Front Panel of a QFX3600-I Interconnect Device

The front panel of the QFX3600-I Interconnect device consists of the following components:

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


    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-I Interconnect 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. These ports are used to connect the QFX3600-I Interconnect device to the QFabric system control plane and management network.


    When an SFP is inserted into a management port, the RJ-45 management ports (C0 and C1) are disabled.

  • Chassis serial number label and ESD point


    The chassis serial number ID label is located on a sliding panel on the top right of the front panel on a QFX3600-I Interconnect 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 clip-style or tape-style ESD grounding strap to the panel.

  • Uplink ports—The QFX3600-I Interconnect device has sixteen 40-Gbps ports labeled Q0 through Q15 that support quad small form-factor pluggable plus (QSFP+) transceivers. See The Hardware Compatibility Tool.

  • Uplink port LEDs
