Section 10.2.2.4. Deleting an Access Point

10.2.2.4. Deleting an Access Point

If an access point is to be removed from the configuration (in the example: AP 43), the following sequence must be complied with:

If payload survivability is configured, it must first be checked whether the access point to be deleted provides the trunk access for a source group. If it does, a suitable replacement must be found.
If payload survivability is configured and a source group becomes superfluous when an access point is deleted, the LCR must be adapted and the source group deleted if necessary.

	Configuration Management > System Data > IPDA > IPDA - Payload Survivability Click Search, select the access point and Delete.
	`DELETE-APRT:TYPE=ALTROUT,SRCGRP=3;`

Deletion of all peripheral modules configured within this access point (presupposes that no subscribers are configured on that module, etc.)
If signaling survivability is configured for this access point:

Delete the assignment of this access point to a survivability router

	Configuration Management > System Data > IPDA > IPDA Access Point Click Search and select the access point. Delete the desired router number on the General tab under Signaling Survivability and Save.
	`DELETE-APRT:TYPE=SURV,CONF=AP,LTU=43;`

If special routes are configured: (Section 2.5, “Special Routes”)

Delete the corresponding entries in the routing tables of other access points, if these entries lose their validity for additional access points.

In the example in Figure 21 “Special routes between access points”, the route via Router Rz becomes superfluous if AP 43 is deleted. If, however, AP 98 was deleted instead of AP 43, the route would have to remain in place, as it is also valid for AP 99.

	Configuration Management > System Data > IPDA > HG3575 Additional Routing Click Search and select the access point. Enter zero addresses (0.0.0.0) in the lines of the routing table that are to be deleted and Save.
	`DEL-APRT:TYPE=ROUTTBL,MTYPE=NCUI,LTU=99,INDEX=1;` Note: No distinction is made here between hardware types. NCUI applies to NCUI2 and NCUI4.

Deactivating the access point with USSU:

	Configuration Management > System Data > IPDA > IPDA Access Point Click Search and select the access point. Click Deactivate on the Action pull-down menu.
	`DEACTIVATE-USSU:LTU=43;`

Deactivating the IP connection of the access point with USSU:

	Configuration Management > System Data > IPDA > IPDA System Data Click Search and select the access point. Click Execute on the Action pull-down menu and select the mode of action Update AP, confirm with OK.
	`EXEC-USSU:MODE=DELAP,LTU=43;`

Deleting the access point (CM):

Configuration Management > System Data > IPDA > IPDA Access Point

Click Search and select the access point, then click Delete.

Deleting the IP network configuration of the access point:

DELETE-APRT:TYPE=APNET,LTU=43;

Deleting the access point with UCSU:

DELETE-UCSU:UNIT=AP,LTU=43;

IMPORTANT:

If the removed access point was configured for AP Emergency (i.e. it was assigned an emergency group), you must observe the following: The IP address of the removed access point can only be reused when this change has been saved on all CC APs, in other words, when “cloning“ is completed using OpenScape 4000 Assistant > Backup & Restore.
