1.3 Front Panel Description

From left to right, the front panel contains the following: Power and port LEDs; 24 10/100 ports; 2 optional module slots; and a console port.

The switch is field upgradeable for use with 100BaseeFX, 1000BaseSX, 1000BaseX GBIC or 10/100/1000BaseT modules.

1.4 Management and Configuration

There are three different methods by which a user can manage the switch: web, console/telnet, or with SNMP software. You may prefer using a web browser to be able to configure the switch from any local or remote computer, via the network, or you may wish to use a console for out-of-band management. SNMP is an advanced management application, and is mostly automatic, giving you the information without having to go through an interface step by step (Note: The switch is shipped with BootP support. See Appendix F for more information on setting up BootP).

1.4.1 Console Interface

Users can access the switch in a more traditional way by connecting a PC or terminal to the console port or by telnet across the network. The menus are organized in a manner similar to the web-based interface. A detailed description can be found in Chapter 3 Configuration. Users must use a console connection to form a stack (multiple units sharing one IP address). See Chapter 2.11 Using the Stacking Feature for more details.

1.4.2 Web-Based Interface

With Internet access, users can link directly to the local switch’s home page. Users can configure the switch, monitor the LED panel, and display statistics graphically. A detailed description can be found in Chapter 5. Web-Based Interface.

1.4.3 SNMP Management

Since the switch supports SNMP, users can manage the switch with an SNMP-compatible management station running platforms such as HP OpenView. It also supports a comprehensive set of MIB extensions along with MIB II, Ethernet MIB, the 802.1D bridge MIB, and 4 groups of RMON. Please see Chapter 3, or Chapter 6. SNMP Management for more information.

2. After the unit is connected to the network, it can be configured for management capabilities (see the following chapters for information on configuration).

2.6.1 10/100BaseT Ports Cabling Procedures

The 24 10/100 ports on the IntraCore 3524 allow for the connection of 10BaseT or 100BaseTX network devices. The ports are compatible with IEEE 802.3 and 802.3u standards.

Important: The IntraCore 3524 must be located within 100 meters of its attached 10BaseT or 100BaseTX devices.

Use the following guidelines to determine the cabling requirements for your network devices:

Connecting to Network Station: Category 5 UTP (Unshielded Twisted-

•

Pair) straight-through cable (100 meters maximum) with RJ-45 connectors Connecting to Repeater/Hub/Switch’s Uplink port: Category 5, UTP

•

straight-through cable (100 meters maximum) with RJ-45 connectors

Note: There is no uplink port on this switch. All 10/100 ports on this switch are auto-sensing MDI/MDI-X. This advanced feature means that the 10/100 ports will automatically determine whether the device at the other end of the link is a hub, switch or workstation, and adjust its signals accordingly.

Although 10/100BaseT requires only pins 1, 2, 3 and 6, Asanté strongly recommends cables with all 8 wires connected as shown in Table 2-1 below.

1000BaseT requires that all four pairs (8 wires) be connected correctly, using Category 5 or better Unshielded Twisted Pair (UTP) cable (to a distance of 100 meters). Table 2-1 shows the correct pairing of all eight wires.

2.7 Setup

The following sections describe the steps for setting up the switch for basic configuration, and putting into place basic security measures (setting up password protection, changing from the default IP address and configuring the SNMP host table).

In order to configure the switch, you will need to connect to it through a console (out-of-band management), through your web browser, or through a telnet session.

2.7.1 Connecting to a Console

When attaching a workstation to the device, a standard straight-through CAT5 cable may be used, even when the workstation is attached via a patch panel. No crossover cable is needed with the MDX/MDI ports. It is recommended that the switch be kept off the network until proper IP settings have been set.

To connect the switch to a console or computer, setup the system in the following manner:

1. Plug power cord into the back of unit.

2. Attach a straight-through serial cable between the RS232 port and a COM port on the PC.

3. Setup a HyperTerminal (or equivalent terminal program) in the following manner:

• Under the

2.11 Using the Stacking Feature

The 3524 v.1.1 offers a stacking feature that allows the user to stack up to eight units, all sharing one IP address of the master switch (unit #1). This is an efficient and cost-effective way to add ports as needed. The following lists the characteristics of stacking that the user needs to be aware of:

• Uses any physical media supported by IC 3524: copper or fiber, Fast Ethernet or Gigabit Ethernet (see the stacking kit {sold separately} shown below); or a special, cost-effective Stacking Kit (available Q2-02, not shown)

Stacking Kit

• All stacked units are managed through connection to the master switch, via console, telnet or web interfaces

: While the user may manage the stack via console, telnet or web interface, the initial

Note

formation of the stack may only be done by connection to a console.

• The switches need no extra software, but they must all have the 1.1 firmware installed (see Chapter 3.14 for firmware upgrade instructions)

Follow the steps below to install (build) a stack:

1. Physically stack the units, in an equipment rack, or on a flat, stable surface (Asanté recommends that the stack is formed from the bottom up for ease of adding additional units).

2. Units are connected via the Gigabit ports (see section 2.4 for instructions on installing the optional modules). Starting with the first unit in the stack (the bottom unit, in the photo below), connect the Ethernet cable from Gigabit port #26 to the Gigabit port #25 of the next unit and continue the connections to the last unit in the stack. The result is a stack with n x 24 10/100 ports and 2 Gigabit ports, where n is the number of units in the stack (up to eight).

3. For stacking operation, the stacking feature must first be enabled on each unit (by default, stacking is disabled). Establish a console connection to the first unit. Type k in the Configuration Menu to access the Stacking Management menu. Type t to toggle the switch from “disabled” to “enabled”. Repeat for all remaining units.
