32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- TIA-942 scope
- A voluntary standard for data centre telecommunications infrastructure covering design, installation, and audit criteria, including topology, redundancy, and reliability levels.
- Normative requirement
- A 'shall' statement in TIA-942 that must be met; auditors verify compliance with these mandatory clauses during an internal audit.
- Redundancy level N
- Basic capacity with no spare components; any component failure causes downtime. It represents the minimum capacity to support the critical load.
- Redundancy level N+1
- One additional component beyond the minimum required, allowing maintenance but not concurrent failure of critical components in the same path.
- Redundancy level 2N
- Two complete independent paths for power and cooling, allowing concurrent maintenance without affecting the critical load.
- Redundancy level 2(N+1)
- Two independent paths, each with N+1 redundancy, providing fault tolerance and concurrent maintainability for the highest availability.
- Concurrently maintainable
- A system design where any component can be removed or serviced without shutting down the critical load, typically achieved at 2N level.
- Fault tolerant
- A system that can sustain a single failure without affecting the critical load, typically achieved at 2(N+1) level.
- Entrance room
- The space where telecommunications cables enter the data centre and connect to the external network; it is the demarcation point.
- Main distribution area
- The central point in a data centre where backbone cabling connects to horizontal cabling; it houses core switches and routers.
- Horizontal distribution area
- An area that connects the main distribution area to equipment distribution areas via horizontal cabling, often containing switches.
- Audit independence
- The principle that auditors must not audit their own work and must remain free from bias to ensure objective audit conclusions.
- Risk-based audit planning
- Prioritizing audit activities based on the assessment of risk, considering likelihood and impact of nonconformities in data centre infrastructure.
- Audit criteria
- The set of policies, procedures, or standards such as TIA-942 against which audit evidence is compared to determine conformity.
- Audit scope
- The defined boundaries of an audit, including locations, systems, processes, and time period to be examined.
- Audit programme
- A documented set of audit activities, schedules, and resources planned for a specific period to achieve audit objectives.
- Audit evidence
- Records, statements of fact, or other information that are relevant to the audit criteria and verifiable.
- Audit finding
- The result of evaluating audit evidence against audit criteria; it can indicate conformity or nonconformity.
- Major nonconformity
- A nonconformity that affects the capability of the management system to achieve intended results, often requiring immediate corrective action.
- Minor nonconformity
- A nonconformity that does not significantly affect the management system's capability but should be corrected to prevent escalation.
- Observation
- A finding that is not a nonconformity but indicates a potential weakness or opportunity for improvement in the audited area.
- Audit report
- A formal document that presents the audit purpose, scope, criteria, findings, conclusions, and recommendations to stakeholders.
- Sampling in audit
- Selecting a subset of items from a population to gather evidence when examining the entire population is impractical.
- Interview technique
- A method of gathering audit evidence by asking open-ended questions to personnel to understand processes and verify compliance.
- Walkthrough
- A step-by-step observation of a process or system to verify that procedures are implemented as described.
- Corrective action
- Action taken to eliminate the cause of a nonconformity and prevent its recurrence, often requiring root cause analysis.
- Root cause analysis
- A method to identify the fundamental reason for a nonconformity, using tools like 5 Whys or fishbone diagrams.
- Follow-up audit
- A verification activity to confirm that corrective actions have been implemented and are effective in resolving the nonconformity.
- Continual improvement
- The ongoing effort to enhance the audit programme and data centre performance using audit results, trends, and feedback.
- Management review
- Top management's evaluation of audit results, corrective action status, and overall performance to ensure suitability and effectiveness.
- Audit records
- Documented evidence of audit activities, findings, and follow-up actions, retained to demonstrate audit process integrity.
- Effectiveness check
- An evaluation to determine whether a corrective action has successfully prevented recurrence of the nonconformity.
