Replacing the SFB on the SRX3400 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:

Attach an 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

If you have not already done so, power off the services gateway by pressing the Power
button on the front panel of the SFB for three to five seconds.
The

LED blinks to show you that the services gateway is shutting down. Wait for
the services gateway to shut down before you proceed to the next step.
