The following illustration shows the connectors located on the rear panel of the Cisco 675 units.
The following ports are located on the backside of the Cisco 675.
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.
| Pin | Signal |
|---|---|
1 | TXD+ |
2 | TXD- |
3 | RXD+ |
6 | RXD- |
The management port uses an RJ-45 connector.
The connector pinouts for the management port are shown in the following table.
| Pin | Signal |
