10.2.2.5. Local Configuration of an Access Point 
If an access point has been configured in the OpenScape 4000 switch,
it cannot be put into operation immediately. The central system cannot
establish contact with the access point until this has been configured
with the essential IP addresses, etc.
“Expert Access“ application is available in order to perform this
initial access point configuration locally. To this end, the TAP/Service
PC is connected to the RS232/V.24 interface of the HG 3575 with the designation
“Service“ and the application started.
The terminal login must be used for login purposes. In the case of
virgin modules, this is "TRM", and no password is set. If the module
has already been in operation and the terminal login and password have
been changed, these later values apply.
If there is a duplex processor (CC-B) in the OpenScape 4000 switch,
the address must always be specified. After all, it is not possible to
predict whether CC-A or CC-B will be playing the active role at this
time. If there is no CC-B in the system, the IP address for this processor
is not needed.
The IP address of the TAP need only be specified if the administration
function of the OpenScape 4000 switch is to be accessed from this access
point.
If VLAN tagging is used in the Ethernet segment to which the access
point should be connected, a setting must be performed for it during
initial startup. If the access point was operated in a network with VLAN
tagging and should now run without VLAN tagging, this setting must also
be changed locally.
If the access point is to be operated with fixed Ethernet interface
settings for bit rate and mode or if this fixed setting is to be removed
(in the event of relocation to another network), this setting too must
be performed locally.
Of the parameters which are displayed and adjustable, only a certain
number actually have to be entered. All other parameters are loaded from
the OpenScape 4000 switch as soon as the central system can establish
contact with the access point;
IMPORTANT:
Changing a parameter value locally does not
result in a change of the value in the system. Absolutely all parameters
configured locally at the access point are overwritten by the values
configured in the system upon loading the module from the OpenScape 4000
switch.
When configuring the access point locally, a distinction is again
also made between “networked“ and “direct link“.
