CHAPTER 2

NETWORK REQUIREMENTS

This chapter contains general networking guidelines. Before attempting to use the 8H02-16 or to install a Fast Ethernet Interface Module (FE-100TX or FE-100FX), review the requirements and speciﬁcations outlined in this chapter.

2.1 NETWORK REQUIREMENTS

The network installation must meet the guidelines included in this chapter to ensure satisfactory performance of this equipment. Failure to follow these guidelines may produce poor network performance.

Refer to the following sections that apply to your speciﬁc network conﬁguration.

2.1.1 10BASE-T Twisted Pair Network

When connecting a 10BASE-T twisted pair segment to any of the 8H02-16 ports (Interfaces 1 through 14), ensure the network meets the following requirements:

Length

The IEEE 802.3 standard for 10BASE-T requires that 10B ASE-T de vices transmit over a 100 meter (328 foot) link using 22–24 AWG Unshielded Twisted Pair (UTP) wire. However, cable quality largely determines maximum link length. If you use high quality, low attenuation cable, you can achieve link lengths of up to 200 meters. Cable delay limits the maximum link length to 200 meters.

NOTE

8H02-16 User’s Guide 2-1

Losses introduced by connections at punch-down blocks and other equipment reduce total segment length. For each connector or patch panel in the link, subtract 12 meters from the total length of the cable.

Chapter 2: Network Requirements

Impedance

Cabletron Systems 10BASE-T twisted pair products work on twisted pair cable with 75 to 165 ohms impedance. UTP cables typically have an impedance from 85 to 110 ohms. Shielded twisted pair cables, such as IBM Type 1 cable with an impedance of 150 ohms may also be used.

Temperature

Multi-pair PVC 24 AWG telephone cables typically have an attenuation of approximately 8–10 dB/100 m at 20°C (68°F). The attenuation of PVC insulated cable varies signiﬁcantly with temperature. At temperatures greater than 40°C (104°F), use plenum-rated cable to ensure that attenuation remains within speciﬁcation.

2.1.2 100BASE-TX Twisted Pair Network

The 8H02-16 with an FE-100TX installed in ports 15 or 16 provides an RJ45 connection that supports UTP cabling. The device at the other end of the twisted pair segment must meet IEEE 802.3u 100BASE-TX speciﬁcations for the devices to operate at 100 Mbps. Use Category 5 UTP cabling for networks operating at 100 Mbps. Use Category 3, 4, or 5 UTP cabling for networks operating at 10 Mbps.

NOTE

The 8H02-16 with an FE-100TX installed is capable of operating at either 10 or 100 Mbps. The FE-100TX senses the speed of the other device and adjusts its speed accordingly.

When connecting a 100BASE-TX twisted pair segment to port 15 or 16 with an FE-100TX interface module, the network must meet the following requirements:

Length

The IEEE 802.3u standard for 100BASE-TX requires that 100BASE-TX devices be capable of transmitting over a 100 meter (328 foot) link using Category 5 UTP cable.

The IEEE 802.3 standard for 10BASE-T requires that 10B ASE-T de vices be capable of transmitting over a 100 meter (328 foot) link using Category 3, 4, or 5 UTP cable.

2-2 8H02-16 User’s Guide

Network Requirements

Propagation Delay

Propagation delay is the amount of time it takes data to travel from the sending device to the receiving device.

Total propagation delay allowed for a 100B ASE-TX (100 Mbps) network is 256 bit times or 2.56 microseconds (2.56 µs). If the total propagation delay between any two nodes on a 100BASE-TX network exceeds

2.56 µs, then use bridges or other devices to further segment the network. Total propagation delay allowed for a 10BASE-T (10 Mbps) network is

256 bit times or 25.6 µs. If the total propagation delay between any two nodes on a 10BASE-T network exceeds 25.6 µs, then use bridges or other devices to further segment the network.

Temperature

The attenuation of PVC insulated cable varies signiﬁcantly with temperature. At temperatures greater than 40°C (104°F), use plenum rated cables to ensure that cable attenuation remains within speciﬁcation.

2.1.3 100BASE-FX Fiber Optic Network

Ports 15 and 16 of the 8H02-16 support the Cabletron Systems FE-100FX ﬁber optic interface module. The FE-100FX meets the IEEE 802.3u standard. When connecting a ﬁber optic segment to the 8H02-16, the network must meet the following requirements:

Cable Loss

T est the ﬁber optic cable with a ﬁber optic attenuation test set adjusted for an 850 nm wavelength. This test veriﬁes that the signal loss is within an acceptable level. The maximum loss for a multimode cable is 11.0 dB.

Fiber Optic Budget and Propagation Delay

Determine the maximum ﬁber optic cable length by calculating the ﬁber optic budget delay and total network propagation before ﬁber optic cable runs are incorporated in any network design.

Fiber optic budget is the combination of the optical loss due to the ﬁber optic cable, in-line splices, and ﬁber optic connectors.

8H02-16 User’s Guide 2-3

Chapter 2: Network Requirements

Propagation delay (collision delay) is the amount of time it takes data to travel from the sending device to the receiving device. Total propagation delay allowed for the entire network is 256 bit times (2.56 µs). If the total propagation delay between any two nodes on the network exceeds

2.56 µs, then use bridges or other devices to further segment the network.

2.2 100BASE-TX NETWORK CABLE LENGTHS

This section details the maximum network cable lengths speciﬁed by the IEEE 802.3u standard. As stated in the pre vious sections, the physical size of the network is limited primarily by propagation delay. The total propagation delay cannot exceed 256 bit times or 2.56 µs.

A 100BASE-TX/FX network might use all copper (UTP) links, all ﬁber links or a combination of both. The maximum length of any segment is determined by the types and combination of links and by the type of repeater (if any) between segments. IEEE 802.3u standards specify two repeater classes (Class 1 and Class 2) and the maximum cable lengths for each media type.

If this device is being installed in a 100BASE-TX/FX environment with repeaters, use the repeater instruction manual to determine the maximum cable lengths when laying out your network.

UTP Maximum Cable Lengths

An Unshielded Twisted Pair copper segment in a 100BASE-TX environment may be no more than 100 meters in length.

The maximum length of a UTP segment may be no more than 100 meters.

CAUTION

Multimode Fiber Cable Lengths

The maximum length of a 100BASE-FX segment may be no more than 412 meters between Data Terminal Equipment (DTE to DTE) in half duplex mode or 2 km (DTE to DTE) in full duplex mode.

4. Repeat step 2, above, until all connections have been made.

3.5.2 Connecting a UTP Segment to the FE-100TX

An FE-100-TX installed in port slot 15 and/or 16 is often used to provide a connection between the 8H02-16 and a bridge, router, or switch. Usually, in this conﬁguration, a “straight-through” cable is used and the Fast Ethernet Interface Module crossover switch shown in Figure 3-7 is set to “not crossed over.”

Normally, when connecting devices to like devices, crossing over of the transmit and receive pairs must occur. Before connecting a segment to the FE-100TX, check each end of the segment to determine if the wires have been crossed over for the proper connection.

A schematic of a crossover cable is shown in Figure 3-6. If the wires do not cross over, use the switch on the FE-100TX to internally cross over the RJ45 port. Figure 3-7 shows how to properly set the FE-100TX crossover switch.

Current Operational Mode (Read-only)

This ﬁeld displays the current operating mode of ports 15 and 16. Depending on whether a 100Base-FX or 100Base-TX is installed, this ﬁeld displays the following:

• With a 100Base-FX interface: 100Base-FX or 100Base-FXFD (full duplex)

• With a 100Base-TX interface: Unknown, 10Base-T, 10Base-TFD (full duplex), 100Base-TX, or 100Base-TXFD (full duplex).

Desired Operational Mode (Selectable)

This ﬁeld allows the user to select the desired operational mode for an interface in port 15 or 16. The ﬁeld toggles between 100Base-FX and 100Base-FXFD (full duplex) when an FE-100FX is installed. Section 6.14.1 describes how to conﬁgure a port with an FE-100FX.

6-40 8H02-16 User’s Guide

High Speed Interface Conﬁguration Screen

NOTE

In normal operation, the port with an FE-100TX installed automatically establishes a link with the device at the other end of the segment without requiring user setup. However, Local Management provides the user with the option of manually conﬁguring that port.

If an FE-100TX is installed, the ﬁeld steps to Auto-Negotiation, 10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD (full duplex). In normal operation, the port with an FE-100TX installed is capable of auto-negotiating the operational mode and no further user setup is required. Section 6.14.3 describes how to conﬁgure an FE-100TX.

Advertised Ability (Selectable)

During auto-negotiation, the FE-100TX “tells” the device at the other end of the segment what its capabilities are. The capabilities of a port (15 or

16) with an FE-100TX installed are 10Base-T, 10Base-TFD (full duplex mode), 100Base-TX and 100Base-TXFD (full duplex mode). In normal operation, with all capabilities enabled, the FE-100TX “advertises” that it has the ability to operate in any mode. The Network Manager may choose to set up the port so that only a portion of the available capabilities are advertised and the others are disabled. For example, only 100Base-TX and 100Base-TXFD might be enabled so that only devices that operate at 100 Mbps can communicate with that port.

6.14.1 Conﬁguring an FE-100FX in Port 15 or 16

When an FE-100FX is installed in port 15 or 16, it must be manually set to operate in the same technology as the device at the other end of the connected segment. Section 6.14.2 provides instructions for manually conﬁguring the port with an FE-100FX interface.

In normal operation, a port (15 or 16) with an FE-100TX interface automatically establishes a link with the device at the other end of the segment and no user setup is required. Section 6.14.4 and Section 6.14.5 provide instructions for manually conﬁguring the port with an FE-100TX installed.

6.14.4 Setting the FE-100TX Operational Mode

Use this ﬁeld to set the active technology. This ﬁeld steps between Auto-Negotiation, 10Base-T, 10Base-TFD (full duplex), 100Base-TX, and 100Base-TXFD (full duplex). If Auto-Negotiation is selected, the FE-100TX automatically sets the active technology. To manually set the active technology through Local Management, proceed as follows:

1. Use the arrow keys to highlight the Desired Operational Mode field.

2. Use the SPACE bar to select the desired mode. Press ENTER. If any mode other than Auto-Negotiation is selected, the port only operates in the chosen mode and auto-negotiation is disabled.
