DD Form 2490-12 occupies a particular place in Defense recordkeeping. Its title is DD2490-12 NETWORK PLANNING AND CONFIGURATION DATA - SWITCH MEMORY CONTROL . This form has not been set up to work with a text-to-speech reader. Contact the Department of Defense Forms Manager for further details if this access is required., and it exists to Network Planning and Configuration Data - Switch Memory Control. What the DD prefix records is an administrative judgment made long before your copy was printed: this transaction was determined to be common to the whole Department rather than peculiar to one service, and so the documentation of it was standardized at Department level.
The practical effect of Department-level issue is interoperability. not stated establishes the requirement across the Defense enterprise; not stated keeps the document current for all of it. No service maintains its own variant, which means a completed record travels between components — service to agency, agency to joint command — and arrives in a format the receiving office already knows how to read.
The edition in force is not stated, carried by the publisher as not stated, and edition discipline is stricter on a Department form than most people expect, precisely because supersession happens everywhere at once. There is no interval during which one service still works from the previous layout while another has moved on.
The sequence printed on the form is the sequence in which a reviewer will read it, and the two should agree. Header data frames every entry below it; the substantive fields depend on that frame; the certification stands at the end because its whole function is to vouch for what came before. Entries made out of sequence commonly contradict entries made earlier.
Check the edition date before you type anything, against not stated. Old blanks accumulate in shared drives for years, and the cost of one is not obvious until a reviewer cannot find a field. Because DD forms are revised centrally and replaced across the Department in a single action, there is no component still tolerating the old layout as a local practice.
Fill all of it, marking inapplicable items N/A. A record with gaps cannot later demonstrate whether the gap was a decision or an oversight, which is exactly the ambiguity documentation exists to remove. Dates go in the form's own format — on a document that crosses service lines, an ambiguous date is a real hazard rather than a pedantic one.
The Privacy Act Statement is not boilerplate appended for legal cover; it is the mechanism by which a statutory obligation is discharged at the moment of collection. When the government asks an individual for personal information, it must state the authority under which it asks, the principal purpose, the routine uses to which the data may be put, and whether answering is voluntary or mandatory. Those four disclosures are placed ahead of the data fields deliberately, because the point of telling you is to inform a choice you have not yet made.
The signature converts entries into an attestation, and that is why its form is prescribed. Ink, or a digital signature carrying a credential that identifies the signer — commonly issued on a Common Access Card. Typed characters in the box satisfy neither standard, because the whole value of a signature lies in being difficult to produce on someone else's behalf. Date it as you sign; an undated attestation cannot be placed in the sequence of events.
The defects that return forms are the same ones year after year: a superseded edition, required fields left blank, handwriting that fails on reproduction, dates in a convention the form did not ask for, and certification without a signature or without a date. Where a specific field is genuinely unclear, the instructions printed on the form come first and not stated governs where the two do not agree.
Download the form
What you can download: PDF. The form runs 1 pages and asks for approximately unknown entries. The plurality of formats is deliberate: Defense distribution has never been able to assume one operating environment across the whole force.
Fillable and printable are not two presentations of one file but two different objects. One holds your entries as structured data within the document; the other is a static picture meant to meet a pen. Since a DD form frequently moves outside the organization that created it, the durability of the entry matters more here than on a record that stays in one drawer. Typed text reproduces indefinitely; handwriting degrades at every copy.
The xfdl file is a survival from an earlier phase of Defense form automation. Xfdl is the IBM Lotus Forms format, and for a long period it was the Department's standard for electronic forms — fielded broadly enough that it still appears in distribution sets today. It opens in IBM Lotus Forms Viewer or a compatible client and nowhere else; a pdf reader will report it as damaged, which is not a fault in the file.
Nothing here is charged for. Published Defense forms are public documents and distribution carries no fee, in any format. One caution about software: fill the form in a desktop pdf application rather than a browser tab. Browser-embedded viewers implement field behaviour inconsistently, and the failure mode is silent loss of everything you entered.
Route the executed form as not stated or local guidance directs, and retain a duplicate first. Cross-component routing is ordinary for DD forms, which is precisely why a personal copy earns its keep: the receiving office may belong to an organization you have no standing to query about a missing document.
Cross-referenced documents are found by series and number, with nothing further required. That the DD sequence is unified across the Department means a cited number identifies one form and no other, which is the practical payoff of centralizing the numbering in the first place.
Procedures that touch both Department and service processes will cite forms from both sequences, and the coincidence of numbers between them is exactly that — coincidence. An Army proponent maintains the DA series for the Army; not stated or another Department office maintains the DD series for the whole Department. Two independent registries, two independent numbering runs, no correspondence at any value.
Understanding why editions change explains why checking them is not optional. Revision follows directive reissue, changes in what data is required, and amendments to mandatory notice text — decisions made at Department level and communicated through publication rather than notification. The file you saved does not update itself, so the edition date at download is what you rely on.
What you have here is the document and a description of it, which is a different thing from guidance. This page is not an organ of the Department, gives no legal or procedural advice, and makes no representation about the outcome of any filing; the offices that administer the requirement are the only ones positioned to answer that. Applicability, eligibility and procedural questions belong to not stated, to your servicing personnel office, or to the office designated in not stated.
