Connect the Grounding Cable
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist,
and connect the strap to the ESD point on the chassis.
2. Connect one end of the grounding cable to a proper earth ground, such as the
rack in which the services gateway is mounted.
3. Place the grounding cable lug over the grounding point on the rear of the
chassis.

NOTE: The device should be permanently connected to ground during
normal operation. A licensed electrician must attach a cable lug to the
grounding cable. A cable with an incorrectly attached lug can damage
the device.
4. Secure the grounding cable lug to the grounding point with the screw.
Power On the Device
1. If you are using the AC model, perform the following steps:
a. Insert the coupler end of the power cord into the AC power cord inlet on
the AC power supply faceplate. Push the power cord retainer onto the
power cord.

0
b. Insert the power cord plug into an AC power source outlet.
c. Turn on the power to the AC power receptacle.
d. Repeat steps a through c for the second AC power supply.
e. Verify that the AC and DC LEDs on each power supply are lit green.
2. If you are using the DC model, perform the following steps:
WARNING: Before performing the following procedure, ensure that
there is no power in the DC circuit. To ensure that all power is cut o,
locate the circuit breaker on the panel board that services the DC circuit,
switch the circuit breaker to the OFF (0) position, and tape the switch
handle of the circuit breaker in the OFF position.
a. Ensure that the voltage across the DC power source cable leads is 0 V and
that the cable leads do not become active while you are connecting DC
power.

b. Verify that the DC power cables are correctly labeled before making
connections to the power supply. In a typical power distribution scheme
where the return is connected to chassis ground at the battery plant, you
can use a multimeter to verify the resistance of the -48V and RTN DC
cables to chassis ground:
•The cable with very high resistance (indicating an open circuit) to chassis
ground will be connected to the V- (input) DC power input terminal.
•The cable with very low resistance (indicating a closed circuit) to chassis
ground will be connected to the V+ (return) DC power input terminal.
c. Remove the clear plastic cover from the terminal studs on the faceplate.
d. Remove the screws on the terminals by using a Phillips (+) screwdriver,
number 2.
e. Secure each positive (+) DC source power cable lug to a RTN (return)
terminal. Secure each negative (–) DC source power cable lug to a -48V
(input) terminal.
f. Tighten the screws on the power supply terminals until snug using the
screwdriver. Do not overtighten.

g. Replace the clear plastic cover over the terminal studs on the faceplate.
h. Remove the tape from the switch handle of the circuit breaker on the panel
board that services the DC circuit, and switch the circuit breaker to the ON
(|) position.
i. Verify that the IN and OUT LEDs on the power supply are lit green and are
on steadily.
3. Wait until the Status LED on the front panel of the services gateway is solid
green before proceeding to the next step.

Connect to the Console Port
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist,
and connect the strap to the ESD point on the chassis.
2. Plug the RJ-45 end of the DB9-to-RJ-45 cable into the Console port on your
services gateway.

3. Connect the other end of the cable to the serial port on the management
device. Use the following values to configure the serial port:
Baud rate—9600; Parity—N; Data bits—8; Stop bits—1; Flow control—None.

Configure Root Authentication
Before you can use J-Web to configure your device, you must access the CLI to
configure root authentication.
1. Log in to the device as root. When the device is powered on with the factory-
default configuration, you do not need to enter a password.
2. At the (%) prompt, type cli to start the CLI and press Enter. The prompt
changes to an angle bracket (>) when you enter the CLI operational mode.
root%cli
root>
3. At the (>) prompt, type configure and press Enter. The prompt changes from
> to # when you enter configuration mode.
root> congure
Entering conguration mode
[edit]
root#
4. Set the root authentication password by entering a cleartext password, an
encrypted password, or an SSH public key string (DSA or RSA).
root# set system root-authentication plain-text-
password
New password: password
Retype new password: password
5. Configure the route for the management interface (optional, required only if
you do not connect the MGMT port directly to the management device).
root# set routing-options static route <destination
prex> next-hop <gateway>
6. Commit the configuration changes.
root# commit
7. Connect the MGMT port on the device to the Ethernet port on the
management device using an RJ-45 cable.
8. Configure an IP address on the 192.168.1.0/24 subnetwork for the
management device. By default, the management interface is configured with
the 192.168.1.1/24 IP address. If you need to change the IP address, perform
the following steps or else proceed to Step 9.
a. Delete the default management interface IP address.
root# delete interface fxp0 unit 0 family inet
address 192.168.1.1/24
b. Configure a new IP address for the management interface.
root# set interfaces fxp0 unit 0 family inet address
address/prex-length
c. Commit the configuration changes.
root# commit
d. Configure an IP address for the management device. Ensure that the IP
address is on the same subnetwork as the management interface (fxp0).
9. Launch a Web browser from the management device and access the services
gateway using the URL https://192.168.1.1.
If you changed the management interface IP address in Step 8, then use the
URL https://<management IP address> to access the services gateway.
NOTE: As the system-generated certificate is not trusted by default, an
alert is displayed. You can ignore this alert and proceed to access the
services gateway.
The J-Web login page is displayed. This indicates that you have successfully
completed the initial configuration and that your SRX4100 Services Gateway
is ready for use.

10. Log in as root and proceed with configuring the settings based on your
requirements.
Power O the Device
To power o the device, press the Power switch on the rear of the device. After
powering o the device, wait at least 60 seconds before turning it back on.
Reset the Configuration
Pressing and holding the RESET button for 5 seconds or more deletes all
configurations (backup configurations and rescue configuration) on the device,
and loads and commits the factory configuration.
