Console port  
Front and Back Panels  
Figures 2-1 and 2-2 show the key components on the front and back panels of the NETGEAR Model  
FSM7352S Layer 3 Managed Stackable Fast Ethernet Switch  
The front panel contains LEDs, RJ-45 jacks, SFP module bays, and a console port. The back panel has a  
standard AC power receptacle for accommodating the supplied power cord.  
Figure 2-1. Front Panel of the FSM7352S Layer 3 Managed Stackable Fast Ethernet Switch  
Figure 2-2. Back Panel of the FSM7352S Layer 3 Managed Stackable Fast Ethernet Switch  
10/100/1000 Mbps RJ-45 Ports  
As Figures 2-1 and 2-3 shows, the FSM7352S Layer 3 Managed Stackable Fast Ethernet Switch has 48  
10/100 Mbps and 4 10/100/1000 Mbps RJ-45 ports. These 4 ports are auto-sensing 10/100/1000 Mbps  
ports: When you insert a cable into an RJ-45 port, the switch automatically ascertains the maximum speed  
(10, 100, or 1000 Mbps) and duplex mode (half- or full-duplex) of the attached device.  
To simplify the procedure for attaching devices, all RJ-45 ports support Auto Uplink. This technology lets  
you attach devices to the RJ-45 ports using either straight-through or crossover cables. When you insert a  
cable into the switch’s RJ-45 port, the switch automatically:  
Senses whether the cable is a straight-through or crossover cable.  
Determines whether the link to the attached device requires a “normal” connection (such as when  
connecting the port to a PC) or an “uplink” connection (such as when connecting the port to a  
router, switch, or hub).  
[SPECIAL NOTE: Ports 27 and 28 are in stacking mode by default. While you may connect and  
Page 9 of 24  
 
 
establish a link with non-stacking interfaces no traffic will pass across the interface. These interfaces  
are available to quickly and easily build a stack of switches by simply connecting two or more  
FSM7300 switches together with either Category 5 copper Ethernet cables or with SFP-based fiber  
connections.  
After ascertaining this information, the switch automatically configures the RJ-45 port to enable  
communications with the attached device, without requiring user intervention. In this way, the  
Auto Uplink technology eliminates the need for setting uplink connections or being concerned  
about whether to use crossover or straight-through cables when attaching devices.  
Figure 2-3. Warning! Creating Redundant Paths between Network Devices  
SFP module bay  
The last four ports (49,50,51,52) on FSM7352S can be used for either STP (RJ45) or SFP (fiber) type  
cable. However, both port types cannot be used at the same time. The switch will detect the port in use  
automatically simply by the first connected interface. If both connectors are plugged the SFP interface will  
operate normally and copper interface will be disabled.  
The SFP bay accommodates a standard SFP module which has an LC connector that is compatible with  
the IEEE 802.3z 1000BASE-SX standard.

on the front panel. This port is labeled Console and is required for initial management configuration of  
the switch. It also lets you manage the switch using a directly connected VT-100 terminal, personal  
computer (PC), Apple Macintosh, or UNIX workstation. The terminal, computer, or workstation connects to  
the console port using the null-modem cable supplied with your switch.  
Page 11 of 24  
 
 
The console port is configured to use the following settings:  
Baud rate: 9,600 bps  
Data bits: 8

requirements in Table 3-1.  
Table 3-1. Site Requirements  
Characteristics  
Requirements  
Mounting  
Desktop installations:  
Rack-mount  
installations:  
Provide a flat table or shelf surface.  
Use a 19-inch (48.3-centimeter) EIA standard equipment rack that is grounded  
and physically secure. You also 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.  
Provide a power source within 6 feet (1.8 meters) of the installation location.  
Power specifications for the switch is shown in Appendix C. Be sure the AC  
outlet is not controlled by a wall switch, which can accidentally turn off power  
to the outlet and the switch.  
Power source  
Environmental  
Temperature:  
Install the switch in a dry area, with ambient temperature between 0 and 40ºC  
(32 and 104ºF). Keep the switch away from heat sources such as direct  
sunlight, warm air exhausts, hot-air vents, and heaters.  
Operating humidity:  
Ventilation:  
The installation location should have a maximum relative humidity of 90%,  
non-condensing.  
Do not restrict airflow by covering or obstructing air inlets on the sides of the  
switch. Keep at least 2 inches (5.08 centimeters) free on all sides for cooling.  
Be sure there is adequate airflow in the room or wiring closet where you intend  
to install the switch.  
Operating conditions:  
Keep the switch at least 6 ft (1.83 m) away from nearest source of

Page 13 of 24  
 
 
Step 2: Installing the Switch  
You can install your NETGEAR Model FSM7352S Layer 3 Managed Stackable Fast Ethernet Switch on a  
flat surface or in a standard 19-inch rack.  
Installing 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/vibrations.  
Installing the Switch in a Rack  
To install the switch in a rack, use the following procedure (and refer to Figure 3-1). To perform this  
procedure, you need the 19-inch rack-mount kit supplied with your switch.  
1. Attach the supplied mounting brackets to the side of the switch.  
2. Insert the screws provided in the rack-mount kit through each bracket and into the bracket mounting  
holes in the switch.  
3. Tighten the screws with a #1 Phillips screwdriver to secure each bracket.  
4. Align the mounting holes in the brackets with the holes in the rack, and insert two pan-head screws with  
nylon washers through each bracket and into the rack.  
5. Tighten the screws with a #2 Phillips screwdriver to secure the switch in the rack.  
Figure 3-1. Attaching Mounting Brackets  
Step 3: Checking the Installation  
Before you apply power:  
o Inspect the equipment thoroughly.  
o Verify that all cables are installed correctly.  
o Check cable routing to make sure cables are not damaged or create a safety hazard.  
o Be sure all equipment is mounted properly and securely.  
Step 4: Applying AC Power  
NETGEAR Model FSM7352S Layer 3 Managed Stackable Fast Ethernet Switch does not have an ON/OFF  
switch; the only method of applying or removing AC power is by connecting or disconnecting 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. After you select an appropriate outlet, use the following procedure to apply  
AC power.  
Page 14 of 24  
 
 
1. Connect the female end of the supplied AC power adapter cable to the power receptacle on the back of  
the switch.  
2. Connect the 3-pronged end of the AC power adapter cable to a grounded 3-pronged AC outlet.  
When you apply power, the Power LED on the switch’s front panel will be Yellow, as it conducts a Power  
On Self Test (POST). After the switch passes the POST, the Power LED will change to Green and the  
switch is functional and ready to pass data. If the POST failed, the Power LED will blink in yellow.  
If the Power LED does not go on, check that the power cable is plugged in correctly and that the power  
source is good. If this does not resolve the problem, refer to Appendix B, Troubleshooting.  
Step 5: Connecting Devices to the Switch  
The following procedure describes how to connect devices to the switch’s network RJ-45 ports. Your  
NETGEAR Model FSM7352S Layer 3 Managed Stackable Fast Ethernet Switch contains Auto Uplink™  
technology, which allows you to attach devices using either straight-through or crossover cables.  
Figure 3-2. Connecting Devices to the Switch  
Connect each device to an RJ-45 network port on the switch’s front panel (see Figure 3-2). Use Category 5  
(Cat5) unshielded twisted-pair (UTP) cable terminated with an RJ-45 connector to make these connections.  
Note: Ethernet specifications limit the cable length between the switch and the attached device to 100 m  
(328 ft).  
Step 6: Installing a SFP Module  
The following procedure describes how to install a SFP Gigabit Ethernet module in the switch’s Gigabit  
module bays. The Standard SFP Module is sold separately from the FSM7352S. If you do not want to  
install a SFP module at this time, skip this procedure.  
To install a SFP module:  
1. Insert the SFP module into the SFP module bay. Press firmly to ensure the module seats into the  
connector.  
Page 15 of 24  
 
 
To install additional Gigabit Ethernet module, repeat this procedure  
Figure 3-3. Installing a Gigabit Ethernet fiber Module into an FSM7352S  
Step 7: Connecting to the Console Port to Manage the Switch (initial configuration)  
To learn the IP address, you must first access the Command Line management via the console interface.  
After you power-up the switch for the first time, you can connect to it using a VT100/ANSI terminal or a PC,  
Apple Macintosh, or UNIX workstation that is directly connected to the switch’s console port.  
To connect a console to the switch:  
1. Connect a VT100/ANSI terminal or a PC, Apple Macintosh, or UNIX workstation to the switch’s console  
port, labeled Console, using the null-modem cable supplied with the switch. The supplied null-modem  
cable has 9-pin connectors on each end.  
2. If you attached a PC, Apple Macintosh, or UNIX workstation, start a terminal-emulation program.  
Microsoft Windows users can use HyperTerminal, which comes with the Windows operating  
systems.  
Macintosh users can use ZTerm.  
UNIX users can use a terminal emulator such as TIP.  
3. Configure the terminal-emulation program to use the following settings:  
Baud rate: 9,600 bps  
Data bits: 8  
Parity: none  
Stop bit: 1  
Flow control: none  
4. Hit the return key, and the below screen should appear.  
Page 16 of 24  
 
 
Figure 3-4. System Information.  
5. The login name is “admin”. And there is no password assigned. We strongly recommend you enable  
password for admin access to secure access to the switch management function. After successful  
login, the screen should show (FSM7352S)> prompt. Enter “show sysinfo”, and it will display the  
management CPU’s IP address. The switch is shipped with DHCP as default to receive its IP address,  
to manually set a static IP address, you must first disable DHCP as follows:  
(FSM7352S) > en  
Password: <just hit enter>  
(FSM7352S)# network protocol none  
Changing protocol mode will reset ip configuration.  
Are you sure you want to continue? (y/n)y  
After system prompt return, enter the following command  
(FSM7352S) # network parms 192.168.1.100 255.255.255.0 192.168.1.1  
The example above uses “192.168.1.100” as IP address, and “192.168.1.1” as gateway IP address. The  
gateway address is optional.You should provide your own IP address in the above command.  
If you want to use your web browser, or telnet session to manage your switch, note the IP address on the  
Page 17 of 24  
 
 
Sysinfo page. To use your web browser, simply type the IP address in the URL address bar and hit enter.  
If you want to use an SNMP management application, you will need to note the IP address and to configure  
the SNMP settings in your switch so that it will respond to SNMP requests. This configuration can be done  
through either the console or web browser GUI. See User Guide on how to enable SNMP access.  
Note: The switch IP address is by default using DHCP mode to assign its address. If you leave the switch  
IP mode in the default DHCP mode, the IP address of your switch could change, and you would have to  
reconnect to the switch via the console port to discover the new IP address. Change the IP mode to  
Manual for a more reliable connection. If you need help changing the IP mode, please refer the User  
Manual on the Resource CD for Layer 3 Managed Switches.  
To learn more about the managed features on your switch, refer to the manual on the Resource CD.  
Step 8: Connecting the stacking modules  
Perform this step only you are setting up a stack.  
FSM7352S can be setup as part of a stack. The last two ports, port 51 and 52, are pre-configured for  
stacking functionality. To setup the stack, simply connect the switches using standard Category 5 Ethernet  
cable on ports 51 or 52. The switches will automatically select the master unit whose console will be  
accessible as normal, and other non-master unit console will no longer provide the normal CLI access. The  
following diagram illustrates how the stack can be created.  
To disable a port’s stacking mode and change it into regular gigabit Ethernet port, do the following  
commands (using port 51 as an example):  
(FSM7352S ) #config  
(FSM7352S Config ) #stack  
(FSM7352S Config-stack ) #stack-port 1/0/51 ethernet

Symptom  
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 all cables used are correct and  
comply with Ethernet specifications.  
Link LED is off or intermittent.  
Port connection is not  
working.  
Check the crimp on the connectors and make  
sure that the plug is properly inserted and  
locked into the port at both the switch and the  
connecting device.  
Make sure all cables used are correct and  
comply with Ethernet specifications. See  
Appendix D.  
Check for a defective adapter card, cable, or  
port by testing them in an alternate  
environment where all products are functioning.  
Make sure the attached device is set to auto  
negotiate.  
File transfer is slow or  
performance degradation is a  
problem.  
Half- or full-duplex setting

Additional Troubleshooting Suggestions  
If the suggestions in Table B-1 do not resolve your problem, refer to the troubleshooting suggestions in this  
section.  
Network Adapter Cards  
Make sure the network adapter cards installed in the PCs are in working condition and the software driver  
has been installed.

Configuration  
If problems occur after altering the network configuration, restore the original connections and determine  
the problem by implementing the new 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  
If required, 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. In North America, call 1-888-NETGEAR. If you are outside  
of North America, please refer to the support information card included with your product.  
Auto Negotiation  
The 10/100/1000 Mbps ports negotiate the correct duplex mode and speed if the device at the other end of  
the link supports auto negotiation. If the device does not support auto negotiation, the switch only  
determines the speed correctly and the duplex mode defaults to half-duplex.  
The gigabit port on the Gigabit module negotiates speed, duplex mode, and flow control, provided that the  
attached device supports auto-negotiation.
