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 13 on page 30
). 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.
