Powering Off a QFX5100 Switch
Before you power off a QFX5100 switch:
• Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage. See
“Prevention of Electrostatic Discharge Damage” on page 142 .
•
Ensure that you do not need to forward traffic through the switch.
Ensure that you have the following parts and tools available to power off the switch:
•
An ESD grounding strap
•
An external management device such as a PC
• An RJ-45 to DB-9 rollover cable to connect the external management device to the
console port
To power off a QFX5100 switch:
