Caution   When using HiPath 3550, HiPath 3350, HiPath 3500, and HiPath 3300, disconnect the system from the power supply before removing or inserting boards. Only HiPath 3800 peripheral boards can be removed or inserted during operation.

Table 12-1

Startup Rules for Inserting and Removing Boards

If	Then
Inserting new board in free slot	The board is integrated into the system according to the rules for initial startup (see Chapter 4 "Installing HiPath 3000").    •   System with default numbering plan The station numbers from the new board are appended (consecutively and in ascending order) to the numbers already assigned.  •   System with modified numbering plan The station numbers on the new board can be in any order. Using HiPath 3000/5000 Manager E or Assistant T, you can assign a specific station to a port. If the number is already assigned to a different object, you can switch both numbers.
Replacing board with same or underequipped board type	Board is activated. The same station range is used.
Replacing board with over-equipped board of same type	Board is activated. The old station range is activated and the ports associated with the new board are inserted at the end. The ports are split if there is no contiguous station range available.   In the case of subscriber line modules, you can use HiPath 3000/5000 Manager E to retain the old station data by copying it to the new board, or you can delete it and reset the default state. Copying is not possible for trunk boards.
Replacing with a different board type	The system does not automatically activate the board.   After removing the old board, you can delete it from the database using HiPath 3000/5000 Manager E or Assistant T. After you have inserted the new board, the system activates it as if it had been inserted into a free slot. However, the CDB area used by the old board is left as a gap. In the case of subscriber line modules, you can use HiPath 3000/5000 Manager E to retain the old station data by copying it to the new board, or you can delete it and reset the default state. Copying is not possible for trunk boards.

If you initiate a system reload on a system updated as described above, the system must be reset after the updated CDB has been installed. The reset synchronizes the port placement sequence in the system with that of the CDB.

Step	Activity

2.	Remove the board(s).
3.	Restart the system by plugging in the power plug.
4.	Delete board slot using user interface (29-4).
5.	Disconnect system from power supply.
6.	Insert new board(s).
7.	Restart the system by plugging in the power plug.
8.	Load customer data from the system.   Adapt customer data to new hardware configuration. Insert new board(s), (stations, for example).
9.	Load new customer data into the system.
