Getting Started with Your Fiber Guardian

Connecting the Power and the Network Cables
Connecting the Power and the Network
Cables
Before starting to work with your unit, you must connect the power. You
may also wish to connect the LAN/WAN network cable, especially if you
intend to install your unit in a rack. You can also connect a network cable
for local access to the unit (front port).
The Fiber Guardian is available with either AC or DC power supplies. The
unit has redundant AC or redundant DC power modules. To benefit from
this redundancy, be sure to connect both power supplies, each to a
separate circuit.
As soon as you connect the unit to a power source, the Baseboard
Management Controller (BMC) starts its initialization. During this
operation, the LEDs on the front panel will be lit in the following
sequence:

All LEDs will turn to yellow for about 40 seconds.

All the LEDs will turn off for about 5 seconds.

Finally, the power LED ( ) will turn to blinking green, indicating
that the BMC is now ready (unit is in standby).
Note: Your unit has been designed to restart automatically when the power
comes back after a power outage. However, in this case, the initialization
sequence will differ from the usual initialization sequence explained above.
For detailed information about the LEDs, see LED Indicators Description on
page 286.
