Good day. You may find an answer to your question here https://community.netgear.com/t5/Plus-and-Smart-Switches-Forum/GS105PE-VLAN-trunking-not-working/m-p/2199583#M20458. Otherwise, it is best to contact the manufacturer's support.
Hello,
It depends on which switch or which POE feed you use. In general, I recommend connecting max. 1 pure POE switch per POE port of the router, otherwise no further POE devices can be connected to the switch. If no other POE devices are connected to the switch, at least two other POE switches can be connected, but I could not try out more.
The question is what is meant by "salt.box". This switch can be configured so that multicast queries are not routed to all ports. I can't say whether Salt uses multicast for TV like Swisscom. But in any case the switch would be compatible with the TV setup box.
If "salt.box" means the CPE, then this will work, but only with 1gByte/s. Salt offers 10gByte/s. Salt offers 10gByte/s. But there are hardly any 10 Gbyte/s switches anyway.
found in the ratings for this switch:
Practical concept: A PoE connection from a suitable uplink switch feeds this small switch, which can itself supply two other devices with PoE.
Ich war etwas voreilig mit meiner Frage... Hier gleich die Antwort selbst: Nein!

Can it be powered by an external power adaptor?
No, it can only be powered by a PSE .
It may, given that the MR18 consumes 9.8W and theoretically 19Watts are provided via PoE passthrough according to the datasheet:
http://www.downloads.netgear.com/files/GDC/datasheet/en/ProSAFE_Web_Managed_Switches_DS.pdf
Having said that, the device itself needs to be powered via a PoE+ (802.3at) port otherwise only 7.9W will be provided to the PoE enabled ports which is probably not enough.
I use a Trendnet TPE-115GI.
Any PoE+ or 802.3at injector/switch should work.
PoE / 802.3af is not sufficient if other PoE devices are also to be supplied via the GS105PE switch.
Netgear even offers a lifetime warranty on all products in the ProSAFE range. For technical reasons, this cannot be displayed correctly on our website at the moment. You can find more detailed information here: http://www.netgear.de/business/documents/prosafe-lifetime-warranty/default.aspx
> Unfortunately, only the yellow light (=> 802.3af) and not the green light (=> 802.3at) is lit on the switch,
I assume we are talking about the right-hand LED on port 5 - and not the left-hand LED which indicates the negotiated current speed on the ethernet connection.
> although this PoE injector should be 30W. Can someone explain to me why this is so?
802.11af/802.11at etc. performs a rather complex handshake when the link is powered up (plug in the cable, switch on, etc. ) - although there are also several legacy variants of this. This process regulates how much power is made available at the PSE (Power Sourcing Equipment) and how much power is available and can be drawn at the PD (Powered Device). Unfortunately, the fact that the switch is supposed to support both variants does not make it any easier.
> Is the injector supplying too little power? Is the switch defective?
Probably neither. As @Final has already pointed out, this is probably a compatibility problem, which typically leads to problems with more or less good injectors. Switches with built-in IEEE-compliant PoE/PoE+ and higher power levels usually work perfectly with the GS105PE.
The effective problem is that if the switch only displays an 802.11af power supply, only a single Class 1 or Class 2 (no Class 0!) PD can be operated. https://kb.netgear.com/25541/GS105PE-PoE-troubleshooting
Since we don't know which firmware is installed in the box, there may be an additional hurdle to the recommended update. Possibly the bootloader (which contains a lot more that is relevant for PoE problems) has to be updated - but the latest firmware kits do not contain this bootloader. Maybe we'd better have a look at https://community.netgear.com/t5/Smart-Plus-and-Smart-Pro-Managed/bd-p/business-smart-plus-click-switches - there the paths are a bit easier.
I would install a mesh router system to get a very stable WLAN signal in the entire flat or house. This set, called AX3000, is very inexpensive and consists of two identical WLAN mesh routers, each of which contains a 3-fold Gbit switch and an additional WAN interface. One of them is then placed next to the router of the Internet provider and receives the Internet connection from it via the WAN connection. The WLAN at the Internet provider repeater is switched off and the mesh system takes over.
Xiaomi Mesh System AX3000 (2-Pack)
The system is very powerful and can manage up to 256 devices. Up to 10 mesh repeaters can be networked with each other.
Somehow some models and data are mixed up - I assume you are talking about the GS105PE. In any case, the maximum power consumption is always specified including the maximum available PoE power.
GS105PE: Power Consumption (when all ports used, line-rate traffic and max PoE) - Worst case, all ports used, line-rate traffic, max PoE (W)
traffic, max PoE (W): 22.0 W. [1]
The rather academic PoE budget on the GS105PE encloses: "PoE pass-thru: 19W with 802.3at/7.9W with 802.3af input power" [2].
On the GS105PE, the available power also depends on the PoE power supply. With IEEE 802.3af just under 6.5 W are available at the connected PoE device, with IEEE 802.3at either once just under 13W or twice just under 6.5 W at the PD (Powered Device). At the switch this is 16.4 W or twice 7.2 W (line loss over 100 metres says hello). [3]
The switch requires 22 W - 19 W == 3 W under full switch power and the maximum cable lengths in pure GbE operation without PoE - this corresponds roughly to a 5 port GbE switch such as the GS105Ev2 [1].
