Removing an AC Power Supply from the SRX550 Services Gateway
Up to two power supplies can be located at the rear of the chassis on the right side. Each AC power supply
weighs 2 lb (1.32 kg).
CAUTION: Do not leave a power supply slot empty for more than 30 minutes while
the services gateway is operational. For proper airflow, the power supply must remain
in the chassis, or a blank panel must be used in an empty slot.
NOTE: After powering off a power supply, wait at least 60 seconds before turning it back on.
To remove an AC power supply:
1. Switch off the dedicated facility circuit breaker for the power supply, and remove the power cord from
the AC power source. Follow the electrostatic discharge (ESD) and disconnection 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. For more information about ESD, see Preventing Electrostatic Discharge Damage to the
SRX550 Services Gateway.
3. Press the latch to the left of the power outlet (see Figure 28 on page 144 ).
4. After the power supply is unlatched, remove the power cord from the power supply.
5. Pull the power supply straight out of the chassis.
