Juniper EX4500 Quick Start Manual

EX4500 Switch Quick Start
See the complete EX Series documentation at http://www.juniper.net/techpubs/ .
To install and configure a Juniper Networks EX4500 Ethernet Switch, you need:
Two mounting brackets and 20 mounting screws (provided)
–
For AC systems an AC power supply (provided), a power cord with a plug appropriate
for your geographical location (provided), and a power cord retainer (provided)
–
For DC systems a DC power supply (provided)
provided) with the cable lugs (Molex 190410014 or equivalent
attached
Ethernet cable with an RJ-45 connector attached (provided)
Management host, such as a PC, with an Ethernet port (not provided)
Screws to secure the chassis to the rack or cabinet (not provided)
Phillips (+) screwdriver, number 2 (not provided)
Part 1: Install a Power Supply in the Switch (If It Is Not Installed)
1. Ensure that you have the correct power supply. The color of the power supply's
ejector lever must match that of the intake or exhaust labels visible through the fan
tray vents.
CAUTION: Operating the switch with an incorrect power supply might cause the
chassis to overheat.
2. Taking care not to touch power supply pins, leads, or solder connections remove the
power supply from the bag.
3. Using both hands, place the power supply in the power supply slot on the rear panel
of the switch and slide it in until it is fully seated.
Part 2: Mount the Switch
These instructions describe mounting the switch on a two-post 19-in. rack. See the EX
Series documentation at http://www.juniper.net/techpubs/ for information about using a
four-post rack.
1. Place the rack in its permanent location, allowing adequate clearance for airflow and
maintenance, and secure it to the building structure.
NOTE: If you are mounting multiple units on the rack, mount the heaviest unit at the
bottom and mount the others from bottom to top in order of decreasing weight.
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.
3. Attach the mounting brackets to the chassis by using the mounting screws.
NOTE: The switch weighs 37 lb (17 kg). Installing the switch requires one person to lift it
and a second person to secure it to the rack.
4. Have one person 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 the chassis is level.
5. Have the second person secure the switch to the rack by using the appropriate
screws. Tighten the screws.

Part 3: Connect Power to the Switch
To connect AC power to the 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 retainer clip toward the cord until the cord slides into the slot in the
adjustment nut. Turn the nut until it is tight 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.
To connect DC power to the switch:
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. Remove the plastic cover from the DC power input terminal block by sliding it off
either to the left or right.
2. Remove the locking screws from each DC power input terminal, using the
screwdriver.
3. Install the negative (-) power cable with lug attached on the -48V DC power input
terminal, securing it with the locking screw. Tighten the locking screw.
4. Install the positive (+) power cable with lug attached on the RTN DC power input
terminal, securing it with the locking screw. Tighten the locking screw.
5. Slide the plastic cover over the input terminal block.
6. Close the input circuit breaker. Verify that the LED on the power supply is lit green
and on steadily.
7. Repeat these steps for each DC power supply.
Part 4: Perform Initial Configuration on a Standalone Switch
NOTE: Before you begin the configuration, enable a DHCP client on the management
PC you will connect to the switch so that the PC can obtain an IP address dynamically.
