Rack Alarm Module (ALM) is a plug-in alarm unit, which will be<br />
used if Rack alarms are requested. The module is to be used in<br />
conjunction with the RPSA to provide the rack alarm interface for<br />
up to five NDM subracks that have NDA as input unit. To convey<br />
the rack alarms to the ALM unit of the RPSA, a standard RJ45<br />
cable is used (not supplied by <strong>Nokia</strong>).<br />
NDM DC Unit (NDU) is a DC/DC Power plug-in unit for NDM<br />
Subracks. NDU is a subrack specific interface point for battery<br />
voltages and rack alarms when a single subrack is fed with<br />
a nominal battery voltage of 24/48/60 V (range -20 - 75 VDC).<br />
NDM AC/DC Unit (NAU) is an AC/DC Power plug-in unit for NDM<br />
Subracks. NAU is a subrack specific interface point for AC mains<br />
voltage and rack alarms when a single subrack is fed with<br />
a nominal mains voltage of 115/230 VAC (range 90...264 VAC).<br />
Rack specific DC power supply adapter (with 6 outputs and<br />
two 6mm 2 battery inputs) is designed primarily for ACM2/<br />
ACM4 systems. The unit is 1U high and it is suitable for 19 in.<br />
installation. Separate brackets (TX21090.65) are needed for ETSI<br />
installation. Total battery power is 600 W (15 A) and criterion<br />
power > 1000 W (subrack specific fuses).<br />
