Network Cabling Specifications
The following sections describe the cables needed to install your Cisco IR8340 router:
Console Port Connection
The Cisco IR8340 router includes an EIA/TIA-232 asynchronous (RJ-45) console port. The console port
provides access to the router locally using a console terminal connected to the console port. This section
discusses important cabling information to consider before connecting the router to a console terminal.
Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the
cable. Only one port can be used at the same time.
The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. The console
port does not support hardware flow control.
Preparing for Network Connections
When setting up your router, consider distance limitations and potential electromagnetic interference (EMI)
as defined by the applicable local and international regulations.
Network connection considerations are provided for several types of network interfaces and are described in
the following sections:
Warning
Ethernet Connections
The IEEE has established Ethernet as standard IEEE 802.3. The Cisco IR8340 router supports 10/100/1000
STP Ethernet connection and 100/1000 SFP connection.
Serial Connections
Serial connections are provided by the RS232 serial Network Interface Module (NIM) . Before you connect
a device to a serial port, you need to know the following:
• Type of device, data terminal equipment (DTE) or data communications equipment (DCE), you are
• Type of connector, male or female, required to connect to the device
• Signaling standard required by the device

Two types of power supplies are supported on the Cisco IR8340: a low-voltage DC power supply and a
high-voltage DC/AC power supply. Take caution when selecting the correct input voltage for the power supply
installed or damage will result.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network
voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some
LAN and WAN ports both use RJ-45 connectors. Statement 1021
