2.6
Connecting Supply Power
This section includes details on the NetClock’s AC and/or DC power systems (
Note
: The
DC power option is available with
NetClock 9483
only).
Depending on the equipment configuration at time of purchase, NetClock can be powered
from:
an AC input
a DC input
with both AC, and DC input (DC input is an option for NetClock 9483 units only).
Supplying both AC and DC input power provides redundant and automatic power switchover
in case one or the other input power sources is lost.
Before connecting power to the unit, be sure that you have read all safety information detailed
in section "SAFETY" on page 31.
2.6.1
Power Source Selection
Note:
Applies to NetClock 9483 only.
If both an AC, and a DC power source are connected to the unit, the following rules apply:
If AC and DC power are both applied, AC power is used.
If DC power is applied, but AC power is not, then DC power will be used.
If AC and DC power are both present, but AC power is subsequently lost, NetClock will
automatically switch to using the DC power input.
DANGER!
— This unit will contain more than one power source if both the AC
and DC power options are present. Turning off the rear panel power switch will
NOT remove all power sources.
The following sections discuss AC and DC power input. Connect AC and/or DC power, as
required.
