The H638 10/100 ethernet switch creates a home network between up to
eight computers. “Plug and play” installation is easy when using the H628 data
hub. The H638 is IEEE 802.3u
100 Base-TX Fast Ethernet
compliant, IEEE 802.3 10 Base-T
compliant and has activity LEDs
for network status and diagnosis.
The H638 shares an MDI “uplink”
port with Port 1 to expand the
network using additional H638
units for systems with more than
eight devices.
Typical Installation
Wiring the H638 Switch
• Use only Category 5e unshielded twisted-pair cable for maximum
performance.
• When connecting to an H628 or a network device directly,
use straight through or crossover RJ-45 cables. All ports will
automatically detect the cable type.
• Each run to a network device should be less than 100 meters
(328 feet).
LED Indicators
• ACTIVE lights are on when a network device is connected and
fl ash when data is transmitted or received. The lights are off when
a port is not connected.
• FULL DUPLEX lights are on when a port is in full duplex mode.
The lights are off when a port is in half duplex mode and fl ash
when a collision occurs. Although some collisions are normal, too
many collisions may indicate a problem such as a faulty cable or
connection.
• 100 MBPS lights are on when a port is in 100 Mbps mode. The
lights are off when the port is in 10 Mbps mode.

Expanding the Network
Use one of the ports on the fi rst H638 and connect to the
expansion H638 using its MDI “uplink” Port 1. See below for special
instructions.
Using more than one switch
• Use only Category 5e unshielded twisted-pair cable for maximum
performance.
• When connecting two switches, use a straight through or
crossover RJ-45 Category 5e cable. Category 5 patch cords may
be used for short interconnections.
• The cable length between any two switches cannot exceed 100
meters (328 feet).
• Additional switches may be used as long as the path between
any two network devices does not exceed four switches and fi ve
cables.
• All switches used must be powered.
Declaration of Conformity
THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS
SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT
CAUSE HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY
INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE

protection against harmful interference in a residential installation. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used according to
the instructions, may cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which if found by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet other than the receiver’s outlet.
• Consult a dealer or an experienced radio/TV technician for assistance.

OpenHouse® Enclosures, Modules,
Accessories & Wall Plates
Service center
enclosures
A full line of OpenHouse® compatible enclosures,
from simple, inexpensive mounting plates to

mounted inside the cabinets.
Starter systems
RF splitters and telephone punch downs.
When it is time to upgrade, just snap this
module out and replace with one or more of
the more sophisticated units.
Data hubs
Termination blocks for the CAT-5e cables, Ethernet
switches. Bring the Internet to any room in the home. Or
create a home data network.
Telephone hubs
Connections for 1-4 phone lines to every
room. Starter hub adds RJ-31X jack for
security system dialer.
Wall plates
Wall plate systems for all rooms. The typical room gets TV and
telephone. The home offi ce wall plate adds data ports. The media
center wall plate adds satellite feeds.
Coax panels
Distribute antenna or cable TV to every room of the
house. Some models include bi-directional amplifi ers
for interactive cable systems. Some models include
modulator inputs and IR engines.
AV modulators
(for service center)
Create a new TV channel for a front door
camera. Some models feature Cat-5 input
connections.
AV modulators
(for media center)
Create new TV channels for DVD, VCR, or a satellite
receiver. These modulators sit in the media center.
Some offer true MTS stereo.
IR Accessories
Control video devices from any room.
New OpenHouse® products are added all the time.

Wiring a house for OpenHouse®
The cables in an OpenHouse® run from the various rooms of the house directly to
the service center location. (This is known as ‘home run’ wiring.)
Two types of wire are used for communication and entertainment: Cat-5, 4-UTP
(4 Unshielded Twisted Pairs) wire handles data or 1 to 4 telephone lines. RG-6
coax handles television (antenna or cable), satellite dish, cable modem, or AV
modulator signals. (An AV modulator creates new TV channels for front door
camera, DVD player, a VCR or a satellite receiver.)
We recommend the following pre-wire schemes. Run these wires from the
service center to the rooms indicated.
