1.0 The Fiber Node Enclosure

1.1 Overview

The Fiber Node Enclosure (FNE) allows the exible conguration necessary to meet a wide range of applications,

including traditional and advanced Hybrid Fiber Coax (HFC), FTTx ber deep, Wi-Max networks, wireless outdoor base

stations, wireless IP access, and bulk power.

Cable Management System

The FNE is designed to accommodate customer-supplied nodes and passive splitters.

Cables enter and exit the enclosure via the polymer pedestal and trenched conduit.

Access panels on the side and rear of the enclosure allow technician access to the existing cabling or to add cabling as

future expansion demands.

Considerations:

• Where possible, select a site above the 100-year ood plain, and away from houses.

• Place in a shaded location to minimize the effects of solar loading.

• Locate in an area where airow can be maximized.

• Avoid locating the enclosure where it is an obstruction and would inhibit visibility.

• Locate the enclosure away from sprinkler systems or other sources of forced water.

• Locate the enclosure out of the prevailing wind to minimize the buildup of snow or the accumulation

of wind-borne dust.

• Evaluate the soil conditions for suitability for the installation of the vault.

• Ensure cabling has been run and terminated at the site.

• Contact a cable locating service, the local utility, and adjacent building supervisors to ensure installation location

and cable routing does not interfere with existing utility connections.

1.3 Site Selection

1.0 The Fiber Node Enclosure, continued

1.4 Installing the Vault

Follow the vault manufacturer's instructions and local codes with respect to site excavation, trenching, ll materials and

creating cabling access ports in the vault. At this time, prepare the site for the installation of the enclosure grounding

system per the instructions in Section 1.5, Grounding.

1.5 Grounding

Per the National Electrical Code (NEC), the grounding system for the FNE consists of a connection via a #6 bare

copper wire between the enclosure ground point and a single copper rod, 1/2" diameter x 8' long, driven into the

ground at least 2' from the vault (or pad). The copper wire is lugged on the end that attaches to the enclosure and is

connected to the ground rod by a connector that is suitable for direct burial.

Route the #6 bare copper wire from the enclosure through the vault (or pad) by means of the cable pass-through and

out to the ground rod.

1.6 Installing the Enclosure On the Vault

The enclosure is shipped from Alpha Technologies packed in a shipping carton.

Tools required:

• Torque wrench with 3/4" socket

• Ratchet set with extension

• Enclosure door key

• Vapor barrier material (if enclosure is being placed on a precast pad)

• Utility Knife

Cable pass-through

If the vault is not supplied by Alpha Technologies, and does not have a pre-cut pass-through in

the lid, it will be necessary for the installer to cut a pass-through into the lid before installing the

enclosure.

NOTICE:

Procedure:

1. Unpack the enclosure.

2. If installing the enclosure on a precast pad, position the 25-year vapor barrier material over the pad, and make all

necessary cutouts. If the enclosure is being installed on a polymer vault, no vapor barrier material is needed.

3. Place the enclosure into position on the vault lid.

4. Route any pre-run cables into the enclosure and secure the enclosure to the ber vault lid by means of four (4)

customer supplied 3/8"-16 stainless steel bolts, at washers and lock washers. Tighten to a torque value of 19 to 20

lb-ft.

5. If vapor barrier material is used, trim the vapor barrier material around the perimeter of the enclosure with a utility

knife.

031-347-C0-001, Rev. A (02/2017)

Remove node mounting bracket from rear wall of enclosure. Use wrench and 7/16" socket

to remove 2 stainless-steel bolts from each of the upper and lower mounting anges.

Attach node to bracket per manufacturer's instructions.

Reattach bracket to mounting anges.

Access Panels (2 side, 2 rear) are used to facilitate installation of cabling.

As needed, install passive splitters per manufacturer's instructions.

Removable lid, 4 x 1/4-20 nuts; requires 7/16" wrench.

1.7 Populating the Enclosure

The node mounting bracket [B] accommodates a variety of nodes. The FNE is also congured with horizontal and vertical

mounting brackets [E] allowing the addition of passive splitters per the requirements of future system expansion. The

enclosure lid is removeable and, if need be, can be removed to facilitate installing and splicing the node.

Four sliding access panels [D] are located on the rear and side of the enclosure. To use a panel, sufciently loosen (do

not remove) the four 1/4-20 nuts at the corners of the panel to allow the panel to slide toward the front of for the side

access panels and to the closest side for the rear access panels the enclosure.

The FNE is congured with a removable lid [F] to facilitate installing and splicing the node. The lid is held in place by 4

(four) 1/4-20 nuts located in the inside corners of the enclosure. To remove the lid, unplug the fan kit from the cable plant,

and with a 7/16" wrench remove the 4 (four) 1/4-20 nuts from the inside corners of the lid, lift the lid off and set aside. To

reattach the lid, reverse the above procedure.

Follow the manufacturer's instructions with regard to node and/or passive splitter installation, connection, conguration,

start-up and validation.

2.0 Optional Fan Kit

The FNE can be congured with an optional factory-installed lid-mounted cooling fan kit (Alpha p/n 746-738-20-001). The

kit is comprised of two fans mounted inside the lid and powered by AC voltage provided by the cable plant. In the event

the kit requires service or is added after the initial commissioning of the system, follow the appropriate procedure below.

4 (four) 1/4-20 Keps nuts and remove the lid.

2. Set the lid upside down on its roof.

3. Set the fan panel on the lid over the installed

studs.

4. Use a wrench with a 1/4" socket to install the 3

(three) 6-32 onto the studs in the lid.

5. Connect the customer-supplied coaxial cable to

the fan kit.

6. Replace and secure the lid on the enclosure.

7. Connect the coaxial cable from the fan kit to the

cable plant.

8. Secure the enclosure.
