My fibre internet provider requires that I use their transceiver (a Huawei SmartAX MA5671A SC transceiver) which works seamlessly in my Powerconnect 5424. I use one SFP port essentially as a media converter to my router (vlan 35) and then back to the switch (vlan 1). This has worked without any issue for months.
I wanted to move to a POE capable switch and picked up a 5524P. I have been able to get the 5524P to recognize the transceiver by setting the port speed to 1000. The switch reports that the link is up (show fiber-ports optical-transceiver) but I can't seem to establish a connection. The LEDs also seem to show activity.
is there something else I can do to try to identify the problem?
So it tried setting the trunk port to access and still no luck. here are some of the diagnostics I recorded in an effort to provide all the information you might need.
The one thing I noticed is that the diagnostic of the transceiver is not providing as much information on the 5524P as the 5424.
Port Temp Voltage Current Output Input LOS [C] [Volt] [mA] Power Power [mWatt] [mWatt] ----------- ------ ------- ------- ------- ------- --- te1/0/1 0 0.0 0.0 1.00 1.00 No

from the 5424:

You could try to assign vlan 35 to the PC access port and assign the appropriate IP address. (or assign an IP address to interface VLAN 35 - same same). To check if you at least have a connection before the router.
I'm not sure I understand the proposal. My router is not only acting as a firewall but is also establishing a pppoe connection, which is why my router is necessary. I can try to have a computer establish the pppoe connection instead of the router.
I'll give it a try and see if there is a different result but I don't really understand why this would make a difference.
I may not be able to get back to this for a week as I will be traveling but any ideas continue to be welcome.
If you're absolutely sure the router/firewall and cables is working as it should, It shouldn't make a difference, but in my experience it's easier to test if you simplify the setup as much as possible.
Sometimes you get surprised where the issues lie.. I have never experienced any SFP errors when the link is up.. usually, if the transceiver is faulty, you wont get a link at all.. which is what leads me to think there's something else going on. I could be wrong though.
If the ports from ISP -> Router is set to switchport mode access and VLAN 35 (depending on how the ISP port is configured) and the port from router -> PC is vlan 1, the switch configuration should be good.
Which is why I would try to take out the router of the equation - that is my thought process, if you don't agree feel free to wait for other suggestions :)
I ended up buying a $25 media converter to go from GBIC to ethernet and no longer need the switch to fully recognize the transceiver.
I also tried compatible transceivers (1G and 10G) and those worked so I eliminated the possibility that the SFP ports are bad. At this point I can only guess that it's an incompatibility between the Huawei transceiver and the 5524P that isn't present with the 5424. This may be a result of the SFP+ port in the 5524P vs SFP in the 5424.
Unfortunate that I was not able to resolve the problem but worked around it.
Thanks for the help. I may keep tinkering in the future but for now I'm putting this issue to rest.

Port g2 goes to the firewall on the 5424. This will be done by port 1 (gigabitethernet1/0/1) for the 5524P.
ports 17,18 and 19,20 will be connected in NASs once I get this issue resolved.
Thanks
