Workbook tab: 04 Rack face and U. The workbook includes all 30 registers.

Rackstamp provides editorial field guidance. IDs, cases, and worksheet entries are fictional examples unless identified otherwise. Distinguish local conventions from adopted standards. Source notes describe the evidence scope; a linked overview is not the full standard or a project approval.

## Before you start

1. Collect the complete rack address, asset identity, relevant elevation revision, and the position semantics used by each record system.
2. Identify permitted front and rear observations and note any parts of the footprint that cannot be accessed or seen.
3. Find the owner who can approve elevation corrections and any translation used by inventory imports.

## Complete the register

1. Enter Rack and Asset ID before interpreting the U value so the row cannot accidentally describe a neighboring device.
2. Record the complete occupied-unit range and height using the supported observation or installation evidence.
3. Enter Mounting face from the applicable semantics; record the viewing side of photographs separately in the evidence notes.
4. Write the Position rule in words, then derive Record position under that rule rather than copying the most visible U number.
5. Link the elevation, observations, and any source-to-inventory translation that explains the proposed correction.
6. Record the verifier, completed date, and status after both identity and convention have been checked; name any unresolved footprint or system update.

## Walk through the example

The original fictional row identifies AST-008421 in DC01/H1/R014. Its observed footprint is U23–U24, height 2U, and the record rule is lowest-numbered occupied U. Under that stated rule, Record position is U23. The front and rear views in the diagram refer to the same asset and do not create different positions. The mounting face remains Front even if a supporting observation is made from the rear. Use DEMO-ELEV-R014 revision 2 as the example evidence reference; a real row needs the actual released elevation and permitted observations. If another system records the upper unit, record its meaning and translation separately instead of declaring its U24 value wrong without context. The verifier should reconstruct the complete span from the worksheet and find the intended equipment in the approved views. Keep an inaccessible boundary or unconfirmed translation open rather than carrying the fictional example's status into a completed record.

## Handle common exceptions

### The drawing and inventory use different position meanings.

Document each meaning and the common observed span, then obtain the system owners' translation decision before changing values.

### An item is mounted outside numbered rack units.

Record the actual mounting location and supported system representation; escalate a mandatory U-field limitation.

### The rear photograph shows connectors but not the mounting reference.

Label it as rear-view evidence and obtain separate support for mounting face instead of inferring Rear mounting.

## Review and close

1. Confirm that the occupied span, height, and position are mutually consistent under the stated rule.
2. Check that front and rear evidence refer to the same physical asset where they are meant to do so.
3. Preserve non-U mounting descriptions instead of inventing numbered positions for them.
4. Review any apparent overlap against current and historical records before changing coordinates.
5. Check that the source elevation or import will not restore the superseded interpretation.

## Fields and fictional filled example

| Field | What to record | Fictional example |
| --- | --- | --- |
| Rack | Approved rack identifier. | DC01/H1/R014 |
| Asset ID | Identity of the equipment being located. | AST-008421 |
| Mounting face | Primary face used in the installation record. | Front |
| Occupied units | Full numbered equipment footprint. | U23-U24 |
| Height in U | Number of occupied rack units. | 2 |
| Position rule | Reference used to select one position value. | Lowest-numbered occupied U |
| Record position | Value entered under that rule. | U23 |
| Owner | Role responsible for the elevation. | Rack documentation lead |
| Evidence | Elevation and observation references. | DEMO-ELEV-R014 rev 2 |
| Verifier | Person checking both face references. | Example reviewer |
