Q: Do I need to buy power supply for S6720S-26Q-SI-24S-AC?

A: S6720S-26Q-SI-24S-AC has two power slots, by default, it configures with 1 AC power. If you need power redundancy, you need purchase additionally.

Q: Do I need to buy SFP Modules for S6720S-26Q-SI-24S-AC?

A:Yes, as S6720S-26Q-SI-24S-AC is a optical switch, the optical ports will not able to work without SFP module, if you don’t have SFP module, you will need to purchase additional SFP Module.

Q: How many slots S6720S-26Q-SI-24S-AC support?

A: It doesn't support extended slot.

Q: Can I use compatible SFP/SFP+ module on Huawei S6720 switch?

A:Yes, but the switch may generate alarm, however, it will not affect normal use

Q: Can I get technical support from if we purchase S6720S-26Q-SI-24S-AC from you?

A: Yes, has experienced technical team on Huawei switches, however, you may need to purchase technical support service from us as by default we only provide one year hardware warranty.

    I bought S6720S-26Q-SI-24S-AC from Huawei locally in previous time, I find cheaper price at, after comparing, it is brand new with sealed packing, not fake.
  2. Peru
    I received 3 units of S6720S-26Q-SI-24S-AC yesterday, packed very well. But I notice that there is S6720-26Q-SI-24S-AC, which has same ports with S6720S-26Q-SI-24S-AC. Do the 2 models have performance difference?
