“Brocade Extended Fabrics License

[yeganeh]

I’ve decided to use Brocade 7500 to connect two sites via dark fiber. The distance between them is about 37Km and refer to Brocade documents, I should order “Brocade Extended Fabrics License” for Brocade 7500. I have searched in the web and I just found Extended fabrics license for Brocade switches and director like :

BR-3900EXF-02 Extended Fabrics (EF) (3200, 3250, 3800, 3850)
BR-MENTEXF-01 Extended Fabrics(EF) (Brocade 4900 Switch)

Would you please tell me the part number of “Extended Fabrics License” of “Brocade 7500”.
