This section is an overview of the NetWall 300 Series product's external connectivity options.

Figure 1.2. NetWall 300 Series Interfaces and Ports

	Note: The meaning of the terms "Front" and "Back"
	The term "Front" will be used in this guide to refer to the side of the 300 Series that has the Ethernet ports and the term "Back" to the side that has the status lights.

The NetWall 300 Series features the following connection ports:

6 x RJ45 Gigabit Ethernet interfaces

These have the logical cOS Core interface names G1 to G6. These names are written above each interface on the NetWall 300 Series casing.

The G1 interface is used for initial management connection over a network. The G6 interface is normally used for the initial connection to the public Internet.
2 x Gigabit SFP interfaces

These have logical names S1 and S2.

Note that only the SFP modules available from Clavister have been tested to function correctly with the 300 Series hardware. Clavister cannot guarantee that others will function correctly.
An RJ45 RS-232 console port

This port (marked |O|O|) is used for direct access to the cOS Core Boot Menu and the cOS Core Command Line Interface (CLI). Connecting to this port is described in Section 3.4, Local Console Port Connection.

In the predefined default cOS Core configuration, the G1 interface of the NetWall 300 Series has an IPv4 DHCP server enabled so it will automatically hand out IP addresses belonging to the default management network to a connecting client. In addition, both the G6 and S1 interfaces have an IPv4 DHCP client enabled so that they can automatically be assigned an IP address if either or both are connected to an ISP (dual connection can provide redundancy).

The default cOS Core configuration contains a predefined IP rule set that allows clients on the G1 interface to automatically access the Internet via either G6 or S1. If both interfaces provide Internet access, S1 will take precedence because its predefined all-nets route has a lower metric value.

The default cOS Core configuration is discussed further in Section 4.1, The NetWall 300 Series Default Configuration.

Note that the G6 interface must have a connection to the Internet if the unit is to be automatically managed on initial startup by InControl using the Zero Touch feature. This is discussed further in Section 1.3, Zero Touch Support.

	Note: The two USB Type A ports are not currently used
	The two USB Type A ports on the 300 Series front panel are for future functionality and are not currently used by cOS Core.

The full connection capabilities of all the NetWall 300 Series Ethernet interfaces are listed at the end of Appendix A, NetWall 300 Series Specifications.

RJ45 Ethernet Interface Status LEDs

The status lights on the NetWall 300 Series RJ45 Ethernet interface sockets indicate the following states for each interface:

Left LED:
1. Solid Green - The interface has power.
2. Flashing Green - The interface is active.
Right LED:
1. Dark - 10 Mbit link or no link.
2. Green - 100 Mbit link.
3. Yellow - 1000 Mbit link.

System Status Indicator LEDs

The two status LEDs on the 300 Series indicate the following:

Power - This shows power is supplied to the unit.
Status - This shows that cOS Core is running.
