EX6210 Switch Quick Start
Part 2: Install a Power Supply in the Switch (If It Is Not Installed)
1. Taking care not to touch power supply pins, leads, or solder connections, remove the
power supply from the bag.
2. Flip the Enable switch on the power supply to the Standby position.
Part 3: 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 AC power to the switch:
1. Squeeze the sides of the power cord retainer clip and insert the L-shaped ends of the
clip into the holes in the bracket on the top and bottom 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.

Part 1: 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. Two people, minimum, are needed to install the switch without a lift.
1. Place the rack in its permanent location, allowing adequate clearance for airflow and
maintenance, and secure it to the building structure.
2. Attach the grounding strap to your bare wrist and to the ESD point on the chassis.
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 decreasing weight order.
3. Identify 14 U of space for the chassis in the rack.
4. Position the switch in the rack and align the mounting bracket holes with threaded
rack holes either by using a mechanical lift or by removing all components and having
at least two persons lift the switch and position it.
5. Align the bottom hole in each mounting bracket with a hole in each rack rail, making
sure the chassis is level.
6. Install mounting screws in all front-mounting bracket holes and tighten them.
7. If you did not use a mechanical lift, reinstall the switch components.
3. Using both hands, place the power supply in the power supply slot on the front
bottom of the switch, and slide it in until it is fully seated.
4. Push the two captive screws on the front top of the power supply into the power
supply faceplate, so the screws are seated inside the corresponding holes on the
chassis.
5. Tighten the screws by turning them clockwise using the Phillips (+) screwdriver,
number 1. Do not overtighten the screws. Applying excessive force might damage
the screws or power supply. When the screws are tight enough, the power supply
locks into the chassis.
6. Repeat these steps for all remaining power supplies.

z RJ-45 to DB-9 serial port adapter (provided)
z Phillips (+) screwdrivers (one matching rack-mounting screw size; number 1 if
installing a power supply; numbers 1 and 2 if not using a mechanical lift; number 2 if
connecting DC power and installing grounding lug) (not provided)
z 3/8-in. (9.5-mm) nut driver or socket wrench if connecting DC power (not provided)
z Management host, such as a PC, with an Ethernet port (not provided)
If the AC power source outlet has a power switch, set it to the OFF (0) position.
Insert the power cord plug into the power source outlet.
If the AC power source outlet has a power switch, set it to the ON (|) position.
Verify that the INPUT OK LED on the power supply faceplate is lit and is on steadily.
Flip the Enable switch to the On position.
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. Connect one end of the grounding cable to a proper earth ground.
CAUTION: A licensed electrician must attach the lug to the grounding cable.
7. Replace the plastic cover on the input terminal block and tighten the screw clockwise.
Do not overtighten the screw.
8. Close the input circuit breaker. Verify that the INPUT LED on the power supply is lit
green and on steadily.
9. Repeat these steps for each DC power supply.
Part 4: Perform Initial Configuration
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
