Before you remove a management board from 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 192).
Ensure that you have the following parts and tools available to remove a management
board from a QFX3500 device:
•
ESD grounding strap

Antistatic bag or an antistatic mat
To remove a management board from a QFX3500 device (see Figure 123 on page 370):
1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
2. Ensure that the QFX3500 device is powered off. See “Powering Off a QFX3500 Device”
on page 298.
3. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
4. Slide the locking lever toward the handle until it stops.
WARNING: To avoid injury, do not touch the fan with your hands or any
tools as you slide the management board out of the chassis—the fan may
still be running.
5. Grasp the management board handle and pull firmly to slide the management board
halfway out of the chassis.
6. When the fans stop spinning, slide the management board completely out of the
chassis.
7. Place the management board in the antistatic bag or on the antistatic mat placed on
