down. Likewise, when an EX4600-EM-8F is running on the QFX5100-24Q and is swapped with a
QFX-EM-4Q, the interfaces temporarily go down, which can cause a short disruption in traffic.

QFX5100-96S
As shown in Figure 15 on page 30, the QFX5100-96S switch is a is a 10-Gigabit Ethernet Enhanced
Small Form-Factor Pluggable (SFP+) top-of-rack switch with 96 SFP+ ports and 8 Quad SFP+ (QSFP+)
ports. Each SFP+ port can operate as a native 10 Gigabit port, when 10 Gbps optics are used. The SFP+
ports can also run at 1 Gbps, or at 100 Mbps speeds when 1_Gigabit optics are inserted. QSFP+ ports
96 and 100 can operate at native 40 Gbps speed or can be channelized to 4 independent 10 Gbps port
speeds. The 8 QSFP+ ports can be used as either access ports or as uplinks. The QFX5100-96S switch
has a 2 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 QFX5100-96S can be used as:
•
A standalone switch.
•
A member 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 in a ring topology.
•
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 20 total devices in a spine and leaf topology. Of those 20 devices, 4 QFX5100 devices can be
configured as spine devices.
In a mixed environment with QFX5100-24Q, QFX5100-98S and EX4300, use the QFX5100-24Q as
the spine device and the QFX5100-96S and EX4300 as a leaf devices. You may use the QFX5100-96S
as a spine in an all QFX5100-96S VCF or in a VCF that has a mixture of QFX5100-96S and EX4300.

A line card in a mixed QFX5110 Virtual Chassis.
A QFX5110 Virtual Chassis must have a QFX5110-32Q as the primary. Only QFX5110 switches and
select models of QFX5100 switches can participate in a QFX5110 Virtual Chassis. Junos OS Release
17.3R1 or later is required for QFX5110 Virtual Chassis.
