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 21.
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 named
ethernet0/0 through ethernet0/4 .
Figure 2 displays the location of the LEDs on each Ethernet port.

Table 3 describes the Ethernet port LEDs.

Console Port
The Console port is an RJ-45 serial port wired as DCE that can used for local
administration. An RJ-45 to DB-9 adapter is supplied.
See “Connectors” on page III for the RJ-45 connector pinouts.
AUX Port
The auxiliary (AUX) port is an RJ-45 serial port wired as a DTE that you can connect
to a modem to allow remote administration. We do not recommend using this port
for regular remote administration. The AUX port is typically assigned to be the
backup serial interface. The baud rate is adjustable from 9600 bps to 115200 bps
and requires hardware flow control.
