QFX5100 Switch Hardware Overview
The QFX5100 line of switches is Juniper Network’s second generation of top-of-rack
switch solutions for data centers and campus distribution or aggregation environments.
The QFX5100 portfolio consists of high-performance fixed-configuration switches that
add higher port densities, additional scalability, and improved latency to the QFX Series.

QFX5100 Hardware
QFX5100 line of switches offer two compact 1 U models and a 2 U model that provide
wire-speed packet performance, very low latency, and rich set of Layer 2 and Layer 3
features. In addition to a high-throughput Packet Forwarding Engine, the performance
of the control plane running on all the QFX5100 models is enhanced by the 1.5 Ghz dual
core Intel CPU with 8 GB of memory and 32 GB of solid-state drive (SSD) storage.
The QFX5100 line of switches include both 10GE and 40GE fixed-configurations:

QFX5100-48S
As shown in Figure 1 on page 4 , the QFX5100-48S is a 10-Gigabit Ethernet Enhanced
Small Form-Factor Pluggable (SFP+) top-of-rack switch with 48 SFP+ ports and 6
Quad SFP+ (QSFP+) ports. Each SFP+ port can operate as a native 10 Gbps port or
be channelized into 10 independent 1Gbps ports. Each QSFP+ port can operate at
native 40 Gbps speed or as 4 independent 10 Gbps port speeds. The 6 QSFP+ ports
can be used as either access ports or as uplinks. The QFX5100-48S provides full duplex
