Replacing an AC Power Supply on the SRX3400 Services Gateway

Note: For the services gateway to meet NEBS and ETSI standards, both AC power supplies must be Revision 09 or later. See SRX3400 Services Gateway NEBS and ETSI Compliance for more information.

Note: The same AC 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 65.

To replace an AC power supply:

  1. 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.
  2. Remove the power cord from the power supply.
  3. Push the tab on the left edge of the power supply to the right.
  4. Pull the power supply straight out of the chassis using the provided handle. Use one hand to support underneath the supply as you remove it.

  5. Orient the replacement power supply so that the tab is on the left side, as shown in Figure 67.

  6. Using both hands, slide the replacement power supply straight into the chassis until the power supply is fully seated in the chassis slot. Make sure the tab on the left edge of the power supply clicks into place. The power supply faceplate should be flush with any adjacent power supply faceplate.

    Note: Be sure to have the power supply oriented correctly. The tab must be on the left and click into place when fully seated. If the power supply does not insert easily or does not become flush with the chassis, you may have the power supply upside down.

  7. Attach the power cord to the power supply. If the power supply is correctly installed and functioning normally, the power supply powers up immediately.

    Note: You must have an SFB and a Routing Engine installed in the services gateway for the power supply to turn on automatically.

    Note: If you were moving this power supply from one slot to another, wait at least 60 seconds before inserting it into the new slot.
