Supply Management

Navigation Path

In the NE Explorer, select Configuration > Supply Management from the Function Tree.

Characteristics of the Supply Management

• Power-supply boards have fixed power supply partitions (for boards sets on subracks). Configure a power-supply board based on board quantity.
• Power-supply boards support short-circuiting to allow two PIU boards to share the same power supply. This reduces the number of power supply circuits and improves power supply capabilities.
• Through visualized power consumption management, the total power consumption of installed boards and the current input power consumption can be automatically calculated. This helps you view power consumption data of subracks in real time.

Function Implementation

• The Supply Management uses different colors to indicate different power supply partitions. In addition, the Supply Management uses the same color to indicate a partition and its power-supply boards, as shown in Figure 1.
  Figure 1 Supply Management
  
  
• The Supply Management displays the percentage of the total board power consumption in the total input power consumption on power supplies.
• The Supply Management supports power consumption warning thresholds and displays different colors on power supplies to indicate the remaining battery capacity based on the power consumption ratio (total board power consumption/input power consumption) and specified warning threshold.

Power Supply Partitions

Figure 2 shows the power supply partitions of the OptiX OSN 9600/9800 U64. The areas with the same background color belong to the same partition. PIU boards A1 and B1, A2 and B2, A3 and B3, A4 and B4, A5 and B5, C1 and D1, C2 and D2, C3 and D3, C4 and D4, and C5 and D5 back up each other to supply power to the subrack. Therefore, the OSN 9600/9800 U64 is not affected if an external input -48V/-60V power supply encounters faults.

Figure 3 shows the power supply partitions of the OptiX OSN 9600/9800 U32. PIU boards A1 and B1, A2 and B2, A3 and B3, A4 and B4, and A5 and B5 back up each other to supply power to the subrack. Therefore, the OSN 9600/9800 U32 is not affected if an external input -48V/-60V power supply encounters faults.

Power Supply Pool Configurations

Power Supply Pool

• Two PIU boards compose a power supply pool to supply power to service boards within the same partition. The boards in the partition automatically select one of the PIU boards as their power supply unit. For example, boards in slots IU1 to IU16 automatically select a PIU board in the A3 or A5 power supply pool as their power supply unit.
• If the terminals of power supply pools A2, A3, A4, and A5 are short-circuited, the A2, A3, A4, and A5 power supply pools form a larger power supply pool. In this way, one external power supply can supply power to two partitions at the same time.
• For the OSN 9600/9800 U64, you can make the terminals of power supply pools C2, C3, C4, and C5 short-circuited to form a larger power supply pool. In this way, one external power supply can supply power to two partitions at the same time.

Configuration Suggestions

• Select a proper configuration scenario of the power supply pool based on the power consumption specified in the network plan. Table 1 lists configuration scenarios of the OSN 9600/9800 U64, and Table 2 shows configuration scenarios of the OSN 9600/9800 U32.

  Table 1 Power supply pool configuration scenarios of the OSN 9600/9800 U64

  Non-full Configuration	Full Configuration
  NOTE: The preceding figures show the configurations of active PIU boards only. The configurations of standby PIU boards must be the same as those of active PIU boards. The non-full configurations can be upgraded to the corresponding full-configurations. No power-supply board is short-circuited on the NE by default.

  NOTE: The preceding figures show the configurations of active PIU boards only. The configurations of standby PIU boards must be the same as those of active PIU boards. The non-full configurations can be upgraded to the corresponding full-configurations. No power-supply board is short-circuited on the NE by default.

Basic Operations in the Supply Management

1. Setting a power-supply board to be short-circuited
   1. Choose a PIU board. The Supply Management displays related short-circuit relationships for you to select the target PIU board.
   2. Select the desired PIU board, as shown in Figure 4.
      Figure 4 Power supply partitions of the OSN 9600/9800 U32 subrack
      
      
   3. Click Apply to apply short-circuit relationships to the NE.
      NOTE:

      Ensure that the short-circuit relationships configured on the Web LCT are consistent with that configured on the real NE. You can use a copper bar to short-circuit two power-supply boards.
2. Setting the input current
   1. Click the button in the red box in the preceding figure. Available current values are displayed.
      
      
   2. Select the desired current value.
      NOTE:

      The available current values include 64 A, 100 A, and 120 A. The values 100 A and 120 A apply only to short-circuited power-supply boards.
   3. Click Apply to apply the configured current value to the NE.
3. Delete a short-circuit relationship
   1. Choose a short-circuit relationship. A red "X" is displayed in the short-circuit view.
      
      
   2. Click the red "X" to delete the short-circuit relationship.
   3. Click Apply to apply the deletion information to the server.
4. Setting a warning threshold
   1. Click Alert Threshold Setting. A window similar to the following is displayed.
   2. In this window, you can determine whether to enable warning or set three different power states. After that, click Apply to apply the configuration information to the NE.
