Removing a Management Board from a QFX3500 Device
QFX3500 devices have a single field-replaceable unit (FRU) management board on the
front panel.
CAUTION: You must power off the QFX3500 device before replacing the
management board. If theQFX3500is 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 .
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 198).
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 55 on page 131):
1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
2. Ensure that the QFX3500 deviceis powered off. See“Powering Off a QFX3500 Device”
on page 143 or Adding or Replacing a Node Device in a QFabric Node Group in QFabric
systems.
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 asyou slide the managementboardout of the chassis—thefanmight
still be running.
