Understanding craft Ethernet connection to the node
IP-RN 8000 Installation & Commissioning Guide 133
When configuring the node from the active BIO/SC module, all configurations apply to the entire node.
However, there are some cases where you need to plug the serial cable into the serial port on the inactive
BIO/SC module. For example, if the node uses Ethernet backhauls, the only way to loopback test the
Ethernet link associated with the inactive module is to plug the serial cable into the serial port on the inactive
BIO/SC module.
CLI/telnet/craft Ethernet
CLI/telnet/craft Ethernet is made by connecting an Ethernet adapter on your laptop to the Ethernet craft port
on the BIO/SC module, either directly using a cross over cable or through a switch or hub using straight
through cables. You must configure appropriate IP addresses and masks on the BIO/SC Ethernet port (using
CLI/serial) and on the laptop Ethernet port. Then you launch telnet and open a CLI session with the node
using the node IP address or the craft Ethernet IP address.
Because you can open multiple CLI sessions at a time using telnet, this method is required during certain
phases of the commissioning procedure.
CLI/telnet/backhaul
CLI/telnet/backhaul is made through the existing backhaul network. This assumes a normally operating
network with backhaul links that are up and running and IP addressing that is fully configured and correct.
You can open a telnet session with the node’s node IP address from any location support by the IP network
design.
Understanding craft Ethernet connection to the node
The BIO/SC module has two craft ports:
• Female DB-9 for serial connections
• RJ-45 Ethernet
For information about BIO/SC craft ports, see Understanding the Base Input Output/System Controller
module on page 22. There are two ways to connect a laptop Ethernet to the BIO/SC craft Ethernet (see
Figure 21
):
• Directly using a cross-over cable
• Indirectly using an Ethernet switch and two straight-through cables
