Wiring the power redundancy (PDU+1)

2 Installing the Network Management Module

2.1 Wiring the power redundancy (PDU+1)

2.1.1 Power redundancy principle

Interconnect 2 Network Modules using the power redundancy port (PDU+1) with a standard Ethernet cable (not supplied).
Power the 2 Network Modules with 2 different feeds so that if one feed is down, the Network Module will still be powered ON and
alive, providing useful information on the power outage situation.
2.1.1.1 LEDs
2.1.1.2 Power redundancy connection with 2 modules
2 modules:
Interconnected with the PDU+1 port
Powered with 2 different feeds
Installing the Network Management Module – 10
• Off — no active redundancy
• Solid yellow — the PDU Network Module is powered by another PDU Network Module
through the redundancy port.
• Off — PDU Network Module is not connected to another PDU.
• Solid green — The PDU Network Module is connected to another PDU Network
Module power redundancy port.
Result with a power cut on FEED A = all the modules are powered by
FEED B
Result with a power cut on FEED B = all the modules are powered by
