Installing A Dc Power Supply On The Srx550 Services Gateway - Juniper SRX550 Hardware Manual

Installing a DC Power Supply on the SRX550 Services Gateway

To install a DC power supply:
1. Ensure that the voltage across the DC power source cable leads is 0 V and that there is no chance that
the cable leads might become active during installation. To ensure that all power is off, locate the circuit
breaker on the panel board that services the DC circuit, switch the circuit breaker to off position (O),
and tape the switch handle of the circuit breaker in the off position.
2. Attach an electrostatic discharge (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. Orient the power supply so that the locking lever is on the left, as shown in
Figure 18: Installing a DC Power Supply on an SRX550 Services Gateway
4. Using both hands, slide the power supply straight into the chassis until the power supply is fully seated
in the chassis slot. The power supply faceplate should be flush with any adjacent power supply faceplate.
5. Tighten the captive screws on the lower edge of the power supply faceplate.
6. Remove the clear plastic cover protecting the terminal studs on the faceplate.
