Model: SG2005P-PD  
Hardware Version: V1
Firmware Version: 1.0.6 Build 20241205 Rel.64944

This is a device added to an OC200 v1.0 with firmware version 1.32.6 Build 20241101 Rel.41525

The SG2005P-PD is powered by TL-POE170S and is connected to an SG2008P v3.20

 

I'm wondering if anyone else is experiencing the same as my issue. Additional info, the PoE Port5 is configured as trunk while the rest Ports1-4 are configured as VLAN50. Currently only Port1 is configured with Power Delivery because Max PoE has been lighting up previously. On Port1 I have a Dahua PTZ Camera which takes about 12.9W of Power. Port2 is another PTZ Camera which now draws power from an external source. It says that there is still 70.68% Remaining PoE Power. Please see the attached screenshots.

 

My problem is when I reboot my SG2005P-PD with one or both PTZ Cameras plug on Ports 1 and/or 2 the switch won't boot up and remains without power. TL-POE170S also doesn't show that power is being delivered (PoE LED isn't lit). If I unplug the PTZ cameras and do a power cycle either by rebooting the TL-POE170S or unplugging then plugging the LAN cable on Port5 the switch will boot up. Once it has booted up I can plug back the PTZ cameras and both will work normally. Even if both PTZ cameras are drawing power from SG2005P-PD the Remaining PoE Power is still above 50%. I have tried doing a Forget and re-Adapt the SG2005P-PD twice and still the same results. I have also tried replacing cables, bringing the TL-POE170S very close to the SG2005P-PD by using shorter cable but the problem persists.

 

This is unacceptable especially during power outages. Has anyone seen this issue? Am I missing anything like configurations or firmware?

 

Thanks in advance to those who will share their solutions.

Hi @CarloPH,

 

I think the SG2005P-PD might be underpowered... The SG2008P powering it is POE+ which is max 30W per port and the SG2005P-PD's budget is (according to documenttion) is just 19W and not the 31.10W shown in the UI when powered vi POE+ (802.3at).  I assume it's a bug because the POE out budget on the SG2005P-PD should be lower than the POE+ maximum output from the SG2008P.  That said, the 12W device is below the 19W documented power budget.  What we don't know is if the SG2005P-PD is getting the full 30W from the SG2008P.  Try powering the SG2005P-PD with a POE+ injector and see if the issue persists.  Also verify that the cable lenth is also under 328ft as that could also cause power issues.  If you don't have an injector, unplug all other POE devices from the SG2008P and test.

  @D-C thanks for your response.

 

But i think you might have missed two key points here namely,

 

1. The SG2005P-PD is powered by TL-POE170S and not by SG2008P.

2. I did make sure that the cables are shorter than the prescribed length in fact i mentioned that i even tried replacing the cables with a much more shorter ones just to verify if it was a cable issue.

 

Anything else that i need to check?

Sorry @CarloPH, I did indeed miss those details. 🤦‍♂️Could the TL-POE170S be bad?  Does the SG2008P have 30W surplus to power the SG2005P-PD with one camera and bypass the TL-POE170S for a test?  Any other options to test without using the TL-POE170S?

  @D-C thanks again for your follow-up response.

 

This has been deployed already. I will be only be able to test it later this week. Will keep you posted on the results.

Shorten the cable. Use a 3ft and test it with the POE170S. This 170S is recommened for this switch. It should be working fine. Update us once you have something new.

It's not deleted @CarloPH.  I think one or more of the forum hosting servers are sick.  If you refresh the page like 10 times or more it will eventually hit a healthy host.  Same thing with posting, if it fails re-submit until it works.  I'm guessing the forum server support team must all be on holiday.

By changing the cable to a shorter one, do you mean that you have tried short cables on both ends, POE170S to the SG2005P-PD as well as the SG2005P-PD to the camera?

Yes. Tried all scenarios in changing cables with the same results. Verified that the cables used are up to standards as well.
