Engineer Installed a Customer Unit for OceanStor 9000 Equipment Installation

Engineer installed a customer unit for OceanStor 9000 equipment installation (a total of 5 OceanStor 9000 C Node, front and rear ends are 10GE TOE networking, on-site installation TOE network card) . Then connected the signal lines, power lines, and debugged the software. In the period of project tension, the hardware installation process has some of the following phenomena. Which of the following description of these phenomena is correct? (Multiple choice.)

A) 5 devices TOE NIC A0, B1, and A0, B3 have these two ways, as are inserted in the PCIe slot, will not affect the system. Deployment will not affect the network bandwidth, so it cannot be adjusted.
B) The signal cables are long and need to be strapped to the cabinet or placed on the bottom tray.
C) Label NODE 01 A0-0 The signal cable is inserted in the network port A0-1. The signal cable labeled NODE01 B3-1 is inserted in the network position B3-0, due to the same network card two network port peer, you can place the wrong line, you cannot adjust.
D) CE6850 switch connected to two stacked copper cables, one of which is needed to post-cold more cold, because it does not affect the network interoperability. You can base this software debugging.
