equipment rack that is grounded and physically secure. You need the
rack-mount kit supplied with your switch.
Access Locate the switch in a position that lets you access the front panel RJ-45 ports,
view the front panel LEDs, and access the rear panel power connector.
Power source Provide a power source within 6 feet (1.8 meters) of the installation location.
Power specifications for the switch are shown in
AC outlet is not controlled by a wall switch, which can accidentally turn off power
to the outlet and the switch.
Environment Install the switch in a site free from strong electromagnetic field generators (such
as motors), vibration, dust, and direct exposure to sunlight.
Temperature The ambient switch operating temperature range is 0º to 50ºC (32º to 122ºF).
Keep the switch away from heat sources such as direct sunlight, warm air
exhausts, hot-air vents, and heaters.
Operating humidity Install the switch in a dry area with a maximum relative humidity of 90%,
noncondensing.
Ventilation Do not restrict airflow by covering or obstructing air inlets on the sides of the

Install the switch
You can install the switch on a flat surface or in a standard 19-inch rack.
Install the Switch on a Flat Surface
The switch ships with four self-adhesive rubber footpads. Stick one rubber footpad on
each of the four concave spaces on the bottom of the switch. The rubber footpads
cushion the switch against shock and vibrations.
Install the Switch in a Rack
Note: The M4100-D10-PoE is not rack mountable.
To install the switch in a rack you will need the 19-inch rack-mount kit supplied with your
switch. Keep the following considerations in mind as you install your switch:
NETGEAR Managed Switch
• Ambient operating temperature. If the switch is installed in a closed or multiunit
rack assembly, the ambient operating temperature of the rack environment might be
greater than the ambient temperature of the room. Therefore, consider installing the
equipment in an environment compatible with the maximum rated ambient
temperature.
• Reduced airflow. Mount the equipment into a rack so that the amount of airflow
required for safe operation is not compromised.
• Mechanical loading. Mount the equipment into a rack so that a hazardous condition
does not arise due to uneven mechanical loading.
• Circuit overloading. Consider the equipment’s connection to the power supply
circuitry and the effect that any possible overloading of circuits might have on
overcurrent protection and power supply wiring. Consider equipment nameplate
ratings when addressing this concern.
• Reliable grounding. This product requires reliable grounding to be maintained at all
times. To ensure this, ground the rack itself. Pay particular attention to power supply
connections other than the direct connections to the branch circuit (for example, the
use of power strips).
• Clearance. Leave enough clearance in front of the rack (about 25 inches) to enable
you to open the front door completely and in the back of the rack (about 30 inches) to
allow for sufficient airflow and ease in servicing.
To install your switch in a rack:
1. Attach the supplied mounting brackets to the side of the switch.

Check the installation
Before you apply power, perform the following checks:
1. Inspect the equipment thoroughly.
2. Verify that all cables are installed correctly.
3. Check cable routing to ensure that cables are not damaged and will not create a hazard.
4. Be sure that all equipment is mounted properly and securely.
Connect to power and check the LEDs
The switch does not have an on/off switch. The only way to apply or remove power is to
connect or disconnect the power cord. Before you connect the power cord, select an AC
outlet that is not controlled by a wall switch (which can turn off power to the switch).
To apply AC power:
1. Select an appropriate outlet.
2. Connect one end of the AC power adapter cable (M4100-DG12 or M4100-D10-PoE) or the
AC power cord to the rear of the switch, and the other end to a grounded three-pronged AC
outlet.
Note: The M4100-26G, 50G, 26-PoE, 26G-PoE, 50-PoE+, 50G-PoE, 12GF,
24G-POE+, 12G-POE+ can also obtain power from an RPS.
Supported RPS models are the RPS5412 and RPS4000.
Note: Normally the M4100-D12G and M4100-D12G-POE+ will get power
using the supplied power adapter. These switches can also get power
from a PSE (power sourcing equipment) switch if AC power is not
available. Connect port 1 of these switches to a PSE switch. The PSE
device should support IEEE802.3at so that it can provide full power to
these switches for system operation. If the PSE device used does not
support IEEE802.3at, theses switches might not operate correctly.
3. Check the Power LED on the front panel of the switch.
The LED should light in the following sequence:
• The LED turns yellow as the switch runs a power-on self-test (POST).
• If the switch passes the test, the LED turns green. The switch is working and ready to
pass data.
• If the POST fails, the Power LED blinks yellow.
Hardware Installation Hardware Installation Guide20
Page 21
NETGEAR Managed Switch
Note: If the PD LED on the front panel of the M4100-D12G and
M4100-D12G-POE+ blinks green, port 1 is connected to a
IEEE802.3af PoE device. Check the PoE device specification to make
sure that it supports IEEE802.3at.
If the Power LED does not light up, check that the power cable is plugged in correctly and
that the power source is good. For more information, see
Troubleshooting on page 24.
SFP modules
SFP modules (sold separately) can be inserted directly into the switch’s ports.
Note: Use only optical transceiver modules that are UL approved and that
are certified as Laser class 1 products.
• AGM731F: SFP module with LC connector
1000Base-SX standard
• AGM732F: SFP module with LC connector
1000Base-LX standard
• AFM735: SFP module with LC connector
standard
To insert an SFP module into the switch port:
1. Insert the module into the switch port.
2. Press firmly to ensure that the module seats into the connector

Connect equipment to the switch
You can connect devices, a Gigabit Ethernet module, and/or a console to the switch.
RJ-45 Ports
The switch uses Auto Uplink technology, which enables you to attach devices using either
straight-through or crossover cables. Use a Category 5 (Cat 5) unshielded twisted-pair (UTP)
cable terminated with an RJ-45 connector.
Note: Ethernet specifications limit the cable length between the switch and
the attached device to 328 feet (100 meters).
Connect a console to the switch
After you install the switch and apply power, you can connect to it with a terminal or
workstation. You can use the command-line interface (CLI) to identify the IP address.
To use a console, you need the following items:
• VT100/ANSI terminal, or a Windows computer
workstation
• USB console cable (shipped with the product) or a null-modem cable (shipped with the
product) with 9-pin connectors on each end
To connect a console to the switch:
1. Connect the null-modem cable to the console port on the rear of the switch, or connect
the USB console cable to the USB console port on the rear of the switch.
, Apple Macintosh computer, or UNIX
Console ports
2. Select the console port through the console slide switch on the rear panel:
a. Select the mini USB (cable included) as the console port by pushing the slide switch
to the left.

Troubleshooting chart
The following table lists symptoms, causes, and solutions to possible problems.
Table 3. Troubleshooting chart
Problem Cause Solution
Power LED is off. No power is received. Check the power cord connections for the switch
at the switch and the connected device.
Make sure that all cables used are correct and
comply with Ethernet specifications.
Link LED is off or intermittent. Port connection is not
working.
Slow file transfer or there is
performance degradation.
A segment or device is not
recognized as part of the
network.
ACT LED blinks continuously
on all connected ports and the
network is disabled.
Half- or full-duplex setting on
the switch and the connected
device are not the same.
One or more devices are not
properly connected, or cabling
does not meet Ethernet
guidelines.
A network loop (redundant
path) has been created.
• Check the crimp on the connectors. Make
sure that the plug is fully inserted and locked
into the port at both the switch and the
connecting device.
• Make sure that all cables used are correct
and comply with Ethernet specifications.
See
Appendix A.
• Check for a defective adapter card, cable, or
port by testing it in an alternate environment
where all products are functioning.
• Make sure that the attached device is set to
autonegotiate.
• Check the system message log.
Verify that the cabling is correct. Be sure that all
connectors are securely positioned in the

Additional troubleshooting suggestions
If the suggestions in Table 3 do not resolve your problem, refer to the troubleshooting
suggestions in this section.
• Network adapter cards:
Make sure that the network adapter cards installed in the computers are in working
condition and the software driver has been installed.
• Configuration:
If problems occur after you change the network configuration, restore the original
connections. Then find the problem by making the changes, one step at a time. Make
sure that cable distances, repeater limits, and other physical aspects of the installation do
not exceed the Ethernet limitations.
• Switch integrity:
You can verify the integrity of the switch by resetting the switch. To reset the switch, use
the Tools > Reset command, or remove AC power from the switch and then reapply AC
power. If the problem continues, contact NETGEAR technical support.
• Autonegotiation:
The copper 10/100/1000 Mbps ports negotiate the correct duplex mode and speed if the
device at the other end of the link supports autonegotiation. If the device does not support
autonegotiation, the switch determines only the speed correctly and the duplex mode
defaults to half-duplex. The fiber gigabit ports negotiate speed, duplex mode, and flow
control if the attached device supports autonegotiation.
