1. Purpose The purpose of this Facilities Engineering specification is to establish guidance for identifying, marking and labeling Structures, Systems, Equipment, and Components (SSEC)

2. Scope This specification contains instruction for uniform identification, labeling, and marking of SSEC at DISA Enterprise Services locations. Applications include:

• Establishing standardized SSEC identification, labeling, and marking schemes

• Identifying, labeling, and marking new SSEC when installed

• Ensure uniform identification of SSEC across the enterprise

Within this specification, a ‘shall’ statement identifies mandatory elements and requirements. A ‘should’ statement is a recommendation that is based on standard industry practice and good business policy. In limited circumstances, the word ‘may’ is used when permission is granted rather than constituted as a requirement.

3. References. See Appendix 1

4. Definitions. See Appendix 2

5. General Requirements SSEC shall be labeled per operational requirements before being designated operable or in service.

Labeling of SSEC in areas where hazards exist (i.e., high structures and confined spaces) shall be evaluated against safety requirements. For example, to reduce personnel risk, some SSEC could be labeled as site conditions permit (e.g., shutdown), or when scheduled maintenance is performed.

5.1. Labeling

Labels shall be permanently attached and designed to withstand wear, erosion and corrosion. They shall be heat resistant in high temperature areas and corrosion resistant in acidic or caustic areas.

Position labels so they are readily visible and, oriented in a horizontal position on a flat surface, where feasible. Labels shall be legible without manipulation by site personnel. Large SSEC shall be labeled in multiple locations, in close proximity to where workers perform their tasks.

Labels or tags installed under this specification shall not interfere or alter existing manufacturer’s nameplate or code information.

Labels shall be mounted in such a way as to preclude accidental removal and located to eliminate any possible confusion as to the item being identified and shall not obscure other items nearby.

Label size shall be based on available lighting and anticipated reading distances. SSEC which require local operation during blackout or reduced visibility conditions shall be marked with reflective or glow-in-the-dark tape.

Labels shall not interfere with an operator’s ability to read the instrument, display, or gauge.

Version Date: 30 June 2017 Page 6 of 34

Minimum Technical Specifications for

5.2. Color Coding

Label colors shall provide a high contrast between characters and background to enhance legibility. Color coding for SSEC shall be assigned only one meaning per color scheme and shall be consistent.

5.3. Language

Use of SSEC unique identifiers (UIDs) and noun descriptions shall be consistent among SSEC labels, equipment lists, drawings, procedures, checklists, and load lists. Checklists, procedures, and installed labels shall use UIDs to describe the name and number nomenclature for the SSEC.

Abstract symbols shall be used only if they have a commonly accepted meaning for all intended users (e.g.

Brevity should not be stressed if the results will be unfamiliar to operating personnel. Words on labels should be concise and still convey the intended meaning.

5.4. Other Identification Systems

This specification is not intended to conflict with any other mandatory standard(s) or guidance affecting the data center environment. If conflicts are identified, DISA Facilities Engineering will make a determination on the governing standard(s) or guidance. This specification does not define identification, labeling, and marking standards for communications, data cabling, computing and storage enclosures, or non-raised floor IT equipment.

Identification tools such as Information Technology Service Management (ITSM), Data Center Information Management (DCIM), and Computerized Maintenance Management System (CMMS) shall include database fields (where applicable) to identify the standardized UID Number as specified herein.

These fields are not intended to supplant or replace other identification numbers already in use by other systems.

“Common” or “Legacy” and BAS Name information shall be retained in written and supplementary database field formats for historical cross-reference compatibility.

6. Facilities

6.1. Structures

6.1.1. Identification

DISA occupied space, on load-bearing columns (or posts), shall have column labels to identify the proper column number. This column number is considered a unique identifier (UID); an associated attribute that serves to uniquely define a quadrant around the specific column and abuts quadrants of adjacent columns.

Using an alphanumeric system, column UIDs shall designate A01 as the first corner column of the building as defined by current architectural and MEP drawings. UIDs shall reference the original A&E drawings, as applicable. For structures without internal columns (i.e., only four (4) corner columns), designate A01 for the whole structure. In absence of a column on quadrant boundaries provide ceiling-hung UIDs.

Version Date: 30 June 2017 Page 7 of 34

Minimum Technical Specifications for

6.1.2. Labeling

Column UIDs shall be a four (4) inch character, semi-gloss black lettering with the top of character not more than six

(6) inches below ceiling, concrete slab, truss line or typically accepted physical divider between workspace and ceiling line. UIDs may be applied using paint, adhesives, or other means that meet the required dimensions and characteristics mentioned above. UIDs shall be located on all sides with a minimum of two (2) opposing sides of each column; orientation lengthwise or widthwise of each room is not prescribed. For round columns, UIDs shall be located at N, S, E and W column locations.

6.2. Rooms, Cubicles, Partitions, and ISO Enclosures

All rooms, cubicles, partitions, and enclosures within each facility shall be labeled with the appropriate room, cubicle, or partition (UID) numbers at all entrances. Signage shall be posted immediately adjacent to the entrance designating the room, cubicle, or partition area being entered. Room numbers should be three (4) numbers in length, with the first number designating the floor number before the underscore and three numbers uniquely designating the room to match the archive drawings. For example, RM_1-101 (Room 101) is on the first floor and is the first room designated. Rooms may also retain their name; e.g., Battery Room as long as the name is in line with the current room function and is included as part of the room number; e.g., Battery Room RM_1-103. Cubicles, partitions, and enclosures should be four (5) numbers in length, with the first number designating the floor number before the underscore and the remaining numbers uniquely designating the cubicle, partition, or enclosure. For example, Cubicle 2000 is CUB_2-001 on the second floor and is the first cubicle designated. Subsequent cubicles numbers should be in sequential order; i.e., CUB_2-002, CUB_2-003, etc.

6.3. Raised Floor

In order to cross-identify Computer Room Air Handler (CRAH) units, In Row Coolers (IRC), Water Distribution Units (WDU), Humidifiers (HUM), Critical Distribution Panel (UDP), Static Transfer Switches (STSs), Power Distribution Units (PDUs), Remote Distribution Cabinets (RDCs), and other relevant miscellaneous facility equipment physically located on the raised floor, each unit or cabinet shall be tagged with its alphanumeric UID.

The IT unit or cabinet grid location should consist of one or more letters followed by three numbers. The numeric portion of the UID will include leading 0s. As examples, the unit or cabinet whose right front corner, (from the perspective of the unit or cabinet / the left front corner when looking at the front of the rack) is at AJ-006 will be named AJ006, the unit or cabinet whose right front corner is at AK-009 will be named AK009, the unit whose right front corner is at AV-002 will be labeled AV002, and the unit whose right front corner is at AC-014 will be named AC014 (Figure 2).

Figure 1 – Compliant Column Label

Version Date: 30 June 2017 Page 8 of 34

Minimum Technical Specifications for

If units or cabinets rest on more than one tile, the grid location for the units or cabinets can be determined by using the same corner on every unit or cabinet (the right front corner; from the perspective of the unit or cabinet / the left front corner when looking at the front of the rack). This grid location is determined not only from the right front corner of the unit or cabinet, but also by the ‘front’ tile upon which the unit or cabinet predominantly rests (front majority). As an example, in Figure 2, there are two Units that don’t line up with the grid: Unit 1 and Unit 2. Sample Unit 1 rests on four adjacent tiles with its right front corner resting predominantly on tile/grid AC-014. Its UID would therefore be AC014. Sample Unit 2 rests on six adjacent tiles with its right front corner resting predominantly on tile/grid AJ-006.

In data centers the floor number should be added as a prefix to the unit or cabinet number. For example, 3AJ006 is the label for the unit or cabinet whose right front corner is at tile AJ006 on the 3rd floor of the data center.

Figure 2 – Sample Unit/Cabinet Unique Identifier

6.3.1. Non-IT Systems, Equipment, and Components

For non-IT Systems, Equipment, and Components (SEC) on the raised floor, the grid location shall be captured on Line 1 of the SEC label as outlined under Section 7.

6.3.2. IT Equipment

For IT equipment on the raised floor, the UID label information shall be posted on the front and rear exterior of each rack or cabinet, on the rack unit’s top right side (top left as facing it) of the frame above the door. The minimum standard for these UID labels is machine-printed paper tags secured with clear plastic or acetate adhesive tape. Font style shall be bold sans serif font with a typical font size of 28.

Labels shall consist of a rectangular tag imprinted with one plus (1+) lines of information:

UID Number for the SEC in question. On the label, it is reflected with the Parent UID Number immediately following.

• For Line 4, the “Common” or “Legacy” name is optional. Double quotes will be used around “Common” or “Legacy” names to differentiate between BAS Device names in Line 4 and “Common” or “Legacy” names in Line 4.

• For Line 5, the BAS Device name is required when applicable. If an SEC has a BAS Device name, which can be found in the BAS OEM Manuals, it is a required field. If an SEC does not have a BAS Device name, then the field is left blank.

7.2. Unique Identifier (UID) Number

All systems, equipment, and components (SEC) shall be assigned a Unique Identifier (UID) Number.

Line 1 of Figure 7 – Compliant Label, designates the UID Number of the SEC to which the label is attached. The UID Number shall (unless otherwise noted) have four (4) fields with the 1st Field as the SEC Designator then underscore then 2nd Field the floor number, as the System Designator, and the 3rd and 4th Fields as Sequence Numbers, with dashes separating each field.

The first character set (1st Field) of the UID Number represents the SEC Designator shall be up to six (6) total characters in length. The first characters, one (1) to five (5), are alpha, and the last character is numeric. The alpha characters are the SEC Designators. The SEC Designators are required. Reference Appendix 3 for approved SEC Designators.

The second character set (2nd Field) of the UID Number represents the floor number. An underscore will separate the SEC Designator from the floor number.

The third character set (3rd Field) represents the System Number and shall be used to designate sequential SEC with the same SEC Designator (e.g., sequential distribution panels connected to a critical UPS bus would be distinguished as UDP_1-A-01, UDP_1-A-02, etcetera) and shall be alphanumeric.

The fourth character set (4th Field) is an additional Sequence Number, which shall only be used for specifically identified SEC Designators. When required, it shall be a single numeric character. For example, a distribution panel also has a sub-panel, the distribution panel would be referred to as DP_1-A- 01-01 and the sub-panel would be referred to as DP_1-A-01-02.

Examples:

PDU_4-B-06 (PDU on the 4th Floor connected to the B Bus, Unit # 6) MTS_1-CD-01 (Mechanical transfer switch on the 1st floor connected to both C & D Buses, Unit # 1) EDP_1-C-01-02 (Essential distribution panel on the 1st floor connected to the C bus, Unit #1 subpanel #2) CRAH_3-D-15 (CRAH unit on the 3rd floor connected to the D bus, Unit #15)

7.3. Physical Characteristics

7.3.1. Materials

Plastic Labels: Flexible engraving stock (aka Lamicoid or Phenolic) with at least a two-color plastic material to obtain the required color coding combination is the preferred material for permanent SEC labels described in Sections 7 and 8. Characteristics of flexible engraving stock include abrasion, heat, wear, and chemical resistance. Machine-printed identification information, if used, shall be indelible, environmentally stable, and chemically resistant. Machine-printed identification information is only allowed if spelled out in this

Version Date: 30 June 2017 Page 12 of 34

Minimum Technical Specifications for specification or by special permission through the Chief of Facilities Engineering or Chief of BOS Maintenance.

Metal Labels: Metal tags are acceptable for permanent equipment SEC labels described in Sections 7 and 8.

Paints or powder coatings used on these tags shall be environmentally stable, chemically resistant, and wear resistant.

Identification Tape: Commercially available tape products may be used for labeling of common SEC where detailed UID’s and other information is not necessary; for example, on insulated piping systems, labels indicating contents and direction of flow are generally sufficient.

Machine-Printed Identification Tags: On SEC subject to frequent modification or replacement (for example, power whips from a PDU to an IT equipment rack), machine-printed labels are acceptable. These typically print on a flexible form of machine-generated plastic-coated material, which shall be secured to the SEC in such a manner as to protect the labeling information from degradation.

Unapproved Materials: Materials which can be lost, damaged, rendered unreadable, easily removed, soiled or degraded by operating environment, or which are of a non-permanent nature shall not be used for labeling or identification purposes. This includes (but is not limited to) paper, paper in clear plastic protectors, and direct labeling of SEC with markers or paint.

7.3.2. Attachment

Adhesives: Adhesives may be used to secure labels or tags to SEC. Adhesives should securely fasten the label to the component without causing degradation to the SEC or the label. The adhesive shall be chemically compatible with the label material, the component material, and the environment. Adhesives shall not be used on stainless steel piping or components.

Wire: Bare wire may be used for attaching labels to SEC where use of adhesives is not practical and there is no risk of the bare wire becoming electrically energized (e.g., valve tags).

Cable Ties: Standard 50lb cable ties (a.k.a. zip ties, nylon ties, plastic ties, tie wraps) may be used for attaching labels to SEC where use of adhesives is not practical (e.g., valve tags).

Chain: Zinc plated general utility chain may be used for attaching labels to SEC. The type of chain shall be single-jack chain of trade size 20 or 18.

Screws or Rivets: Screws or rivets may be used to secure labels to SEC as long as the attachment does not cause degradation to the SEC or label. Screws shall be metal type, with size, length, diameter, head, pitch, and axis not prescribed, but sufficient to adequately adhere labels. Rivets shall be steel, with type and dimensions not prescribed, but sufficient to adequately adhere labels.

7.3.3. Character Design and Size

Labels shall be formed with upper and lower case letters using simple letter styles as reflected in Figures 8 - 1 1 . A bold sans serif font, minimum font size 24, is standard for SEC labeling purposes. The maximum standing viewing distance for minimum font sizes is 60 inches (from label to the eye of the standing individual). With this font size, a 3” x 5” label is recommended. Labels not visible from this distance will use bold sans serif font 28 (24 for Line 1 of 7). With this font size, a 4” x 6” label is recommended. No additional restrictions are set on other labels in order to allow flexibility in aesthetic design.
