Caution (for Brazil only)   The use of the outlet strip with overvoltage protection with part number C39334-Z7052-C33 is absolutely mandatory. The AC power of the system cabinet(s) must be conducted through the outlet strip with overvoltage protection.

Step	Activity
1.	Plug in the power supply cable for the system cabinet(s).   Note (for Brazil only): The AC power of a system cabinet is internally equipped with transient overvoltage protection up to approx. 2kV. Since additional lightning protection is prescribed for Brazil, the AC power of the system cabinet(s) must be conducted through the outlet strip with overvoltage protection (part number C39334-Z7052-C33). In this way, transient overvoltage protection is guaranteed up to approx. 4 kV.
2.	Position all LUNA2 power supply switches to "DC-ON".   Note: Startup does not begin until the switches on all LUNA2 units are in "DC-ON" position.
3.	Monitor the RUN LED of the CBSAP. The individual steps of the system boot (Table 5-2) can be observed this way.

Table 5-2

RUN LED - LED Status Meaning

RUN LED	Meaning
Off	No power
On	Reset switch pressed briefly
Off	Reset switch held down for more than 5 seconds (LED is extinguished to acknowledge that a reload has begun)
On	System boot
Off for 0.1 s	Load operation: APS in SDRAM, loadware, and card data
Flashing 0.5 s on/0.5 s off	Normal operating state (zero load)1
Flashing 0.1 s on/0.1 s off	MMC removed or defective

1The flashing rhythm depends on the load. The higher the system load the slower the flashing rhythm.

The HiPath 3800 is ready when the date "1. JAN 00" and the time "00:00" appear in the display on the system telephone.

If	Then
Missing or defective board	No action.
Different board type	The system does not automatically activate the board.
Underequipped or same board variant	Board is activated. The same station range is used.
Over-equipped board variant	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.
New board in empty slot	•   Board was the last one installed in accordance with the placement sequence: All boards are activated and the numbering plan continues without a gap.  •   Board was inserted ahead of another board in the placement sequence: Board is activated and appended to the last board in the numbering plan.

Step	Activity	Description
1.	Disconnect the system from the power supply. Check that the system is de-energized.   Expand as required.
2.	Connect system to power supply	A continuous numbering plan is generated (as was the case when the system was first initialized).   Notes:    •   Changes to the extension numbers result in changes to the individual, extension-specific data.  •   Only those ports provided for in accordance with the maximum configuration are activated if the maximum line configuration is exceeded (too many trunk boards).  •   A mixture of subscriber line circuits and trunk lines on one S0 board can result in gaps in line numbering. This is because all S0 ports are initially activated as trunks and are only subsequently reconfigured.
