High Availability Powering
High availability powering can be achieved in several ways.
Redundant AC/DC rectifiers, using at least one more rectifiers than needed to have extra resources when any of the rectifiers is failing.
Battery backup, battery backup is supported. Note that the PCC controller and cable kit is needed when using batteries.
These types of redundancies can also be combined to achieved even higher power availability.
Rectifier redundancy
Using at least one more rectifier than the power requirement will give rectifier redundancy. This should normally be combined with the PCC so attention can be distributed when a rectifier fails.
A more than one power system is required if the maximum power consumption is more than 800W.
Battery Backup
The battery backup system can be connected to the AC/DC power system to provide Uninterrupted Power Supply (UPS) if the mains fails.
Batteries can be ordered with two capacities, 31 Ah or 62 Ah. The choice depends on the total power load and the required backup time.
The MX-ONE Classic consumes typically 250W depending on configuration, see MX-ONE Classic, BFD76140/1 on page 51.
Example: A 62 Ah battery can provide:
-> 62Ah / (250W / 48V)A = 12 hours of backup time.
This is only a rough calculation and the accurate power planning must be done considering total power consumption of all the equipment in the system that the battery must supply the power to. The battery backup system must be able to supply uninterrupted power during mains failure up to the maximum required backup time.
For details of the power installation, see installation instructions for INSTALLING MIVOICE MX-ONE HARDWARE and the Suppliers manual for the power systems.
