Mount the Switch
You can mount the switch on two posts of a 19-in. rack or cabinet by using the mounting brackets provided with the
switch.
1. Ensure that the rack is properly secured to the building in its permanent location.
NOTE: If you are mounting multiple units on a rack, mount the heaviest unit at the bottom and mount the
others from bottom to top in decreasing order of the weight of the units.
2. Align the mounting brackets along the front or rear of the side panels of the chassis depending on whether you are
front-mounting or rear-mounting the switch, and attach the mounting brackets to the chassis by using the mounting
screws. Tighten the screws.
NOTE: The switch weighs 18 lb (8.2 kg). Installing the switch requires one person to lift the switch and a
second person to secure it to the rack.
3. Have one person grasp both sides of the switch, lift the switch, and position it in the rack, aligning the mounting bracket
holes with the threaded holes in the rack rail. Align the bottom hole in each mounting bracket with a hole in each rack
rail, making sure that the chassis is level.
4. Have a second person secure the switch to the rack or cabinet by using appropriate screws.

Connecting EX3200 and EX4200 to AC power
To connect power to an AC-powered switch:
1. Squeeze the two sides of the power cord retainer clip and insert the L-shaped ends of the wire clip into the holes in
the bracket on each side of the AC appliance inlet.
2. Insert the coupler end of the power cord into the AC appliance inlet.
3. Push the power cord into the slot in the adjustment nut of the power cord retainer clip. Turn the nut until it is snug
against the base of the coupler and the slot in the nut is turned 90° from the top of the switch.
4. If the AC power source outlet has a power switch, set it to the OFF (0) position.
5. Insert the power cord plug into the power source outlet.
6. If the AC power source outlet has a power switch, set it to the ON (|) position.
7. Repeat these steps for each AC power supply.

Connecting EX3200 and EX4200 to DC power
To connect power to a DC-powered switch:
Each DC power supply has four terminals labeled A+, B+, A–, and B–. The power supply is shipped with jumpers from the
A+ input to the B+ input tied together and jumpers from the A– input to the B– input tied together.
CAUTION: Ensure that you install the power supply module first and then install the DC input wire,
before closing input breaker ON.
WARNING: Ensure that the input circuit breaker is open so that the voltage across the DC power
source cable leads is 0 V and that the cable leads will not become active while you are connecting DC
power. Remove the screw that secures the terminal block cover and remove the cover.
1. Connect the power supply to the power sources. Secure power source cables to the power supply by screwing the
ring lug attached to the cable to the appropriate terminal (use the screw from the terminal).
•To connect a power supply to a power source: Leave the jumpers in place and secure the positive power source
cable to the A+ terminal and the negative power source cable to the A– terminal.
•To connect one power supply to two power sources: Remove the jumpers and secure the positive power source
cable of the first power source to the A+ terminal and the negative power source cable to the A– terminal. Then
secure the positive power source cable of the second power source to the B+ terminal and the negative power source
cable to the B– terminal.
2. Replace the terminal block cover and secure it by using the screw.
3. Close the input circuit breaker. Verify that the LEDs on the power supply are lit green and are on steadily.
4. Repeat these steps for each DC power supply.

Step 2: Up and Running
NOTE: Before you begin the configuration, enable a DHCP client on the management PC that you connect to
the switch so that the switch can obtain an IP address dynamically.
NOTE: Read the following steps before you begin the configuration. Complete the initial configuration within
10 minutes by using EZSetup. The LCD panel displays a countdown timer when the switch is in initial setup
mode. The switch exits EZSetup after 10 minutes and reverts to the factory configuration, and the PC loses
connectivity to the switch.
1. Transition the switch into EZSetup mode by using the Menu and Enter buttons located to the right of the LCD panel:
•Press Menu until you see MAINTENANCE MENU. Then press Enter.
•Press Menu until you see ENTER EZSetup. Then press Enter.
If EZSetup does not appear as an option in the menu, select Factory Default to return the switch to the factory default
configuration. EZSetup is displayed in the menu only when the switch is set to the factory default configuration.
•Press Enter to confirm setup and continue with EZSetup.
Connect the Ethernet cable from the Ethernet port on the PC to port 0 (ge-0/0/0) on the front panel of the switch.The
ge-0/0/0 interface is now configured as a DHCP server with the default IP address, 192.168.1.1. The switch can assign
an IP address to the management PC in the IP address range 192.168.1.2 through 192.168.1.253.
2. From the PC, open a Web browser, type http://192.168.1.1 in the address field, and press the Enter key.
3. On the J-Web login page, enter root as the username, leave the Password field blank, and click Login.
4. On the Introduction page, click Next.
5. On the Basic Settings page, enter the hostname, enter and reenter a password, specify the time zone, and synchronize
the switch date and time settings with the management PC or set them manually. Then, click Next.
6. Use the Management Options page to select the management scenario:
•In-band Management—Use VLAN ‘default’ for management
Select this option to configure all data interfaces as members of the default VLAN. Click Next. Specify the management
IP address and the default gateway.
•In-band Management—Create new VLAN for management
Select this option to create a management VLAN. Click Next. Specify the VLAN name, VLAN ID, member interfaces,
and management IP address and default gateway for the new VLAN.
7

•Out-of-band Management—Configure management port
Select this option to configure only the management interface. Click Next. Specify the IP address and default gateway
for the management interface.
7. Click Next.
8. On the Manage Access page, you can select options to enable Telnet, SSH, and SNMP. For SNMP, you can configure
the read community, location, and contact.
9. Click Next. The Summary page displays the settings you have selected.
10. Click Finish. The configuration is committed as the active switch configuration. You can now log in by using the CLI or
the J-Web interface to continue configuring the switch.
NOTE: After the configuration is committed, the connectivity between the PC and the switch might be lost. To
reconnect, release and renew the IP address by executing the appropriate commands on the PC or by removing
and reinserting the Ethernet cable.
