1. Optional: If the SUBRACK_ID_MISMATCH alarm is found, adjust the DIP switches on the EFI1 board in the corresponding subrack in line with the subrack ID planning to set the ID of the subrack to a value that matches the subrack ID displayed on the LED on the SCC board in this subrack.
2. Reset the NE or the subrack with reference to Step 4.
Step 9 Upload the NE configuration data to the U2000. Insert a physical board in the slave subrack and add the corresponding logical board on the U2000. Check whether the board is available and operate normally (displayed as green). If yes, the configuration of the master/slave subrack is correct.

4.14 Setting Master/Slave Subracks for OptiX OSN 8800 T16
The equipment supports the master/slave subrack management. To prevent subrack ID conflict and avoid the communication error, set the IDs of the master and slave subracks correctly. The ID of the master or slave subrack is set through the EFI board in the subrack.
Prerequisite
The U2000 server and client should be started normally.
The master/slave subracks should be installed.
Fiber connection should be done.
Tools, Equipment, and Materials
U2000
Background Information
The master subrack and the slave subrack are connected through the ETH1/ETH2/ETH3 of the EFI. The EFI board can be used to set the ID of a subrack. The default ID of a subrack is 0. The setting is implemented by DIP switches. The value that can be set by using each of the two DIP switches on the EFI board is a binary value 0 or 1. ID1-ID4 correspond to bits 1–4 of SW2, and ID5-ID8 correspond to bits 1–4 of SW1. Among these ID values, only ID1-ID6 are valid. The bits from high to low are ID6-ID1, by which a maximum of 64 states can be set. Currently, the first 32 states are used. As shown in Figure 4-5, the value represented by the ID6-ID1 is 000001, which is 1 in decimal system. That is, the subrack ID is 1.
l Along the direction reaching from a point close to the T1, the two DIP switches are numbered SW1 and SW2.
l When the DIP switch is toggle to ON, the value of the corresponding bit is set to 0.
NOTE
For details on the principle for configuring the master and slave subracks, see "Master-Slave Subrack" in the Product Description.

The LCD front panel of the AUX indicates the ID of the subrack. The ID of the master subrack is 0 and the ID of the slave subrack ranges from 1 to 31.
On the U2000, the master subrack and the multiple slave subracks are displayed as one NE with one ID and one IP.
Precautions
CAUTION
Changing the subrack ID is a dangerous operation, which may interrupt service.
Procedure
Step 1 Check the subrack IDs displayed on the LCDs on the AUX boards in the master and slave subracks. If two subrack IDs repeat each other, it indicates a subrack ID conflict. If a subrack ID displayed on an LCD blinks, it indicates a subrack ID mismatch. In either case, adjust the DIP switches on the EFI board in the corresponding subrack in line with the subrack ID planning so that the DIP switches setting for each subrack is unique.
NOTE
After the adjustment of the DIP switches (change of the subrack ID) is complete, perform a power-off reset on the NE or the subrack. For details, see step Step 4.
Step 2 Log in to the U2000.
Step 3 Double-click the optical NE to display the Running Status of the ONE.
Step 4 Right-click the NE and select NE Explorer to display the NE Explorer.
1. If there is repetition or blink of the master subrack ID in step 1, perform a power-off reset on the NE after the DIP switches adjustment.
2. If there is repetition or blink in slave subrack ID in step 1, after DIP switch adjustment, warm reset all boards in this slave subrack, or power-off reset the NE.
NOTE
l During deployment commissioning, the reset operation can be realized by rebooting the subrack power supply. For example, to reset the NE, you can switch off the power supplies of all master and slave subracks, and then switch on the power supplies when all boards stop operating.
l To prevent service interruption during upgrade for capacity expansion, you can perform a reset operation as follows: First, perform a warm reset on all boards in the original subracks. Then, change the ID of the subrack where the subrack ID conflict or mismatch occurs. At last, reboot the power supply of this subrack.
Step 5 In the Running Status of the ONE, right-click the NE select Browse Current Alarms to display
