Replacing SRX5800 Services Gateway Flex IOCs

To replace a Flex IOC, perform the following procedures:

1. Removing an SRX5800 Services Gateway Flex IOC
2. Installing an SRX5800 Services Gateway Flex IOC

Removing an SRX5800 Services Gateway Flex IOC

A Flex IOC weighs up to 13.1 lb (5.9 kg). Be prepared to accept the full weight of the card as you remove it.

To remove a Flex IOC (see Figure 1):

1. Have ready a replacement card or blank panel and an antistatic mat for the Flex IOC.
2. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3. Use one of the following methods to take the Flex IOC offline:
   • Press and hold the corresponding online button on the craft interface. The green OK LED next to the button begins to blink. Hold the button down until the LED goes off.
   • Issue the following CLI command:
     user@host>request chassis fpc slot slot-number offline

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

4. If you have not already done so, remove the port modules installed in the Flex IOC.
5. Simultaneously turn both of the ejector handles counterclockwise to unseat the Flex IOC.
6. Grasp the handles and slide the Flex IOC straight out of the card cage halfway.
7. Place one hand around the front of the Flex IOC and the other hand under it to support it. Slide the Flex IOC completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.

   Caution: The weight of the Flex IOC is concentrated in the back end. Be prepared to accept the full weight—up to 13.1 lb (5.9 kg)—as you slide the Flex IOC out of the chassis. When the Flex IOC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight. Do not stack Flex IOCs on top of one another after removal. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.

8. If you are not reinstalling a replacement card 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 an IOC from the chassis, wait at least 30 seconds before reinserting it, removing an IOC from a different slot, or inserting an IOC into a different slot.

Installing an SRX5800 Services Gateway Flex IOC

Note: Your services gateway must be running Junos version 9.5R1 or later in order to recognize Flex IOCs and port modules.

To install a Flex IOC (see Figure 2):

1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. Place the Flex IOC on an antistatic mat or remove it from its electrostatic bag.
3. Identify the slot on the services gateway where you will install the Flex IOC.
4. If you have not already done so, remove the blank panel from the slot where you are installing the Flex IOC.
5. Orient the Flex IOC so that the faceplate faces you, the text on the card is right-side up, and the EMI strip is on the right-hand side.
6. Lift the Flex IOC into place and carefully align first the bottom and then the top of the card with the guides inside the card cage.
7. Slide the Flex IOC all the way into the card cage until you feel resistance.

8. Grasp both ejector handles and rotate them clockwise simultaneously until the Flex IOC is fully seated.
9. Use one of the following methods to bring the Flex IOC online:
   • Press and hold the corresponding online button on the craft interface until the green OK LED next to the button lights steadily, in about 5 seconds.
   • Issue the following CLI command:
     user@host>request chassis fpc slot slot-number online

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

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