The console terminal shows the startup information of the router if the connection is
correct. For details, see the chapter “Starting and Configuring the Router”.
3.8 Connecting the Router to a LAN
I. Ethernet interface
The RPU provides two 100Base-TX FE interfaces. For their attributes, refer to the
section “RPU”.
The ERPU provides three 10/100/1000 Mbps auto-sensing Ethernet interfaces that
each accommodate an RJ-45 connector and an SFP module respectively for electrical
and optical connections.
The ERPU(H) provides three 10/100/1000 Mbps Ethernet interfaces, where two are
electrical and one provides both fiber-optic and electrical connectors.
When both electrical and optical connections are available, you can use only one at a
time. For the available SFP options and the interface attributes, refer back to the
section “ERPU“ in the chapter “Router Overview”.
II. Ethernet cable

Electrical Ethernet interface cable
Electrical Ethernet interfaces usually use category 5 twisted-pair cables, as shown in
the following figure.
Figure 3-9
Ethernet cable
Ethernet cables fit into the following two categories:
z
Straight-through cable, at both ends of which, wires are crimped in the RJ-45
connectors in the same sequence. The cable connects different types of devices,
such as a terminal device (PC for example) or router to a Hub or LAN switch. The
network cables shipped with the router are straight-through cables.
z
Crossover cable, at both ends of which, wires are crimped in the RJ-45 connectors
in different sequences. The cable connects the same type of devices, such as PC
to PC or PC to router. You can make crossover cables by yourself as needed.
