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” on page 242 ).
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 164 on page 461 ):
1. Ensure that the QFX3500 device is powered off (see “Powering Off a QFX3500 Device” on page 414 ).
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.
