Installing appliances on a network rack

For instructions on how to unpack and install an appliance in the network rack, see the Dell Rack Installation Guide. If the box is damaged or any parts are missing, contact Dell Support.

Connecting appliances to the network

After the appliances are installed in their server rack, you need to connect each appliance to the network and to a power supply. For each appliance, you need two network cables (gigabit) plus additional network cables for each monitoring port that you want to connect.

When you connect the appliances’ control ports to the private switch, the Management Server, Sniffers, and Archivers can communicate with each other across your network. You can also access the Foglight browser interface. When you connect the appliances’ DRAC ports, you can use the DRAC utilities to manage and troubleshoot the appliance. Finally, when you connect a Sniffer’s monitoring ports, Foglight has the ability to capture live web traffic crossing the Sniffer’s tap points.

To connect an appliance to the network:

1

Connect the appliance’s Control Port (eth0) to the network switch.

2

Connect the appliance’s DRAC Port to the network switch. If you need additional instructions, see the Dell Remote Access Controller documentation included with the appliance.

Figure 6. Connecting appliances to the network

3

Connect the power cable to the appliance’s Power Supply and then to your local power supply. Do NOT power on the appliance at this time.

4

Repeat this procedure to connect all the other appliances in your installation.

Connecting Sniffers

You connect the Sniffers to all external Archivers (to enable the capture subnet) and to network taps (to enable monitoring).

For more information, see the following topics:

Connecting Sniffers to network taps

To install a network tap between two points on a network, you replace the network cable connecting these points with a pair of cables, both feeding into the tap. Then you connect the tap’s monitoring ports to available Monitoring NICs on a Foglight APM appliance that contains a Sniffer. The tap passes through all traffic between the two points normally so there is no disruption to the normal traffic flow, and it copies that traffic to its monitoring ports. For physical appliances with six monitoring ports, a Sniffer can be connected to up to three network taps. For information about where to install network taps, see Network taps.


	NOTE: One of the installation scenarios for virtual appliances also uses a network tap. Connect the virtual Sniffer’s Monitoring Network A and Monitoring Network B NICs to the monitoring ports on the network tap. A virtual Sniffer can monitor one network tap only, but you can connect as many Sniffers to the tap as the tap supports. For more information about monitoring a virtual network through a network tap, see Monitoring multiple hosts through a centralized Sniffer.

To connect a network tap to a Sniffer:

1

Install a network tap in the desired location in the network.

2

Connect the monitoring ports on the network tap to two monitoring ports on a Sniffer’s appliance.
