Replacing SRX5600 Services Gateway Port Modules

To replace a port module, perform the following procedures:

1. Removing an SRX5600 Services Gateway Port Module
2. Installing an SRX5600 Services Gateway Port Module

Removing an SRX5600 Services Gateway Port Module

Port modules are installed in Flex IOCs in the services gateway card cage. A port module weighs up to 3 lb (1.4 kg). Be prepared to accept its full weight when you remove or install a port module.

To remove a port module (see Figure 1):

1. Have ready a replacement port module or blank panel and an antistatic mat for the port module. Also have ready rubber safety caps for each port on the port module you are removing that uses an optical interface.
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.
3. Label the cables connected to each port on the port module so that you can later reconnect the cables to the correct ports.
4. Use one of the following methods to take the port module offline:
   • Insert a pointed tool into the ONLINE pinhole on the front panel of the port module to press the button behind it. Hold the button down until the OK/FAIL LED goes off.
   • Issue the following CLI command:
     user@host>request chassis fpc-slot slot-number pic-slot slot-number offline

     For more information about the command, see the Junos OS System Basics and Services Command Reference.

5. Disconnect the cables from the port module. If the port module 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.

6. Loosen the captive screws that retain the port module in its slot in the Flex IOC.
7. Grasp the captive screws and slide the port module straight out of the Flex IOC halfway.
8. Place one hand around the front of the port module and the other hand under it to support it. Slide the port module completely out of the Flex IOC, and place it on the antistatic mat or in the electrostatic bag.

9. If you are not reinstalling a port module into the empty slot within a short time, install a blank panel over the slot to maintain proper airflow in the card cage.

   Caution: After removing a port module from the chassis, wait at least 30 seconds before reinserting it, removing a port module from a different slot, or inserting a port module into a different slot.

Installing an SRX5600 Services Gateway Port Module

To install a port module into a Flex IOC (see Figure 2):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. If you have not already done so, install the Flex IOC in which you are installing the port module.
3. Place the port module on an antistatic mat or remove it from its electrostatic bag.
4. Verify that each fiber-optic transceiver is covered with a rubber safety cap. If it is not, cover the transceiver with a safety cap.
5. If necessary, remove the blank panel covering the slot in the Flex IOC where you are installing the port module.
6. Orient the port module so that the faceplate faces you.
7. Lift the port module into place and carefully align the right and left edges of the port module with the guides inside the Flex IOC.
8. Slide the port module all the way into the Flex IOC until it is fully seated.
9. Tighten both captive screws to secure the port module in the Flex IOC.

10. If the port module uses fiber-optic interfaces, 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.

11. Insert the appropriate cables into the cable connector ports on each port module. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop, using the cable management system. Placing fasteners on a loop helps to maintain its shape.

    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.

12. Use one of the following methods to take the port module online:
    • Insert a pointed tool into the ONLINE pinhole on the front panel of the port module to press the button behind it. Hold the button down until the OK/FAIL LED at the opposite end of the front panel lights green steadily, in about 5 seconds.
    • Issue the following CLI command:
      user@host>request chassis fpc-slot slot-number pic-slot slot-number online

      For more information about the command, see the Junos OS System Basics and Services Command Reference.

    Caution: After the OK/FAIL LED turns green, wait at least 30 seconds before removing the port module again, removing a port module from a different slot, or inserting a port module in a different slot.

You can also verify that the port module is functioning correctly by issuing the show chassis fpc and show chassis fpc pic-status commands.
