Unit Installation NetVanta 6240/6250 Series HIG

Mounting Options

The unit may be installed in rackmount, wallmount, or tabletop configurations. The following sections provide

step-by-step instructions for rack mounting and wall mounting.

Rack Mounting the NetVanta

The NetVanta is a 1U-high, rack-mountable unit that can be installed into 19-inch or 23-inch equipment racks.

The following steps guide you in mounting the NetVanta into a rack.

ADTRAN recommends 1U (1.75 inches) of separation above and below the

NetVanta 6240/6250 Series unit. This spacing allows the unit to dissipate heat. The design

of the NetVanta 6240/6250 Series uses the chassis to distribute heat generated by the unit’s

internal cards. This design allows the unit to operate without a cooling fan, ensuring the

overall reliability of the unit.

• If installed in a closed or multi-unit rack assembly, the operating ambient temperature

of the rack environment may be greater than room ambient temperature. Therefore,

consideration should be given to installing the equipment in an environment compatible

with the maximum ambient temperature specified by the manufacturer.

• Installation of the equipment in a rack should be such that the amount of air flow

required for safe operation of the equipment is not compromised.

• Be careful not to compromise the stability of the equipment mounting rack when

installing this product.

• Consideration should be given to the connection of the equipment to the supply circuit

and the effect that overloading the circuit might have on overcurrent protection and

supply wiring. Appropriate consideration of equipment nameplate ratings should be

used when addressing this concern.

• Reliable grounding of rack-mounted equipment should be maintained. Particular

attention should be given to supply connections other than direct connections to the

branch circuit (e.g., use of power strips).

Instructions for Rack Mounting the NetVanta

Step Action

1 Attach universal rackmount brackets in the appropriate (either 19-inch or 23-inch) position using

the supplied screws.

2 To allow proper grounding, scrape the paint from the rack around the mounting holes where the

NetVanta will be positioned.

3 Position the NetVanta in a stationary equipment rack allowing 1U space above the unit for

ventilation.

4 Have an assistant hold the unit in position as you install two mounting bolts through the unit’s

brackets and into the equipment rack using a #2 Phillips-head screwdriver.

5 Apply power to the unit (refer to Supplying Power to the Unit on page 27 or Supplying DC Power

to the NetVanta 6250 on page 27 as appropriate).
