HX-5
User ’s Guide
Section 1 - Introduction
The MaxT ech HX-5 is a 5-port ethernet hub compliant with the IEEE 802.3 10Base-T
standard. The five RJ-45 ports connect workstations or other devices together on
a 10Base-T network using unshielded twisted-pair cable. An additional crossover
port connects this hub to a second hub using standard UTP cable for easy network expansion. A full set of LED indicators assist in network troubleshooting.
The package contains the following items:
• Hub • Power adapter
• User’s Guide • Mounting plate and screws
Section 2 - Installation
1. Locating the Hub - Place the hub in a location central to your networked
computers, or within the maximum cable length (328 ft.) to the farthest
computer. It can be placed on a desk or it can be mounted on a wall by using
the included mounting plate and screws.
2. Connecting the Power Adapter - Insert the round end of the power adapter
cord into the hub’s DC Input connector (See Figure 1). Plug the transformer
end of the power adapter into a 120V power outlet. The hub is powered on
when this connection is made.
Note: The hub performs a self-test when it is first powered on. The power and
link LEDs (except port 1) will light. The link LEDs will go off, leaving only the
power LED on.
3. Connecting Workstations - Connect one end of an unshielded twisted-pair
cable into the network connection of a computer. Connect the other end of

the cable into an open port (1 through 5 except the crossover port) on the hub
(See Figure 1). The length of the cable must be less than 328 feet (100
meters). A proper network connection between the hub and an
active
workstation is indicated by a steady green LINK LED for that port.

daisy-chaining two or more
hubs together. The hub’s fifth
port features an additional
cross-over connection to facilitate daisy-chaining hubs using
standard UTP cable. Plug one
end of a standard UTP cable
into the cross-over port and
the other end into a regular
port (1 through 5) of a second
hub (see Figure 2). A maximum of 4 hubs can be connected together by daisychaining.
Note: The cross-over port is port number 5 with a reversed pin-out. The cross-
over port and port 5 cannot be used simultaneously.
Section 3 - LED indicators
12 LEDs (see Figure 3) show the status of the hub and its network connections.
LED Function
POWER On - Hub is powered on.
LINK/TX On - A network link is established.
(1 through 5) Blink - Data is being transmitted.
POL/RX On - Reverse polarity of cable is corrected.
(1 through 5) Blink - Data is being received.
COLLISION Blinking - Two workstations have attempted to send data at the same time.
Off - Hub is powered off.
Flash alternately with POL/RX - The port has been disconnected from
the network due to excessive collisions caused by the attached computer.
Flash alternately with LINK/TX - The port has been disconnected from
the network due to excessive collisions caused by the attached computer.

required. Maximum cable length from hub to workstation is 328' (100 m).
Appendix C - Technical Support
In the unlikely event you experience difficulty in the use of the product, or if it does
not operate as described, we suggest you: (1) check the Link status LED, (2)
check for the proper cable type (category 3), (3) check that the port has not been
disabled by the hub due to excessive collisions or (4) consult with your dealer.
