HiPath 3800 lets you remove and insert peripheral boards during operation (hot plugging). The following startup rules apply.

Rules for removing and inserting boards  
Caution  
To ensure that the system operates without blocking, you must follow the rules in Section 4.1.5 "Installing Boards (Configuration Notes)" concerning board configuration.  

 Table 9-1   Startup Rules for Inserting and Removing Boards
 If  
 Then  
 Inserting new board in free slot  
Board is integrated into the system according to the rules for initial startup (Section 4.1.5.6 "Initializing the Boards").  
 •   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.
