Installing a DC Power Supply in the SRX3400 Services Gateway

Note: For the services gateway to meet NEBS and ETSI standards, both DC power supplies must be enhanced DC power supplies. See SRX3400 Services Gateway NEBS and ETSI Compliance for more information.

Note: The same DC power supply is used in both the SRX3400 and SRX3600 Services Gateways. However, this power supply is not interchangeable with that used in the SRX1400 Services Gateway. The SRX1400 Services Gateway power supply will fit into the SRX3400 Services Gateway, but will not work properly. You can identify the SRX1400 Services Gateway power supply by the plastic air filter assembly installed over the cooling air inlet as shown in Figure 38.

Types

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.
  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 SRX3400 Services Gateway.
  3. Orient the power supply so that the locking lever is on the left, as shown in Figure 39.

  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.

See Connecting the SRX3400 Services Gateway to a DC Power Source for information on connecting the power supply to DC power.
