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.

the SFB.
