Installation
This information describes installation of a S3100 series system. Dell
Networking recommends completing the installation procedures in the order
presented here.
Operation and Safety Considerations
Before installing the switch, review these operation and safety guidelines.
Review these guidelines for switch installation:
• You have enough clearance to the front of the switch so you can read the
light emitting diodes (LEDs).
• The AC power cord reaches from the power outlet to the power supply
unit (PSU) side connector.
• The switch is rack-mounted before you power it up.
• Cabling is away from sources of electrical noise, such as radios, power
lines, and fluorescent lighting. Ensure that the cabling is safely away from
other devices that might damage the cables. If needed, allow one rack unit
(RU) space between devices to provide room for cabling.
• Airflow around the switch and through the vents is unrestricted.
• Temperature around the unit does not exceed 113°F (45°C). If the switch is
in a closed or multi-rack assembly, the temperature might be higher than
normal room temperature.
• Humidity around the switch does not exceed 95 percent.
• Altitude at the installation site is below 10,000 feet.
• The switch is installed in an environment as free as possible from dust and
foreign conductive material (such as metal flakes from construction
activities). Cooling mechanisms, such as fans and blowers in the switch,
can draw dust and other particles causing contaminant buildup inside the
chassis, which can result in system malfunction.
Review these guidelines for rack mounting:
• Rack mounting — You may either place the switch on a rack shelf or
mount the switch directly into a 19" wide, EIA-310-E- compliant rack.
4Installation

• Rack loading — Overloading or uneven loading of racks may result in shelf
or rack failure, causing damage to the equipment and possible personal
injury. Stabilize racks in a permanent location before loading begins.
Mount the components starting at the bottom of the rack, then work to
the top. Do not exceed your rack load rating.
• Power considerations — Connect only to the power source specified on
the unit. When you install multiple electrical components in a rack, ensure
that the total component power ratings do not exceed the circuit
capabilities. Overloaded power sources and extension cords present fire
and shock hazards.
• Elevated ambient temperature — If you install the equipment in a closed
rack assembly, the operating temperature of the rack environment may be
greater than the room ambient temperature. The acceptable ambient
temperature ranges are listed in the S3100 Series Technical Specifications
section under Environmental Parameters.
• Reduced air flow — Install the equipment in the rack so that you do not
compromise the amount of airflow required for safe operation of the
switch. For proper ventilation, position the chassis in an equipment rack
(or cabinet) with a minimum of 5 inches (12.7 cm) of clearance around
exhaust vents.
• Reverse air flow — To ensure cool air intake and to avoid hot air blow out
from the I/O side, ensure that you have the necessary clearance.
• Reliable earthing — Maintain reliable earthing of rack-mounted
equipment. Pay particular attention to the supply connections other than
the direct connections to the branch circuit; for example, use of power
strips.
• Do not mount the equipment with the PSU side facing in a downward
position.
NOTE: Always handle the system and its components with care. Avoid
dropping the chassis or their field replaceable units.
CAUTION: Always wear an electrostatic discharge (ESD)-preventive
wrist or heel ground strap when handling a system and its
components. As with all electrical devices of this type, take all
necessary safety precautions to prevent injury when installing this
system. ESD damage can occur if components are mishandled.
CAUTION: Only trained and qualified personnel should install this
equipment. Read this guide before installing and powering up the
system.
WARNING: This is a condensed reference. Read the safety instructions
in your Safety, Environmental, and Regulatory information booklet
before you begin.

Installing a Power Supply
The S3100 systems are designed to support two hot-swappable power
supplies (PSUs) with integrated fans that provide cooling for the chassis.
1. Remove the PSU from the electrostatic bag.
2. Remove the PSU slot cover from the switch.
3. Use the grab handle to slide the PSU into the switch PSU slot. The PSU
slot is keyed such that the PSU can only be fully inserted in one
orientation.
The PSU slides into the slot smoothly. Do not force the PSU into a slot as
this action may damage the PSU or the chassis.
Figure 7. Installing a Power Supply
4. Repeat steps 1 through 3 for the second PSU.
WARNING: Electrostatic discharge (ESD) damage can occur if
components are mishandled. Always wear an ESD-preventive wrist or
heel ground strap when handling the system and its components.
Installation 13

WARNING: The PSU side includes two slots, PSU1 and PSU2. Although
the switch can run on one PSU, Dell Networking highly recommends
using two PSUs for full redundancy and additional cooling. To avoid
overheating when the switch is running with only a single PSU, Dell
Networking recommends using PSU1 (on the left when facing the PSU
side) and covering the second PSU slot opening (PSU2) with a blank
plate.
CAUTION: To prevent electrical shock, ensure that the system is
grounded properly. If you do not ground your equipment correctly,
excessive emissions may result. To ensure that the power cables meet
your local electrical requirements, use a qualified electrician.
CAUTION: Remove the power cable from the PSU prior to removing
the PSU itself. Do not connect power prior to inserting the PSU in the
switch.
NOTE: Ensure that the PSU is correctly installed. When you correctly
install the PSU, the power connector is on the right side of the PSU.
NOTE: Dell Networking recommends supplying power from the switch
PSU to the external power source only after the chassis is mounted in a
rack or cabinet.
Installing a Fan Tray
To install a fan tray, follow these steps:
NOTE: The fan tray is hot-swappable.
1. Take the fan tray out of the shipping box.
2. Use the grab handle on the fan tray to slide it into the bay.
3. Tighten the captive screws on the fan tray with a screwdriver. Ensure that
the fan tray is secure.
14 Installation

Figure 8. Installing a Fan Tray
Installing a Plug-In Module (Optional)
The S3100 series switches support optional small form-factor pluggable plus
(SFP+) or 10GBase-T modules.
When hot swapping optional modules, the following module behaviors
should be noted:
• The configuration of the port is retained when an existing module is
replaced with one that is the same.
• Replacement of an optional module with one that is different results in the
new module being moved into an error state.
• Modify the configuration of the optional module interfaces only when the
module is installed.
CAUTION: Do not insert the replacement module immediately after
removing the original module. When removing the optional module,
the syslogs must first be removed prior to installing the replacement
module.
After a module is recognized, its configuration is stored locally on the switch
as the switch default. Users can modify the configuration of these interfaces
only if the optional module is present. The module configuration appears in
the running configuration for informational purposes. For more information,
see the Dell Configuration Guide for the S3100 Series.
Installation 15

Supply Power and Power Up the System
Supply power after the switch is mounted in a rack or cabinet.
Dell Networking recommends reinspecting your system prior to powering up.
Verify that:
• The equipment is properly secured to the rack.
• The equipment rack is properly mounted and grounded.
• The ambient temperature around the unit (which may be higher than the
room temperature) is within the limits specified for the system.
• There is sufficient airflow around the unit.
• The input circuits are correctly sized for the loads and that you use
sufficient overcurrent protection devices.
• All protective covers are in place.
CAUTION: ESD damage can occur if the components are mishandled.
Always wear an ESD-preventive wrist or heel ground strap when
handling the system and its components.
Supply power to the system:
• Plug in the AC cord from the switch PSU to the external power source,
such as an AC wall outlet. Make sure that the power cord is secure.
• When the cable is connected between the system and the power source,
the switch is powered up; there is no on/off switch.
