## Hot-swapping of peripheral boards

### General

This chapter explains the procedures for exchanging and adding a peripheral board in ASB150 02 without switching off the power. These procedures cannot be applied to CPU-D4/CPU-D5, IC-LU, VMU-D and AUX boards.

### Prerequisites

In order to use the hot-swapping function, the software of ASB 150 02 must be based on Release 10 or higher (minimum FECU KDUBS 130 06/1 must be connected to CPU-D4 board). Boards can only be replaced by boards of the same type, however they might offer different functions. The different functions can be based on a different number of individuals, different jumper settings or different hardware components (e.g. FECU or Compact Flash Card). New boards may be inserted in a vacant position only. If BMS is connected via a modem, it is not possible to perform any hot-swapping action.

### Limitations

The hot-swapping function can not be applied to the CPU-D4/CPU-D5, IC-LU, VMU-D and AUX boards

### Exchanging of boards

To exchange one or more board(s) in a running system, please follow the five steps below:

1. Connect the BMS to the system
2. Shut down of boards
3. Replacing of boards
4. Re-programming of boards (if needed, see chapter Special considerations when shutting down peripheral boards)
5. Check and erase warnings in the warning-log, which may have occurred because the board has not been available during hot swapping.

#### Shut down of boards

The shut down command must be executed before removing one or more board(s), in order to avoid a system restart.

The boards can be shut down in the ’Hardware Details’ dialog or in the individual ’Card Information’ dialog.

Note

In order to shut down a board, it must be registered in the E2 memory of the CPU-D4/CPU-D5. It is neither possible to shut down MISPLACED or MISSING boards nor boards of a wrong type.
Before shutting down an IC-CU_ board, the data should be saved by using the Cordless System Manager (CSM) or the BMS (only IC-CU2). After replacing the IC-CU_ board, the configuration data from the previously installed board has to be uploaded again, otherwise all cordless telephone sets need to be re-programmed again.

##### Shutdown of boards in the ’Hardware details’ dialog

1. Select ’Boards’ in the tree view, to open the context menu
2. Click on “Hardware details”
3. Mark the desired boards which are to be shut down (for example the MFU board)

1. Click the ’Shut down’ button, to deactivate the marked board(s)

##### Shut down of boards in the ’Card Information’ dialog’

1. Click on the desired board in the tree view to open the ’Card Information’ dialog

1. Click on the ’Shut down’ button to deactivate the board

If the shut down should not be performed immediately, enter a time frame between 0 and 11 minutes. When this time has expired, all active processes on the board will be terminated.

#### Replacing of boards

1. After you have shut down a board, wait until the new status will be shown in the ’Hardware details’ or ’Card Information’ dialog.
2. Exchange the board against a new one of the same type
3. Activate the board again
   ’Hardware details’ dialog: Mark the board and click on the ’Update’ button
   ’Card Information’ dialog: Click on the ’Activate’ button

After the process has been completed, BMS receives an acknowledgement and this result is shown in the ’Hardware Details’ or in the ’Card Information’ dialog, containing all the data of the operational board (PROM version, revision, etc.).

Note

Before exchanging an IPU board against a new one, it is necessary to inform the LAN administrator about the new MAC address of the IPU board. This activity is necessary if command 2151 is set to BOOTP or DHCP in order to secure that the new IPU card will get the prior defined IP-address from the server. If the BOOTP or DHCP server is not updated with the new MAC-address, the IPU board will start up but will not get an IP-address assigned from the server.
In order to solve this problems one the following scenarios can be chosen:
A) Update the BOOTP or DHCP server with the current MAC address and perform an
individual board restart
B) Change command 2151 to the value ’no protocol’, configure the commands 2152, 2153, 2154
manually with the prior values and perform an individual board restart.

### Adding of boards

To add one or more board(s) in a running system, please follow the steps below:

1. Add the new board into a vacant board position
2. Connect the BMS to the System
3. Select ’Boards’ in the tree view to open the context menu
4. Click on ’Search new cards’
   BMS checks all board positions marked empty. If a new board in an empty slot is found, it is marked as misplaced. The new board(s) will be reported to BMS and will be shown in the ’Hardware Details’ dialog (see below).

Note

When the search function is activated, all AUX-3 boards will be re-started (regardless of whether newly inserted or already existing in the system).

1. Initialize the board
   ’Hardware Details’ dialog: Mark the misplaced board(s) and click on the ’Update’ button. (e.g. the MFU)
   ’Card Information’ dialog): Click on the ’Initialize’ button.

After the process has been completed, BMS receives an acknowledgement and this result is shown in the ’Hardware Details’ or in ’Card Information’ dialog, containing all the data of the operational board (PROM version, revision, etc.).

Because the new board(s) is/are initialized with some default data only, the (re)programming of the board(s) may be necessary. After initialization (and re-programming, if needed) is finished, the board(s) and all individuals are ready for traffic.

### Special considerations when shutting down peripheral boards

#### ELU-*, MFU or IC-CU_ boards

##### Operator Instrument

On an operator instrument calls can be parked on the loop keys, the OP-hold key and the monitor key. If at least one incoming external call is parked on these keys during the shut down process of the board, it is rerouted back to the operator queue. Any other type of parked call, will be terminated during the shut down process. If there are no more active operator instruments available for the OP-queue, all calls within the queue are re-routed to the shut down re-route position.

##### Tandem Configuration

If the master of a Tandem Configuration is shut down, no calls can be made to the slave extension. If the slave of a Tandem Configuration is shut down, calls can still be made to the master.

##### Activated Diversions

If an extension has activated any kind of diversion (e.g. follow-me) to a directory number that is currently shut down, the diversion of incoming calls will not be executed and it also not possible to activate any kind of diversion to a directory number which has been shut down.

#### BTU-A boards

If a BTU-* board with one or more connected music sources is shut down, all extensions and operators currently connected to one of these music sources (background music or music-on-hold) are switched to silence channels.

#### VMU-HD / MFU boards

##### Shutdown of a VMU-HD / MFU board

On a shutdown request all registers as well as all voice channels are blocked, so that no new requests to seize voice channels are possible and all queued voice channel requests are cancelled. All registers on the board are marked as busy. Therefore these registers cannot be seized any longer. This is exactly the same as for shutdown of a BTU-D board.

As soon as a call and a process is finished, all individual(s) affected will be blocked automatically. Not all calls with queued voice channel requests will receive a channel, so these calls have to continue after the voice playing part, or need to be re-routed. After the selected shut down time-out elapses, all channels still playing announcements will be terminated by the system.

##### Reactivating of a VMU-HD / MFU board

When reactivating a VMU-HD/MFU board, the system (min. Release 12) verifies the previous settings of command 4603 (Record announcements allowed). If the value has been set to YES, the command 4450 (Loading voice announcements) will be executed automatically and all references to the voice announcements on the storage media of the VMU-HD/MFU will be rebuilt.

Note

This does not apply for a new board in a previously vacant position. In this case 4603 and 4450 always have to be set.

4603 |  | Record announcements allowed

4450 |  | Loading of voice announcements (only accessible via system telephone set)

In case of messages and individual greetings, the technician has to decide whether or not the rebuild of references shall also be applied. This decision is necessary as the system can not recognize whether the storage medium of the VMU-HD/MFU has been reused from the previous board or also has been exchanged for a new one.

.

- Press NO, if a faulty VMU-HD / MFU board has replaced by a new one however, the old storage medium with the existing voice announcements, voice messages and individual greetings and have been kept.
- Press NO, if the prior shut down was performed in order to extend the storage medium with additional voice announcements.
- Press YES, if a faulty storage medium has been replaced by a new one. According to the files on the new storage medium the references to the announcements will be rebuilt. All references to the voice messages and individual greetings will be deleted in the system.

Note

If YES is pressed although the storage medium has not been changed, all references to the voice messages and individual greetings will be deleted in the system. This process does not cover the immediate deletion of the files on the storage medium of the VMU-HD / MFU board. These unused files will be detected by the VMU reference check which takes place every 15 minutes.
If NO is pressed although the storage medium has been changed, the references of the voice messages and individual greetings will be kept. If a software function tries to use one of these voice references, then this will fail as the files do not longer exist on the storage medium. In this case it is necessary to shut down the VMU-HD / MFU and to click on YES (storage medium has been changed) when activating the board again.
