The new D-Link DSS-100E-18P switch is a device not manageable, this means that we will not have a management web interface where to configure VLANs, Link Aggregation, Spanning-Tree Protocol or other typical L2 functionalities, however, we do have a physical switch that will allow us to configure a total of three very interesting functionalities, which we will explain later.
This unmanageable switch has a total of 16 Fast-Ethernet ports (10 / 100Mbps) with PoE and PoE +, that is, it is compatible with the 802.3af / at standards to provide up to 30W of power per port. Thanks to the fact that it has a 230W Power Budget, we will be able to power a large number of IP cameras through its 16 PoE ports. We also have one dedicated Gigabit Ethernet port to do uplink tasks, and we even have One Gigabit Ethernet RJ-45 / SFP Combo port. Thanks to these two Gigabit Ethernet ports, we can connect this switch in a trunk way to the network, and not have a bottleneck.
This model has a 7.2Gbps switching capacity in total, the maximum forwarding speed is 5.36Mpps, uses the store-and-forward method to forward the frames, allows a MAC address capacity up to 4K addressesFurthermore, how could it be otherwise, we have auto negotiation on all ports and auto MDI / MDIX. A very important feature of this model is its physical switch that activates different options: Standard, Isolation, Long Range.
- Standard: In this configuration mode, ports 1-16 can communicate with each other smoothly, the sync speed is 10 / 100Mbps.
- Isolate– In this configuration mode, ports 1-16 are isolated from each other, but they can all communicate with ports 17 and 18 (the Gigabit Ethernet ports) which are the trunk ports.
- Extend: In this configuration mode, ports 1-16 communicate with each other, but ports 8-16 will synchronize at a speed of 10Mbps to reach up to 250 meters away and power different devices.
Regarding the dimensions of this switch, we must bear in mind that it is a professional and rackable equipment. The dimensions are 44cm wide, 18cm deep and 4.4cm high, the weight is 2.1Kg. The consumption of this equipment depends on the number of equipment that we power by PoE, in standby it is 10W, and at maximum performance with all PoE ports working, the consumption is 265W maximum. Finally, it incorporates a fan to evacuate the hot air from the interior, something normal in a switch with so many PoE + ports, however, this fan is heard very little, ideal so that it does not make too much noise.
Although this D-Link DSS-100E-18P switch is capable of reaching a distance of up to 250 meters, if you need to go further, the manufacturer D-Link also has a PoE extender that will allow us to increase this distance to 650 meters maximum. The D-Link PoE extender is called DPE-302GE and it allows us to extend the maximum distance by 100 meters, if you need to reach more than 250 meters plus 100 meters of this extender, you can buy more extenders up to a total of four extenders, following this scheme:
As you can see, we will reach a distance of up to 650 meters maximum to feed IP cameras, logically, the maximum speed will be 10Mbps, enough for the bitrate of the cameras that is usually lower, even if they are Full HD.
Unboxing and first impressions
In RedesZone we already have with us this new non-manageable switch oriented to video surveillance, to power IP cameras at a distance of up to 250 meters at speeds of 10Mbps in its ports. This switch model is ideal for those environments where we have to cover a long distance with the network cabling to be able to power the IP cameras, since, due to the circumstances of the scenario, it is not enough only with 100-meter segments, which is the standard. . In addition, we must bear in mind that we can extend these 250 meters with the “extenders” that we have taught you before. Below, you can see in detail our video with the unboxing and first impressions:
Soon in RedesZone you will be able to see a complete analysis of this unmanageable switch for video surveillance, so you can see the real performance it provides us.
