Removing the SRX4600 Services Gateway AC Power Supply
You can remove an AC power supply without powering off the services gateway or disrupting services
gateway functions.
Ensure that you have the following tools and parts available:
•
Electrostatic discharge (ESD) grounding strap
•
An antistatic bag or an antistatic mat
•
Phillips (+) screwdriver, number 1
•
A cover panel for the power supply slot
NOTE: Before you remove a power supply from the services gateway, ensure that you have
taken the necessary precautions to prevent ESD damage (see Prevention of Electrostatic Discharge
Damage).
CAUTION: We recommend that you install either a replacement power supply or a
cover panel in the empty power supply slot to prevent chassis overheating and dust
accumulation.
NOTE: After powering off a power supply, wait at least 60 seconds before turning it back on.
To remove an AC power supply, see ( Figure 34 on page 93 ):
1. If the AC power source outlet has a power switch, set it to the off (O) position. Follow the instructions
for your site.
2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on
the chassis.
3. Place the antistatic bag or the antistatic mat on a flat, stable surface.
4. Gently pull out the male end of the power cord connected to the power source outlet.
5. Remove the power cord from the power supply faceplate by detaching the power cord retainer and
gently pulling out the female end of the power cord connected to the power supply faceplate.
