Removing an SRX5800 Services Gateway IOC
An IOC weighs up to 13.1 lb (5.9 kg). Be prepared to accept its full weight.
To remove an IOC (see Figure 1):
- Have ready a replacement IOC or IOC blank panel and an antistatic mat for the IOC. Also have ready rubber safety caps for each optical interface on the IOC you are removing.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Label the cables connected to each port on the IOC so that you can later reconnect the cables to the correct ports.
- Use one of the following methods to take the IOC
offline:
- Press and hold the corresponding IOC 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 offlineFor more information about the command, see the JUNOS System Basics and Services Command Reference.
- Disconnect the cables from the IOC.

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.
- Immediately cover each optical transceivers and the end of each fiber-optic cable with a rubber safety cap.
- Arrange the disconnected cables in the cable manager to prevent the cables from developing stress points.
- Simultaneously turn both of the ejector handles counterclockwise to unseat the IOC.
- Grasp the handles and slide the IOC straight out of the card cage halfway.
- Place one hand around the front of the IOC and
the other hand under it to support it. Slide the IOC completely out
of the chassis, and place it on the antistatic mat or in the electrostatic
bag.

Caution: The weight of the 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 IOC out of the chassis.
When the 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 IOC 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.
- If you are not reinstalling an IOC into the empy slot
within a short time, install a blank IOC 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.
