Overview 1
The Series 1000 Micro8 Hub is the ideal connectivity solution for departmental
Ethernet networks that contain 8 to 32 nodes. The Micro8 is easy to configure and
maintain, plus it is capable of built-in port management.
More importantly, the four Micro8 versions (Basic, AUI, BNC, and UTP) let you
expand your network to other configurations without sacrificing your existing network
configuration. For example, if you currently have a 10BASE-T RJ-45 backbone
network, you can easily add eight, inexpensive UTP ports by choosing the basic,
Micro8 version. In the same way, you can connect a 10BASE-5 (AUI) or a 10BASE-2
(BNC) backbone network to other configurations of your choice by selecting the
appropriate Micro8 version. You can even add a ninth 10BASE-T port with the Micro8
UTP version.
Features of the Micro8
The Micro8 supports the following features:
tEight RJ-45 ports for connecting UTP or STP cabling to workstations and servers
in a 10BASE-T network (Basic configuration)
tFront panel uplink switch that converts RJ-45 Port 8 to an uplinkable port so the
Micro8 can connect to another hub in a star topology
tOptional AUI connector for connecting to 10BASE-5 networks
tOptional BNC connector for connection to 10BASE-2 networks
tOptional UTP connector that adds a ninth 10BASE-T port
tLEDs that indicate power, port activity, collision, and link status
tLink integrity feature that automatically partitions noisy segments and detects
broken cable segments
tFull compatibility with the IEEE 802.3 10BASE-T hub specifications for
connection to shielded/unshielded twisted-pair wiring

LED Indicators
The Micro8 contains the following LEDs that monitor hub status:
tPWR, ACT, COL, and 9XLEDs that show the hubs power status (ON or
OFF), the incoming traffic on the hub (heavy, light, or no activity), and the
collision status (heavy or light activity); the 9X LED is for the optional UTP port.
tLink Status LEDsEach RJ-45 port has a Link Status LED associated with it.
These operate in the following manner:
lWhen you power up the Micro8, the Link Status LEDs light momentarily,
then turn off.
lWhen the Micro8 connects with either a powered network station or another
Micro8, the Link Status LED associated with that port lights and remains
lighted until the connection breaks.
lIf the Micro8 makes no connection, the Link Status LED does not light.
The following illustration shows the locations of the LEDs and the RJ-45 ports on the

SettingUptheMicro8 2
This chapter describes the basic requirements for setting up the Micro8, including
environmental, electrical, and spatial requirements, as well as UTP cabling
specifications. The chapter also explains how to power up the hub, how to make
a basic hub-to-workstation connection, and how to set up basic network configurations.
About This Chapter
This chapter contains information about the following topics:
tSelecting a Location
tConnecting Power
tCabling Considerations
tSetting the Uplink Switch
tSample Network Configurations
2-1

Selecting a Location
You can place the Micro8 on a level surface (a desktop or cabinet, for example) or
mount it on a vertical surface using velcro attachments. Before you select a location
for the hub, read this section to determine the necessary environmental, electrical, and
spatial requirements.
Environmental Requirements
Be sure the operating environment for the hub is within the following ranges:
tTemperature: 32 to 120F (0 to 49C)
tHumidity: 5% to 95% (non-condensing)
tAltitude: 0 to 10,000 feet
Electrical Requirements
Be sure there is a commercial power outlet within 6 feet (1.8 meters) cord distance of
the hub. If there is no outlet within this distance, use a power strip or grounded
extension cord to extend the range of the power cable. The power outlet must be a
non-switched, three-pronged, grounded outlet. The following table lists the electrical
requirements for the Micro8:
Electrical Requirements for the Micro8
Requirement Domestic International
Voltage 100 to 130 VAC 210 to 250 VAC
Frequency 60Hz 50Hz
Power 0.21 amps maximum 0.1 amps maximum
CAUTION: Do not use a three-to-two-pronged adapter at the outlet.
Doing so may result in electrical shock and/or damage to the hub.
Spatial Requirements
The hubs dimensions are 4.0 x 7.0 x 5.0 inches (HWD). When you set the hub on a
level surface, allow at least 2 inches (5.1 centimeters) on each side of the hub for proper
air circulation. If you place the hub on a level surface, the rubber feet (attached to the
bottom of the hub) help protect the surface and prevent the hub from slipping.
Setting Up the Micro8 Selecting a Location
2-2

Connecting Power
The domestic and international power connections differ for the Micro8. These
differences are described below.
Domestic Connections
To connect the Micro8 to external, domestic power, follow these steps:
1. Locate the power cord receptacles on the back of the Micro8, as shown in Figure
2-1.
2. Plug the female connector of the power cord into the power cord receptacle on the
back of the hub. Be sure the lip (a horizontal tab) on the power connector faces
the top of the Micro8, as shown in Figure 2-2:

3. Insert the three-pronged, male connector on the other end of the power cord into
a non-switched, grounded power outlet on a wall, a power strip, or a grounded
extension cord. The power outlet should be near the hub and easily accessible
(within the 6-feet cord distance).
4. When you plug in the power cord, all LEDs on the front panel momentarily light
to confirm that the hub is operating correctly.
Note: When you power down the hub, disconnect the
three-pronged male connector from the power outlet on the wall,
power strip, or extension cord. DO NOT disconnect the female
connector from the power cord receptacle on the hub as this may
cause a power surge that could damage the hub.

International Connections
To connect the Micro8 to external, international power, follow these steps:
1. Place the international power transformer on a flat surface.
2. Plug the female connector on the power transformer cable into the power
receptacle in the back of the Micro8. Be sure the lip on the power connector faces
the top of the Micro8 (as illustrated for domestic connections in Figure 2-2).
3. Plug the female end of an IEC power cable into the three-pronged, power
transformer receptacle, as shown in Figure 2-3:
4. Insert the three-pronged male connector on the IEC power cable into a grounded
power receptacle on the wall, a power strip, or a grounded extension cord.

Cabling Considerations
This section outlines twisted-pair wire specifications and describes how to make a
simple direct connection between an Micro8 and a workstation.
Twisted-Pair Wire Specifications
To ensure long-term LAN reliability, be sure that the twisted-pair wiring meets the
following minimum specifications. If the wiring does not meet the following
requirements, you may need to install new twisted-pair wiring.
tThe wiring must be shielded or unshielded twisted-pair (STP/UTP).
tTwo pairs of wiring are required.
tDepending on building codes, different insulation materials may be required.
Plenum-rated or TEFLON-coated wiring may be required in some areas.
tThe UTP wire should meet the following specifications:
lSolid copper
lNominal capacitance: Less than 16pF/foot
lNominal impedance: 100 Ohms
lNominal attenuation: Less than 11.5db
lWire gauge: Between 18 and 26 AWG (Most telephone installations use
24-gauge wiring.)
tThe wiring has a maximum distance requirement of 100 meters which includes
all cross-connect wire, wire in the walls, and any drop cables from wall plates to
workstations (see the next section to determine the proper length). Maximum
distances may be less for UTP cable run underground, in conduit, or in large cable
bundles.
tThe wiring must be in good condition and the insulation should not be frayed or
worn.
CAUTION: Never use gray satin station cable for connecting an
Micro8. This flat cable, typically used for connecting telephones to
wall jacks, is incompatible with 10BASE-T systems.
The Micro8 is compatible with all AT&T Type D wiring (D-Inside wiring) and AT&T
PDS wiring. You can also use IBM Type 1 wiring (with two inside conductors).
Setting Up the Micro8 Cabling Considerations
2-6

Two types of D-Inside wiring will work with the hub:
tDW8Uses stranded wires and is relatively flexible; is best for shorter runs (less
than 50 feet) within the same room
tD8WUses solid conductors and is less flexible; is best for longer runs through
ceilings and/or walls
A modular cord is D-Inside wiring with RJ-45 plugs on each end. The connection
between a hub and a workstation consists of four pairs of straight-through, D-Inside
wiring (the hub uses only two pairs), as shown in the following figures:
In this cable, the wire connected to Pin 1 must be twisted with the wire connected to
Pin 2, and the wire connected to Pin 3 must be twisted with the wire connected to Pin
6, as shown in Figure 2-3. Pins 4, 5, 7, and 8 are reserved for telephone and other
services.
