Installing the ISDN LAN Modem
29
CAUTION:
You should only have one computer physically connected to the ISDN
LAN Modem during configuration. Once you complete the configuration process,
connect any other computers you would like to have on the LAN and then power
cycle each computer. If the newly-added computers cannot communicate with the
ISDN LAN Modem, refer to “Evaluating Symptoms and Solutions”
in
Chapter 9
.
Connecting to Another
Ethernet Hub
You can connect to another Ethernet hub to allow up to 25 users to access the
WAN. Instructions for adding another Ethernet hub to allow 10 users, a more
common scenario, is as follows.
Before You Begin
In addition to an external 10BASE-T Ethernet hub, you will need a 10BASE-T
Ethernet cable, which may have been provided with the additional hub. If the hub
to which you are connecting your LAN Modem does not have an MDI/X switch,
you must use a crossover cable.
1
Insert one end of the 10BASE-T Ethernet cable into one of the four LAN ports on
the back of the ISDN LAN Modem, as shown in Figure 15.

10BASE-T Hub-to-Hub Connection
2
Insert the opposite end of the cable into a 10 BASE-T Ethernet port on the other
Ethernet hub.
If you are connecting to an OfficeConnect Hub 8/TPO, insert the opposite end of
the Ethernet cable into port 8 and then set the MDI/X switch to MDI (that is,
pressed in). Make sure that the LED associated with that Ethernet port is lit. If it is
not, try changing the MDI/X switch setting.
