Asynchronous port
The asynchronous serial port (ASYN0) is wired as a DTE (Table 9 on page 50),
and can be used as general purpose port for terminals, printers or modems.
The default communications settings are:
• 9600 bps
• 8 data bits
•1 stop bit
•no parity
• hardware flow control
Ethernet SFP sockets
The router has two eth interfaces (labelled Ethernet): eth0 (labelled 0) and eth1
(labelled 1). Each Eth interface has two connectors — an RJ-45 connector for a
10/100/1000 Mbps copper connection, and an SFP socket for a fibre-optic SFP.
Only one of these can be operational at once. When an SFP transceiver is
installed, the corresponding 10/100/1000 Eth port is disabled. When the SFP is
removed, the RJ-45 port is again operational.

Warning Do not look into SFP cables or transceivers. Disconnected
fibres or connectors may emit invisible laser radiation, which can
damage eyes.
The Ethernet SFPs sockets support the following Small Form-factor Pluggable
transceivers:
• AT-SPSX (previously AT-MG8SX)
• AT-SPLX10 (previously AT-MG8LX10)
• AT-SPZX80 (previously AT-MGZX)
For more information about SFP transceivers, see “SFP Ports (AR770S only)”
on page 46.
