PS6010 No 10GB Uplink

I have tried numerous SFP+ from different vendors even purchased new 2CM32 Twinax Cables but I still do not get a link. Is there something I am missing, maybe a no shut command or something. I am extremely frustrated at this point, I am connecting to a Cisco Nexus 5010 with newest firmware.

Please Help,

Thanks,

Joe

The issue I am seeing is that there is no Light coming out of the transceivers. I cannot configure until I can get a network up link. I will order some Dell PN: WTRD1 and see if that brings the ports online, or at least get the transceivers to emit the fiber connection light. My 6510 is using 3M Dell OEM 10GBE SFP+ TurboTwin Cable PN: 02CM32 2CM32 it has the same type 10 controllers maybe the firmware is different I will have to check.

Thanks For the speedy response by the way.

Hey Don,

Turns out it wasn't the SFP+ or Twinax cables, the ports were shut down as I suspected.

After hours of frustration, I decided to go into Boot mode ( CTRL/P)  and saw ifconfig in the options decided to check out the commands: 

ifconfig -i xgmac_0

I Got Starting Interface then

 ifconfig -i xgmac_0 -a IP_ADDRESS -n MASK -g GATEWAY

then bam finally got a link light.

Reset the Equallogic now it is up and running.

Hopes this help any who had the same issue.

Now the issue I am having is:

2017 Jan 6 16:16:12 SMNCORE-1 %$ VDC-1 %$ %LLDP-1-NO_DCBX_ACKS_RECV_FOR_LAST_10_PDUs: No Acks have been received on Interface Eth1/9 for last 40 DCBX PDUs

after 100 DCBX PDUs the port shuts down.

Thanks in advance.
