1.0 The Fiber Node Enclosure
1.1 Overview
The Fiber Node Enclosure (FNE) allows the exible conguration 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 airow 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

1.4 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.

D
Access Panels (2 side, 2 rear) are used to facilitate installation of cabling.
E
As needed, install passive splitters per manufacturer's instructions.
F
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 congured 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, sufciently 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 congured 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, conguration,
start-up and validation.

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.

MECHANICAL OR MOVING PARTS HAZARD
Keep hands clear of the fan openings. The cooling fans are thermostatically-controlled and may start when power
is applied.
To reduce the risk of electrical shock, connect the customer-supplied coaxial cable to the fan panel rst, then
connect the cable to the cable plant.
WARNING! ELECTRICAL HAZARD
