Expansion Modules

Expansion modules allow the Cisco Nexus 5596T switch to be configured as cost-effective 10-Gigabit Ethernet switches and as I/O consolidation platforms with native Fibre Channel connectivity.

The Cisco Nexus 5596T switch has three slots that can be used for the following optional expansion modules:

•Ethernet module that provides sixteen 1- or 10-Gigabit Ethernet and FCoE ports using the SFP+ interface

•Fibre Channel plus Ethernet module that provides eight 1- or 10-Gigabit Ethernet and FCoE ports using the SFP+ interface, and eight ports of 8/4/2/1-Gbps native Fibre Channel connectivity using the SFP+/SFP interface

•Unified port module that provides up to sixteen 1- or 10-Gigabit Ethernet and FCoE ports using the SFP+ interface or up to sixteen ports of 8/4/2/1-Gbps native Fibre Channel connectivity using the SFP+ and SFP interfaces. The use of 1- or 10-Gigabit Ethernet or 8/4/2/1-Gbps Fibre Channel on a port is mutually exclusive but can be selected for any of the 16 physical ports per module

•Ethernet module that provides twelve 10GBASE-T ports (N55-M12T). The hardware is FCoE capable

You can hot swap the expansion modules during operations.

Ports

Each port on the Cisco Nexus 5596T is numbered, and groups of ports are numbered based on their function. The ports are numbered top to bottom and left to right.

Figure 1-15shows how ports are numbered and grouped by function.
