Connecting and Configuring the J-SRX240 Services Gateway
Use the instructions below to connect and set up any model of the J-SRX240 Services
Gateway to protect your network. Refer to the LEDs on the front panel of the device to
help you determine the status of the device.
Part 1: Connect the Services Gateway to Earth Ground
1. Obtain a grounding cable—14 AWG single-strand, 4 A—with a ring-type,
vinyl-insulated TV14-6R lug or equivalent attached by a licensed electrician.
2. Connect the grounding cable to a proper earth ground.
3. Place the grounding cable lug over the grounding point on the upper rear of the
chassis, and secure the lug with one 6-32 UNC screw.

Part 2: Connect the Power Cable to the Device
Connect the power cable to the device and a power source. We recommend using a
surge protector. Note the following indications:
POWER LED (green): The device is receiving power.
STATUS LED (green): The device is operating normally.
ALARM LED (amber): The device is operating normally, and may glow amber as a
rescue configuration has not been set. This is not a panic condition.
mPIM LED (off): The Mini-Physical Interface Module (Mini-PIM) is not present or is
not detected by the device. If this LED is green and steadily on, it indicates that the
Mini-PIM is functioning normally.
After a rescue configuration has been set, an amber ALARM LED indicates a
NOTE:
minor alarm, and a solid red ALARM LED indicates that a major problem exists on the
services gateway.
You must allow the device between 5 and 7 minutes to boot up after you have
NOTE:
powered it on. Wait until the STATUS LED is solid green before proceeding to the next
part.
Part 3: Connect the Management Device
Connect the management device to the services gateway using either of the following
methods:
Connect an RJ-45 cable (Ethernet cable) from any one port between ge-0/0/1 and
ge-0/0/15 on the front panel to the Ethernet port on the management device
(workstation or laptop).
We recommend this connection method. If you are using this method to connect,
proceed with Part 4.
Connect an RJ-45 cable (Ethernet cable) from the port labeled CONSOLE to the
supplied DB-9 adapter, which then connects to the serial port on the management
device. (Serial port settings: 9600 8-N-1.)
If you are using this method to connect, proceed with the CLI configuration
instructions available in the Branch SRX Series Services Gateways Golden
