GS510TLP and AGM731F SFP Module - NO LINK to TP-Link T2600G-52TS

[woodgee]

Hello,

i have an new GS510TLP 8-Port POE Switch with 2x AGM731F SFP Modules.

The Swich have the latest Firmware 7.0.0.20 installed.

When i connnect the GS510TLP over the AGM731F SFP Modules with the TP-Link T2600G-52TS SFP Modules, i get no Link on the GS510TLP. The T2600G-52TS shows me the Link is UP.

How can i solve this problem ??

I have tried to switch off "auto-negotiation" on both switches, in the TP-Link GUI i can it switch off, but in the Netgear GUI can´t.

TP-Link Module TL-SM311LM

Netgear Module AGM731F

LWL Duplex OM2 (Multimode, 50/125) - 0,5m

Have a spare fiber patch cable at hand to test?

Hello schumaku,

i have tested the connection with a different cable (same type), but there is no difference,

the tp-link switch shows me an link on the sfp module (led indicator and web interface).

the Netgear shows me no link on the sfp module (led indicator and web interface).

i have tested both sfp ports on the netgear (port 9 and port 10) with different sfp modules and

i have tested two different sfp ports on the tp-link, with different sfp modules -> NO LINK ON THE NETGEAR SWITCH

so i think there is no faulty sfp module and no faulty cable.

it must be something else, maybe the firmware on the Netgear switch?

bad initial handshake?

There is no autonegotiation on SFP/SFP+ ports and fiber links - that's why I think Netgear is right not to show this control.

Get in touch with the Netgear support via https://my.netgear.com/

Today I have checked the following things:

tp-link switch via sfp to tp-link switch sfp -> works link is up and data pass the link

tp-link switch via sfp to unifi switch sfp -> works, link is up and data pass the link

tp-link switch via sfp to netgear switch sfp -> no link

unifi switch via sfp to netgear switch sfp -> no link

netgear switch sfp port 9 to netgear switch sfp port 10 -> link is up (led indicates the link and webinterface shows the link up)

-> there must be an problem with the netgear switch, i think an firmware problem ??
