Hi, i can provide you with the following info at my best;
Cisco Nexus 5500 Series with QSFP+ GEM
The QSFP+ GEM (N55-M4Q) is a generic expansion module (GEM) that provides 16x10 Gigabit Ethernet SFP+ in a 4 x QSFP+ form factor. This module does not support native 40 Gigabit Ethernet on the QSFP+ port. This module is supported on all Cisco Nexus 5500 chassis (Cisco Nexus 5548P, Cisco Nexus 5548UP, Cisco Nexus 5596UP, and Cisco Nexus 5596T). This module is suitable for any expansion slot on the Cisco Nexus 5500 Series and you can populate all the expansion slots on the Cisco Nexus 5596 chassis with N55-M4Qs. There is no additional configuration needed to specify the operation mode of the QSFP+ ports because all the ports only operate in 4 x10 Gigabit Ethernet mode. The numbering of the ports uses the following convention(see Figure 2-2):
Note The argument, chassis_ID, is not optional when addressing the host interfaces of a Cisco Nexus 2000 Series Fabric Extender.

●Cisco Nexus 5672UP Switch: The Cisco Nexus 5672UP (Figure 1) is a 1RU 10 and 40 Gigabit Ethernet switch offering wire-speed performance for up to seventy-two 10 Gigabit Ethernet ports (using Quad Small Form-Factor Pluggable [QSFP] breakout cables). Cisco Nexus 5672UP Switches are Layer 2 and 3 non-blocking 10 and 40 Gigabit Ethernet and FCoE-capable switches with up to 1.44 terabits per second (Tbps) of internal bandwidth. The Cisco Nexus 5672UP offers 48 fixed 1 Gigabit and 10 Gigabit Ethernet ports of which 16 ports can be unified ports (UP). The 16 unified ports provide 8/4/2-Gbps Fibre Channel as well as 10 Gigabit Ethernet and FCoE connectivity options. The Cisco Nexus 5672UP also offers 6 ports of 40 Gbps using QSFP transceivers for Ethernet and FCoE support. The Cisco Nexus 5672UP has three fan modules and two power supplies. The Cisco Nexus 5672UP is VXLAN ready, with VXLAN support in bridging and routing modes, on all ports at line rate, enabling the migration of virtual machines between servers across Layer 3 networks.
