This section is an overview of the NetWall E10 product's external connectivity options.

Figure 1.2. NetWall E10 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 E10 that has the Ethernet ports and the term "Back" to the side that has the status lights.

The NetWall E10 features a number of connection ports on the front panel:

4 x RJ45 Gigabit Ethernet interfaces

These have the logical cOS Core interface names WAN, LAN, G1 and G2. These names are written above each interface on the E10 casing.

The LAN interface is used for initial management connection. The WAN is usually used for connection to the public Internet but any other available interface could be used for this purpose.

In the default cOS Core configuration, the LAN interface of the E10 has a IPv4 DHCP server enabled on it so it will automatically hand out IPv4 addresses belonging to the default management network to a connecting client. In addition, the WAN interface is enabled as an IPv4 DHCP client so that it can be automatically be assigned its IPv4 addresses when it is connected to the gateway of an Internet Service Provider (ISP).

The default cOS Core configuration also contains a predefined IP rule set that allows clients on the LAN interface to access the Internet with a web browser through the WAN interface.
An RJ45 RS-232 console port

This port 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.

	Note: The two USB Type A ports are not currently used
	The two USB Type A ports on the E10 front panel are for future functionality and are not currently used by cOS Core.

All the Ethernet interface ports function independently of each other and are not connected by a switch fabric. All are capable of link speed auto-negotiation and can operate using 10Base-T, 100Base-Tx, or 1000Base-T. The interface names are written by each interface.

The full connection capabilities of all the NetWall E10 Ethernet interfaces are listed at the end of Appendix A, NetWall E10 Specifications.

RJ45 Ethernet Interface Status LEDs

The status lights on the sides of the NetWall E10 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.

Note the NetWall E10 also has status lights on the opposite side from the interface ports and these are described next in Section 1.3, Status Lights.

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