Pay attention to total 65W available and max speed rate 100Mbpsfunkey_monkey wrote: »Is this decent POE+ switch?
Looking for a low budget POE+ switch with at least 8 ports.
https://www.scan.co.uk/products/9-port-tp-link-tl-sf1009p-desktop-switch-9x-10-100mbps-8-poeplus-ports-ieee-8023af-at-65-w-poe-budge
The arrangement on this one suits my Comms cupboard as the Cat5e cables come down in from the ceiling. I could then have box facing downwards, means the cables just connect into the top facing side and the I can look up into the cupboard and see the status lights.
Thanks.
Theoretically you can have 8 devices under 8W each simultaneously
https://www.tp-link.com/uk/business-networking/poe-switch/tl-sf1009p/When total power consumption exceeds 65 W, the intelligent power management will cut the lower priority port power.

Its probably OK for some applications.funkey_monkey wrote: »So not a great one then?
You might need to approach this from other side:- many PoE devices you will run
- What power is required per device specs
- Poe protocols supported per device
- Ethernet cable distance ant type Cat5 vs Cat6....
As sample take reolink B800. By specs it require 8W, LAN interface 100Mbps
From here, if you would have 8 of them cameras, you'd be just within max limit. Theoretically should work

There is no direct way to monitor traffic through the consumer grade switch, luxury of managed switches. At least I'm not aware.funkey_monkey wrote: »Any recommendations for a decent one then?
Current one is SMC EZ Switch SMCFS801 which has 8 x 10/100.
How can I check if it is strangling network performance?
TP-Link or Netgear are good. if you really need 8 PoE ports it'll cost bit more for a gig
I believe you already seen 8port x4PoE on Amazon if that suffice.
I thought Ubi AP's are shipped with power injectors.

I think that line state what is "in the box", however, PoE standard to be checked - switch has to support both or 802.3afhttps://www.senetic.ie/product-uap-ac-lite/
Is this the AP you are using?
I don't think it will work with a POE switch.
It says passive POE so 1000mbs won't be possible as it uses 2 pair for power only.
Also 24V and POE+ switch is over 48V
https://help.ui.com/hc/en-us/articles/115000263008#3 see ** note
Ubi offers PoE switch bundled with AP https://www.amazon.co.uk/Ubiquiti-Networks-UAP-AC-LITE-Access-Point/dp/B08GQZX7PW/ref=sr_1_1?dchild=1&keywords=UAP-AC-LITE&qid=1606823841&s=computers&sr=1-1&th=1

Datasheet says it can be powered by a Ubiquiti UniFi switch. Diagram shows an Ubiquiti US-16-150W UniFi switch - which is POE+.
The only feature I didn't pick up on was:
"Supports POE+ IEEE 802.3at/af and 24V Passive PoE"
The TP-Link supports both at and af
First Netgear has both af & at.
The second Netgear has af.
Looks good so.
I looked at the older model first which was passive only. Carry on

LED's good for basic troubleshooting, but you wont be looking at them all time.funkey_monkey wrote: »Any recommendations between the TP-Link TL-SG1210P and the Netgear GS310TP?
I have seen a YuanLey 8 port POE+ switch with 120W budget and af/at protocols. However, I've read a review which states that these might be white good branded to the company and might have a tendency to drop to 100Mbps.
https://mightygadget.co.uk/yuanley-8-port-gigabit-120w-poe-switch-review/
All 3 get a mention here:

I think it is really between the TP-Link and the Netgear. From my perspective - the main advantage of the TP-Link is that it can be oriented easily into the electrical cupboard to match the device it is replacing - i.e. wall mounted above head height with cables entering at top so display downwards so easily visible.
With the netgear I'd have to mount the switch with sockets facing right and cable coming down from above and then turn at 90deg into the switch - if I want visibility of the LEDs.
Apart from that I've no real opinion on them.
Would they all have internal or external PSU?
If avail, mount switch up higher ports facing down and loop cables 180°. Bit of DIY - make 10-15mm gap between case and wall - you would be able to route cables beneath box.
Proper way would be to install patch panel. Variant with keystones eliminates need of punching.
TP/NetG above switches have external power supp. lookup images online

It strike me that you might misinterpret 802.3af requirement.funkey_monkey wrote: »Grand - I've a few ideas for tidying the cables.
Looks like the Netgear would be the best choice then.
802.3at (PoE+) is later version of a standard, with expanded capabilities re power supply(higher wattage)
By definition it is backwards compatible with 802.3af
Power parameters are determined by negotiation process defined by this standard. Any device that is certified to 802.3aX standard it will proceed with negotiation.
So if switch is rated PoE+ it will provide to device that only require 802.3af
It will/might not work if device is rated to PoE+ , but switch is only 8023af

Way to go! Two SFP's, fiber up-link !funkey_monkey wrote: »It should be arriving early next week so I'll check it then and see what happens.
It has both af and at:
If interested, you could get SFP-to-RJ45 adapter - extra port for up-link, no waste of PoE ports

I'll see how I go. Trying to figure out how to tidy up the comms cupboard at the minute. It is a bit of a hash with cables everywhere.
The shotgun sat cable is a bit of a mess, but not sure what I can do about it.0 -

Should have either holes for screws to hung in or holes for wall-mount bracketfunkey_monkey wrote: »Arrived today and doesn't look to be wall mountable.

I contacted the seller and they confirmed it was an error in the description. Sending it back and got £5 goodwill from them :pac:0 -
And the TP-Link is here!
With mounting holes in the base
Would have been nice if they considered that the user might want to wall mount the transformer too :rolleyes:
Not sure how I'm going to wall mount it - suggestions?
Which uplink do I put my router into?- Uplink 1 is a SFP port and works with a 1000Mbps SFP module.
- Uplink 2 is a RJ45 port.

SFP require additional plug.
According specs, both 1000

you will be limiting your network to 100Mbps with this switch
