Cisco UCS 2200 Series Fabric Extenders bring the unified fabric into the blade server enclosure providing multiple 10 Gigabit Ethernet connections between blade servers and the fabric interconnect simplifying diagnostics cabling and management. It is a second-generation I/O module (IOM) that shares the same form factor with the first-generation Cisco UCS 2100 Series Fabric Extenders IOM and is backward-compatible with the shipping Cisco UCS 5108 Blade Server Chassis.
