    DIGITAL LOCKOUT/TAGOUT · DATA CENTERS

    Prove LOTO control across uptime-critical data center work.

    Zentri centralizes procedures, worker sign-on, power dependency checks, isolation verification and closeout evidence in one traceable record.

    The problem

    LOTO control gets harder when every isolation can affect uptime.

    When data center LOTO spans facilities teams, contractors and critical power systems, disconnected records make it hard to prove what was isolated, whether redundancy remained intact and what was safe to release.

    Question
    • EQUIPMENTWhich asset is being isolated?
    • DEPENDENCYWhat downstream systems are affected?
    • REDUNDANCYIs the backup path still active?
    • WORKERSWho is signed on?
    • VERIFYWas isolation verified in the field?
    • STATUSWhat is still energized or at risk?
    • CLOSEOUTIs the asset ready to release?

    Zentri answers each question from one connected LOTO record.

    Featured capability

    See every dependency before you isolate.

    ImpactView maps the power chain from utility feed to rack, helping teams understand downstream impact before a lockout begins.

    Product workflow

    One traceable record from planning to release.

    Each step adds status, ownership and evidence to the same controlled lockout record.

    01
    Procedure
    Approved LOTO procedures linked to data center assets, energy sources and isolation points.
    02
    Plan
    Create lockout plans for maintenance windows, electrical work, commissioning or contractor activity.
    03
    Assess impact
    Review dependencies, redundancy paths and affected downstream systems before isolation.
    04
    Sign-on
    Record facilities teams, contractors and authorized workers under the lockout.
    05
    Verify
    Track isolation points, energy sources and field verification before work begins.
    06
    Monitor
    Keep active lockouts visible across plant rooms, white space, electrical infrastructure and shifts.
    07
    Release
    Capture closeout, sign-off, return-to-service status and the completed record.
