3.2 Control and Monitoring Software
The Digivance CXD EMS or customer supplied NMS using the Digivance CXD SNMP Agent
is used to provision and configure the system for operation. This includes initializing the
system, setting up the Hub and RAN element identification schemes, tenant processing, setting
alarm thresholds, and setting forward and reverse path RF gain adjustments. The EMS or NMS
software is also used to get alarm messages (individual or summary), data measurements, or to
upgrade the Hub/RAN system software. All control and monitor functions can be effected
using either the EMS or through a NMS.
3.3 Fault Detection and Alarm Reporting
LED indicators are provided on each of the respective modules populating the Hub Digital
Chassis, RF Chassis and RAN Chassis to indicate if the system is normal or if a fault is
detected. In addition, a dry contact alarm interface can be provided as an accessory item that is
managed by the EMS software with normally open and normally closed alarm contacts for
connection to a customer-provided external alarm system. All Hub and RAN alarms can be
accessed through the SNMP manager or the EMS software GUI.
3.4 Powering
The Hub Digital and RF Chassis are powered by ±48 Vdc and must be hard-wired to a local
office battery power source through a fuse panel.
The RAN is powered by 120 or 240 Vac (50 or 60 Hz) and must be hard-wired to the AC
power source through a breaker box. The RAN is pre-wired for 120 VAC operation but can
be converted to 240 VAC operation if required. On an optional basis, a back-up battery kit is
available for the RAN. The battery-backup system powers the RAN if the AC power source is
disconnected or fails.
3.4.1 HUB Power On/Off
Hub Power On
• Power to the Hub rack is enabled using the power system supplied by the customer
located in the Hub shelter. Power to the Hub must be supplied through a fuse panel
such as the 20 position ADC PowerWorx power distribution panel (available
separately). The power circuit for each active element of the system must be protected
with a 3 Amp GMT fuse.
Hub CompactPCI Chassis Power On
• Identify the power supply module for the chassis to be powered on
• Insert the power supply module(s) in the chassis
