How do I determine the optical modules and cables supported by a card or switch

Run the display transceiver command on a switch. If the following information is displayed, the optical module can be identified by the switch. This command can also display the type, wavelength, transmission distance, and power of the optical module. NOTICE: The switch must have Huawei certified optical modules installed. Non-Huawei-certified optical modules cannot ensure transmission reliability and may affect service stability on the switch. Huawei is not responsible for any problem caused by non-Huawei-certified optical modules and will not fix such problems.

Yes. Ports on a CE-L24XS-EC card support GE optical modules. A CE-L24XS-EC card provides packet processing and traffic management on twenty-four 10GE optical ports. - When the 10GE ports work in 10GE mode, they support SFP+ 10GBASE-SR/LR/ER/ZR/LRM/USR optical modules, and can work with 10GE Twinax copper cables or AOC cables. - When the 10GE ports work in GE mode, they support SFP 1000BASE-X optical modules and 1000BASE-T copper modules. When using a 1000BASE-T copper module, a port supports 10M/100M/1000M auto-sensing.

CE6810 switches are stacked through 40GE QSFP+ high-speed cables. The number of cables varies with the number of the OceanStor 9000 nodes. CONFIGURE principles are as follows: - Configure two cables if a cluster contains 3 to 16 nodes. - Configure three cables if a cluster contains 17 to 24 nodes. - Configure four cables if a cluster contains 25 to 31 nodes. If the number of cluster nodes is greater than or equal to 32, use CE12800 switches instead of CE6810.
