Front Panel of a QFX3600 Device

 

The front panel of the QFX3600 device consists of the following components:

  • LCD panel—The LCD panel displays the device hostname and the number of active alarms.

    Tip

    Alternatively, you can use the show chassis lcd CLI command to view what is currently displayed on the LCD panel.

  • Chassis status LEDs

  • USB port

  • Console (CON) port

  • Management ports—The QFX3600 device has four management ports. The ports labeled C0 and C1 are 1000BASE-T RJ-45 ports, and the ports labeled C0S and C1S are 1-Gbps SFP ports.

    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 1). 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.
