throughput of 1.44 Tbps. The QFX5100-48S has a 1 U form factor and comes standard
with redundant fans and redundant power supplies. The model can be ordered with
either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies.
Figure 1: QFX5100-48S Switch
The QFX5100-48S can be used as:
• A standalone switch.
•
A Node device in a QFabric system.
The QFX5100-48S is supported on both the QFX3000-G and QFX3000-M QFabric
systems.
• A master, backup, or linecard in a QFX Virtual Chassis.
A QFX Series Virtual Chassis allows you to interconnect up to ten QFX3500,
QFX3600, or QFX5100 switches into one logical device and manage the device as
a single chassis.
• A spine or leaf device in a Virtual Chassis Fabric (VCF).
VCF uses Virtual Chassis technology to interconnect multiple devices into a single
logical device and manage that device as a single logical device inside of a fabric
architecture. VCF architecture supports up to twenty total devices in a spine and
leaf topology.
• QFX5100-24Q
As shown in Figure 2 on page 5 , the QFX5100-24Q is a 40-Gigabit Ethernet QSFP+
switch with 24 high-density QSFP+ ports. Each QSFP+ port can operate as a native
40 Gbps port or as 4 independent 10 Gbps ports. The QFX5100-24Q switch has a 1 U
form factor and comes standard with redundant fans and redundant power supplies.
The model can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with
AC or DC power supplies.
The QFX5100-24Q switch has two module bays for the optional expansion module,
QFX-EM-4Q, which can add a total of 8 additional QSFP+ ports to the chassis. When
fully populated with QFX-EM-4Q Expansion Modules, the QFX5100-24Q switch is
equivalent to 128 10 Gbps interfaces (96 + 16 + 16). Of these total ports, 104 logical
ports are available for 10G port channelization. For full details on the different port
channelization modes, see
“Port Panel of a QFX5100-24Q Switch” on page 18 . All ports
on the QFX5100-24Q and QFX-EM-4Q can be configured as either access ports or as
uplinks. The QFX5100-24Q switch provides full duplex throughput of 2.56 Tbps.
