Engineer install OceanStro 9000 equipment to a customer unit (total 5 OceanStor 9000 C Node, front and rear ends are 10GE TOE networking, on-site install TOE card), the device has completed the putaway, the next will connect the signal lines, power lines, and software test due to the tight schedule, hardware installation process has the following phenomena, do you think which of the following description for these phenomena is correct? (Multiple choice)

Engineer install OceanStro 9000 equipment to a customer unit (total 5 OceanStor 9000 C Node, front and rear ends are 10GE TOE networking, on-site install TOE card), the device has completed the putaway, the next will connect the signal lines, power lines, and software test due to the tight schedule, hardware installation process has the following phenomena, do you think which of the following description for these phenomena is correct? (Multiple choice)
A . TOE network card inserted in the 5 equipment all have A0, B1 and A0, B3 two ways, because is inserted on the PCIe slots, will not affect the deployment of the system also not affect the network bandwidth, so can’t adjust.
B . In order to be able to manage each Node separately, all Node must access the NIC0 port management network.
C . the signal cable of tag "NODE01 A0-0" plugged in the Ethernet port position is A0-1, the signal cable of tag "NODE01 B3-1" plugged in the Ethernet port position is B3-0, due to the same network card two network port equivalent, can insert line dislocation, can’t be adjusted.
D . CE6350 switch connect the two stacked copper, one of failure need late replacement, because they do not affect the network interworking, you can start with the basic software measurement

Answer: ABC
