Connecting Workstations and Other 
Equipment to Your Hub

WARNING:

 Please read the ‘Important Safety 

Information’ section before you start.

WARNHINWEIS: 

Bitte lesen Sie den Abschnitt 

‘Wichtige Sicherheitsinformationen’ sorgfältig durch, 
bevor Sie das Gerät einschalten.

AVERTISSEMENT: 

Veuillez lire attentivement la 

section “Consignes importantes de sécurité” avant de 
mettre en route.

CAUTION:

 The equipment connected to the Hub 

must be set to operate in auto-negotiate or half 
duplex mode.

Connecting workstations and other equipment to your Hub 
is easy. To connect a workstation to any of the Hub’s ports, 
use a ‘straight-through’ TP cable. Refer to “Twisted Pair (TP) 
Cables” on page 10 for further information.

If you are using port 5 (Dual Speed Hub 5) or 8 (Dual 
Speed Hub 8) or 16 (Dual Speed Hub 16) to connect a 
workstation, ensure the Uplink/Normal switch is set to 
Normal (out).

TP cables are very easy to use. To connect a cable, simply 
slot the connector into the appropriate RJ-45 port. When 

the connector is fully in, its latch locks it in to place. To 
disconnect the cable, push the connector’s latch in and 
remove it.

The Hub detects all port connections, so you can start using 
your network immediately. If you need more ports, simply 
add another OfficeConnect hub.

Connecting Another OfficeConnect Hub

You may wish to connect another OfficeConnect hub to 
your Dual speed Hub. Alternatively, you may wish to add 
your Hub to an existing 10Mbps network. When extending 
your network, you should be aware of the configuration 
rules.

If you connect two Dual Speed Hub units directly 
together, the link between them operates at 
100Mbps.

Fast Ethernet (100Mbps) Configuration Rules

The Dual Speed Hub 8 and Dual Speed Hub 16 are Class II 
hubs. You can connect directly two Class II Fast Ethernet 
hubs (Class I Fast Ethernet hubs cannot be connected 
directly to other Fast Ethernet hubs). The total length of 
cable (A + B + C) between two workstations, or between a 
workstation and a non-repeater piece of equipment (such as 
a switch), must not exceed 205m (672ft). Each cable (A, B, 
or C) must not exceed 100m (328ft), as shown in Figure 3 
overleaf.
