3.2 General Narrative

The DISA Enterprise Computing Facility at Mechanicsburg, PA, is located in Building 308 in the center of the installation, Naval Support Activity Mechanicsburg. . Construction of the facility was completed in 1988. The building itself is a two story steel structure with concrete masonry outside walls which are covered with a light colored sheet metal finish. The facility is connected to Building 309, a WWII wooden warehouse that has been converted to an administration facility, by an enclosed passageway, at the ground level, that is commonly referred to as the link. The downstairs of the computer facility houses the major mechanical and electrical systems, a SCIF for the NDE, the building control center, a tape storage area, a loading dock, a main entrance guard area, an atrium, and the main building break room. Both floors of the facility have major restrooms for both sexes. There is one freight elevator in the atrium area. The upstairs of the facility is dedicated to the raised floor spaces. The main computer room is approximately 40,000 ft2. 6,500 ft2 of that is being subdivided to create a SCIF space for the NDE. There are three other small spaces in the upstairs that serve as controlled areas for communications. Four small offices are located immediately adjacent to the upstairs atrium area.

3.3 Existing Electrical

3.3.1 Existing Medium Voltage Electrical System

Utility power is fed to building 308 via the one and only base substation located near the South perimeter fence. Electrical power for the facility is provided via a 12,470-volt primary power service feed directly into the electrical room through an external high voltage automatic transfer switch. There is only one electrical feed coming into the building from an exterior switch located on the east side of the building. The building is supported by a redundant utility configuration, but is ultimately limited to a single feed into the building. The host installation has completed the additional circuit work providing an additional path of site power to the building. When the new feed is connected to the facility, we will not have a single point of failure due to both back up lines in the same physical space.

There are three (P-1, P-2, and P-3) 2500/3333 KVA Westinghouse transformers, Class AA/FF/. Buss duct is 4,000 amps. The transformers are 12,470 delta/480wye. P-1 and P-2 power the “critical load” through the UPS distribution system. P-3 is for the “non-critical” essential load. All three switchbanks have 4,000 amp main breakers.

3.3.2 Existing low Voltage (480 V) Electrical System

A UPS system upgrade was conducted with new equipment coming online in September 2001. Six new Powerware Plus 750kVA modules configured on two primary busses through a System Bypass Module (SBM) which contains five circuit breakers and a static switch. The system design allows the load to be split between the two output distribution systems (busses). The UPS Upgrade Project (FY10), added an additional two (2) 750kVA/675kW modules to each bus to maximize the capacity of the critical bus. Each new module installed separate and complete we-cell batteries to support the minimum battery duration of the system. The new UPS equipment matched the model of the existing UPS equipment in the building. As part of the project, all pending firmware upgrades were installed on the existing modules. The site is now supported with five (5) 750/675kW modules per critical bus to provide a 2N+1 configuration. There is currently enough UPS capacity to allow a hot-tie transfer between the two output distribution systems – meaning that if all UPS modules to one of the critical busses became inoperative, the tiebreaker could be manually closed and the entire critical bus (‘A’ and ‘B’) would be powered by the other critical buss. If the facility load increases to approximately 1800A on each of the output busses, the UPS system will only operate as a parallel-redundant system without the afore-mentioned capability.

The battery system consists of ten strings of C&D Technologies Model XT2LC-23 flooded cell batteries, with each string consisting of 192 cells. Each jar contains 2 cells, for a total of 96 jars per string. The UPS system is rated for 15 minutes of reserve time at the rated output of 750kVA. Each UPS module is equipped with a battery string that is connected to a common DC switchboard. The DC distribution system is divided between two (2) switchboards. The original UPS modules and associated DC switchboard is rated at 6000A, 500VDC and includes a center collector bus with six (6) 2000A breakers. The new UPS modules installed in 2010, include a switchboard rated at 2000A, 500VDC and includes a center collector bus with four (4) 2000A breakers. Each UPS DC feeder breaker contains a shunt trip device that is controlled from the UPS. This provides fault protection for the DC system in the unlikely event that a UPS rectifier fault condition is encountered. This switchboard configuration allows any combination of batteries or UPSs to be online while a battery string or UPS is out of service for maintenance. If utility power and generator power become unavailable, the batteries would support the critical loads until power is restored. An Alber BDS-256XL battery monitoring system (not fully compliant with Facilities Standards) was installed on the existing battery configuration between Sep and Dec 2008.

Each UPS bus has a planned total capacity of 3000kVA. The combined load on the two busses as of Dec 2011 was 1921kVA. Each UPS modified to increase power factor from .8 to .9 was completed in January 2009. As of December 2011, critical “A” UPS bus load is 990kVA/891kW, critical “B” bus load is 931kVA/838kW.

The essential electrical distribution system has two primary distribution buses. Bus ‘P-1’ and Bus ‘P-2’. Each bus feeds 5ea - 750kVA UPS modules that have a common output buss (critical buss A and B). Critical buss ‘A’ and ‘B’ are connected via a normally open tiebreaker. Each critical bus is totally independent of the other. The overall UPS output distribution system is comprised of six (6) output distribution panelboards per critical bus and in turn feeds all of the PDU’s located throughout the raised floor areas.

3.3.3 Generator System

There are five 750 KVA diesel powered emergency generators, model 3512 Caterpillar. They are aligned in a parallel redundant system. There are two Antron 750 KW loadbanks, model #K575D16882, that are permanently mounted and used for testing the generators and individual UPS modules. The generators were installed as a part of the original building construction in 1988.

3.3.4 Fuel System

The generator engines run on diesel fuel. The major reserve tank has a 10,000-gallon capacity. There is only one fuel supply system.

3.4 Existing Mechanical

3.4.1 Chilled Water Supply

The existing chillers and CHW pumps are new as of July 2007. There are 4 each, 540 ton, York, model YKDHDGQ7-CRFS, centrifugal chillers. The chiller system’s redundancy level is at 1080 ton at 2N.The chiller distribution system is run off of redundant chilled water pumps to feed chilled water to the facility cooling system. The distribution for the chilled water is fed to both the first and second floors. The 2nd floor has a loop under the raised floor as well as above the ceiling. The above ceiling loop was installed during the chiller project and the build out of the customer area on the 2nd floor in 2007.

3.4.2 Condenser Water System

The existing condenser towers are new as of July 2007. There are 4 ea. 500 ton, EVAPCO, model AT212-724 cooling towers. These towers have 2ea. 3030 gpm pumps that operate at 2N redundancy. The towers are on the 2nd floor of the facility and are connected together with a main sump which gravity feeds down through the roof to the condenser water pumps and to the chillers. This system is also 2N redundant with only 2 towers and 1 pump required at the current load in the facility; however because of the pipe routing all of the towers are activated when chilled water is required.

3.4.3 Hot Water System

The boiler was replaced with a new boiler in 1997. Heating is provided by a two-pipe hot water circulation system. The boiler is just serving the AHU at this time for comfort heating.

3.4.4 Computer Room Air Handlers

All of the existing or original CRAH units have or will be replaced. The CRAH units for the main computer room on the second floor, rooms 214, 203, and 203A, will be replaced by the end of FY14.

3.5 Existing Controls

In 2007 the chiller plant was updated to Delta controls. Several SKIF’s have been installed in the facility and need to be monitored by the BAS.

The existing controls for the rest of the facility are the existing pneumatics that are original to the facility.
