Operation
4.1 Operating Procedure
After completion of System Installation Procedures (Chapter 3), the AC
power mains plug should be inserted in the RADring and then to a socket
outlet provided with a protective earth contact.
The protective action must not be negated by use of an extension (power
cable) without a protective conductor (grounding).
Note
Grounding - The RADring should always be grounded through the protective
earth lead of the power cables.
Initialization
1. RADring Enclosure: Connect the mains and/or the optional redundant
power cables to the corresponding RADring power supply module
receptacles.
2. Once the power cables are connected, the Power switch(s) on the
back panel of the RADring must be turned on; they must light as well
as all of the green power (PWR) LEDs of the modules.
PS1 only: PS2 only: With redundant power supply:
PS1 set to ON PS1 set to OFF PS1 set to ON
PS2 set to OFF PS2 set to ON PS2 set to ON3.
Note
Before plugging the unit into an electrical outlet, the user must ensure that the
power supply switch PS1 and/or PS2, are set on the CML or CML/NM module
according to the desired usage.
3. The user must verify that the ON LEDs on the CML or CML/NM card
are functioning properly. In the event that there is any type of failure,
however, the FLT LED will light, indicating that there is a failure in the
corresponding power supply.
Operation
The RADring operates entirely unattended. Operator intervention is only
required when a cable fault condition exists, or when the DC power supply
has failed.
The RADring can be monitored and controlled from the RADview
management station. For instructions regarding installation and operation of
the RADview management, refer to Part 2. Alternatively the RADring status
can be monitored from the front panel.
