DETAILS
Network demands have evolved due to requirements that include reliability, extended temperature, a high level of performance, and timely indicators when faults occur on a network. Those indicators can be as simple as an LED extinguishing on an unmanaged switch, to a Trap notification from a managed switch. As a five port switch, the ESWP205-1SFP-T offers a fiber SFP port, supporting any type of 100Mbps fiber, for Single Mode, Multi Mode and Single Strand Fiber. The switch will support any MSA-compliant SFP. The four 10/100Mbps copper ports allow Ethernet connectivity as well as PoE+ injection. LEDs support link status for the copper and SFP port as well as power and PoE+ status. The ESWGP206-2SFP-T offers the same number of copper ports, but in the speed of 10/100/1000Mbps and an additional SFP port.
A new element facing network admins is the use or availability of a power source. Power over Ethernet (PoE) is a hardware feature available on the product line of switches that can inject power into a PD (Power Draw) device. Each port is capable of not only offering Ethernet connectivity, but also PoE+ injection. PoE+ offers up to 30W of power per port, and does not interfere with the data path on the port. An 802.3at standard, it allows the end user to connect a PD device, such as a PTZ camera, to power it over the copper cabling when an available power outlet is not available. The advantage of PoE+ is that if a PD device requires less power, say 15.4W, the PoE+ port will only provide the power necessary; over-current and PD damage is not a consideration. Using a PoE+ port to provide simple Ethernet connectivity is still an option as well.
Both switches offer an extended temperature range of -40C to +85C. The extended temperature and the ability to sustain shock, vibration and freefall make this product suitable for harsh environments; it also meets IP30 rating for its metal enclosure.
WHEN COMPACT, MULTIPORT SWITCHES ARE A GOOD CHOICE
Both the unmanaged switches offer four copper ports and one or more 100Mbps SFP port for fiber connectivity. Network folks don’t always need a 24 or 48 port switch, and a 5 or 8 port switch can be a cost-effective solution. Offering Power over Ethernet and redundant VDC power inputs, the 5 port ESWP25-1SFP-T is an unmanaged switch, with plug and play copper ports and a fiber port for ease of installation. Each copper port supports PoE+, and no user intervention is necessary for providing the required amount of power to a device. The ESWGP206-2SFP-T offers more flexibility on the SFP ports, as Port #5 can support gigabit copper or fiber SFPs, while Port #6 supports strictly fiber SFPs.
