Rackstamp, data center labeling field guide

GLOSSARY / 42 TERMS

Use the same words for the same things.

A shared vocabulary makes labels and records easier to interpret. These definitions explain how the terms are used in Rackstamp; consult the related guide for application details.

A/B feed designation
A site's label for power paths. The designation and any color legend must be tied to its documented design.Check textual feed identities against the power-path record ↗Govern the site's color legend ↗
Acceptance criterion
An observable condition used to decide whether a stated deliverable or work scope has been completed.State an observable audit criterion ↗Define what the receiving team accepts ↗
AIM
Automated infrastructure management. Systems that detect supported physical connectivity events and relate them to managed records; coverage depends on the installed hardware and integration.Compare supported connection detection with asset inventory ↗
Alias
Another name used for the same object, such as the equipment name displayed in an alarm system.Maintain asset aliases through moves ↗Cross-reference equipment and alarm names ↗Preserve provider and tenant references ↗
As-built record
A record of the installed arrangement at a stated revision. Compare it with later changes before assuming it remains current.Reconcile the delivered as-built package ↗Match a pathway to its drawing ↗Preserve later changes and final states ↗
Asset ID
An organization's identifier for an asset. Keep its relationship to the manufacturer's serial number and current location explicit.Keep asset identity separate from location ↗Verify an asset barcode or QR lookup ↗
BMS
Building management system. An alarm name may need a cross-reference to the physical equipment identifier.Map BMS names and points to physical equipment ↗
Breakout
A cable or connection arrangement that separates a higher-count connection into identified legs or ports. Use the actual assembly's mapping.Map the trunk, legs and remote ports ↗
CDU
Coolant distribution unit. Preserve the installed manufacturer's names for its connections and components.Map liquid-cooling hose connections ↗Relate cooling equipment to alarm names ↗
CMDB
Configuration management database. A source of configuration-item records and their relationships.Assign field ownership and reconcile conflicting records ↗
Color legend
A versioned mapping between a color and its intended meaning in a stated scope. Add readable text so color is not the only identifier.Define and maintain a scoped color legend ↗Keep color and textual power-feed identity connected ↗
DCIM
Data center infrastructure management. In these guides, the system used to hold relevant equipment, location, or connection records.Resolve physical-label and system-record disagreements ↗Maintain asset-to-location relationships ↗
Demarcation
The defined handoff point between parties or systems. Record the physical endpoint and the responsibility boundary.Identify the physical handoff and responsibility boundary ↗
Direct thermal
Printing on a heat-sensitive medium without a separate transfer ribbon. Suitability depends on the specific material and exposure.Compare print processes against the intended use ↗Record the material's actual application and service conditions ↗
Endpoint
The specific termination of a connection, including enough device, panel, and port context to identify it.Build a complete cable endpoint ↗Map PDU outlets to device inlets ↗
Exception
An unresolved discrepancy or a documented departure requiring an identified owner and disposition.Retain findings, decisions and unresolved closure ↗Keep uncertain record values visible ↗
False negative read
A target expected in the observed scope that the reading process fails to detect.Account for expected tags missed during a defined session ↗
False positive read
A detection interpreted as a target observation when it should not have been included, such as an RFID read from a neighboring rack.Test outside-area control tags and record decisions ↗
Ghost asset
A discrepancy in which a physical object and its expected inventory state do not agree, such as retired equipment that remains installed. Record the specific discrepancy.Check the physical state of retired equipment ↗Resolve disagreement between inventory and observation ↗
Group clearance
A label-layout parameter for spacing between port groups. Its software definition must be reconciled with the physical measurement.Check the datum and spacing between port groups ↗
Half-cut
A cutting operation that leaves the backing connected while separating label material; available behavior depends on the printer and stock.Control cut and feed choices without losing label pairs ↗Include output handling in the printer trial ↗
Identifier
The exact value used to distinguish an object or location within a defined scope.Define identifier meaning and scope ↗Resolve duplicate identifiers ↗
Label lifecycle cost
The cost of producing, applying, maintaining, replacing, and reconciling labels over a defined period and scope.Build a scoped labeling business case ↗Calculate cost per accepted printed label ↗
Label proof
An actual-size printed sample checked before issuing the full label batch.Reproduce the accepted printer setup ↗Check a full-size patch-panel strip ↗Test the exact legend in the available space ↗
LOA
Letter of authorization. In a cross-connect workflow, use the provider's authorized connection details and process.Preserve the provider's authorization reference ↗
Local and remote
Labels describing the two ends from a stated viewpoint. Keep that viewpoint consistent in records and examples.Choose local/remote or fixed-end label wording ↗
Location ID
An identifier for a place, such as a site, room, rack, or mounting position.Build a usable rack address ↗Record rack face and occupied units ↗
MAC work
Moves, additions, and changes. Here the term refers to infrastructure work, rather than a network interface address.Close moves, additions, changes and retirement ↗
Namespace
The defined scope in which an identifier is expected to be unique. A shortened value can need additional site or room context.Define where an identifier must be unique ↗Distinguish a scope omission from a real collision ↗
On-metal RFID tag
A tag designed for operation on specified metallic mounting surfaces. Verify the actual mounting and reading environment in the pilot.Qualify the actual tag mounting and read boundary ↗
Patch panel
A termination panel whose ports connect cabling. A port number needs its panel context.Reconcile panel identity, ports and strip layout ↗
PDU
Power distribution unit. Outlet identity is a separate field from the PDU's own identity.Identify the PDU and its exact outlet ↗Reconcile the PDU's A/B feed designation ↗
Port pitch
Spacing between defined corresponding points on adjacent ports, commonly their centers. State the datum and units used.Measure repeated port spacing and inspect cumulative drift ↗
Print batch
A controlled group of label outputs tied to a data revision, template, and production setup.Reconcile source rows, copies, rejects and reprints ↗Retain the printing configuration and proof ↗
PSU
Power supply unit. Use the inlet or PSU marking on the specific device.Match the device PSU or inlet to its supply cord ↗
Quiet zone
Blank space required around a machine-readable symbol. Use the requirements for the chosen symbol and printing application.Check symbol printing and scanner compatibility ↗
Rack unit / RU / U
The rack-position reference used by the equipment and the site's mounting convention. Record the face and occupied span as well as the position.Translate rack positions and occupied spans ↗
Record owner
The person or team responsible for maintaining and resolving a particular record or field.Identify who can resolve a disputed field ↗Assign ownership at contractor handoff ↗
Revision
The version of a policy, drawing, worksheet, or source used for a task.Maintain the naming policy and issuance rules ↗Check delivered schedule and as-built revisions ↗
RFID
Radio-frequency identification. A reader obtains an identifier from a compatible tag; an observation still needs interpretation and association with the correct asset.Design an RFID inventory and record-mapping pilot ↗Check the barcode or QR fallback workflow ↗
Thermal transfer
Printing that uses heat to transfer a marking material from a ribbon to the selected media. Media, ribbon, and settings must be compatible.Qualify the printer, ribbon and media combination ↗Match label construction to application exposure ↗
Verification evidence
The observation, document, test-result reference, or approved record used to support a specific conclusion.Record audit findings and closure evidence ↗Associate original test results with cable identities ↗
