Console (CON) port. An optional GPS time of day (TOD) device is also supported. To connect to both a console and a TOD device simultaneously, you must use the breakout cable that is provided with the device.

The management panel on an ACX7100-32C router displays the router product number, and consists of the following components:

  • Status LEDs—ALM, SYS, MST, and ID LEDs.

  • Management (MGMT) port—10/100/1000BASE-T management port that uses an RJ-45 connector to connect to a management device for out-of-band management. See Connect an ACX7100-32C Router to a Network for Out-of-Band Management.

  • Console (CON) port—uses an RJ-45 connector to connect to a console management device. An optional GPS time of day (TOD) device is also supported. To connect to both a console and a TOD device simultaneously, you must use the breakout cable that is provided with the device.

    Note:

    If you connect to both console and ToD simultaneously using a breakout cable, you must ensure that you have not configured the log-out-on-disconnect statement at the [edit system ports console] hierarchy level.

  • USB port for image updates

  • Reset button to reset the device.

  • SMB connector ports that support 1-PPS and 10-MHz timing devices.

Management Port LEDs on ACX7100-32C Routers

The ACX7100-32C has one management port that has separate LEDs to indicate link status and link activity. The port is located on the management panel and is labeled MGMT. Figure 2 shows the location of the LEDs.

Port Panel of ACX7100-32C Routers

The port panel of an ACX7100-32C router has the following port configurations:

  • Thirty-two quad small form-factor pluggable (QSFP28) transceivers (ports 0 through 31) that operate at 100-Gbps speed when you use QSFP28 transceivers or at 40-Gbps speed when you use QSFP+ transceivers.

    Note:

    You can configure port 31 as a 1-Gigabit SFP grandmaster port by using a QSA adapter to convert the QSFP28 port to a 1-Gigabit SFP port.

  • Four double density quad small-form factor pluggable (QSFP56-DD) ports (ports 32 through 35) that are configured as 400GbE ports by default.

    The QSFP56-DD network ports support:

    • QSFP56-DD transceivers

    • QSFP28-DD transceivers

    • QSFP28 transceivers

    • QSFP+ transceivers

    • Active optical cables (AOC)

    • Direct attach copper (DAC) cables

Note:

At an ambient temperature greater than 40°C (at 6000 feet altitude above sea level), you can install only 100G transceivers in any of the QSFP56-DD ports.

Note:

See Guidelines for Using QDD-400G-ZR, QDD-400G-ZR-M, JCO400-QDD-ZR, and JCO400-QDD-ZR-M Transceivers before you install QDD-400G-ZR and QDD-400G-ZR-M transceivers.

To understand all the potential restrictions and validate different port configurations on an ACX7100-32C router, use the Port Checker Tool.

Guidelines for Using QDD-400G-ZR, QDD-400G-ZR-M, JCO400-QDD-ZR, and JCO400-QDD-ZR-M Transceivers

Before you install the QDD-400G-ZR, QDD-400G-ZR-M, JCO400-QDD-ZR, and JCO400-QDD-ZR-M transceivers, you must update the temperature thresholds of the inlet sensors to facilitate an increase in fan speeds. This prevents the transceivers from powering off. We recommend that you update the temperature thresholds at ambient room temperature (23°C to 27°C).

Update the Temperature Thresholds

The following example requires you to navigate various levels in the configuration hierarchy. For information about navigating the CLI, see the CLI User Guide.

To update the temperature thresholds, in configuration mode, perform the following steps on an ACX7100-32C device:

  1. Update the temperature thresholds for the Main PCBLeft temperature sensor by executing the following commands:

    for QDD-400G-ZR and QDD-400G-ZR-M:

    for JCO400-QDD-ZR and JCO400-QDD-ZR-M:

  2. Update the temperature thresholds for the Main PCBRight temperature sensor by executing the following commands:

    for QDD-400G-ZR and QDD-400G-ZR-M:

    for JCO400-QDD-ZR and JCO400-QDD-ZR-M:

  3. Commit the configuration.

In the above example, the threshold values are updated to support the QDD-400G-ZR-M and JCO400- QDD-ZR-M transceivers. If you are not using the QDD-400G-ZR-M and JCO400-QDD-ZR-M transceivers, you will need to delete the changes made to the temperature thresholds. To do this, in configuration mode, perform the following steps:

  1. Delete the Main PCBLeft and Main PCBRight temperature sensors.

  2. Commit the configuration.

Verify the Updated Temperature Thresholds

You can verify the changes made to temperature thresholds by using any of the following methods:

  • In operational mode, run the show chassis enhanced-temperature-thresholds command to view the configured thresholds for all the sensors.

  • In configuration mode, execute the following command:

Network Port LEDs on ACX7100-32C Routers

Each ACX7100-32C network port uses a single bicolored LED to indicate link status, activity on the link, or a fault condition. Figure 4 and Figure 5 show the location of the LEDs on an ACX7100-32C device.
