Installing the PowerConnect 3324/3348 Switch

Dell™ PowerConnect™ 3324/3348 User's Guide

Installation Precautions

CAUTION: The rack or cabinet housing the switch should be adequately secured to prevent it from becoming unstable and/or falling over.

CAUTION: Ensure the power source circuits are properly grounded.

CAUTION: Observe and follow service markings. Do not service any product except as explained in your system documentation. Opening or removing covers marked with a triangular symbol with a lighting bolt may cause electrical shock. These components are to be serviced by trained service technicians only.

CAUTION: Ensure the power cable, extension cable, and/or plug is not damaged.

CAUTION: Ensure the product is not exposed to water.

CAUTION: Do not push foreign objects into the device, as it may cause a fire or electric shock.

CAUTION: Allow the product to cool before removing covers or touching internal equipment.

CAUTION: Ensure the switch does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add together the ampere ratings of all switches installed on the same circuit as the switch. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the switch, near their AC power connectors.

NOTICE: Ensure the device is not exposed to radiators and/or heat sources.

NOTICE: Ensure the cooling vents are not blocked.

NOTICE: Use the device only with approved equipment.

NOTICE: Do not install the switch in an environment where the operating ambient temperature might exceed 40ºC (122ºF).

NOTICE: Ensure the air flow around the front, sides, and back of the switch is not restricted.

Site Requirements

Dell™ PowerConnect™ 3324/3348 series equipment can be mounted in a standard 19-inch equipment rack or placed on a table. Before installing the unit, verify that the location chosen for installation meets the site requirements described below.

General—Ensure that the power supply is correctly installed.
Power—The unit is installed within 1.5 m (5 feet) of a grounded, easily accessible outlet 100-250 VAC, 50-60 Hz. It is preferred that two separate power supplies are provided, for example, a UPS and a separated phased supply.
Clearance—There is adequate frontal clearance for operator access. Allow clearance for cabling, power connections, and ventilation.
Cabling—Cabling is routed to avoid sources of electrical noise such as radio transmitters, broadcast amplifiers, power lines, and fluorescent lighting fixtures.
Ambient Requirements—The ambient unit operating temperature range is 0 to 40ºC (32 to 122ºF) at a relative humidity of up to 95%, non-condensing. Verify that water or moisture cannot enter the case of the unit.

Device Rack Installation

CAUTION: Disconnect all cables from the unit before mounting the PowerConnect 3324/3348 switch in a rack or cabinet.

Installing PowerConnect 3324/3348:

Ground yourself by putting on an ESD wrist strap and attaching the ESD clip to a metal surface.
Place the PowerConnect 3324/3348 switch on a flat and stable surface.
Place the supplied rack-mounting bracket on one side of the PowerConnect 3324/3348. Ensure that the mounting holes on the PowerConnect 3324/3348 line up with the mounting holes on the rack-mounting bracket.
Insert the supplied screws into the rack-mounting holes and tighten with a Phillips screwdriver.
Repeat the process for the rack-mounting bracket on the other side of PowerConnect 3324/3348.
Insert the unit into the 19-inch rack and secure the unit to the rack with the rack screws (not provided by the PowerConnect 3324/3348 supplier). When securing, fasten the lower pair of screws before the upper pair of screws to ensure that the weight of the unit is evenly distributed during installation. Ensure that the ventilation holes are not obstructed.

Installing the Switch without a Rack

The PowerConnect 3324/3348 must be installed on a flat surface if it is not installed on a rack. The surface must be able to support the weight of the device and the device cables.

Set PowerConnect 3324/3348 on a flat surface, leaving 2 inches on each side and 5 inches at the back.
Ensure that the device has proper ventilation.
Attach the rubber feet to the bottom of the device to prevent the device from slipping.

Stacking PowerConnect 3324/3348

PowerConnect 3324/3348 supports stacking up to six PowerConnect 3324/3348 devices or up to 192 Fast Ethernet ports and six Giga ports. Each PowerConnect 3324/3348 stack contains a single Master unit, while the remaining units are considered stacking members. All management is done through the Master unit. Both 24-port and 48-port devices can be included in the stack.

To enable stacking, units must be stacked with a Stack Module connected to port G2 in the SFP slot.

Connecting Stacking Cables

Place each device in the rack or on a flat surface.
Insert a stacking connector for each G2 port.

USB Connector

Connect the Master unit lower RX stacking connector to the selected member upper TX port.
Connect the stack in a stacking ring topology, where stacking cables are connected from the lower RX stacking connector into the upper TX Stacking connector.
Ensure that the upper and lower stack members are connected via a stacking cable. The following figure depicts a correctly connected stack:

NOTE: If the Stacking ring is not completed, the stack does not function.

Connected Stack

For more information on configuring stacks, see "Configuring Stacking".

Connecting the PowerConnect 3324/3348 to a Power Supply

The following section contains instruction for connecting the PowerConnect 3324/3348 to a AC power connection. The PowerConnect 3324/3348 is supplied with power from:

AC power supply source.
An optional PowerConnect RPS-600 redundant power supply.
Both AC and DC sources.

Connecting PowerConnect 3324/3348 to a Power Supply

Plug in the PowerConnect 3324/3348 to one of the previously listed power sources.

AC Power Connection

AC power should be supplied to the unit through a 1.5m (5 foot) standard power cable with safety-ground connected.

To connect power to PowerConnect 3324/3348:

Connect the power cable to the AC main socket located on the rear panel. If there is a redundant power module, connect this redundant power module cable to a separate power supply.
Connect the power cable to a grounded AC outlet.
Confirm that the device is connected and operating correctly by examining the LEDs on the front panel. For more information about LEDs, see "LED Definitions".

Cable, Port, and Pinout Information

This section describes the PowerConnect 3324/3348 physical interfaces and provides information about cable connections. Stations are connected to PowerConnect 3324/3348 ports through the physical interface ports on the front panel. For each station, the appropriate mode (Half/Full Duplex, Auto) is set.

Port Connections

The ports are all standard RJ45 Ethernet ports. Switching ports can connect to stations wired in standard RJ45 Ethernet station mode using straight cables. Transmission devices use crossed cables to connect to each other.

The following figure illustrates the RJ45 pin number allocations for the 10/100M ports.
