The S series fixed Ethernet switches integrate the access and transmission functions to provide reliable access/aggregation and high-quality transmission of services on enterprise networks. The switches are built on an integrated hardware platform, and their hardware system consists of the chassis, power module, fan module, extended cards, and Switch Control Unit (SCU).
The S series fixed Ethernet switches are available in a variety of models for you to choose based on your network requirements.
S6700 Series Switches Characteristics The S6700 series Ethernet switches are next-generation 10G fixed switches. The S6700 can function as a core switch on a campus network. The S6700 has industry-leading performance and provides line-speed 10GE access ports and line-speed 40GE even 100GE uplink ports. It can function as a core switch on a campus network to provide 40 Gbit/s even 100 Gbit/s traffic aggregation.
S6720S-26Q-EI-24S-AC FAQ
Q1: What is the AC power supply range of this switch? Can it be used in overseas data centers (110V)?
A1: It supports AC 100-240V wide voltage power supply, requiring no additional transformer configuration. It can be used directly in overseas 110V data centers, offering maximum cross-border deployment compatibility.
Q2: When connecting 24 10GE ports to GE speed devices, is manual configuration or automatic adaptation required?
A2: Automatic adaptation is supported! No manual parameter adjustment is needed. After inserting a GE optical module or connecting to an Ethernet device via an opto-converter, the ports automatically switch to GE speed, improving adaptation efficiency by 80%.
Q3: What are the core differences between this and the DC power supply version (S6720S-26Q-EI-24S-DC)? How to choose?
A3: The core difference lies in the power supply type: the AC version is suitable for ordinary enterprise/campus data centers (with stable AC power supply); the DC version is suitable for industrial/base station data centers (without AC power supply). For most office and park scenarios, choose the AC version; for scenarios without AC power supply, choose the DC version. The ports and performance are completely identical.
