Replacing an IOC or NP-IOC on the SRX1400 Services Gateway

 

IOCs or NP-IOCs are installed in the services gateway in the CFM slot labeled 2.

To replace an IOC or NP-IOC:

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
  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 SRX1400 Services Gateway.
  3. Power off the services gateway.

    To power off the services gateway, press the Power button on the front panel of the System I/O Card (SYSIOC) for three to five seconds.

    The PWR LED blinks to show you that the services gateway is shutting down.

  4. Disconnect any cables connected to the Ethernet ports, marking them so they can be reconnected in the proper location. If the IOC or NP-IOC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap. Arrange the disconnected cables in the cable management system to prevent the cables from developing stress points.Warning

    Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

    Caution

    Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

    Caution

    Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

  5. Loosen the captive screws at each end of the IOC or NP-IOC faceplate.
  6. Grasp the IOC or NP-IOC by its handle and slide it halfway out of the chassis. See Figure 1.

  7. Place one hand underneath the IOC or NP-IOC to support it and slide it completely out of the chassis.
  8. Place the IOC or NP-IOC on the antistatic mat. If you are not reinstalling an IOC or NP-IOC into the emptied slot within 30 minutes, install a blank panel over the slot to maintain proper airflow in the card cage.

    If you need to replace the transceivers, see Replacing SFP, SFP+, and XFP Transceivers on the SRX1400 Services Gateway; otherwise, continue with step 10.

  9. Carefully align the sides of the replacement IOC or NP-IOC with the guides inside the chassis.
  10. Slide the IOC into the slot until you feel resistance, and then press the IOC or NP-IOC faceplate until it engages the connectors.
  11. Tighten the captive screws on the left and right of the IOC or NP-IOC faceplate. See Figure 2.

  12. If the IOC or NP-IOC uses fiber-optic cable, remove the rubber safety cap from each transceiver and cable.Warning

    Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

  13. Insert the appropriate cables into the cable connector ports on each IOC or NP-IOC. Caution

    Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

    Caution

    Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

  14. Power on the services gateway, as described in Powering On the SRX1400 Services Gateway.
  15. Check the OK/FAIL LED on the new IOC or NP-IOC. The OK/FAIL LED on the CFM faceplate should blink green, then light steadily. If it is red, remove and reinstall the IOC or NP-IOC. If the OK/FAIL LED remains red, the IOC or NP-IOC is not functioning properly. Contact your customer support representative.
Warning

Never lift the services gateway using the handles on the front panels of the IOC or NP-IOC. The handles might come off, causing the chassis to drop and inflicting possible grave injury.
