Dell PowerConnect J-Series J-EX4200 Ethernet Switch Quick Start
To install and configure a Dell PowerConnect J-Series J-EX4200 Ethernet Switch
(regulatory model numbers EX4200-24T, EX4200-24F, and EX4200-48T), you need:
Two mounting brackets and eight mounting screws (provided)
Phillips (+) screwdriver number 2 to remove and tighten screws
Hardware to secure the chassis to the rack (provided)
Jumper cord and cord retainer (provided)
Grounding cable—minimum 14 AWG (2 mm²), minimum 90°C wire—with Panduit
LCD6-14BH-L grounding lug or equivalent attached by a licensed electrician
Two 10-32x.25-in. screws with split washers to secure the grounding lug to the switch
Management host, such as a PC, with an Ethernet port
Ethernet cable (provided)
NOTE: A Virtual Chassis cable and two cable connector retainers are provided, but their
use is not covered here. These instructions are for two-post rack installation only. For
four-post rack or wall installation, Virtual Chassis configuration, and other tasks, see the
PowerConnect J-EX4200 switch documentation at
NOTE: Four-post rack-mount and wall-mount kits are available separately.
Part 1: Install a Power Supply in the Switch (If It Is Not Installed)
1. Remove the power supply from the bag. Take care not to touch power supply
components, pins, leads, or solder connections.
2. Push down on the locking lever on the left front of the power supply until it is in its
lowest position (see the figure in Part 4 for the location of the locking lever). You
might need to loosen the locking lever screw to move the lever.
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.
4. Push the locking lever up to its highest position (this action might pull the power
supply in). Tighten the locking lever screw using the screwdriver.
Part 2: Mount the Switch

.
1. Place the switch on a flat, stable surface.
2. Attach the mounting brackets to the switch chassis with the eight mounting screws.
3. Make sure the rack is properly secured to the building in its permanent location.
4. Have one person grasp both sides of the switch, lift it, and position it in the rack,
aligning the bracket holes with the holes in the rack.
5. Have a second person install a rack-mount screw—and cage nut and washer if your
rack requires them—in each of the four bracket holes to secure the switch to the rack.
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, and secure the lug to the terminal with the
screws and washers.
Part 4: Connect AC Power to the Switch
NOTE: If you are interconnecting multiple switches as a Virtual Chassis, power on only
one switch—the one you will use as the master.
1. Squeeze the two sides of the 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 on the
power supply faceplate.
2. Insert the coupler end of the jumper cord into the AC appliance inlet.
3. Push the cord into the slot in the adjustment nut of the cord retainer. 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 jumper cord plug into the power source outlet.
6. Repeat these steps for each AC power supply.
7. If the AC power source outlet has a power switch, set it to the ON (|) position.
NOTE: When you connect power to the switch, the Alarm (ALM) LED lights red (major
alarm) to indicate that the network is disconnected. This behavior is normal. Plugging an
active Ethernet cable into the management (MGMT) port on the switch completes the
network link and turns the ALM LED to amber (minor alarm).
The ALM LED turns off when you create a backup rescue configuration.
