Figure 7: EX4600-EM-8F Expansion Module
NOTE: The EX4600-EM-8F is not supported on the QFX5100-24Q running in QFabric
systems.
The QFX5100-24Q is congured for the QFX-EM-4Q by default, but any combinaon of the two
modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an
EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the new conguraon causes the
interfaces to temporarily go down. Likewise, when an EX4600-EM-8F is running on the
QFX5100-24Q and it is swapped with a QFX-EM-4Q, the interfaces temporarily go down, which can
cause a short disrupon in trac.
• QFX5100-24Q-AA
As shown in Figure 8 on page 10, the QFX5100-24Q-AA is a 1 U, top-of-rack, 40-Gigabit Ethernet

Gigabit Ethernet or as a set of 4 independent 10-Gigabit Ethernet ports. The QFX5100-24Q-AA can
also be congured to support twenty-four 40-Gigabit Ethernet interfaces or ninety-six 10-Gigabit
Ethernet interfaces using breakout cables (channelizaon mode) with 1280 Gbps output. The switch
can be ordered with either ports-to-FRUs or FRUs-to-ports airow and with AC or DC power
supplies. The QFX5100-24Q switch provides full duplex throughput of 2.56 Tbps.
The QFX5100-24Q-AA module bay can accommodate a single Packet Flow Accelerator (PFA)
double-wide expansion module (QFX-PFA-4Q) or two single-wide oponal expansion modules (two
or one each of QFX-EM-4Q and EX4600-EM-8F). The QFX-PFA-4Q, which features a high-
performance eld-programmable gate array (FPGA), provides four addional QSFP+ ports to the
chassis. Each QFX-EM-4Q adds four QSFP+ ports to the chassis and each EX4600-EM-8F adds eight
10-Gigabit SFP+ ports to the chassis. The QFX-EM-4Q ports can also be congured as either access
ports or uplink ports, but only ports 0 and 2 can be channelized using port mode. For full details on
the dierent port channelizaon modes, see "Port Panel of a QFX5100-24Q Device" on page 20.
All ports on the QFX5100-24Q and QFX-EM-4Q can be congured as either access ports or uplink
ports.

This switch provides the hardware support to enable PTP boundary clocks by using the QFX-PFA-4Q
module. The QFX5100-24Q-AA also supports GPS in and out signals when QFX-PFA-4Q is installed.
The CPU subsystem of this switch includes a 2-port 10-Gigabit Ethernet network interface card (NIC)
to provide a high bandwidth path or to alternate trac path to guest VMs directly from the Packet
Forwarding Engine.

The QFX5100-24Q-AA can be used as a standalone switch that supports high frequency stascs
collecon. Working with Juniper Networks Cloud Analycs Engine, this switch monitors and reports
the workload and applicaon behavior across the physical and virtual infrastructure.
The QFX5100-24Q-AA supports the following expansion modules to increase port density:
• QFX-PFA-4Q (double-wide), which provides four addional QSFP+ ports. See Figure 9 on page
10.
Figure 9: QFX-PFA-4Q Expansion Module
• QFX-EM-4Q (single-wide), which provides 4 addional 40-Gigabit Ethernet QSFP+ ports. See
Figure 6 on page 8.

• EX4600-EM-8F (single-wide), which provides 8 addional 10-Gigabit Ethernet SFP+ ports. See
Figure 7 on page 9.
The QFX5100-24Q switch supports the QFX-PFA-4Q and you must take the switch oine before
replacing the expansion module. Any combinaon of EX4600-EM-8F and QFX-EM-4Q is also
supported. These two expansion modules can be hot-inserted or hot-removed. However, when an
EX4600-EM-8F is inserted instead of a QFX-EM-4Q, the new conguraon causes the interfaces to
temporarily go 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 disrupon
in trac.
• QFX5100-96S
As shown in Figure 10 on page 11, 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 nave 10 Gigabit port, when 10 Gbps opcs are used. The
SFP+ ports can also run at 1 Gbps, or at 100 Mbps speeds when 1_Gigabit opcs are inserted. QSFP
+ ports 96 and 100 can operate at nave 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 airow and
with AC or DC power supplies.
Figure 10: QFX5100-96S Port Panel
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.
