Serial Console Port
The module can be configured by attaching the serial port to a DB-9 serial (RS-232)
equipped computer with terminal emulation software such as ProComm or Putty. The
Serial Console Port (DCE) is a mini DIN-6 female connector which can be changed
to a DB-9 connector with the included adapter. Attach the ends of a serial cable to
the serial port of the PC and the Serial Console Port of the module. The port is a
standard RS-232 asynchronous serial interface. The pin-outs are illustrated below.

Serial Connector Pin Outs
Some computers do not come with DB-9 serial port connectors and may require a
USB-to-serial port adapter.
The port is a standard RS-232 asynchronous serial interface. The serial ports is
configured for 57,600bps, 1 stop, 8 data, parity none.
RJ-45, SFP and Fixed-Fiber Ports
The RJ-45 Ethernet port supports 10BASE-T, 100BASE-TX and 1000BASE-T
protocols, auto-negotiation, auto MDI/MDI-X crossover and can be manually forced
to a specific speed and duplex mode.
The SFP interfaces support SERDES 100BASE-FX or 1000BASE-X fiber transceivers
and SGMII 10/100/1000BASE-T copper transceivers. The SFP interfaces operate
in manual mode or auto-negotiation and support full duplex operation.
NOTE: When using 100BASE-FX SGMII SFPs, the port must be manually
configured using the Command Line Interface (CLI). Interface settings can
be changed using the port command.
Fixed-fiber connectors are available with multimode (MM) dual fiber, single-mode
(SM) dual fiber and single-mode single-fiber (SF) options. They support ST and
SC connectors.
All ports can be enabled or disabled via network management. A port disabled with
Port Access Control Setup will still connect and allow 802.3ah Link OAM monitoring,
but blocks normal data traffic.
