Dell PowerConnect J-Series J-EX4500 Ethernet Switch Quick Start

To install and configure a Dell PowerConnect J-Series J-EX4500 Ethernet Switch

(regulatory model number EX4500) on a two-post 19-inch rack or cabinet, you need:

zTwo mounting brackets and 20 mounting screws (provided)

zA Phillips (+) screwdriver, number 2

z8 rack-mount screws—and 8 cage nuts and washers if your rack requires them—of the

appropriate size and type to secure the chassis to your rack or cabinet (provided)

zA flat-blade (-) screwdriver if you are installing the switch in a rack with square,

nonthreaded holes

zA jumper cable and cord retainer for each power supply (provided)

zFor Virtual Chassis connection, one or more Virtual Chassis cables and cable

connector retainers

zA grounding cable—14 AWG (2 mm²), minimum 90°C wire—with appropriate

grounding lug attached by a licensed electrician, for grounding points 0.625 in.

(15.86 mm) apart

zTwo 10-32 x.1/4-in. screws with split washers to secure the grounding lug to the switch

zAn Ethernet cable with an RJ-45 connector attached (provided)

zA management host with an Ethernet port, such as a PC or laptop

NOTE: For four-post rack or cabinet installation and other information, see the Dell

PowerConnect J-EX4500 switch documentation at

Part 1: Install a Power Supply in the Switch (If It Is Not

Installed)

1. Ensure that you have the correct power supply:

−Verify that the ejector lever and the arrows on the fan tray handles on the back of

the switch all point in the same direction.

−Verify that power supply and fan tray labels match—all say EXHAUST or INTAKE.

CAUTION: Operating the switch with an incorrect power supply might cause

the switch 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 back panel

of the switch and slide it in until it is fully seated.

4. Repeat these steps for a second power supply, if needed.

Part 2: Mount the Switch

NOTE: A switch can weigh up to 40 lb (18 kg) depending on the components that

are installed. Installation requires one person to lift the switch and a second person

to secure it to the rack.

1. Place the rack in its permanent location, allowing adequate clearance for airflow and

maintenance, and secure it to the building structure.

2. If your site has hot and cold aisle requirements, check the labels on the back of the

switch to determine whether to front-mount or back-mount the chassis:

−EXHAUST—Hot air exits the fan tray and power supplies (front-to-back airflow).

−INTAKE—Hot air exits the front of the chassis (back-to-front airflow).

NOTE: If you are mounting multiple units in the rack, mount the heaviest unit at the

bottom and mount the others from bottom to top in order of decreasing weight.

3. Determine the location on the rack where you want to mount the switch.

4. If your rack requires cage nuts, install a round-hole cage nut (clip nut) or square-hole

cage nut—and a washer—in 4 appropriately spaced holes at the same level on each

rack post.

5. Place the switch on a flat, stable surface.

6. Align the mounting brackets along the front or back of the chassis side panels

depending on whether you are front-mounting or back-mounting the switch.

7. Attach the mounting brackets to the chassis with the mounting screws, and tighten

the screws.

8. Have one person grasp both sides of the switch to lift it and position it in the rack,

aligning the mounting bracket holes with the holes in the rack posts so that the

bottom hole in each bracket lines up with a hole at the same level in each rack post.

9. Have a second person install a rack-mount screw in each hole to secure the switch to

the rack.

10. After ensuring that the chassis is level, tighten the screws.

Part 3: Connect the Switch to Earth Ground

1. Connect one end of the grounding cable to a proper earth ground, such as the rack in

which the switch is mounted.

2. Place the grounding lug attached to the grounding cable over the protective earthing

terminal on the left side of the chassis (toward the back), and secure the lug to the

terminal by tightening the screws and washers.

Part 4: Attach the Jumper Cable to the Power Supply

1. Squeeze the two sides of the jumper cable 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 jumper cable into the AC appliance inlet.

3. Push the retainer clip toward the cord until the cord slides into the slot in the

adjustment nut.

4. 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.

5. If the AC power source outlet has a power switch, set it to the OFF (0) position.

6. Repeat these steps for a second power supply, if needed.

NOTE: Do not power on the switch at this time. You will do so as part of initial

configuration. Power-on timing is particularly important for Virtual Chassis

configurations because power-on order helps determine mastership.

Part 5: Determine How You Will Operate Your J-EX4500

Switch

zStandalone—To operate your J-EX4500 as a standalone switch, go to Part 6 on

page 3 to connect power and perform initial configuration.

zJ-EX4500 Virtual Chassis—To create a Virtual Chassis with another J-EX4500 switch,

go to Part 7 on page 4.

zMixed Virtual Chassis—To create a Virtual Chassis with up to eight J-EX4200 switches

and up to one other J-EX4500 switch, go to Part 8 on page 4.
