP out of an installation. But nevertheless the OM Configurator allows to
reset the permanent memory of an RFP (the Aastra DeTeWe support must
be connected).
