Juniper EX4550 User manual

EX4550 Switch Quick Start
See the complete EX Series documentation at http://www.juniper.net/techpubs/ .
To install and perform initial configuration of a Juniper Networks EX4550 Ethernet
Switch, you need:
zTwo mounting brackets and eight mounting screws (provided)
zScrews to secure the chassis to the rack or cabinet (not provided)
zPhillips (+) screwdriver, number 2 (not provided)
zFor AC systems—an AC power supply and an AC power cord with a plug appropriate
for your geographical location—both provided
zFor DC systems—A DC power supply (provided) and DC power source cables (14–16
AWG—not provided) with ring lugs (Molex 190700069 or equivalent—not provided)
attached
zFor grounding the switch—a grounding cable (minimum 14 AWG (2 mm²), minimum
90°C wire), a grounding lug (Panduit LCD6-14BH-L or equivalent), a pair of
10-32x.25-in. screws, and a pair of flat washers—none provided
zEthernet cable with an RJ-45 connector attached (provided)
zRJ-45 to DB-9 serial port adapter (provided)
zManagement host, such as a PC, with an Ethernet port (not provided)
Part 1: Mount the Switch on Two Posts of a Rack
Two people are required for this procedure.
1. Place the rack or cabinet in its permanent location, allowing adequate clearance for
airflow and maintenance, and secure it to the building structure.
NOTE: While mounting multiple units on a rack, mount the heaviest unit at the bottom
and mount the other units from the bottom to the top in decreasing weight order.
2. Position the mounting brackets along the side panels of the chassis aligning them
with the LCD panel side, the power supply side, or with the center of the side panels
depending on how do you want to mount the switch.
3. Attach the brackets to the chassis with the mounting screws. Tighten the screws.
NOTE: The switch with one power supply installed in it weighs approximately 19.4 lb (8.8
kg). Installing the switch requires one person to lift it and a second person to secure it to
the rack.
4. 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 rail, making sure
the chassis is level.
5. Have the second person secure the switch to the rack by using the appropriate
screws. Tighten the screws.
Part 2: Connect Power to the Switch
NOTE: Grounding is required for DC systems and recommended for AC systems. An
AC-powered switch gets additional grounding when you plug the power supply in the
switch into a grounded AC power outlet using the power cord.
To connect power to an AC-powered switch:
1. Insert the coupler end of the power cord into the AC power cord inlet on the AC
power supply faceplate.
2. Push the power cord retainer onto the power cord.
3. If the AC power source outlet has a power switch, set it to the OFF (0) position.
4. Insert the power cord plug into the power source outlet.
5. If the AC power source outlet has a power switch, set it to the ON (|) position.
6. Verify that the AC and the DC LEDs are lit green and on steadily.
To connect power to a DC-powered switch:
The DC power supply has four terminals labeled V+, V+, V–, and V– for connecting DC
power source cables labeled positive (+) and negative (–).
WARNING: Ensure that the input circuit breaker is open so that the cable leads will
not become active while you are connecting DC power.
1. Connect one end of the grounding cable to a proper earth ground.
CAUTION: A licensed electrician must attach the lug to the grounding cable.
2. Secure the grounding lug over the earthing terminal (located on the left side of the
chassis) with washers and screws using the Phillips (+) screwdriver, number 2.
3. Remove the terminal block cover. The terminal block cover is a piece of clear plastic
that snaps into place over the terminal block.
4. Remove the screws on the terminals using the screwdriver. Save the screws.
5. Connect each power supply to the power
sources. Secure power source cables to the
power supplies by screwing the ring lugs
attached to the cables to the appropriate
terminals by using the screw from the
terminals.
−Secure the ring lug of the positive (+) DC
power source cable to the V+ terminal on
the DC power supply.
−Secure the ring lug of the negative (–) DC
power source cable to the V– terminal on the DC power supply.
−Tighten the screws on the power supply terminals using the screwdriver. Do not
overtighten—apply between 5 in-lb (0.56 Nm) and 6 in-lb (0.68 Nm) of torque to
the screws.

6. Replace the terminal block cover.
7. Close the input circuit breaker.
8. Verify that the IN and the OUT LEDs are lit green and on steadily.
Part 3: Perform Initial Configuration on a Standalone Switch
NOTE: To run the ezsetup script, the switch must have the factory default configuration
as the active configuration. If you have configured anything on the switch and want to run
ezsetup, see the EX Series documentation at http://www.juniper.net/techpubs/ to revert
to the factory default configuration.
To connect and configure the switch from the console:
1. Set the values in the console server or PC: baud rate—9600; flow control—none;
data—8; parity—none; stop bits—1; DCD state—disregard.
2. Connect the console port of the switch to a laptop or PC using the RJ-45 to DB-9
serial port adapter.
NOTE: You can also use the mini-USB port to connect an EX4550 switch to a laptop or
PC (see the EX Series documentation at http://www.juniper.net/techpubs/) .
3. At the Junos OS shell prompt root%, type ezsetup.
4. (Optional) Enter the hostname.
5. Enter the root password you want to use for this device. You are prompted to re-enter
the root password.
6. Enter yes to enable services like Telnet and SSH. By default, Telnet is not enabled
and SSH is enabled.
NOTE: You will not be able to log in to the switch as the user root through Telnet. Root
login is only allowed through SSH.
7. Use the Management Options page to select the management scenario:
−In-band Management—Use VLAN ‘default’ for management
−In-band Management—Create new VLAN for management
Select this option to create a management VLAN. Specify the VLAN name, VLAN
ID, management IP address, and default gateway for the new VLAN. Select the
ports that must be part of this VLAN.
−Out-of-band Management—Configure management port
Select this option to configure only the management interface. Specify the IP
address and default gateway for the management interface.
8. (Optional) Specify the SNMP Read Community, Location, and Contact to configure
SNMP parameters.
9. (Optional) Specify the system date and time. Select the time zone from the list.
10. The configured parameters are displayed. Enter yes to commit the configuration. The
configuration is committed as the active configuration for the switch.
You can now log in with the CLI to continue configuring the switch.
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 an EX4550 switch requires one person to lift the switch and a second person
to install the mounting screws.
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.
