The Stack setup of CloudEngine series switches just requires ordinary service cables instead of dedicated stack cables. Optical ports can be connected using high-speed cables, AOC cables, or optical modules+fibers. Electrical ports can be connected using Category 6A or Category 7 cables.
When setting up a stack, ensure that the optical modules and cables on the ports used for stack connections are properly installed and these ports are Up.
Note:
10GE optical ports can be used for stack connections only when they have 10GE optical modules installed. They cannot be used for stack connections when having GE optical modules or GE copper modules installed.
SIP ports on the CE12800 and CE12800E can use network cables or LC fibers. When LC fibers are used, the SIP ports must have GE optical modules installed.
