Replacing an I/O Card on the SRX3400 Services Gateway
I/O cards (IOCs) are installed in the services gateway in slots labeled labeled
CFM1-CFM4. Before you replace an IOC, you must power off the services gateway.
SFPs and XFPs are hot-insertable and hot-removable. Removing an SFP or XFP
transceiver does not interrupt IOC functioning, but the removed transceiver no longer
receives or transmits data.
NOTE: We strongly recommend the use of Juniper Networks SFP and XFP transceivers.
We cannot guarantee correct operation if other transceivers are used. The transceiver
type can be different in each port, as long as a supported part number is used.
To replace an 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 SRX3400
Services Gateway.
3. If you have not already done so, power off the device by pressing the Power
button on the front panel of the Switch Fabric Board (SFB) for three to five
seconds.
The PWR LED blinks to show you that the device is shutting down. Wait for the
device to shut down before proceeding.
4. Disconnect any cables connected to the Ethernet ports, marking them so they
can be reconnected in the proper location. If the 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 faceplate.
6. Pull open the ejector handles to unseat the IOC.
7. Grasp the IOC by the ejector handles and slide it halfway out of the chassis.
8. Place one hand underneath the IOC to support it and slide it completely out of
the chassis.

9. Place the IOC on the antistatic mat. If you are not reinstalling an 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 and XFP Transceivers
on I/O Cards on the SRX3400 Services Gateway; otherwise, continue with step
10.
10. Carefully align the sides of the replacement IOC with the guides inside the chassis.
11. Slide the IOC into the slot until you feel resistance, and then press the IOC's
faceplate until it engages the connectors.
12. Press both of the ejector handles inward to seat the IOC.
13. Tighten the captive screws on the left and right of the IOC faceplate.

14. If the 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.
15. Insert the appropriate cables into the cable connector ports on each 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.
16. Power on the services gateway, as described in Powering On the SRX3400
Services Gateway. The OK/FAIL LED on the IOC faceplate should blink green,
then light steadily.
NOTE: If the OK/FAIL LED is red, remove and reinstall the IOC. If the OK/FAIL LED
remains red, the 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 IOCs or other CFM cards. The handles might come off, causing the chassis to
drop and inflicting possible grave injury.
