NetVanta 3205 (DC)
The DC-powered NetVanta 3205 connects to a centralized DC power source via the three-position terminal
block on the rear of the chassis (see Figure 9 on page 29). Power and ground connections require copper
conductors and ring lugs.
Instructions for Connecting DC Power Source to the NetVanta 3205

•
Power to the NetVanta 3205 DC System must be from a reliably gr24 or
-48 VDC source which is electrically isolated from the AC source.
•
Use only copper conductors when making power connections.
•
Install unit in accordance with Article 400 and 364.8 of NEC NFPA 70.

The 10/100BaseT Ethernet interface
MUST NOT
be metallically connected to interfaces
which connect to the Outside Plant or its wiring. This interface is designed for use as an
intra-building interface only. The addition of primary protectors is not sufficient
protection in order to connect this interface metallically to OSP wiring.
To comply with GR-1089-CORE, Issue 3, this equipment
MUST
only be installed in a
DC-C (common) bonding and grounding environment. It may not be utilized in a DC-I
(isolated) bonding and grounding environment.
