Installing an AC Power Supply in an SRX4200 Services Gateway
CAUTION: Do not mix AC and DC power supplies in the same chassis.
To install an AC power supply (see Figure 21 on page 57 ):
1.
Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD
point on the chassis.
2.
If the power supply slot has a cover panel on it, with one hand slide the ejector lever
toward the left until it stops and using the other hand pull the handle of the cover
panel outward to remove it. Save the cover panel for later use.
3.
Taking care not to touch power supply pins, leads, or solder connections, remove the
power supply from the bag.
4.
Using both hands, place the power supply in the power supply slot on the rear panel
of the services gateway and slide it in until it is fully seated and the ejector lever fits
into place. You will hear a distinct click when the power supply is fully seated in the
chassis.
