Removing a Power Supply from a QFX5200
Before you remove a power supply from a QFX5200, ensure that you have taken the necessary
precauons to prevent electrostac discharge (ESD) damage (see "Prevenon of Electrostac Discharge
Damage" on page 194).
Ensure that you have the following parts and tools available to remove a power supply from a QFX5200:
• ESD grounding strap
• Anstac bag or an anstac mat
• Phillips (+) screwdriver, number 2 (DC power supply)
The QFX5200 is shipped from the factory with two power supplies. Each power supply is a hot-
removable and hot-insertable eld-replaceable unit (FRU) when the second power supply is installed and
running. You can install replacement power supplies in the two slots next to the fan modules without
powering o the switch or disrupng the switching funcon.
CAUTION: Replace the power supply with a new power supply within 1 minute of
removal to prevent chassis overheang.
To remove a power supply from a QFX5200 (see Figure 59 on page 133 and Figure 60 on page 133):
1. Place the anstac bag or the anstac mat on a at, stable surface.
2. Aach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis.
