Replacing the Switch Fabric Board on the SRX3600 Services Gateway
The SFB is accessible from the front panel, in the topmost slot. It weighs
approximately 5.1 lb (2.3 kg). Before you replace the SFB, you must power off the
services gateway.
To replace an SFB:
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. For more information
about ESD, see Preventing Electrostatic Discharge Damage to the SRX3600
Services Gateway.
2. 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.
3. Place an electrostatic bag or antistatic mat on a flat, stable surface.
4. Disconnect any cables attached to the SFB front panel connectors.
5. Loosen the screws on either end of the SFB front panel.
6. Pull open the ejector handles and slide the SFB halfway out of the chassis.
7. Place one hand underneath the SFB to support it and slide it completely out of
the chassis.
8. Place the SFB on the antistatic mat.

9. Carefully align the sides of the replacement SFB with the guides inside the chassis.
10. Slide the SFB into the chassis until you feel resistance.
11. Grasp both ejector handles and press toward the center of the card to fully seat
the SFB.

12. Tighten the screws on either side of the card.
13. Reconnect the cables, if any, that you disconnected from the SFB front panel
connectors in Step 4.

14. Power on the services gateway by pressing the Power button on the front panel
of the SFB for three to five seconds. Wait for the device to start.
15. Verify that the SFB is functioning normally by checking the LEDs on its faceplate.
The SFB STATUS LED should light steadily green a few minutes after the device
is powered on. If the SFB STATUS LED is red, remove and install the SFB again.
If the SFB STATUS LED still lights steadily red, the SFB is not functioning properly.
