The base cabinet includes VCU, CPU, floppy-disk drive, fans, and PSU. All voice/system disk
drives require the same amount of power, regardless of their storage capacity.
The following example for an Octel Overture 300 message server shows the calculation of the input
power requirements for an 8-port message server, equipped with two 4-port line cards, one integration
card, and two voice/system disk drives:
Base cabinet 150 W
Two 4-port line cards 20 W
One integration card 10 W
Two voice/system disk drives 50 W
Total input power 230 W
Total volt-ampere rating (1.5 x 230) 345 VA
Round the total-input power value and the total volt-ampere rating up to the next multiple of 50,
producing the values to be used to select a suitable power source:
Total continuous input power requirement is 250 watts and 350 VA
Isolation Transformer
For installation sites that could experience power-line transients from lightning or power switching, the
use of an isolation transformer is recommended. A dedicated isolation transformer must be rated at the
following:
- 750 VA or greater is required for the Octel Overture 200.
- 1 kVA or greater is required for the Octel Overture 300.
Contact Octel for isolation transformers that have been tested and qualified for use with Octel Overture
200/300.
