Virtual Services Platform 9010 chassis
An n + 1 redundant configuration provides power in the event of a single power supply failure, single
circuit breaker trip, or knocked-out power cord.
An n + n redundant configuration provides power in the event of a loss of a single power phase in
the building. Balance the line side voltage source between building phases.
Use n + n redundancy to ensure redundancy in the event that an external failure occurs, for
example, an entire power feed within the building fails. To ensure n + n redundancy, you must install
power supplies to provide twice the power requirements of your hardware configuration.
Important:
The system reserves the following power requirements:
• 80 Watts (W) each for the primary and secondary Control Processor (CP) modules
• 70 W each for the Switch Fabric (SF) modules located in slots 1 and 4
• 1,900 W for a pair of 9010CM cooling modules that operate at full speed
Power feed redundancy
Avaya recommends that you use two separate power feeds for the power supplies.
The power supplies in the Virtual Services Platform 9010 chassis are divided in two shelves. Each
shelf consists of four independent power source and filter circuits. The eight circuits are independent
and you can configure either building phase to any circuit.
If you use n + n redundancy and plug four power supplies in to power feed "A", and the remaining
four power supplies in to power feed "B", this configuration gives you power feed redundancy.
Ensure that each AC power circuit connects to a dedicated breaker.
Cooling modules
The Virtual Services Platform 9010 uses two cooling modules. Install the two cooling modules at the
front of the chassis, below the CP and I/O modules. Each cooling module includes four fans.
Virtual Services Platform 9010 uses two cooling modules to create airflow redundancy. In the case
of a single fan failure, or full failure of a cooling module, the other cooling module fans blow cooling
air through the failing fans to continue cooling installed modules.
Warning:
If the upper cooling module fails, leave it in place until you can install a replacement cooling
module. Do not remove the top cooling module and leave that slot empty. The chassis will
depressurize with a significant loss in cooling capacity of the fans. Damage to equipment can
result.
Do not partially remove the fans and leave them in the chassis. This action results in the
blockage of airflow, causing significant loss in the cooling module air volume.
You must either fully seat a cooling module and lock it into the slot, or completely remove it from
the chassis slot.
