Powering the 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 5 on page 21 ). Power and ground connections require copper
conductors and ring lugs.
Instructions for Powering the NetVanta with Octal PoE Upgrade
Step Action
1 Plug the 2-pin connector from the PoE Power Supply into the PoE receptacle on the rear panel of the
NetVanta unit.
2 Plug the PoE Power Supply’s power cord into the receptacle on the power supply.
3 Connect the 3-prong plug of the PoE Power Supply’s power cord to the proper receptacle.
4 Plug the NetVanta’s power cord into the 100-250 VAC, 50/60 Hz receptacle on the rear of the unit.
5 Connect the 3-prong plug of the NetVanta’s power cord to the proper receptacle.
The NetVanta 3205 DC is designed to operate with a nominal operating voltage of
-48 VDC or ±24 VDC and a minimum operating voltage of ±20 VDC. The NetVanta 3205
DC will not be damaged by any steady state voltage between 20 VDC and 56.7 VDC in
magnitude.
• Power to the NetVanta 3205 DC system must be from a reliably gr24 or
-48 VDC source that 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 branch circuit overcurrent protection shall be a fuse or circuit breaker rated
minimum 60 VDC, maximum 10 A.
• A readily accessible disconnect device, that is suitably approved and rated, shall be
incorporated in the field wiring.
• Maximum recommended ambient operating temperature is 50
°
C.
The 10/100Base-T Ethernet interface MUST NOT be metallically connected to interfaces
that 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.
