Setting up SFP SG500

EE Folks:

I have two switches that I am trying to set up a 150m fiber LC/LC 50/125 fiber and I am having some trouble.

The Cisco switch is a SG500-52P with a Fiber card installed in G49 and when I look at it in the Management View it shows 1000m-ComboC and that it is "down". On the other end, I have a HP 4208vl switch also with a LC fiber card installed in port B21 and it shows that the card is installed but that the link is down.

What am I missing to get this set up and a vlan untagged to the port so I can get data back and forth between the two switches.

Oh and the fiber is Multimode

could you have the cables mis-connected i.e. TX <> TX vs TX <> RCV

No, after a few days and several purchases of different types/brands of fiber the card was bad.
