Figure 2: QFX5100-24Q Switch
The QFX5100-24Q can be used as:
•
A standalone switch.
• 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.
BEST PRACTICE: Use QFX5100-24Q switches as master and backup in
a QFX Virtual Chassis; use as spine devices in a VCF.
As shown in Figure 3 on page 5 , the QFX-EM-4Q is an expansion module for the
QFX5100-24Q. The module provides 4 additional QSFP+ ports that can be hot-inserted
or hot-removed from the switch.

QFX5100-96S
As shown in Figure 4 on page 6 , 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
Gbps port or as a 1 Gbps port. 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 model can be ordered with either ports-to-FRUs or FRUs-to-ports airflow
