Installing a Management Board in a QFX3500 Device

 

A QFX3500 device has a single field-replaceable unit (FRU) management board.

Caution

You must power off the QFX3500 device before replacing the management board.

Note

The management board provides FRU-to-port or port-to-FRU airflow depending on the device model you purchase.

Before you install a management board in a QFX3500 device, ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

Ensure that you have the following parts and tools available to install a management board in a QFX3500 device:

  • ESD grounding strap

To install a management board in a QFX3500 device (see Figure 1):

  1. Ensure that the QFX3500 device is powered off (see Powering Off a QFX3500 Device). If the QFX3500 is operating as a Node device in a QFabric system, ensure that traffic is diverted in an orderly shutdown by using the shutdown procedure in Adding or Replacing a Node Device in a QFabric Node Group .
  2. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
  3. Taking care not to touch the connectors, remove the management board from its bag.
  4. Using both hands, align the tray with the management board slot on the front panel of the chassis and slide it in until it is fully seated and the locking lever slides into place.Caution

    Damage can occur if you attempt to install a management board into a chassis with a different airflow direction. Check the device model to ensure that you are installing a management board with the same airflow direction as the chassis. The management boards are designed so that they can only be inserted into the QFX3500 device model that supports the same airflow type. See Cooling System and Airflow for a QFX3500 Device for more information.
