receive status of each twisted pair port. PWR and COL

indicators show the status of the hub as whole.

Product Features

üCompliance to IEEE 802.3 10BASE-T/2 standard.

üAutomatic paritioning function of each port to isolate

network failure.

üEthernet connections support Category 3 or better

LED Indicators

Power (PWR): This indicator lights gr

een when the hub

is receiving power, otherwise, it is off.

Collision (COL): This indicator indicates data collisions

the respective Ethernet

segments of the

hub. Whenever a collision is dete

cted, the

respective COL indicator will briefly

blink amber.

Link/Receive:

(LINK/RX)

This indicator green when the port is

connected to a Ethernet station

, If the

station to which the hub is connected is

powered off, or if

there is a problem with

the link, the LED

will remain off. And the

indicator blinking green when the data

will be received to all other connected

ports.

BNC: This indicator blinking green when the

data is transmitted.

Rear Panel Indicators

Twisted-pair Jacks

Use these jacks connect stations to the hub. These are MDI-X

(Medium Dependent Interface, Cross-Wired) jacks, which

means you can use ordinary stright-through twisted-pair cables

to connect user mechines and servers to the hub through them.

If you need to connect another device with an MDI-X jack,

such as another hub or an Ethernet switch, you should use a

crossver cable, or make the connection using the Uplink jack.

Uplink Jack

The Uplink jack is an MDI-II jack, which means you can

connect the hub (or a hub stack) to a device with an MDI-X

port using an ordinary straight-through cable, making a

crossover cable unnecessary.

Port1 and the Uplink port is really the same port, except thar

their pinouts are different. Do not use both Port-1 (1X) and

the Uplink port at the same time.

Power Jack

For the External power adapter.

Installation

Installing the Hub

The site where you install the hub may greatly affect

its performance. When installing, consider the

following pointers:

Install the hub in a fairly cool and dry place, for

the acceptable temperature and humidity operating

ranges.

Install the hub in a site free from strong

electromagnetic field generators (such as motors),

vibration, dust, and direct exposure to sunlight.

Leave at least 10 cm of space at the front and rear

of the hub for ventilation.

Install the hub on a sturdy, level surface that can

support its weight. When installing the hub on a

level surface, attach the rubber feet to the bottom of

each device. The rubber feet cushion the hub and

protect the hub case from scratches.
