Utilize an in-cabinet Uninterruptible Power System (UPS) for
smaller POPs.
Utilize a common UPS for protected power for POPs serving a
base with more than 250 seats.
Install the NMCI Technical Power Panel (TPP) in the equipment
room.
The NMCI Contractor typically does not install transformers or other
electrical equipment within the POP/ER that would change the room type or
affect the operation of the network equipment. Include language within new
construction contract documents that allows the NMCI contractor to install
equipment prior to beneficial occupancy.
Equipment for the POP room is deployed by the NMCI Contractor
in standard packages based on the number of seats. The equipment is typically
delivered in enclosed cabinets 610 mm (24.0 in) across the front face and 952
mm (37.5 in) in depth.

Location. The ideal location of the NMCI POP is near the base
Telecommunications EF/DP. Typically, POPs should be located away from
exterior walls, areas subject to flooding and sources of electromagnetic
interference (transformers, motors, x-ray, induction heaters, arc welders, radio,
radar) such that interference is less than 3 V/m across the frequency spectrum.
Generally, separate rooms with equipment located on opposing walls will satisfy
this requirement.
In addition, POPs shouls not be adjacent to mailrooms as defined
in the antiterrorism/force protection (AT/FP) guidelines of UFC 4-010-01, DoD
Minimum Antiterrorism Standards for Buildings.
2-2.6
Size. The nominal room space allocations for the NMCI POP
facilities are as indicated in Table 2-1. This table contains the requirement for
data equipment only.
Communications cabinets require a minimum of 610 mm (24.0 in)
of clearance to the front, rear and sides of the cabinet although 914 mm (36.0 in)
is preferred. This space can be shared with work areas for nearby cabinets or
electrical equipment. The Uniform Federal Accessibility Standards (UFAS) and
Americans with Disabilities Act Accessibility Guidelines (ADAAG) requiring 914
mm (36.0 in) clearance between equipment in telecommunication rooms is
excluded under Section 4.1.4, paragraph 4, "General Exceptions" in UFAS and
under Section 4.1.1, paragraph 5 "General Exceptions" in the ADAAG. NFPA 70,
the National Electrical Code (NEC) requirement for 914 mm (36.0 in) of
workspace for electrical junction points and pull boxes still applies.
