Mount

The form factor determines how the switch is installed.

Desktop. Devices designed to be placed on a flat surface such as a countertop or shelf; some models also allow hanging on the wall. Significantly easier to install than rack or DIN rail equipment (see below), but most desktop switches are entry-level, maximum mid-range. This is because desktop placement is less secure than rack or rail mounting, making it less suitable for professional equipment.

Rack mounted. Switches designed for installation in a telecommunications rack. To do this, the design provides for an appropriate set of fasteners, and the body is made in a standard size. This size is quite large, which allows for numerous network ports; and the rack mounting itself is reliable. Therefore, this option is used by most professional-level switches, although there are also relatively simple models with this installation method.

Mounted on a DIN rail. Switches mounted on a standard DIN rail. Such rails are used as mounting fixtures, in particular, on electrical panels and in cabinets for special equipment, however, if desired, they can be fixed to any vertical surface, including a regular wall. Specifically, "switches" with a similar installation, as well as rack-mounted ones, are mainly of a professional level; however, rail-mounted models are much smaller, resulting in more m...odest functionality and fewer ports. Also note that they are usually executed in a vertical rather than a horizontal layout.

Street (on the mast). Switches that can be installed outdoors. A characteristic feature of such equipment is the enhanced protection of the case, which protects the internal components from dust, moisture, high and low temperatures, etc. winter application (if you need a frost-resistant model, you can use the "Operating temperature" list below). However, if the equipment needs to be placed on the street (or in a room where the conditions are not very different from the street ones), then it is definitely worth choosing from this category.

Uplink

The number of Uplink connectors provided in the design of the switch.

“Uplink” in this case is not a type, but a connector specialization: this is the name of the network interface through which the switch (and network devices connected to it) communicate with external networks (including the Internet) or network segments. In other words, this is a kind of "gate" through which all traffic from the network segment served by the switch is transmitted further. Uplink, in particular, can be used to connect to a similar "switch" (for horizontal network expansion) or to a higher level device (like a core switch).

Accordingly, the number of Uplink connectors is the maximum number of external connections that the switch can provide without using additional equipment. The specific type of such a connector may be different, but this is usually one of the varieties of LAN or SFP; see "Uplink type" for details.

Uplink type

The type of connector(s) used as the Uplink interface on the switch.

For more information about such an interface, see above; Here we note that the same network ports are usually used as Uplink as for connecting individual devices to the switch. Here are the main options for such connectors:

— Fast Ethernet — LAN network connector (for twisted pair cables) supporting speeds up to 100 Mbit/s. This speed is considered low by modern standards, while the Uplink port places increased demands on throughput - after all, traffic from all devices served by the switch passes through it. Therefore, in this role, Fast Ethernet ports are used mainly in inexpensive and outdated models.

— Gigabit Ethernet — LAN connector supporting speeds up to 1 Gbit/s. This speed is often sufficient even for a fairly extensive network, while the connectors themselves are relatively inexpensive.

— 2.5 Gigabit Ethernet — LAN connector supporting speeds up to 2.5 Gbit/s.

— 10Gigabit Ethernet — LAN connector supporting speeds up to 10 Gbit/s. Such features allow you to work comfortably even with very large volumes of traffic, but they significantly affect the price of the switch. Therefore, this option is rare, mainly in high-end models.

— SFP. A connector for a fiber optic cable that supports speeds of about 1 Gbit/s. At the same time, over Gigabit Ethernet, which has a similar throughput, this connector has one noticeable advantage - a...longer connection range (usually up to 550 m).

- SFP+. Development of the SFP standard described above. Switches usually provide a connection speed of 10 Gbit/s; like the original standard, it noticeably exceeds the effective range of an Ethernet connection. On the other hand, the real need for such speeds does not arise so often, and SFP+ is quite expensive. Therefore, the presence of such Uplink connectors is typical mainly for high-end models with a large number of ports.

- SFP28. Another development of SFP with increased throughput up to 25 Gbit/s.

- QSFP / QSFP+. The fastest SFPs up to 40 Gbit/s.

Note also that the connectors described above (except perhaps Fast Ethernet) are rarely used as the only type of Uplink input. Combinations of electrical and fiber optic ports—SFP/Gigabit Ethernet and SFP+/10Gigabit Ethernet—have become noticeably more widespread. This provides versatility in connection, allowing you to use the most convenient type of cable in a given situation; and if necessary, of course, you can use all Uplink inputs at once. However, it is worth considering that in some models, Ethernet and SFP interfaces can be combined in one physical connector. So before purchasing, it doesn’t hurt to clarify this nuance separately.

There are also switches that use a combination of two types of SFP - SFP/SFP+; however, there are few such models and they are mainly of the professional level.

PoE (output)

The switch supports the Power over Ethernet function.

This feature allows the switch to supply power to network devices over the same Ethernet cable that transmits data. This reduces the number of wires and simplifies power supply, which is especially convenient if the device is installed in a hard-to-reach place where there is no outlet nearby, and it is difficult to pull an additional cable. An example is an IP surveillance camera installed under the ceiling.

The number of PoE outputs may vary. It should also be borne in mind that when several consumers are connected at the same time, specific power restrictions apply; see "Total PoE Power" for details.

Accordingly, such devices are much more expensive than switches without PoE.

PoE outputs

The number of PoE-enabled outputs (see above) provided in the design of the switch. This number corresponds to the maximum number of PoE network devices that can be connected to this model at the same time.

PoE output power

The PoE power (see above) provided by the switch to each individual PoE output. This indicator allows you to evaluate whether a particular device can be connected to such an output — the power consumption of the load in peak mode should not exceed the output power of the port. There are three standards EEE 802.3af ( PoE, ~15W), IEEE 802.3at ( PoE+, ~30W) and IEEE 802.3bt ( PoE++, ≥40W)

Note that when connecting several PoE devices at the same time, the total PoE power must also be taken into account — see below for more details.

Total PoE power

The total output power provided by the switch when powering devices using the PoE standard (see above).

This indicator usually corresponds to the sum of the powers of all outputs — that is, the power of one PoE port, multiplied by their total number. However, the power limits for one output and for the entire switch are somewhat different: if a load with a power equal to the output power of the power supply on this connector can be connected to a single connector, then the total power consumption of all devices connected via PoE should ideally not exceed 75% of the total power supply — this gives an additional guarantee in case of malfunctions. In fact, this means that all PoE outputs cannot be used “to the fullest” at the same time. For example, if there are two such outputs, and one is loaded at 100%, then the second can be loaded with a maximum of 50% — the total power consumption in this case will be the same 75% of the total output. Therefore, a large total power is needed when using the device to the maximum.

PSU

— Built-in. The built-in power supply does not take up space on the outside, but can significantly increase the size and weight of the entire switch. Because of this, this option is quite rare — mainly among rack-mount models (see "Form factor"), where an external unit can create significant inconvenience, as well as among the most powerful desktop switches, for which restrictions on dimensions and weight is not critical.

— External. Theoretically , an external power supply requires additional space, and therefore is not as convenient as an internal one. In fact, most blocks of this type are quite compact in size and are equipped with “plugs” for sockets right on the case — in other words, the block is installed on a socket, and from there the wire stretches to the switch. And the absence of power circuits and transformers inside the case has a positive effect on compactness. Thanks to all this, this option is very popular among desktop models (see "Form factor"), primarily entry-level and mid-level.

— No BP. The absence of a power supply both in the design and in the delivery set is a rather rare case found in three types of switches. The first variety is models that use PoE power (see above) and do not require separate power sources. PoE power is relatively small, so relatively simple devices with a small number of ports fall into this category. The second variety is professional switc...hes, the power supplies for which are sold as separately installed internal modules; such equipment may even provide the possibility of using two PSUs simultaneously (main and backup) and hot-swapping them. The third type — switches with installation on a DIN rail (see "Form factor") and having terminals for connecting a specialized external power source.
