Introduction

The master hub (and connected stack) can be managed through a PC or modem connection to the hub’s serial port, or with SNMP-based network management software such as AccView/Open. Using the configuration program, you can perform the following tasks:

•

Enable/disable any port

•

Assign backup ports

• Set threshold values

•

Configure SNMP parameters

• Display system information or statistics

•

Download system firmware

• Restart the system

Making the Connections Required for System Configuration

The diskette included with the EtherHub-16mi + contains a menu-driven configuration program. To use this program, make a direct PC or modem connection to the serial port on the master hub in the stack.

This section describes how to access the menu-driven configuration program via:

• Onsite connection

A workstation connected to the serial port on the hub.

• Modem connection

A workstation connected to the serial port of a remote hub via modems.

•

In-band connection

It also describes how to access the embedded SNMP agent over the network using AccView/Open or other third-party network management software.

Onsite Connection

Attach a PC to the serial port on the master hub. Use the null-modem cable

(and DB9 / RJ-45 converters) provided with this package, or use a null modem connection that complies with the wiring assignments shown in the back of this guide.

Modem Connection

Configure the Hub Site: Connect the master hub's DB9 serial port to the modem's serial port using standard cabling. For most modems, which use a

25-pin port, you will have to provide an RS232 cable with a 9-pin connector on one end and a 25-pin connection on the other end. You do not have to set the modem at the hub's site, because the hub will automatically configure it to auto-answer mode.

Configure the Remote Site: At the remote site, connect the PC's COM port

(COM 1~4) to the modem's serial port.

In-Band Network Connection

The EtherHub 1500 sytem can also be managed from a computer using network management software such as AccView/Open. However, prior to accessing the hub, you must first configure it with a valid IP address, subnet mask, and default gateway using an out-of-band connection.

1

EtherHub 1500 System

Note: The on-board program only provides access to basic configuration functions. To access the full range of SNMP mangement functions, you must use SNMP-based network mangement software. Accton provides Windows-based SNMP software called AccView/Open with this package. Note that AccView/Open’s Hub Manager module can be easily integrated into most third-party management platforms.

Starting the Configuration Program

Insert the distribution diskette provided with your EtherHub-16mi + into the PC's floppy drive.Then activate the EtherHub 1500 System Configuration Program as described below.

Note: 1. When using a PCMCIA modem connection, add the following entry to your config.sys file: “device=cardtalk.sys /A /Com3IRQ=4”. If your PC has a PCMCIA modem or multi-I/O card, set the proper IRQ by typing "EH15SCP/i [irq #]".

2. Help is available by entering "EH15SCP/?".

3. This program can only run under DOS, or in Windows DOS shell.

1. Type "EH15SCP" at the DOS prompt C:\>EH15SCP. Using arrow keys, select the communication port on the workstation that is connected to the hub.

Advanced Reference Guide

3. If setting up a remote connection via modems:

Select Modem Channel to open the Phone List menu as shown below, and enter the phone number and press [Enter] to start the dialing mechanism.

2. Select the appropriate option from the DCE/DTE dialog box:

2

Terminal Channel for local hookup, or Modem Channel for remote connection.

Once the connection is established, the main menu for out-of-band configuration appears as shown below.

Using Configuration Program

The EtherHub 1500 System Configuration Program allows you to define system parameters, manage and control stacked hubs and associated ports, set threshold levels, and monitor network conditions. The following table briefly describes the menu selections available for this program.

Select the Threshold command from the menu bar to define limits for the parameters monitored by the hub system. Limits can be set for the System

(entire stack), Any Hub or Any Port, or a Select Hub or Select Port. Variables to monitor include frames, bytes, collisions, frame allignment errors, CRC errors or total errors. High and low watermarks may be set. While the trigger action includes warning, warning and isolate (for hubs), or warning and disable (for ports). When any threshold is exceeded, the agent will issue an alarm to the network management station based on the selected action.

To set thresholds:

1. Open the Threshold dialog box from the menu bar.

2. Select the system component (Type: System, Any Hub, Any Port, Select Hub,

Select Port). If you choose Select Hub or Select Port, then choose the Hub

ID or Port ID using the <F2> function key.

3. Select the variable to monitor (Variable: Frames, Bytes, Collisions,

Allignments, CRCs or Total Errors). If you choose Select Hub or Select Port, then choose the variable Type using the <F2> function key.

4. Input an integer value for the low and high watermarks.

5. Select the appropriate action (Action: INACTIVE, WARNING, WARNING &

ISOLATE for hubs, or WARNING & DISABLE for ports).

6. Implement your settings by pressing the <F3> function key.

Frame

Bytes

Collisions

Alignments

CRCs

Total Errors

10

Description

The total number of frames.

The total number of bytes.

Multiple packets transmitted over a medium at the same time, making them unintelligible.

Frame alignment errors occur when the received frame is a multiple of 8 bits.

This error occurs when the cyclic redundancy check for a frame is wrong.

(The cyclic redundancy check an error-checking algorithm used to indicate frame reception errors.)

The total number of collisions, frame alignment errors and CRC errors.

Advanced Reference Guide

Event Activation - After initial event activation (crossing the high watermark), the monitored variable must reach the low watermark before another event is activated (again crossing the high watermark).

T: triggered N: not triggered

H T N T

L

Notes: 1. The rate for all values is per one second.

2. Threshold entries are stored in the agent.

Troubleshooting

Refer to the Quick Installation Guide for a more detailed listing of troubleshooting procedures. However, if you have trouble making a connection via SNMP network management software, then please refer to the following section.

Network Management Access

You can access the EtherHub-16mi + from anywhere within the attached network. However, you must first configure it with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the SNMP agent (with network management software such as AccView/Open), check to see if you have a valid network connection. Then verify that you entered the correct IP address from your location. Also, be sure the port through which you are connecting to the hub has not been disabled. (See the Control Menu on page 7.) If it has not been disabled, then check the network cabling that runs between your management site and the stack.

Pin Assignments for Serial Port Connections

DB9 Serial Port Pin Description

The DB9 serial port on the back panel is used to connect the hub to a management device. The configuration program can be accessed from a PC, or from a remote location via a modem connection. You can use the management port to configure port settings (e.g., enabled or disabled), or to update device firmware. The pin assignments used to connect various device types to the hub's management port are provided in the following tables.
