Package Contents

Overview

Your NETGEAR Model GSM712 Managed Gigabit 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 a Command Menu Interface available through the console port on the front or via Telenet. 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 GSM712 Managed Gigabit Switch also provides two GBIC module bays. The GBIC module bays will accept any standard GBIC module, including the AGM721F 1000BASE-SX module or AGM721T 1000BASE-T module from NETGEAR. 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 long distance, high-speed links

• Combine fiber and copper networks

Your NETGEAR Model GSM712 Managed Gigabit Switch can operate free-standing, or rack mounted in a wiring closet or equipment room. It is IEEE-compliant and offers low latency for high-speed networking. It includes 10 auto-sensing 10/100/1000 Ethernet/Fast Ethernet/Gigabit Ethernet ports. The 10/100/1000 Mbps ports are shielded RJ-45 ports that automatically negotiate to the highest speed. This capability makes the switch ideal for environments that have a mix of Ethernet, Fast Ethernet, and Gigabit Ethernet devices. In addition, all 10/100/1000 Mbps ports operate in half- or full-duplex mode. The maximum segment length is 328 feet (100 meters) over Category 5 unshielded twisted-pair (UTP) cable.

Front Panels

Figures 2-1 and 2-2 show the key components on the front and back panels of the NETGEAR Model GSM712 Managed Gigabit Switch.

The front panel contains LEDs, Rest Button, RJ-45 jacks, GBIC 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 GSM712 Managed Gigabit Switch

Figure 2-2. Back Panel of the GSM712 Managed Gigabit Switch

10/100/1000 Mbps RJ-45 Ports

As Figure 2-1 shows, the GSM712 Managed Gigabit Switch has 10 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 or 100 or 1000 Mbps) and duplex mode (half- or full-duplex) of the attached device. The 10/100/1000 Mbps ports support only unshielded twisted-pair (UTP) cable terminated with an 8-pin RJ-45 plug.

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, and

• 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).

• 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 compensates for setting uplink connections, while eliminating concern about whether to use crossover or straight-through cables when attaching devices.

Warning!

active paths between any two network devices can cause undesirable loops in the network, resulting in an endless broadcast traffic that disables your network. Loops occur when there are alternate routes between two network devices. In Figure 2-3, for example, a loop is created by connecting two RJ-45 ports on a NETGEAR Model GSM712 Managed Gigabit Switch to a router containing a 4-port switch. The Spanning Tree protocol will prevent loops, if that advanced feature is enabled.

You must use Link Aggregation (a.k.a. Port Trunking) to create multiple links between switches. Using Auto Uplink to create multiple

GBIC Module Bays

our NETGEAR Model GSM712 Managed Gigabit Switch has two Gigabit GBIC module ports. The Gigabit Ethernet ports provide a full-duplex

1000 Mbps (1 Gbps) connection that effectively doubles throughput to 2 Gbps.

The GBIC bay accommodates a standard GBIC module, such as the NETGEAR AGM721F GBIC module or the AGM721T GBIC module. The AGM721F GBIC module has an SC connector that is compatible with the IEEE 802.3z 1000BASE-SX standard, while the AGM721T has an RJ-45 connector and is compliant with the IEEE 802.3ab 1000BASE-T standard.

LED Descriptions

The front panel of the NETGEAR Model GSM712 Managed Gigabit Switch has LEDs that provide a quick and accurate display of port speed, activity, collisions, and duplex mode. Table 2-1 summarizes the LEDs on the switch and Gigabit Ethernet module.

Step 3: Installing a GBIC Module

The following procedure describes how to install a GBIC Gigabit Ethernet module, such as the NETGEAR AGM721F, in the switch’s Gigabit module bays. The AGM721F is sold separately from the GSM712. If you do not want to install a GBIC module at this time, skip this procedure.

To install a GBIC module:

7. Insert the GBIC module into the GBIC module bay. Press firmly to ensure the module seats into the connector.

Figure 4-2. Installing a Gigabit Ethernet Module

Step 4: 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 5: Applying AC Power

NETGEAR Model GSM712 Managed Gigabit Switches do 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.

8. Connect the female end of the supplied AC power adapter cable to the power receptacle on the back of the switch.

9. Connect the 3-pronged end of the AC power adapter cable to a grounded 3-pronged AC outlet.

When you apply power, the passes the POST, the

Step 6: Connecting to the Console Port to Manage the Switch (initial configuration)

Your NETGEAR Model GSM712 Managed Gigabit Switch contains software for viewing, changing, and monitoring the way it works. This management software is not required for the switch to work. However, the management software can let you improve the efficiency of the switch and, as a result, improve its overall performance as well as the performance of your network. The remainder of this section describes how to initialize the management software to the first time you use the management features.

After you power-up the switch for the first time, you can configure it using a VT100/ANSI terminal or a PC, Apple Macintosh, or UNIX workstation that is directly connected to the switch’s console port. Thereafter, you can assign an IP address, subnet mask, and gateway address to the switch and manage it through a Web browser, Telnet session, or SNMP management application. For more information about using the console, see Chapter 6, Administration Console Access.

To connect a console to the switch:

10. Connect a VT100/ANSI terminal or a PC, Apple Macintosh, or UNIX workstation to the switch’s console port, labeled Console, using the nullmodem cable supplied with the switch. The supplied null-modem cable has 9-pin connectors on each end.

11. 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.

12. 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

Figure 4-3 System Information

Page 17 of 105

13. The terminal-emulation program should display the System Description page. Hit the ‘ESC’ key to get to the Main Menu page.

14. On the Main Menu page, hit the ‘C’ key to select the Set-Up page.

Figure 4-5 Set-Up

Page 19 of 105

15. On the Set Up page, hit the ‘B’ key to select the IP Configuration page.

Figure 4-6 IP Configuration

16. On the IP Configuration page, type in the desired IP Address for this switch, followed by the ‘Enter’ key.

: this switch is not DHCP client capable. You must assign a static IP address to the switch.

Note

17. Now type in the desired Network Mask, followed by the ‘Enter’ key.

18. Now type in the desired Default Gateway, followed by the ‘Enter’ key.

19. Use Ctrl-W to save these new settings. Hit the ‘Y’ key or ‘Enter’ to confirm saving the new settings to NVRAM.

The switch will now reset, loading the new IP address. At this point you can use your web browser to manage your switch through the network. After you have connected your computer to the switch via one of the network ports, simply launch your web browser and type the IP address in the Address Bar to use the Graphical User Interface (GUI) for configuration, observation, and management of your switch.

Step 7: Connecting Devices to the Switch

The following procedure describes how to connect devices to the switch’s RJ-45 ports. Your NETGEAR Model GSM712 Managed Gigabit Switch contains Auto Uplink™ technology, which allows you to attach devices using either straight-through or crossover cables.

Figure 4-7. Connecting Devices to the Switch

20. Connect each device to an RJ-45 network port on the switch’s front panel (see Figure 4-9). Use Category 5 (Cat5) unshielded twisted-pair (UTP) cable terminated with an RJ-45 connector to make these connections.

: Ethernet specifications limit the cable length between the switch and the attached device to 100 m (328 ft).

SNMP Access

With this access method, you can use an external Simple Network Management Protocol (SNMP) -based application to manage your NETGEAR Model GSM712 Managed Gigabit Switch. Figure 5-1 shows an example of this management method.

This management method requires the SNMP agent on the switch and the SNMP Network Management Station to use the same community string. This management method, in fact, uses two community strings: the GET community string and the SET community string. If the SNMP Network management Station only knows the SET community string, it can read from and write to the MIBs. However, if it only knows the GET community string, it can only read MIBs. The default GET community string for the switch is ‘public’.

Figure 5-1. SNMP-Based Management Method

Protocols

Your NETGEAR Model GSM712 Managed Gigabit Switch supports the following protocols:

Virtual terminal protocols, such as Telnet

SNMP

Virtual Terminal Protocols

A virtual terminal protocol is a software program, such as Telnet, that allows you to establish a management session from a Macintosh, a PC, or a UNIX workstation. Because Telnet runs over TCP/IP, you must have at least one IP address configured on the NETGEAR Model GSM712 Managed Gigabit Switch before you can establish access to it with a virtual terminal protocol.

Terminal emulation differs from a virtual terminal protocol in that you must connect a terminal or PC directly to the console port. Figure 5-2 shows a UNIX workstation connected to the system through a virtual terminal protocol (Telnet), and a terminal connecting directly to the console port through a null-modem cable.

Figure 5-2. Administration Console Access

SNMP Protocol

SNMP is the standard management protocol for multi-vendor IP networks. SNMP supports transaction-based queries that allow the protocol to format messages and to transmit information between reporting devices and data-collection programs. SNMP runs on top of the User Datagram Protocol (UDP), offering a connectionless-mode service.

Software Upgrade Procedure

The application software is field upgradeable. The upgrade procedure and the required equipment is described in the following section.

Note that once the system is up, it is controlled by an executing application image residing in non-volatile memory. No software upgrade is possible during this mode. The upgrade can only be done when the system is resetting. To initiate this sequence, the user must set the ‘Next Boot From’ configuration parameter to ‘Boot from Net’ during normal operation, and then perform a ‘reset’. When the ‘Boot from Net’ option is set, the switch

Page 23 of 105

will start using an image residing on a TFTP server on the network. Be sure that the TFTP server residing on the network is accessible by the switch. Once completed, the software version should be verified in the System page.

: It is highly recommended, though not necessary, to use a RS-232 serial port connection to the switch during the software upgrading

Note

procedure. When using a Telnet Session or web interface alone, your connection to the switch will not be available until the switch has entered forwarding mode. This takes approximately three minutes.

The upgrade procedure is as follow:

Go to Main Menu>Tools>Software Upgrade (in the Web or Console Interface).

2. Select ‘Boot from Net’ option.

3. Verify information such as the IP address for the TFTP Server, Gateway IP address, and the file name and its path of the new image.

4. Save the setting in non-volatile memory. In the Browser interface, use the ‘Apply’ button, and the Tools> Save Configuration screen. In the console interface, use Ctrl-W and confirm the change to NVRAM.

5. Restart the system via the Tools>Reset command

6. Bootstrap will retrieve the new image then pass control to it. The system executes the new software image.

: the previous image in non-volatile memory will not be replaced by the new image using this option. The image in non-volatile memory will

only be over-written if ‘Boot from Net and Save’ option is selected.

8. Test your switch to make sure the new image is working correctly. If you decide to keep the new image, go to Software Download again. Select ‘Boot from Net & Save’ option.

9. Save the setting in non-volatile memory. In the Browser interface, use the ‘Apply’ button, and the Tools> Save Configuration screen. In the console interface, use Ctrl-W and confirm the change to NVRAM.

10. Restart the system via the Tools>Reset command The new image should over-write the old image in non-volatile memory. Verify it by going to the Software Download screen and checking the

CHAPTER 6: ADMINISTRATION CONSOLE ACCESS

The administration console is an internal, character-oriented, VT-100/ANSI menu-driven user interface for performing management activities. Using this method, you can view the administration console from a terminal, PC, Apple Macintosh, or UNIX workstation connected to the switch’s console port. Figure 6-1 shows an example of this management method.

Figure 6-1. Administration Console Management Method

Direct Access

Direct access to the switch console is achieved by connecting the switch’s console port to a VT-100 or compatible terminal or to a PC, Apple Macintosh, or UNIX workstation equipped with a terminal-emulation program. This connection is made using the null-modem cable supplied with the switch.

The following list provides examples of terminal-emulation programs:

The terminal-emulation program should use the following settings:

The direct access management method is required when you configure the switch for the first time. Thereafter, we recommend you use the Web management access method (described in chapter 7) to manage the switch.

HyperTerminal (which is built into the Microsoft Windows operating systems)

ZTerm (Apple Macintosh)

TIP (UNIX workstation)

Baud rate: 9,600 bps

Data bits: 8

Parity: none

Stop bit: 1

Flow control: none

The console, using VT100 terminal emulation, can be accessed from the RS-232 serial port or a telnet connection. The switch offers password protection for this interface. All of the following examples of the Console’s User Interface show a screen capture from a telnet session.

Page 25 of 105

When attached to the User Interface via a Telnet Session, the following must be set in order to use the arrow keys: Under the terminal pull down menu choose Properties and make sure the VT100 Arrows option is turned on.

User Interface

The switch offers a menu-driven interface.

Characteristics

There are several characteristics to the User Interface pages that are necessary to know before proceeding to use it. The TAB key or the arrow keys may be used to move within menus and sub-screens. At the bottom of every screen are some key commands available to the user for that particular screen, as well as some helpful information.

The common keystrokes and their definitions and intricacies are listed below:

ESC Return to the previous menu or screen, or abort editing

Tab Select field or move cursor

Ctrl-L Refresh the screen

Ctrl-D Log off (password enabled)

Ctrl-W Saves current configuration to Non-Volatile RAM (NVRAM)

Spacebar Toggles between possible settings for a field

Enter Select a menu item, edit a field, or accept a value after editing a field

Ctrl-X Delete a table entry
