1.0 Introduction
Reliable power and power status at Aurora VHub installations are essential to ensure the operation of this critical
segment of the network. The VHub architecture supports an all optical input and output, with no nearby physical
connection point for a DOCSIS transponder.
The solution is to monitor the power supply through an optical connection. The Optical Status Monitor (OSM1)
consists of an Alpha Optical Interface (AOI) unit and a Status Interface & Power (SIP) card with the Comm Kit
to attach to the XM2-300HP power supply. The OSM1 connects the Alpha power supply into an existing VHub
architecture. Power supply data is transported to the head-end via existing ber where an Aurora controller
module displays the power supply status in Aurora’s OptiTrace software and converts the data to a standard
SNMP format. The power supply data can then be accessed from the operators’ existing power supply monitoring
software.

1.0 Introduction
1.1 OSM1 Connections
Within the Aurora optical management system, the OSM1 and subsequent power supply is
treated as a sub-component of the VHub.
NOTICE:
In addition to these components, the Aurora system components must be upgraded to the
latest rmware versions. These can be obtained from Aurora.

2.0 Installation
2.1 Installation
2.1.1 System Interface & Power (SIP) Card Installation
1. Turn the power supply’s battery circuit breaker OFF.
2. Unplug all inverter module connections (e.g. battery cable, remote temperature sensor).
3. Loosen the inverter module thumbscrews (Fig 2-1).
4. Slide the inverter module out of the power supply (Fig 2-2).
5. Loosen the two Phillips captive screws to remove the existing communications module from
the inverter module (Fig. 2-3).
6. Attach the SIP card to the sheet metal with the two screws from the communications kit (Fig. 2-4).

7. Plug the supplied 2 x 9 pin header from the communications kit into the header on the
inverter module (Fig. 2-5).
8. Line up the 2 x 9 pin header with the header on the SIP card (Fig. 2-6) and gently push the
SIP card into the inverter module.
9. Fasten the SIP card to the inverter module by tightening the two captive screws.
10. Reinstall the inverter module.
11. Make front panel connections (tamper, temperature sensor, battery, etc.).
12. Turn the battery circuit breaker back on.

Power supply addresses must be set to 1 even in the case of dual power supply setup. This is done via the
Smart Display on the power supply. Please refer to the appropriate power supply manual for more information:
XM2-300HP Technical Manual (Alpha p/n 017-877-B1).
NOTICE:

2.1.2 Alpha Optical Interface (AOI) Unit Installation
1. Mount the Alpha Optical Interface (AOI) unit in the enclosure. The AOI unit is placed next to
the power supply, between the power supply and the enclosure wall (Fig. 2-7). Attaching the
AOI unit to the shelf with two screws in the footer is optional.
2. Prepare a tap from the ber optic cable.
3. Insert the SFP into the SFP slot on the OE4130S-01 on the AOI unit (Fig. 2-8).
4. Attach the ber optic cables to the SFP. The included ber jumper cable can be used as the
nal connection between the service ber and the AOI (Fig. 2-8).
5. Attach the communications cable (Alpha p/n 875-190-26) (Fig. 2-8).
6. If installing an enclosure door to the Tamper Switch on the OSM1, remove the jumper from
the Tamper connection (Fig. 2-8).

2.2 Verication
2.2.1 AOI LED Verication
OE LED: The OE LED will blink 1-2 times per second when communication is active between
OE4130S-01 and the AOI.
A LED: The A LED will blink every 1-2 seconds when it is communicating with the out Port A.
B LED: The B LED will blink every 1-2 seconds when it is communicating with the out Port B.
2.2.2 SIP LED Verication
COM LED: The COM LED will blink when the power supply is responding to communication
requests from the AOI.
3.0 Remote Monitoring Using SNMP
Power supply data is transported through the OSM1 to the head-end via existing ber where an Aurora controller
module (the CX Controller) converts the data to a standard SNMP format. This data can then be accessed from
the operators’ power supply monitoring software, via SNMP queries through the IP address of the controller
module. The controller acts as a proxy to the OSM1 modules and connected power supplies. A single CX
controller can proxy up to 48 power supplies in a given system.
3.1 SNMP MIB Data Reporting
THe OSM1-connected power system status and alarming is reported through the standard SCTE-HMS
power supply MIBs as detailed below..
3.1.1 SCTE-HMS psIdent MIB
Power supply data is reported through the standard SCTE-HMS psIdent branch, which is
supported by all standard power supply management systems..
3.1.2 SCTE-HMS propertyTable
The propertyTable is limited to a select number of parameters for alarming, and the alarm
thresholds are preset.
