NetVanta 4300/4400 Series

 

 

NetVanta 4305 (DC)

The DC-powered NetVanta 4305 connects to a centralized DC power source via the four-position power connector on the rear of the chassis (see Figure 3 on page 18). The nominal input of the NetVanta 4305 is +24 VDC or -48 VDC. Power and ground connections require copper conductors and a ring lug.

 

Instructions for Connecting DC Power Source to the NetVanta 4305

 

 

Step

Action

1With the power disconnected, connect the primary power source to input A of the power connector.

2Connect a ground wire (fitted with a loop terminal end) to the grounding point using the screw provided. Connect the other end of the ground wire to a protective earth ground.

3If using a backup power source, connect it to input B of the power connector.

Power to the NetVanta 4305 DC System must be from a reliably grounded 24 or 48 VDC.

Use only copper conductors when making power connections.

Install unit in accordance with the requirements of NEC NFPA 70.

The branch circuit overcurrent protection shall be a fuse or circuit breaker rated minimum 48 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 and Gigabit Ethernet interfaces MUST NOT be metallically connected to interfaces that connect to the outside plant or its wiring. These interfaces are designed for use as intra-building interfaces 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.
