#ne80e

The MPU on the NE80E/40E is currently installed with a 1GB memory bar manufactured by vendor A. The MPU memory now needs to be expanded to 2GB through additional installation of another 1GB memory bar. After one 1GB memory bar manufactured by vendor B is installed in the MPU, it is displayed that the MPU memory is still 1GB. 

NOTE:

This troubleshooting case is not applicable to the NE80E/40E-X1/X2.

1, Remove and then install the memory bar manufactured by vendor B from or in the MPU. Then, run the display memory-usage command, and you can find that the memory is still 1GB. This rules out the possibility that the memory bar manufactured by vendor B is improperly installed.

2,  Replace the memory bar manufactured by vendor B with another memory bar manufactured by vendor B. The display memory-usage command displays that the memory of the MPU is still 1GB. This rules out the possibility of failures of the memory bars manufactured by vendor B.

3,  Remove the memory bar manufactured by vendor B, and then install two 1GB memory bars to the MPU. Then, the display memory-usage command displays that the memory on the MPU is 2GB. The fault is thus rectified.

The memory of the NE80E/40E MPU is currently 1GB. To meet service requirement, another 1GB memory bar must be installed. The newly installed memory bar, however, is incompatible with the existing memory bar of the MPU. Therefore, the newly installed memory bar cannot be identified. After a 1GB memory bar of the same vendor with that of the existing memory is installed to the MPU, the memory of the MPU is displayed as 2GB.

Procedure

1, Remove the memory bar manufactured by vendor B, and then install two 1GB memory bars manufactured by vendor A to the MPU.

After the operations, run the display memory-usage command displays that the memory on the MPU is 2GB. The fault is thus rectified.
