Q: How to hot swap the MPU of NE5000E/80E/40E correctly?
For active MPUs of NE5000E/80E and those of NE40:
1. First perform active/standby switchover before drawing out active MPU.
2. Execute power off slot <ID> in command line.
3. Wait for power-off of LPU, and then draw it out.
For NE80E and NE5000E, if it is not active MPU, and for NE40E if it is not active SRU:
1. Execute power off slot <ID> command in command line.
2. Wait for power-off of LPU, and then draw it out.
