Q&A

Q Which are Huawei data center switches?

A High-performance cloud switches from the Huawei CloudEngine (CE) series are created for cutting-edge campus networks and next-generation data centers.

Q What is Huawei CloudEngine?

A Huawei CloudEngine (CE) series switches are high-performance cloud switches designed for next-generation data centers and high-end campus networks.

Q Why are Switch Ports down and faulty due to power over current?

A No faults with the switch, so we need to check the IP Phones. Power overcurrent: indicates that the current of the PD connected to the interface exceeds the maximum current of the interface.

Q What is the difference between Cisco and Huawei?

A Huawei uses only open standard protocols whereas Cisco uses a mixture of open and proprietary.
