3 Hardw a r e Installation and Netw ork T opology Over view The Intel Express 100BASE-TX Switching Hub is a 5-port Fast Ethernet switch featuring five 100BASE-TX ports and two slots for optional 100BASE-TX or 100BASE-FX media adapters. Each 100 Mbps port supports a Fast Ethernet segment, up to a total of 1024 cached nodes for the switch.
4 CHAPTER 1 Intel Express 100BASE-TX Switching Hub Security features include the creation of custom filters and virtual networks (VLANs). You can define any custom filter based on multicast/broadcast, source port, destination port, and destination address.
5 Hardware Installation and Network Topology CHAPTER 1 Installation and Setup 1 Install the switch in a rack or on a shelf. For rack placement, connect the switch to a 19-inch rack using the enclosed rack mount brackets.
6 CHAPTER 1 Intel Express 100BASE-TX Switching Hub Using the Switch The switch requires minimal user intervention. It automatically learns the addresses of new stations as they appear, and will relearn addresses dynamically if the network is reconfigured.
7 Hardware Installation and Network Topology CHAPTER 1 Mgmt Management. Lights when the management agent checks the port (normally, every two seconds). Link Link. When solid, indicates a connection is established. If the Link LED is off, check for loose cable connections.
8 CHAPTER 1 Intel Express 100BASE-TX Switching Hub Cab ling Requirements Incorrect cabling is often the cause of network configuration problems. It’s important that you understand cabling requirements before connecting Fast Ethernet devices to the switch.
9 Hardware Installation and Network Topology CHAPTER 1 Straight-thr ough vs. cr osso ver cab les Ports on the switch are wired MDI so you can use a straight-through cable when connecting to a Fast Ethernet repeating hub port, which is usually wired MDI-X.
10 CHAPTER 1 Intel Express 100BASE-TX Switching Hub T ypical Configurations Configuring the 100 Mbps w orkgroup en vir onment In the 100 Mbps environment, workgroup clients should be connected to a 100 Mbps hub such as the Intel Express 100BASE-TX Stackable Hub.

15 2 Conf igur ing and Managing the Switch You don’t need to read this chapter unless you want to change the Express Switching Hub’s default configuration (see Appendix A for a list of defaults) or intend to manage the switch. The switch is ready to go simply by plugging it in and turning the power on.
16 CHAPTER 2 Intel Express 100BASE-TX Switching Hub Accessing the Console Manag er The Console Manager software is contained in the switch’s nonvolatile RAM (NVRAM); you don’t need to install any software.
17 Configuring and Managing the Switch CHAPTER 2 Using the Console Manag er The Console Manager provides an out-of-band (not on the network) connection to the switch. Use the Console Manager to • assign an IP configuration to the switch. • configure the ports.
18 CHAPTER 2 Intel Express 100BASE-TX Switching Hub Commands sometimes have parameters that determine how they’re saved and when they’re implemented. Some are changed in • the running database so that the new value is used immediately (the run option).
19 Configuring and Managing the Switch CHAPTER 2 Console Mana g er command gr oups The Console Manager has several categories of commands: • Console commands : help, banner, serial line setup, console parameters setup. • System commands : system status, reset commands, download commands, and system debug commands.
20 CHAPTER 2 Intel Express 100BASE-TX Switching Hub NOTE You must have a point-to- point connection to establish a full-duplex connection (shared hubs/repeaters/ concentrators aren’t capable of full duplex). Additionally, both points of the connection must be configured for full duplex.
