Networks Junos OS. The switch may not be converted to Junos OS without an additional license. The
switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC power supplies.
The QFX5100-48TH can only be used as a satellite device in a Junos Fusion system.

QFX5100-24Q
As shown in Figure 10 on page 26 , 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 switch 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 operating as a standalone switch and
fully populated with QFX-EM-4Q Expansion Modules, the QFX5100-24Q switch is equivalent to 80
10 Gbps interfaces and 4 40-Gbps interfaces. 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 Device” on page 32 . 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.

The QFX5100-24Q can be used as:
•
A standalone switch.
•
An interconnect device in a QFX3000-M QFabric system.
•
A Node device in a QFabric system.
The QFX5100-24Q is supported on both the QFX3000-G and QFX3000-M QFabric systems. A
QFX5100-24Q Node device is equivalent to 80 10-Gbps interfaces and 4 40-Gbps interfaces.
