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 198).
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 54 on page 129):
1. Ensure that the QFX3500 device is powered off (see “Powering Off a QFX3500 Device”
on page 143). 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 theycan onlybe inserted into the QFX3500 device model
that supports the same airflow type. See “Cooling System and Airflow for
a QFX3500 Device” on page 29 for more information.
