The following ports are located on the backside of the 675e.

A.1.1 LAN Interface

The LAN interface uses an Ethernet port that conforms to the IEEE 802.3 and 802.3u protocols and supports 10 or 100MBps half-duplex data rates on category 3 (10MBps) or category 5 (00MBps) twisted-pair wire at a distance of up to 100 meters or less. The Ethernet connector is an RJ-45. The following table shows the connector pinouts.
