Figure 4. Rear view of Cisco UCS 5108 Blade Server Chassis with two Cisco UCS 2104XP Fabric Extenders
The Cisco UCS 2104XP Fabric Extender has four 10 Gigabit Ethernet, FCoE-capable, Small Form-Factor
Pluggable Plus (SFP+) ports that connect the blade chassis to the fabric interconnect. Each Cisco UCS 2104XP
has eight 10 Gigabit Ethernet ports connected through the midplane to each half-width slot in the chassis.
Typically configured in pairs for redundancy, two fabric extenders provide up to 80 Gbps of I/O to the chassis.

3.2.3 Cisco UCS Chassis
The Cisco UCS 5100 Series Blade Server Chassis is a crucial building block of the Cisco Unified Computing
System, delivering a scalable and flexible blade server chassis for today's and tomorrow's data center while
helping reduce TCO.
Cisco's first blade server chassis offering, the Cisco UCS 5108 Blade Server Chassis, is six rack units (6RU) high
and can mount in an industry-standard 19-inch rack. A chassis can house up to eight half-width Cisco UCS B-
Series Blade Servers and can accommodate both half- and full-width blade form factors.
Four single-phase, hot-swappable power supplies are accessible from the front of the chassis. These power
supplies are 92 percent efficient and can be configured to support non-redundant, N+ 1 redundant and grid-
redundant configuration. The rear of the chassis contains eight hot-swappable fans, four power connectors (one
per power supply), and two I/O bays for Cisco UCS 2104XP Fabric Extenders.
A passive mid-plane provides up to 20 Gbps of I/O bandwidth per server slot and up to 40 Gbps of I/O bandwidth
for two slots. The chassis is capable of supporting future 40 Gigabit Ethernet standards.
