Use the rubber feet for desktop use. The four self-adhesive rubber feet prevent your Dual 56K LAN Modem from
sliding. Attach the feet to the underside of the LAN Modem in the marked corners.
Use the Stacking Clip to stack two or more OfficeConnect units together securely.
CAUTION: You can stack up to a maximum of four units. Smaller units must be stacked on top of larger units.
To stack two units:
1 Place the first unit on a flat surface.
2 Fit the clip across the top of the unit, as shown.
The longer end of the fastening pieces should point
downward.
3 Align the fastening pieces over the slots on each side
of the unit, and then push the clip down gently to
secure it. Ensure that the fastening pieces snap into
the slots.
4 Rest the second unit on top of the clip, and align it
with the front of the bottom unit.
5 Press down gently to secure the top unit onto the clip,
ensuring that the fastening pieces fit into the slots,
as shown.
To unstack units, gently pry the top unit away from the clip, and
then carefully pull each fastening piece out of its slot to detach
the clip from the bottom unit.

After you have finished configuring your Dual 56K LAN Modem, you can connect an additional Ethernet hub or hubs to
the Dual 56K LAN Modem to add up to 25 users. An example of a ten-user connection is shown.
To connect an additional hub:
1 Insert one end of a 10BASE-T Ethernet cable
(not included) into any available port on the back
of the Dual 56K LAN Modem.
2 Insert the opposite end of the cable into one of
the 10BASE-T Ethernet ports on the Ethernet
hub. (If you are connecting to an OfficeConnect
Ethernet Hub 8, insert the cable into port 8.)
3 If you are connecting to an OfficeConnect
Ethernet Hub 8, set the MDI/MDIX switch to
MDI (that is, pressed in).
4 Connect additional workstations to any
available port.
If the hub to which you are connecting does not
have an MDI/MDIX switch, you will need a
cross-over Ethernet cable.
