Removing a Power Supply from the PTX1000
The power supplies in a PTX1000 are hot-removable and hot-insertable field-replaceable units (FRUs)—you
can remove and replace them without powering off the PTX1000 or disrupting routing functions.
CAUTION: Replace the power supply within 30 seconds of removal to prevent chassis
overheating. Before removing the power supply, ensure you have a replacement power
supply available.
Before you remove a power supply from a PTX1000, ensure that you have taken the necessary precautions
to prevent electrostatic discharge (ESD) damage (see “Prevention of Electrostatic Discharge Damage” on
page 161).
Ensure that you have the following parts and tools available:
•
ESD grounding strap
•
Antistatic bag or an antistatic mat
CAUTION: Do not mix AC and DC power supplies in the same chassis.
To remove a power supply from a PTX1000 (see Figure 40 on page 102):
1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
2. To prevent damage to the equipment caused by static discharge, attach an electrostatic discharge (ESD)
grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
