Juniper EX8208 User manual

EX8208 Switch Quick Start
To install and configure a Juniper Networks EX8208 Ethernet Switch, you need:
zAdjustable mounting brackets (4 pieces) with 12 screws (provided)
z40–44 mounting screws appropriate for your rack (16 to attach the adjustable
mounting brackets to the rack, 24 to attach the preinstalled front-mounting brackets to
the rack, and 4 if you will attach the optional power cord tray to the rack) (not provided)
zA power cord with a plug appropriate for your geographical location and a power cord
retainer (for each power supply) (provided)
zOptional power cord tray (provided)
zEthernet cable with an RJ-45 connector attached (provided)
zElectrostatic discharge (ESD) grounding strap (provided)
zPhillips (+) screwdrivers (one appropriate for your rack mounting screw size; a number
2 for the adjustable mounting bracket screws; a number 1 to remove power supplies if
you will install the switch without using a mechanical lift) (not provided)
zManagement host, such as a PC, with an Ethernet port (not provided)
NOTE: These instructions apply to four-post 19-in. rack installation. For information
about two-post 19-in. rack installation, more about the tasks described in this quick start,
and about other setup tasks, see the EX Series documentation at
http://www.juniper.net/techpubs/ .
Part 1: Mount the Switch
1. Attach the grounding strap to your bare wrist and to the ESD point on the chassis.
2. Ensure that the rack is properly secured to the building in its permanent location.
3. Install the adjustable mounting brackets in the rack in the lowest position that has
14 U space for the chassis (15 U if you will install the power cord tray).
NOTE: If you are mounting multiple units on the rack, mount the heaviest unit at the
bottom of the rack and mount the others from bottom to top in order of decreasing
weight.
4. (Optional) Attach the power cord tray to the rack.
5. To position the switch in the rack and align the bracket holes with the threaded rack
holes, use a mechanical lift or remove all switch components and have at least three
persons lift the switch and position it.
6. Install a mounting screw into each of the front-mounting bracket holes.
7. If you did not use a mechanical lift, reinstall the switch components.
Part 2: Connect Power to the Switch
Power supplies come preinstalled in the chassis. For each power supply:
1. Ensure that the power supply is fully inserted and latched securely in the chassis.
2. Flip the Enable switch to the Standby position.
3. Squeeze the sides of the power cord retainer clip. Insert the L-shaped clip ends into
the bracket holes on each side of the AC appliance inlet.
4. Insert the coupler end of the power cord into the AC appliance inlet.
5. Push the power cord into the slot in the adjustment nut. Turn the nut until it is against
the base of the coupler and the slot in the nut is turned 90° from the top of the switch.
6. If the AC power source outlet has a power switch, set it to the OFF (0) position.
7. Insert the power cord plug into the power source outlet.
8. If the AC power source outlet has a power switch, set it to the ON (|) position.
9. Verify that the INPUT OK LED on the power supply faceplate is lit and is on steadily.
10. Flip the power supply Enable switch to the “on” position.
Part 3: Perform Initial Configuration
NOTE: Before you begin the configuration, enable a DHCP client on the management
PC you will connect to the switch so that the switch can obtain an IP address
dynamically.
NOTE: Read the following steps before you begin the configuration. You must complete
the initial configuration using EZSetup within 10 minutes. The LCD panel displays a
count-down timer and the switch exits EZSetup after 10 minutes. It then reverts to the
factory default configuration, and the PC loses connectivity to the switch.
1. Transition the switch into initial setup mode using the Menu and Enter buttons to the
right of the LCD panel. To do this:

−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.
2. Connect the Ethernet cable from the Ethernet port on the PC to the MGMT port on
the SRE module that is in slot SRE0.
The interface (the port labeled MGMT on the SRE module in slot SRE0) is now
configured as the DHCP server with the default IP address, 192.168.1.1. The switch
can assign an IP address to the management PC in the range 192.168.1.2 through
192.168.1.253.
3. From the PC, open a Web browser, type http://192.168.1.1 in the address field and
press the Enter key.
4. On the J-Web login page, enter root as the username, leave the password field
blank, and click Login.
5. On the Introduction page, click Next.
6. 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.
7. Click Next.
8. On the Management Options page select Out-of-band Management—Configure
management port to configure the management interface.
9. Click Next.
10. Specify the IP address and default gateway for the management interface.
11. Click Next.
12. On the Manage Access page, you may select options to enable Telnet, SSH, and
SNMP services. For SNMP, you can configure the read community, location, and
contact.
13. Click Next. The Summary page displays the settings you have selected.
14. Click Finish. The configuration is committed as the active switch configuration. You
can now log in with 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.
Safety Warnings Summary
This is a summary of safety warnings. For a complete list of warnings, including
translations, see the EX Series documentation at http://www.juniper.net/techpubs/.
WARNING: Failure to observe these safety warnings can result in personal injury
or death.
zPermit only trained and qualified personnel to install or replace switch components.
zPerform only the procedures described in this quick start and the EX Series
documentation. Other services must be performed only by authorized service
personnel.
zBefore installing the switch, read the planning instructions in the EX Series
documentation to make sure that the site meets power, environmental, and clearance
requirements for the switch.
zBefore connecting the switch to a power source, read the installation instructions in the
EX Series documentation.
zInstalling the EX8208 switch without using a mechanical lift requires at least three
persons to lift the switch onto the adjustable mounting brackets. To prevent injury, keep
your back straight and lift with your legs, not your back.
zIf the rack has stabilizing devices, install them in the rack before mounting or servicing
the switch in the rack.
zBefore installing or after removing an electrical component, always place it
component-side up on an antistatic mat placed on a flat, stable surface or in an
antistatic bag.
zDo not work on the switch or connect or disconnect cables during electrical storms.
zBefore working on equipment that is connected to power lines, remove jewelry,
including rings, necklaces, and watches. Metal objects heat up when connected to
power and ground and can cause serious burns or become welded to the terminals.
zDo not mix AC and DC power supplies in the same chassis.
Power Cable Warning (Japanese)
