ACCESS NODE AND METHOD

摘要

An all-encompassing fully integrated communication Access Node for call stations and other security and communications equipment includes a modular housing within which is mounted wire and wireless communication systems and power systems. The housing has a chassis for mounting the electronics and battery modules and a backbox and panel for staged installations, managing cables and providing heat dissipation. A door to the chassis is secured using latch hooks with roller bearings. Optical cable termination is provided as a two sided patch panel. Dual power supplies provide power to internal components and to external components via a distribution module. Backup power is provided by a custom battery backup with a charging controller. Cooling is controlled by dual fans and a fan controller moving air through the housing using openings and baffles. Freestanding pedestal mounting of the Access Node and various other mounts for column, wall, or ceiling to any substrate or condition is an option. Venting through a plug prevents pressure build up.

主权项

1. An Access Node for a communication system, comprising:
a column shaped housing having a chassis, a rear panel and a door; a network switch or application server mounted to the chassis within the column shaped housing, the network switch being operable to communicate with remotely located call stations; a power module mounted to the chassis within the column shaped housing, the power module being connected to external power and being operable to provide power to the network switch; a battery back-up power supply mounted to the chassis within the column, the battery back-up power supply being operable to provide power to the network switch in the event of failure of the external power; a fan controller and a fan mounted to the chassis within the column, the fan controller being operable to drive the fan; the chassis and rear panel and door forming a closed interior space and defining air flow channels within the closed interior space, a first air flow channel extending over the network switch and the power module and a second air flow channel extending along the rear panel, the first and second air flow channels being substantially parallel with one another; and the fan being driven to move air in a circulating air flow within the closed interior space such that air flow driven by the fan causes air circulation in a first direction over the network switch and the power module and in a second direction along the rear panel so that heat in the circulating air may dissipate at the rear panel.
