Mains Electricity Power Supply

Some equipment is designed to be connected to non-industrial (domestic) socket outlets, while other equipment is designed to be permanently connected to the supply or connected by industrial socket outlets.

The site must meet the following power requirements:

• A mains electricity supply with a voltage between 205 V and 240 V must be avail­able in the site.
• For every ordered AC/DC power supply unit in the MX-ONE, there must be one connection to the mains power supply. This connection can either be a permanent connection or a socket outlet for an industrial plug. Industrial socket outlets must comply with IEC 60309 or with a comparable national standard.
• Every Media Gateway and every server requires its own socket outlet.
• An adequate amount of non-industrial (domestic) grounded socket outlets must be available and easily accessible at the site. The socket outlets should be located near the exchange equipment they are intended to serve.
• An adequate amount of socket outlets should be available for additional equipment. See Additional Equipment for more details.
• A few reserve socket outlets must be left for occasional working purposes, like installation, maintenance, testing, cleaning, and so on. It is recommended to leave at least five socket outlets, regardless of the size of the exchange.
• For service purposes, there must be an accessible main switch (disconnect device) in the site, for disconnection of permanently connected equipment from the mains supply.

A power emergency switch is not mandatory.
