2.5. Connecting Power

Home Prev	NetShield 300 Series Getting Started Guide	Next

This section describes connecting power. As soon as power is applied, the NetShield 300 Series will boot-up and cOS Stream will start.

	Important: Review the safety information
	Before connecting power, please review the electrical safety information found in Chapter 6, Safety Precautions.

Connecting AC Power

To connect power, follow these steps:

Connect the end of the power adapter's power cord to the power inlet on the NetShield 300 Series. The 300 Series has a threaded connector which must be screwed firmly in place to prevent the power cable accidentally detaching.

Figure 2.4. NetShield 300 Series Power Supply Connection

Plug the power adapter into a suitable AC power outlet.

There is no On/Off switch. The 300 Series will boot up as soon as power is applied and cOS Stream will start. The progress of the process can be seen on a CLI console connected to the local console port.

After a brief period of time, cOS Stream will be fully initialized and the NetShield 300 Series is then ready for configuration using a direct console connection or via a network connection to the default management Ethernet interface.

Initial cOS Stream configuration is described in Chapter 3, cOS Stream Configuration..

The Recessed Reset and Restart Buttons

Located to the left of the power connector are two recessed buttons that can be pushed in with a suitable pointed tool. An opened paper-clip could be used for this.

Figure 2.5. The 300 Series Restart Button (below the reset button)

The top button (solid inverted triangle) is for resetting to factory defaults and its usage is discussed in Chapter 4, Resetting to Factory Defaults. The lower button (circular arrow) will immediately restart the 300 Series unit if it is pushed in momentarily but will not alter the current cOS Stream configuration. Note that all current traffic connections will be lost following a restart.

	Important: Consider power surge protection
It is recommended to consider the purchase and use of a separate surge protection unit from a third party for the power connection to the NetShield 300 Series hardware. This is to ensure that the appliance is protected from damage by sudden external electrical power surges through the power cable. Surge protection is particularly important in locations where there is a heightened risk of lightning strikes and/or power grid spikes. Any surge protection unit should be installed exactly according to the manufacturer's instructions since correct installation of such units is vital for them to be effective.
