Connecting expansion modules
Installation planning is required for base stations.
Before connecting any Station Modules required for base stations, please see Configuring
expansion modules on page 8 for more
information on the installation rules involved.
In order to keep the default port and extension numbering, connect Trunk Modules to the Expansion Cartridge beginning at the top and working down; connect Station Modules to the Expansion Cartridge beginning at the bottom and working up.
Installing Remote Power Interconnect (RPI) units
The RPI unit should have the DC backup power supplied by a UL listed UPS.
The UPS should have an output voltage rating of 44 to 50 V DC, with a maximum fault current limit of 6 A to protect the RPI output wiring. Otherwise, it may be necessary to use class 1 wiring.
The RPI units must always be installed inside a building.
The AC outlet powering the RPI should be installed near the equipment and should be easily accessible.
The length of the RPI cord, from the outside surface of the unit to the plug, should be a minimum of 1.3 m (4 1/ 2 ft.) and a maximum of 4.6 m (15 ft.).
