Ethernet Ports
Five 10/100 Ethernet ports provide LAN connections to hubs, switches, local servers,
and workstations. You can also designate an Ethernet port for management traffic.
The ports are labeled 0/0 through 0/4. For the default zone bindings for each
Ethernet port, see "Default Device Settings" on page 31.
When configuring one of the ports, reference the interface name that corresponds
to the location of the port. From left to right on the front panel, the interface names
for the ports are ethernet0/0 through ethernet0/4.
Figure 4 displays the location of the LEDs on each Ethernet port.

Console Port
The Console port is an RJ-45 serial port wired as data circuit-terminating equipment
(DCE) that can be used for local administration. Use a straight-through cable when
using a terminal connection and a crossover cable when connecting to another DCE
device. An RJ-45 to DB-9 adapter is supplied.
See "Connectors" on page 60 for the RJ-45 connector pinouts.
