Removing an AC Power Supply from the SRX650 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, 14.6 oz (1.32 kg).
CAUTION: Do not leave a power supply slot empty for more than 30 minutes
whilethe services gatewayis 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 SRX650 Services Gateway” on page 168.
3. Press the latch to the left of the power outlet (see Figure 24 on page 146).
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.
