Important
Please review the electrical safety information in Chapter 7, Safety Precautions.
Connecting AC Power
To connect power, follow these steps:
1. Plug the end of the power cord into the power inlet socket on the E5.
Figure 3.2. E5 Power Inlet Socket
2. Plug the power adapter into a suitable AC power outlet. There is no On/Off switch and the
unit will begin to boot up as soon as power is applied.
3. The E5 will boot up and cOS Core will start. After a brief period of time, cOS Core will be
initialized and the E5 appliance is ready for configuration from a management workstation
using either the Web Interface or the Command Line Interface (CLI) as the management
interface.
Initial configuration is discussed in detail in Chapter 4, cOS Core Configuration.
Important: Protecting Against Power Surges
It is recommended that the purchase and use of a separate surge protection unit from a
third party is considered for the power connection to the E5 hardware. This is to ensure
that the E5 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.
