The OIB is field replaceable. The iRPD, power supplies, RF cables, power cables, and OIB mounting screws
must be removed in order to remove the OIB from the housing lid.

Intelligent Remote PHY Device

In a Remote PHY network, both downstream and upstream PHY functionality are located at the traditional
HFC node site. The node is the optical to electrical transition point in the network.
The Intelligent Remote PHY Device (iRPD) is a plug-in module in the node. It is intended to interact with
the cBR-8 router, via a digital physical interface card (DPIC) installed as a module in the cBR-8. It supports
these features:
• Full spectrum DOCSIS 3.0 support
• Full spectrum DOCSIS 3.1 support
• Converged broadcast, narrowcast, and VOD video support
• Out of Band (OOB) signaling support
• Dual 10GBE SFP+ backhaul connectivity
• Support of Daisy Chain architecture topology
• CCAP support
• Support of optical overlay architectures
Typically, it takes about 7 minutes after power is applied for an iRPD to go online.

Power Supply Module

The power supply module converts a quasi-square wave, 50 – 60 Hz AC input voltage into four well-regulated
DC output voltages. The supply is an off-line, switched-mode power supply with a large operating range.
This reduces service outages by converting long duration AC surges into load power. The power supply is a
constant power device, meaning that it automatically adjusts its internal operating parameters for the most
efficient use of the different levels of input voltage and current it will receive within the cable plant.
The DC output voltages generated by the power supply, at given load currents, are shown below:

Theory of Operation
OS is ok but node control software is not
running or is stuck. If this condition persists
for more than a minute or two after power
up, check all the cables connecting the lid
and launch amplifier. Try cycling power.
This condition should not be possible unless
Heartbeat LED is damaged.
