4.2. Access Ports and Connectors
There are two RJ port connectors built into the EM316LNXNM front panel for serial and Ethernet access.
The RS-232 port connects to a PC serial port for direct "out-of-band" secure access to the command line
interface (CLI). The serial interface configuration is discussed later in this section. The Ethernet port
opposite the serial port connects to an IP network for CLI and SNMP control.
The EM316LNXNM-OT includes two SFP sockets in addition to the two RJ ports. An SFP transceiver
may be installed in each of these sockets for addition network connections. Refer to the transceiver
documentation for connection information not covered in this document or appendices.
