Wired Intelligent Edge

Hi all,

This seems to have Aruba TAC stumped so far, so i'm reaching out to see if anyone has experienced a similar issue.

We have an Aruba 2930M 4 switch stack. I've recently added a JL081A to provide 10GbE connectivity for a workstation with an Intel X550T2BLK 10GbE card.

The JL081A module appears to install correctly, there is a solid green light on it and it is recognised on the web interface/SSH access whereby I can designate VLANS and name the ports. Unfortunately that is as far as I can get with it. I'm unable to get the hardware link up between the switch and workstation or a 10GbE connection on a Synology NAS. Unfortunately at this point I don't have any other 10GbE copper devices to test with.

I’ve tried the expansion module in 3 stack members – same issue.

I’ve used different, new CAT6a patch leads.

I’ve used the same patch leads to directly patch the PC into the NAS and Windows instantly shows it as a 10GbE connection.

Aruba TAC sent out a replacement JL081A to rule out faulty hardware but it hasn't made any difference.

Is anybody able to suggest anything else I could try?

Thanks in advance.

Start with providing few logs (port(s) status, port(s) configurations on both ends, output of show logging when you connect your NAS to one JL081A port, etc.)...help us to help you...to me, from what you wrote, potentially it looks like a Configuration issue, not necessarily an Hardware issue. Specify model of Synology NAS, DSM version, etc...and try to be as much detailed as you can...no hardware link up means Layer 1 (so physical) problem.

Hello

I have stack 3810M (JL075+JL072) with installed JL085a (JL075 ports 1/A1-1/A4). Everything fine, but I'm not able to get the PoE active.
When i tried
core(config)# Power-over-ethernet pre-std-detect ports 1/A1-1/A4
PoE is not supported on ports 1/A1-1/A4
If i ...
core(config)# power-over-ethernet member 1
None of the specified stack members support PoE.

What`s wrong? Help me please

I had the same issue and wanted to share my solution.

I have a stack of 2930M switches running WC.16.11.0001.  When an JL081A module was inserted (very firmly) it booted and showed an "Up" status.  However, connecting devices to the module's ports failed to bring up the ports.  I tried multiple modules in multiple switch stack members with the same behavior.  I tried rebooting the entire stack multiple times.  I tried connecting both 1Gb and 10Gb devices.

My solution was

1. "unprovision" the module
2. physically remove the module
3. pre-"provision" the module
4. physically insert the module
5. shutdown the specific switch the module is plugged into
6. unplug and replug the switch the module is plugged into

After this process the ports on the module come up when connected to.  Both 1Gb and 10Gb connected devices will bring the port up.

Commands when the module is in switch 1 slot A

Stumbled on this post yesterday.....

Upgraded software on a couple of 2930M stacks for a client from WC.16.05.0004 --> WC.16.11.0027 (7 year difference there!) and am seeing this post-upgrade.

They had APs connected to those smart rate ports on the modules; ended up moving those to 1G ports while we sort this out.

We weren't in a position to reboot the switches once we discovered the issue.

The modules DO provide PoE power to the APs, but the ports never link up.  I did try connecting other devices to the ports and see the same issue.

These are both 3-switch stacks.  The SmartRate module in the Stack Commander DOES work; the modules in the other two switches are exhibiting the issue.

We're going to schedule another maint window to perform the procedure mentioned by @chalowther and see if that gets them working.  If not we'll open a TAC case.
