LinkSwitch 3000 (SuperStack II Switch 3000 FX)

Product Description

The new LinkSwitch(TM) 3000 eight-port Fast Ethernet switch is the ideal solution for connecting together Fast Ethernet switches, Fast Ethernet hubs, and high-speed servers.

The switch has eight 100BASE-TX Fast Ethernet ports. There's also a downlink module slot for an optional Fast Ethernet fiber or copper downlink; an ATM downlink option will also be available. And a transceiver interface module slot lets you use any Ethernet media to connect to legacy 10 Mbps backbone LANs. Like the other LinkSwitch switches, the LinkSwitch 3000 uses state-of-the-art ASIC technology for high-performance, full-featured, price-competitive switching. The switch provides full bandwidth on all ports, and with support for up to 4,080 MAC addresses, it handles networks of virtually any size. Intelligent Flow Management (IFM) provides congestion control to eliminate data loss, and virtual LAN (VLAN) support is built into the switch's BRASICA(TM) ASIC for improved network management. Like all the LinkSwitch family switches, the LinkSwitch 3000 features plug-and-play installation and provides full SNMP management and support for Transcend® management applications. And you'll be ready for multimedia: with a simple software upgrade, the LinkSwitch 3000will support PACE(TM) technology for time-sensitive multimedia applications. For high performance and ease of use in a Fast Ethernet environment, the superior choice is LinkSwitch 3000.

3Com's BRASICA chip architecture provides 800 Mbps internal bus bandwidth for high performance Downlink module slot provides an optional seventh high-speed port for a Fast Ethernet fiber (100BASE-FX) or copper (100BASE-TX) downlink; an ATM downlink will also be available Built-in RMON support provides comprehensive information about the LANs connected to the switch ports.

Optional switched connection to legacy 10 Mbps LANs is available via transceiver interface module Operation with SuperStack components integrates LAN connections and functions, including wide area routing, fault tolerance, and redundant power .

Lanplex 2500

Product Description

The FastEthernet Module for the Lanplex 2500 offers 100 Mbps switched connection for backbone or high desktop-to-server.

This option requires version 7.0.1 on the Lanplex.

Scitex Catalog Number : 501R44473

Installation

Prior to installing the FE module, the LP2500 must be upgraded to version 7.0 or later (Scitex highly recomends using version 7.0.1, which is the latest version available today).

Software Loading

  1. In order to load Version 7.0.1 to the Switching hub you should load the software to an FTP server and then load it from to ftp server to the Flash memory of the LP2500.
  2. You can use the Ripro as an FTP server to load the software to the LP2500.
  3. Copy the software from the diskette to /tmp on the Server as follows:
    - type cd /tmp and press Enter.
    - type tar xvf /dev/fd0 and press Enter.
    - type uncompress lp2500.Z and press Enter.
  4. To verify that the file is OK use the sum command
    - type sum lp2500 and press Enter.
    The output should be:
    12041 2411 lp2500
  5. Copy the diagnostic from the second diskette to the server
    - type tar xvf /dev/fd0 and press Enter.
  6. To verify that the file is OK use the sum command
    - type sum lpx2000s and press Enter.
    The output should be:
    29157 152 lpx2000s
  7. Configure the IP address of the LP2500 (if already configured go to step 9):

  8. Configure IP Address:

  1. Check access from the Switch to the Ripro using ping command:
  1. Check access from the Ripro to the Switch using ping command:
    # ping 192.9.150.200
  2. Open telnet session to the LP2500 and login as admin

Load LP2500 software version 7.0.1

Load LP2500 diagnostic version 3.02

Configuration

  1. Follow 3com FE Module Installation Guide and install the FE module into the LP2500.
  2. Open telnet session to the LP2500 and reconfigure the IP address of the LP2500 to include the new FE interface.

NOTE: This step is very important. If you skip it the FE port will not function properly with IP traffic.

FastEthernet connection

The LP2500 FE can be connected to the following devices:

  1. Directly to a FE Adapter on a workstation/server (Ripro2100 FE adapter, SciNet PCI, Mac with 3rd party FE adapter, etc.)
    The connection between the LP2500 FE port and the FE adapter should be performed using Category 5 Twisted Pair cable.
  2. To a FE WorkGroup Hub (3com FMS 100 was tested and is recomended by Scitex) in order to share the 100Mb/s bandwidth between several stations.
    The connection between the LP2500 FE port and the FMS 100 is performed using 100BaseT cross cable.
    - As a backbone connection to an FE port on a Switching Hub (Scitex tested and recommends 3com Switch1000 and Switch3000).
    The connection to the Switch1000 & Switch3000 can be configured as FullDuplex,

NOTE: It is a essential to configure FullDuplex at both ends.

The connection to the Switch1000/3000 is carried out to the 100BaseTX Downlink Module.

NOTE: In order to use regular Category 5 cable (not crossed) the jumper on the Downlink Module should be set to MDI (the default setup).

In order to change the setting of Jumper on the Downlink module you should remove the module from the Switch (for further details follow the the 3com FE Downlink Module User Guide).
