Power On the DC Power Entry Module
The power-on procedure is the same for both the DC PEM modules (UBR10-PWR-DC= and
UBR10-PWR-DC-PLUS=).
To power on the DC PEM module:
Verify if the DC power cables are connected, see
Step 1
uBR10012 Router" section on page
if the safety covers are installed on the DC terminal blocks on the PEMs.
Verify that DC PEM power switch on each PEM is in Standby(0) position.
Step 2
Remove the tape from the circuit breaker switch handle.
Step 3
Power on the power source that is suppling the DC power to the chassis.
Step 4
If you are using the external AC-input power shelf, this step requires plugging in multiple AC power
Note
cords into the back of the unit and into the outlets providing the AC power source.
The internal fans on the UBR10-PWR-DC-PLUS= PEM module start running and are audible as soon
Note
as the DC-input power cables are connected to the facility power source and the facility power is turned
on, although the DC power enable switch is in Standby (0) position.
Step 5 After powering on the DC power source, verify the LEDs on the DC PEMs.
If the FAULT LED on the PEMs do not illuminate (yellow), see the
page
Tip The label on the chassis indicates the actual provided voltage range.
Step 6 Turn the power switch on each DC PEM to the ON (|) position.
