== Introduction ==

All Network Service Element&nbsp;come in two varieties: SPAN and TAP.&nbsp;&nbsp;

The SPAN model has two independent monitor interfaces.&nbsp; In a typical configuration, both ports will be&nbsp;connected to two SPAN output ports: one port duplicating all packets from the network to the site and the other port duplicating all packets in the opposite direction. This application&nbsp;offers great WAN visibility, including&nbsp;more precise traffic measurements than&nbsp;possible with flow based analysis or snmp.&nbsp; Other applications are possible, such as the monitoring of server traffic in a relatively small remote datacenter.

The fail-safe TAP model has been designed to be installed inline between the WAN Access Device and the local switch.&nbsp; No specific configuration of those devices is required.

&nbsp;

=== Physical location ===

Make sure the ventilation holes on the left and right side of the appliace do not become obstructed so air can flow freely trough the appliance.&nbsp;

&nbsp;

=== Network connections (appliance rear view) ===

This picture shows a MINIMAL SET&nbsp;of ports that must be connected.&nbsp; Connection to additional ports may be required in specific situations.

<u>All models:</u>

<span style="color:#FFFFFF;"><span style="background-color:#2B5680;">LAN1 & LAN2</span></span>: (redundant) MANagement ports: at least one of these ports must be connected to a local switchport.&nbsp;&nbsp;

<u>SPAN model:</u>

<span style="color:#FFFFFF;"><span style="background-color:#3A3589;">LAN3</span></span>: MONitor port: this port must be connected to the SPAN representing the traffic FROM the network*.

<span style="color:#FFFFFF;"><span style="background-color:#258463;">LAN4</span></span>: MONitor port: this port must be connected to the SPAN representing the traffic TO the network*.

<u>TAP model (inline):</u>

Install the appliance between the WAN Access Device and the local switch.&nbsp; Connect <span style="color:#FFFFFF;"><span style="background-color:#3A3589;">LAN3</span></span> to the WAN access device and <span style="color:#FFFFFF;"><span style="background-color:#258463;">LAN4</span></span> to the local switch.&nbsp; The applicance does not provide PoE.
