General Description

LANplex2500

The LANplex2500 manufactured by the 3Com Corporation, is a SNMP-managed (Simple Network Management Protocol) FDDI to Ethernet switching hub. It provides as a basic unit, eight SW (switched) 10Base-T Ethernet ports, and one high speed FDDI Dual Attach port, these can be expanded to a maximum configuration of sixteen SW (switched) 10Base-T Ethernet ports, and two high speed FDDI Dual Attach ports. The LANplex 2500 can be used for connecting a Ripro Server with a Ripro FDDI Board (#501R44011), SciNet FDDI stations (Whisper with FDDI board) up to sixteen Ethernet segments. In the future it will also connect a Ripro Server which has a SciNet FDDI board.

Each Ethernet segment can be connected to a high end workstation in order to provide the station with full Ethernet bandwith (10Mbit/sec) or can be connected to a workgroup hub (TP/8i) that will share the Ethernet bandwidth between the workgroup stations. Ethernet clients can be SciNet clients (PTOP) and/or standard protocol clients (AppleTalk, TCP/IP, IPX, etc.)

For high-traffic local LANs, the LP2500 switching hub improves local network throughput and client/server performance, easily and affordably. The two high-speed fiber FDDI ports connect to file servers to provide 100Mb/sec (Mbit per second) connectivity or connect to high end workstations with an FDDI interface or connect as a network backbone.

LinkBuilder TP/8i

The LinkBuilder TP/8i is a stand-alone Ethernet repeater with eight ports for connection to 10Base-T networks. The LinkBuilder TP/8i is used in conjunction with the LANplex2500 as a workgroup hub, to expand an existing network, which can connect up to seven workstations and also connects to a switched Ethernet port of the LANplex2500.

Logistics

The following kits are used when installing the LP2500 with an FDDI DA port in the Ripro Server:

Note:
Both LP2500 units are upgradable to sixteen Ethernet ports and two FDDI Fiber Dual Attach ports using the modules (item# 3, 4).
Item# 2 has an extra (redundant ) power supply.

Installation Procedure

These installation instructions deal only with the necessary information to install and activate the unit and connect to Scitex Systems. For further details refer to the following booklet which is supplied by the manufacturer together with each unit:
- LANplex2500 Getting Started.
- LinkBuilder TP/8i User Guide, 3C16181.

Locating the LP2500 and TP/8i

• Can be either wall mounted, free standing or mounted in standard 19-inch rack equipment. Scitex requires installing the communication devices only in a 19-inch rack.
• Ensure that there is adequate access for all maintenance purposes and free air flow.
• Make sure that the cabling is away from all sources of electrical noises, power lines and lighting fixtures.

Installing an Option Module

The LP2500 is supplied with an Ethernet option module and an FDDI module, these are not installed.

To install these modules and additional modules refer to LANplex 2500 Getting Started, Chapter 3 Installing Option Modules.

Power up Diagnostics LP2500

The LP2500 runs diagnostics software at power up. The system processor LEDs indicate whether the LP2500 is functioning properly.

Module Diagnostics

When diagnostics run on a particular module the Port Status LEDs are lit

(see Figure 1. LANplex2500 Back Panel slot 3 and/or slot 4 below).

Connecting to Ethernet

There are eight Ethernet ports (1-8) with shielded RJ45 data sockets suitable for direct connection to a workstation using twisted pair cable (Scitex recommends only using infrastructure cable 4x2W (wall cable) and patch cable ,both must comply with category 5 standard), or connection to a number of stations connected to workgroup hub (TP/8i). These ports are implemented as MDI-X (media dependant interface crossover) to enable the direct connection with a straight through cable.

Connecting to LinkBuilder TP/8i

1. To connect the LinkBuilder TP/8i to a LP2500 Switching Hub or to anotherLinkBuilder TP/8i use port 8 with the MDI switch on the LinkBuilder TP/8i pushed-in.
2. Connect the one side (male) of the RJ45 patch cable to a port of the LP2500 Switching Hub and the other side of the cable to port number 8 of the LinkBuilder TP/8i.
3. To connect the LinkBuilder TP/8i to a workstation use the ports with the RJ45 (male) connector to connect directly to the workstation (through a patch panel located in the communications rack).

Note: The MDI (Media Dependent Interface) controls the operation of port 8. Refer to Installing the TP/8i, MDI Switch.

Figure 2. Connecting up the LP2500 and TP/8i

Connecting to FDDI

Each LP2500 Switching Hub can support:

• Two FDDI SA connections or one FDDI DA connection, by installing one FDDI board.
• Four FDDI SA connections or two FDDI DA connection, by installing two FDDI boards.

Connecting the Terminal to a Serial Port

The Serial Port provides RS-232 connection to a local terminal, modem or workstation (laptop running terminal emulation program).

1. Use the RS-232 cable (#504G34023 or #504G34023A) to connect the serial port on the LP2500 to the terminal serial port on your laptop (instead of your mouse).
2. Do not power ON the LP2500.

IP Addressing

The following is the recommended structure for Scitex IP addresses:

Examples

• Y-is determined by the Network communication board on the particular server. 192.9.110.25- is a Mac connected to the Second Ethernet board on Ripro1.
• 192.9.150.125- is a Whisper connected to FDDI through the Switching Hub.
• The first Mac connected to ent0 will have an address of 192.9.100.21.
• The first PS/2* connected to the Ripro Server via the FDDI adapter and Switching Hub will have an IP address of 192.9.150.75.
• The first Whisper connected to ent1 will have an address of 192.9.110.120

Setting Up the IP Address

1. At the Administration Console main menu type ip.
2. At the ip menu type interface.
3. At the interface menu type define.
4. Enter the IP address of the interface.

5. Press q to quit.

Note: Where the IP addresses are set according to Scitex defaults use the above example. Where the IP addresses are set according to the site network configurations, use the site IP addresses for the LP2500 configuration. The site administrator should provide you the IP address, Network Mask and Gateway Address.

LP2500 Network Configurations

The following diagrams illustrate the different configurations using the LP2500.
