Installation
Overview
This document provides basic information to install and start running the following
PowerConnect 2800 series of Web-managed Gigabit Ethernet switches:
• PowerConnect 2808
• PowerConnect 2816
• PowerConnect 2824
• PowerConnect 2848
The PowerConnect 2800 series can be used to connect workstations and other network devices,
such as:
•Servers
•Hubs
•Routers
The PowerConnect devices are primarily intended for the Small Office/Home Office (SOHO)
that require high performance edge connectivity. These PowerConnect devices are ideal for the
small to medium business that requires high performance network connectivity along with
advanced web management features. The PowerConnect management features are designed to
minimize administrative management effort, while enhancing and improving network traffic
control.
The switch is delivered from the factory in Unmanaged Mode. If users wish to use the switch as an
unmanaged switch, they can simply plug the switch in and start using it. No configuration is
necessary. If the same user wishes to use the switch as a managed switch, they need to change the
mode from Unmanaged to Managed, as described in the Dell™ PowerConnect™ 2800 Series
User’s Guide, available on the Documentation CD. Alternatively, you may check the Dell support
website at www.support.dell.com for the latest documentations and software updates.
Site Preparation
Site Requirements
The PowerConnect 2808/16/24/48 devices can be mounted in a standard equipment rack, placed
on a tabletop, or mounted on the wall.

6Installation
Before installing the device, verify that the site selected for the device meets the following site
requirements:
• Power — The device is installed within 1.5 m (5 feet) of a grounded, easily accessible outlet 220/110
VAC, 50/60 Hz.
• General — Ensure that the power supply is correctly installed.
• 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 device operating temperature range is 0 to 45 °C (32 to
113 °F) at a relative humidity of up to 95%, non-condensing. Verify that water or moisture cannot
enter the device case.

Mounting the Device
Overview
The following mounting instructions apply to the PowerConnect 2808/16/24/48 devices. There are
three device mounting options:
• Installing in a Rack
• Installing on a Flat Surface
•InstallingonaWall
Installation Precautions
CAUTION Before performing any of the following procedures, read and follow the safety instructions
located in your Product Information Guide.
CAUTION Observe the following points before performing the procedures in this section:
• Ensure that the rack or cabinet housing the device is adequately secured to prevent it from
becoming unstable and/or falling over.
• Ensure that the power source circuits are properly grounded.
• Observe and follow the service markings. Do not service any device except as explained in the
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.
• Ensure that the power cable, extension cable, and/or plug is not damaged.
• Ensure that the device is not exposed to water.
• Ensure that the device is not exposed to radiators and/or heat sources.
• Ensure that the cooling vents are not blocked.
• Do not push foreign objects into the device, as it may cause a fire or electric shock.
• Use the device only with approved equipment.
• Allow the device to cool before removing covers or touching internal equipment.

8Mounting the Device
• Ensure that the device 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
devices installed on the same circuit as the device. Compare this total with the rating limit for the
circuit.
• Do not install the device in an environment where the operating ambient temperature might exceed
40ºC (104ºF).
• Ensure that the airflow around the front, sides, and back of the device is not restricted.
Device Rack Installation
CAUTION: Read the safety information in the Product Information Guide as well as the safety information for
other devices that connect to or support the device.
CAUTION: Disconnect all cables from the device before mounting the device in a rack or cabinet.
CAUTION: When mounting multiple devices into a rack, mount the devices from the bottom up.
Install the device in a rack as follows:
1
Place the supplied rack-mounting bracket on one side of the device ensuring the mounting holes on
the device line up to the mounting holes on the rack mounting bracket. The following figure
illustrates where to mount the brackets.
Figure 2-1. Bracket Installation for Rack Mounting
2 Insert the supplied screws into the rack mounting holes and tighten with a screwdriver.
3 Repeat the process for the rack-mounting bracket on the other side of the device.

Mounting the Device 9
4 Insert the device into the rack, ensuring the rack-mounting holes on the device line up to the
mounting hole on the rack.
5 Secure the device to the rack with the rack screws (not provided). Fasten the lower pair of screws
before the upper pair of screws. Ensure that the ventilation holes are not obstructed.
Installing on a Flat Surface
The device can 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.
1
Attach the self-adhesive rubber pads (provided with the device) on each marked location on the
bottom of the chassis.
2 Set the device on a flat surface, while leaving 2 inches (5.08 cm) on each side and 5 inches (12.7 cm)
at the back.
3 Ensure that the device has proper ventilation.
Installing on a Wall
To mount the device on a wall:
1 Ensure that the mounting location meets the following requirements:
• The surface of the wall must be capable of supporting the device.
• Allow at least 2 inches (5.1 cm) space on the sides for proper ventilation and 5 inches (12.7 cm)
at the back for power cable clearance.
• The location must not be exposed to direct sunlight.
• The location must be at least 2 feet (61 cm) away from any heating vents, and no area-heating
vent should point towards the device.
• The location must be ventilated to prevent heat buildup.
• Do not locate the device near any data or electrical cabling.
• The power cable must be able to reach an outlet.
2 Place the supplied wall-mounting bracket on one side of the device, ensuring that the mounting
holes on the device line up to the mounting holes on the wall-mounting bracket. The following
figure illustrates where to mount the brackets.

10 Mounting the Device
Figure 2-2. Bracket Installation for Wall Mounting
3 Insert the supplied screws into the wall-mounting bracket holes and tighten with a screwdriver.
4 Repeat the process for the wall-mounting bracket on the other side of the device.
5 Place the device on the wall in the location where the device is being installed.
6 On the wall mark the locations where the screws to hold the device must be prepared.
7 On the marked locations, drill the holes and place all plugs (not provided) in the holes.
8 Secure the device to the wall with screws (not provided). Ensure that the ventilation holes are not
obstructed.
