Teach you how to identify the type and version of a box switch

A few days do not see, hear the people in the rivers and lakes of the small partners of the little editor is miss, this is not a small editor to show up for everyone to puzzle out. A small series of buddies introduced cartridge switch all series, so many series, each series has little more than several dozens of models, is a headache how to distinguish the differences, how to choose to type? Not urgent, the following small editor to answer one by one.

Knowledge point 1: do you know how the box switch is selected, which is the two layer switch, and which is the three layer switch?

All S1700 models are two switches, different models and fast downlink downlink sub Gigabit (model name with G said downlink port Gigabit, such as S1700-52GFR-4P-AC; no G for the downlink of megabytes).

All S2700 models are fast down the two layer switch.

All S3700 models are fast down the three layer switch.

In S5700, S5700-LI series, S5700S-LI series and S5710-LI series are downlink Gigabit two level switches (as long as the LI in the name is two tier), and the rest of the series are downlink Gigabit three level switches.

S6700 is a full million Zhao San layer switch.

Knowledge point 2: do you know the role of the card card, which type of switch is to support the card, and how to identify it?

When the inherent interface on the switch does not meet the needs of the partners, a specific type of card can be selected. The card is generally selected, mainly providing a number of more rich functions and applications, such as a more high-speed uplink interface, a special stack card stacking function, and so on.

Switch series

Whether the card is supported

S1700

won't support

S2700

won't support

S3700

Only HI series support

S5700

With the exception of the S5700-LI series, the S5700S-LI series, and the S5700-26X-SI-12S-AC model, the rest of the model supports

S6700

won't support

Tell the guys a quick way to identify them: if the name of the model is C, it means the model support card, such as S5700-28C-EI.

A few special items: the S5700-24TP, S5700-48TP name in the S5700-SI series does not have a C, does not support a business socket card, but supports stacked inserts.

Knowledge point 3: do you know which switch models support PoE power supply and how many interfaces can you support at most?

The name of the switch model with the word "PWR" indicates that this model supports PoE power supply, such as S5710-52C-PWR-EI.

Switch is supplied by PoE through PD interface. All PoE switches support two standards, 802.3af and 802.3at. 802.3af standard supports the maximum 15.4W power supply per port. 802.3at standard supports the maximum 30W power supply per port. The corresponding standard is determined by the use of PD, and the switch can be adaptable.

Each PoE switch can support many interface to provide the corresponding power module, PoE power supply and the use of standard equipment, the limitation of the relationship, here Xiaobian friends only for the maximum number of interface are given each series can support to the theory, if the buddies think solution to the specific model can view the corresponding products the "manual" hardware description.

Switch series

Maximum PoE power supply interface number (802.3af standard) supported

Maximum PoE power supply interface number (802.3at standard) supported

S1700

Do not support PoE power supply

S2700

8/16/24/48 individual

4/8/12/24 individual

S3700

8/16/24/48 individual

4/8/12/24 individual

S5700

8/12/16/24/48 individual

4/6/8/12/24/26/48 individual

S6700

Do not support PoE power supply

Knowledge point 4: do you know what version of the switch is out of the switch? What is the matching relationship with the model?

HUAWEI box switch is divided into two different software versions according to SMB switch (S1700) and non SMB switch (S2700/3700/5700/6700), and there is no correlation between the two sets of software versions.

A map and a table are used to list the evolution of the software version of the series of switches and the matching relationship between the version and the model.

The three software versions of S1700:S1700 are independent and cannot be promoted or degraded between each other. For example, devices supported by V1R6C00 cannot be upgraded to V1R7C00.

S2700/3700/5700/6700: the matching relationship between different models and versions is different. See the following table in detail. The same model can be upgraded and degraded between the supported software versions.
