FEX connected to 7k

[looperzab]

I can't seem to find it anywhere in the documentation, but do the 7k F1 series modules support FEXs or is it only the M1?

The FEXs can only connected to the M1 series right now.

Please check out the following link's table 2:

http://www.cisco.com/en/US/partner/docs/switches/datacenter/sw/5_x/nx-os/release/notes/52_nx-os_release_note.html#wp425651

"Cisco Nexus Fabric Extenders (FEX) are supported  on the 32-port 10-Gigabit Ethernet SFP+ I/O module (N7K-M132XP-12) and  the 32-port 10-Gigabit Ethernet SF P+ I/O module XL (N7K-M132XP-12L). In  addition, all FEX models use only the AC power supply and require  front-to-back airflow."

HTH,
