5 Ov ervie w of Hub Management Hubs themselves are rarely the cause of problems on the network. However, since hubs are the center point for many devices on the network, it’s a good place to start looking for problems. There are four categories of management tasks: • Configuring the hub or stack of hubs.
6 Mana ging m ultiple hubs To manage multiple hubs, you must stack them using Intel Cascade Cables. 100 Mbps 100 Mbps 10 Mbps 10 Mbps Connecting hubs with Intel Cascade Cables allows you to manage both 10 and 100 Mbps hubs with a sin g le Mana g ement Module.
7 Collision domain assignments All hubs running at the same speed in the stack belong to the same collision domain. In the example below, all devices (PCs, print servers, and so on) connected to hubs 1 and 2 share 100 Mbps of bandwidth. All devices connected to hubs 3 and 4 share 10 Mbps of bandwidth.
8 LCD men u tree IP address: 000.000.000.000 Subnet Mask: 000.000.000.000 Default Gateway: 000.000.000.000 Stats Config Manual BootP Traps About IP Addr= Subnet= MAC Addr= Version= RS232= Help Press Stats to view domain or port statistics. Press Traps to view SNMP trap messages.
9 Using the LCD Navigating The Management Module has four buttons and an LCD display, which you can use to display information about your network or to make changes to the module, hub, or stack.
10 Changing the LCD contrast You can change the contrast so the display is viewable from different angles. For example, if the management module is located in a hub at the top of a rack. • Make sure the Main menu is displayed with the Stats item flashing.
11 3 Use the arrow keys to step through the different stats —packets, collisions, auto-partitions, alignment errors, frames too long, runts, very long events, rate mismatches, late collisions, FCS errors, short events. While viewing a statistic, you can update by pressing .
12 Text: User-defined text set via SNMP through LANDesk Network Manager or Device View for Web. Up to 32 characters can be displayed on the LCD. Address: The current IP address of the Management Module. 4 Choose Yes if you want the management module to sleep now or No to return to the Config menu.
13 Using the Console Manager Accessing with the serial port 1 Use the enclosed null modem cable to connect the serial port of your PC to the serial port of the Management Module. 2 Open a terminal emulation program (such as HyperTerminal in Microsoft Windows* 95).
14 Accessing with T elnet Telnet lets you access the Management Module in-band (over the network). To use Telnet: 1 Make sure an IP address is assigned to the Management Module. See pages 11 or 19 for instructions. 2 Open a Telnet application. In Windows 95, select Run from the Start Menu.
15 Navigating See below for navigation tips. On the top screen (see the next page) you can press the number of the menu item to select it. For example, selecting 1 will display the System Configuration screen.
