Start Guide

Before you start installing the

SPSOB

Fast Ehtemet Hub, verify that the package contains

the following items:

SP508B

Fast Ethernet hub

AC-DC Power Adapter

This User’s Manual

Please notify your sales representative immediately if any of the aforementioned items is

missing or damaged.

Overview

The

SP508B

Fast Ethernet

hubis

a standard 1

OOBasc-TX

hub that meets all IEEE

802.3~

Ethernet Standards. Fast Ethernet hub is a cost-effective solution for easing your network

congestion problem on existing 1

OBase-T

network, it offers a

seam.Lcss

migration path to

OOMbps

and multiplies the network performance up to factor of ten. This increases the

overall network transmission and improves the network cffrcicncy to accommodate

today and future high-bandwidth applications, such as multimedia, imaging and

CAD/CAM, etc.

Installation

The installation procedures arc as below:

Use CAT. 5 UTP cable,

connect

hub to workstations.

2. Repeat the above step, as needed for each

W-115

port to be connected to a

OOBase-

TX device.

’

/MPR’

can uplink to an upper level hub’s DTE port. Hubs cascading can be up to

two-level hubs.

4. Verify that the voltage of AC power is correct and insclt AC adapter cable’s plug into

power jack. Then, plug AC power adapter to the AC outlet.

Front Panel Utilization

The front panel of the

SPSOSB

Fast Ethernet Hub is shown below: The first row of the

LEDs

is active as utilization indicators for monitoring the network

trafflce.

(I%,

6%,

12%,

25%,

50%,

75% on the panel respectively).

Troubleshooting

Example

Collision LED is blinking and only one UTP port is active:

>ctL‘ctivc

port

0Defective twisted-pair wire or connector

l<samplc

2: Link/Active LED is

offat

any UTP port:

[]

Faulty node or wiring connection (when the

RJ115

plug is inserted into

the STP RJ-45 jack, a clicking sound should be heard)

0No Link signal came

from

the remote node/site

Example 3: Link/Active LED is steadily on and not blinking:

0Faulty node (station) or UTP cable

0Defective UTP port

Example 4: Partition LED is on with port failed:

UTP

cable is improperly connected at both ends

0Faulty port/node or wiring connection

Example 5: Class II Hub connection:

10013ase-TX

network is up to two-level repcaters

0Hub to Hub cable is 5 meter

Multiple Hub Connection

A standalone hub supports hub to 8 twisted-pair devices. IEEE

802.3~

OOBase-TX

Class II hub can bc connected up to two-level network.

more than two hubs arc

connected, select one hub as level

hub and install all other hubs (as

level

2) to it. The

File Server/Host is connected to level 1 hub. Following this approach, it minimizes the

number of hubs in any one path improves network efficiency to
