Ethernet SOHO Hub

Introduction

The MIL-H1100 family of small SOHO Ethernet
hubs brings unmatched flexibility to LAN
environments. These hubs provide your network
with multiple wiring connections for up to 4 or 8
unshielded twisted pair (UTP) ports.

These hubs constantly monitor each port for signal
quality and will automatically disconnect a device
producing noise or excessive collisions. The device
will automatically be reconnected when the error
condition is cleared. Data packets which exceed the
maximum legal length for IEEE802.3 Ethernet
packets are automatically truncated. This prevents a
device from blocking the network by transmitting a
continuous data stream or extra long packet. The
hubs completely retime and restore full-amplitude
waveforms for each retransmitted packet. A full­length preamble is also generated, insuring packet
integrity across the network. Compact, light and
robust, the 4- or 8-port hub provides the ideal
solution for your small, medium, or large 10Base-T
LAN environment. Now you can truly take
advantage of 10Base-T in your network, and your
installation will be an easy task.

Description

The 4- or 8-port hub is easy to install and requires
no special training. You should, however, read the
following instructions carefully before proceeding
with the installation. Figure 1 and Figure 2 show
the layout of the front panel and rear panel of the
4- or 8-port hub.

Caution:

Before you begin the installation, check the AC
power line voltage used in your area. The AC
power adapter that was included with your hub
should match the power supply voltage used in
your area. Using an AC power adapter with an
incorrect AC voltage may damage your hub.

AC input power: equal to the AC power voltage
used in your area.
DC output power: 7.5 V @ 500 mA (4-port)

7.5 V @ 700 mA (8-port)

10Base-T Station to Hub Connection
Use the following procedure to connect a 10Base-T
Ethernet station to the hub.

· Make sure that the hub's slide switch is selected

to NORMAL mode for the 1st port.

· Connect one end of the cable to the 1st port of

the hub and the other end to the station, as shown
in Figure 3.

Figure 3. Connecting to Station

Interconnecting Hubs

Note the following when interconnecting two or
more hubs:

· Make sure that the primary hub's switch is set to

UPLINK mode for the 1st port and the secondary
hub's switch is set to NORMAL mode.

· Connect one end of the cable to the 1st port of

the hub and the other end to another hub, as
shown in Figure 4a and Figure 4b.
