Installing a Network Module in a QFX3100 Director Device

QFX3100 Director devices have two network module slots on the front panel. Network modules are field-replacable units (FRUs).

Note: The Director device requires powering off before installation or removal of the network module.

• Ensure that you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

• ESD grounding strap

1. Attach the ESD grounding strap to your bare wrist, and connect the strap to a site ESD point.
2. Power off the QFX3100 Director device. See Powering Off a QFX3100 Director Device.
3. If the network module slot has an installed network module, remove the network module. See Removing a Network Module from a QFX3100 Director Device.
4. Taking care not to touch network module components, pins, leads, or solder connections, remove the network module from its bag.
5. Ensure that the network module is properly aligned with the network module slot. The network module faceplate should be aligned so the ports are numbered 0 through 3 from left to right.
6. Insert the network module into the network module slot, and gently push the module all the way into the slot until the module is seated flush in the network module slot.

   Caution: Do not use too much force to seat the network module flush into the network module slot. If backpressure is preventing the network module from seating flush in the network module slot, remove the network module from the slot and retry the procedure, taking care to ensure that the network module is properly aligned with the network module slot.

7. Tighten both screws on the network module, using your fingers.
8. Power on the QFX3100 Director device. See Powering On a QFX3100 Director Device.
