Overview

Your NETGEAR Model GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable Switch provides
the benefit of management with a complete package of features for the observation, configuration, and
control of your network. With a web-based Graphical User Interface (GUI), the switch’s many capabilities
can be viewed and used in a simple and intuitive manner. For those who prefer a more traditional
interface, there is Command Line Interface (CLI) available through the console port on the front or a telnet
connection via the network. The switch’s management features include SNMP and RMON for port and
switch information, VLAN for traffic control, port trunking for increased bandwidth, and Class of Service
(CoS) for traffic prioritization. These features and more will allow you to better understand and better
control your network.

Your NETGEAR Model GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable Switch also
provides four fiber Gigabit Ethernet ports using miniGBIC fiber connector located on the front panel. The
Small Form-Factor Pluggable (SFP) module ports will accept any standard SFP module. Using these
Gigabit ports, you can create high-speed connections to a server or network backbone. For example, you
can connect:

• Switches to each other with high-speed links

• High-speed servers

CHAPTER 2: PHYSICAL DESCRIPTION

This chapter describes the hardware features of the NETGEAR Model GSM7328S ProSafe 24+4 Gigabit
Ethernet L3 Managed Stackable Switch. Topics include:

Front and back panels
10/100/1000 Mbps auto-sensing RJ-45 ports
SFP module ports
10 Gigabit Ethernet / 24 Gigabit Stacking I/O module bays
LED descriptions
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
GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable 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 GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable Switch

Figure 2-2. Back Panel of the GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable Switch

10/100/1000 Mbps RJ-45 Ports

As Figures 2-1 and 2-3 shows, the GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable
Switch has 24 10/100/1000 Mbps RJ-45 ports. These 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

Page 10 of 24

router, switch, or hub).

• 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 ports

The last four ports (21(21F),22(22F),23(23F),24(24F)) on GSM7328S can be used for either copper UTP
(RJ45) or SFP (fiber) type cabling. 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 module ports accommodate NETGEAR AGM731F (1000BASE-SX), AGM732F (1000BASE-LX),
AGM733 (1000BASE-ZX) modules. or any standard SFP module which has an LC connector that is IEEE

802.3z compliant.

10 Gigabit Ethernet / 24 Gigabit Stacking I/O module bays

The high speed I/O module bays can be utilized for either standards-based 10-Gigabit Ethernet or special
24-Gigabit Stacking connectivity. With the AX742 24-Gigabit Stacking module and special cabling you can
connect up to 8 switches to form a stack with a single management IP address. Two of the I/O module
slots can be used for stacking purposes while the remaining two I/O module bays can be used for
10-Gigabit Ethernet uplinks. If the stacking functionality is not needed, all four I/O modules can be used for
10-Gigabit Ethernet applications by using the AX741 adapter and XFP modules.

non-condensing.

Page 14 of 24

Ventilation: 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

electromagnetic noise, such as a photocopy machine.

Step 2: Installing the Switch

You can install your NETGEAR Model GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable
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.

Page 15 of 24

Step 4: Applying AC Power

NETGEAR Model GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable 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.

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 GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable Switch contains Auto
Uplink™ technology, which allows you to attach devices using either straight-through or crossover cables.

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 GSM7328S. If you do not want to
install a SFP module at this time, skip this procedure.

To install a SFP module:

Page 16 of 24

1. Insert the SFP module into the SFP module bay. Press firmly to ensure the module seats into the
connector.

To install additional Gigabit Ethernet module, repeat this procedure

Figure 3-3. Installing a Gigabit Ethernet fiber Module into an GSM7328S

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 17 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 (GSM7328S)> 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:

(GSM7328S) > enable
Password: <just hit enter>

After system prompt return, enter the following command

(GSM7328S) #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

(GSM7328S) # network parms 192.168.1.100 255.255.255.0 192.168.1.1

NOTE: This assigns an IP address to the switch in the management VLAN (default: vlan 1). The

Page 18 of 24

management VLAN is a special VLAN that is isolated from other normal routable VLANs for security
reasons. If you wish to assign an IP address to the switch in a normal VLAN, please follow the instructions
found in Chapter 6: Quick Startup of the User Manual for the Netgear 7300 Series Layer 3 Managed Switch
Software.

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
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 if you are setting up a stack of switches.
GSM7328S can be setup as part of a stack. To setup the stack, first plug the AX742 24 Gigabit Stacking

modules into the available I/O module bays at the front or the rear of the case, then connect the provided
stacking XENPAK cables to the same AX742 24 Gigabit Stacking modules on the other 2 GSM7328S or
GSM7352S (upstream and downstream). The switches will automatically select a master unit. Once the
master is selected its console will be accessible as normal, and other non-master units’ console ports will
no longer provide the normal CLI access. The following diagram illustrates how the stack can be created.

Step 9: Setup 10 Gigabit Ethernet Connections

To set up a 10 Gigabit Ethernet connection, first plug an AX741 10 Gigabit Ethernet XFP Adapter into one
of the available I/O module bays.

Figure 3-5. Connecting the stacking modules

Page 19 of 24

Then insert either an AXM751 10GBASE-SR or AXM752 10GBASE-LR XFP module or other standard
XFP fiber module into the open XFP socket on the AX741 (see figure).

If the user wants to support more than two 10 Gigabit Ethernet connections, then any of the additional I/O
module bays can be used with an AX741 to accommodate more 10 Gigabit Ethernet ports.

Step 10: Connecting to RPS System

Your NETGEAR Model GSM7328S ProSafe 24+4 Gigabit Ethernet L3 Managed Stackable Switch has a
redundant power supply connector in the back. You may choose to connect a DC to DC power supply to
the switch to ensure that it won’t fail in case the primary power supply does. To connect an RPS to the
switch, first make sure the switch is turned off, and then connect the RPS to the switch as illustrated below.
Once all connections are completed, turn the switch back on.

Additional Troubleshooting Suggestions

switch at the switch and the connected device.
Make sure all cables used are correct and
comply with Ethernet specific ati ons .
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 specific ati ons . 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.

Check System message log.
Verify that the cabling is correct. Be sure all
connectors are securely positioned in the

required ports. Equipment may have been
accidentally disconnecte d.
Break the loop by ensuring that there is only
one path from any networked device to any
other networked device.

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.

Page 24 of 24

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 Integr ity

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.
