Addresses and Port Numbers
Hardware Address
The hardware address is also referred to as the Ethernet address, physical address, or MAC
address. The first three bytes of the Ethernet address are fixed and identify the unit as a Lantronix
product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit.
Sample ways hardware address may be represented:
 00-80-A3-14-1B-18
 00:80:A3:14:1B:18
IP Address
Every device connected to an IP network must have a unique IPv4 address. This address
references the specific unit.
Port Numbers
Every TCP connection and every UDP datagram is defined by a destination and source IP
address, and a destination and source port number. For example, a Telnet server commonly uses
TCP port number 23.
The following is a list of the default server port numbers running on the SGX 5150:
 TCP Port 22: SSH Server (Command Mode configuration)
 TCP Port 23: Telnet Server (Command Mode configuration)
 TCP Port 80: HTTP (Web Manager Configuration)
 TCP Port 21: FTP
 TCP Port 443: HTTPS
 UDP Port 30718: Lantronix Discovery Protocol
Product Information Label
The product information label on the device contains the following information about the specific
unit:
 Model Name
 Product Part Number
 Barcode
 Product Revision
 Country of Manufacturing Origin
 Serial Number
