Power Supply
Overview
Overview
The Axxius 800 Power Supply options operate from either 24 VDC or 48 VDC to
supply 5V power to the Axxius platform. A single Power Supply is capable of
powering the entire Axxius 800 unit. Equipping the Axxius with two Power Supplies
provides a simultaneously shared, redundant power feed to the unit. Front panel LEDs
provide easy-to-read power status and alarms. The Power Supply can remotely notify
network operations and monitoring centers of power faults through the Axxius SNMP
or NetworkValet EMS.
The 48 VDC power supply is available in two versions:
48 VDC I48 - the standard -48 VDC power supply.
48 VDC NI48 - provides non-isolated -48 volt to the backplane, to support the
FXO and OCU-DP Service cards.
