HPE Instant On Aruba 1930 8G Class4 PoE 2SFP Switch
The Aruba Instant On 1930 8G 2SFP 124W (JL681A) is a fairly affordable 8G Class4 PoE 2SFP 124W switch. The name is bulkier than my car with attached two-axle trailer and 2 tons of squared timber, but it actually already contains everything you need in terms of information. The parts are managed fixed-configuration Gigabit switches that are easy to deploy and still affordable. The balancing act between simple equipment for well under 100 Euros and professional devices in the high-price segment is quite good here, because the up to 124 watts for PoE are a small house number and usually completely sufficient. Thankfully, the switch is also passive, so no dodgy propeller crew is annoying.
The innocent white of the case is perforated for that very reason, and airflow shouldn’t be a problem as long as you stick to the rules of the domestic ventilation game. Therefore, you should be careful to leave the switch airy in the room and not build anything up, especially on the side near the power supply. Otherwise, many PoE blackheads will eventually die of heat exhaustion. The brackets and screws included in the accessories at least help with professional installation at lofty heights. If you like it more down to earth, you can use the small rubber feet that can be stuck on.
A total of 8 RJ-45 PoE ports with auto-sensing (10/100/1000 class 4) and two 2 SFP 1GbE ports can be found on the front, as well as all the status LED, mode switcher and reset button behind the small hole. The power plug is then logically at the back.
What is there to write about a plug & play device? The switch offers intelligently managed Layer 2+ Ethernet (I’ve long disliked the inflationary use of “smart” as a buzzword) complete with VLANs and link aggregation, as well as advanced features like static Layer 3 IPv4 routing, ACLs, spanning tree protocols, and IPv6 host mode. There’s also PoE for powering APs and IoT devices, various security controls, and a pretty convenient mobile app.
The Aruba Instant On mobile app can then be used to set up, manage and monitor the on switch(es) and access point(s) directly from the phone. Cloud-based access can thus be used to access the network at any time and from anywhere. It’s convenient, a matter of conscience, but not for real high-security areas. However, this is not a hurdle for the normal user. According to Aruba, Instant On automatically manages all participating devices and applies the highest (critical) PoE priority to Instant On access points to ensure uninterrupted power and wireless network access. Wired and wireless voice traffic is prioritized end-to-end with high QoS priority to ensure optimal voice performance, according to vendor marketing. It is difficult to test this here with my resources, but I have at least mentioned it once.
Otherwise, I’d better stop listing the features and refer to the spec sheet, which can do that better:
