Removing an HDD Module from a QFX3100 Director Device

QFX3100 Director devices have two 2-terabyte (TB) hard disk drive (HDD) module slots on the front panel. HDD modules are field-replaceable units (FRUs). At least one HDD module should always be installed in a QFX3100 Director device.

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

Ensure that you have the following parts and tools available:

• ESD grounding strap
• Phillips (+) screwdriver, number 2
• Antistatic bag or antistatic mat
• Replacement HDD module for the HDD module slot

1. Attach the ESD grounding strap to your bare wrist, and connect the strap to a site ESD point.
2. Place the antistatic bag or the antistatic mat on a flat, stable surface.
3. Unscrew both captive screws counterclockwise using your fingers. If you are unable to unscrew the captive screws using your fingers, use the screwdriver.
4. Gently pull the HDD module toward you and out of the HDD module slot, being careful to keep one hand underneath the module to support it when it is removed from the chassis.

   Note: If the Director device is powered on, at least one HDD module must be installed at all times. This step should only be performed when an HDD module in the other HDD slot is installed and operational.

5. Place the HDD module in the antistatic bag or on the antistatic mat.
