Replacement HDD module for the HDD module slot
To remove an HDD module from a QFX3100 Director device (see Figure 94 on page 318):
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.
