NOTE: When an SFP transceiver is inserted into a management port, the corresponding RJ-45
management port (C0 or C1) is disabled. Either RJ-45 or SFP management ports can be used,
but not both.

Chassis serial number label and ESD point
NOTE: The chassis serial number ID label is located on a sliding panel on the top right of the
front panel on a QFX3600 device (see Figure 23 on page 50). To use the sliding panel as an
ESD point, pull the sliding panel partway out of the chassis, and connect a tape-style ESD
grounding strap to the panel.

Access and uplink ports—The QFX3600 device has sixteen 40-Gbps ports labeled Q0 through Q15 that
support quad small form-factor pluggable plus (QSFP+) transceivers.
•
If you are using the QFX3600 device as a Node device in a QFabric system, by default, four ports
(labeled Q0 through Q3) are configured for uplink connections between your QFX3600 Node device
and your Interconnect device, and twelve ports (labeled Q4 through Q15) use QSFP+ direct-attach
copper (DAC) breakout cables or QSFP+ transceivers with fiber breakout cables to support 48 10-Gigabit
Ethernet interfaces for connections to either endpoint systems (such as servers and storage devices)
or external networks. Optionally, you can choose to configure the first eight ports (labeled Q0 through
Q7) for uplink connections between your QFX3600 Node device and your Interconnect device and
ports Q2 through Q15 for 10-Gigabit Ethernet connections to either endpoint systems or external
networks. See Determining Transceiver Support for QFabric Systems.
•
If you are using the QFX3600 device as a standalone switch, by default, all 16 QSFP+ ports (Q0 through
Q15) are configured as 40-Gigabit Ethernet (xle) ports. Optionally, you can choose to configure each
port to operate as 10-Gigabit Ethernet (xe) ports. The number of ports supported is release dependent.
See Configuring the Port Type on QFX3600 Standalone Switches for your release for more information
about configuring the port type. You can use QSFP+ direct-attach copper (DAC) cables, QSFP+ DAC
breakout cables, or QSFP+ transceivers. You can use QSFP+ transceivers to create four 10-Gigabit
Ethernet ports by using a fiber breakout cable to distribute the interfaces to four 10GBASE-SR SFP+
transceivers. (Juniper Networks does not sell fiber breakout cables, they must be purchased separately.)
See “Determining Interface Support for the QFX3600 Device” on page 140.
