Warnings, Cautions, and Notes

Warning Highlights an essential operating or maintenance procedure, practice, condition, statement, etc., which, if not strictly observed, could result in injury to, or death of, personnel or long term health hazards.

Caution Highlights an essential operating or maintenance procedure, practice, condition, statement, etc., which, if not strictly observed, could result in damage to, or destruction of, equipment or loss of mission effectiveness.

Note Highlights an essential operating or maintenance procedure, practice, condition, or statement.

In accordance with MIL-STD-38784, unless otherwise specified in the detail specification, warnings and cautions shall typically precede the text but follow applicable paragraph heading. Notes can precede or follow applicable text, depending on the material to be highlighted. Warnings, cautions, and notes shall not contain procedural steps, nor shall the headings be numbered. When a warning, caution, or note consists of two or more paragraphs, the heading WARNING, CAUTION, or NOTE shall not be repeated above each paragraph. Warnings and/or cautions and/or notes shall appear in this sequence. The paragraphs shall be short, concise, and emphasize important and critical instructions.

*** WARNING ***

Looping a circuit from remote equipment will cause connection to be lost unless an alternate means of connection is available. If connection is lost and there is no alternate means of connecting, you will be unable to remove the loop without physical access to the device.

*** CAUTION ***

Looping a circuit will cause loss of connectivity for that connection. Ensure that intrusive testing is authorized and the connection is not in use.

*** NOTE ***

• This knowledge base article assumes that you have already checked the circuit status as outlined in the Troubleshooting T1/DS3/Serial Circuits knowledge base article.
• If a loop already exists on the interface you are going to be working with, you will be unable to loop it again. This loop must be cleared before continuing. If you are unable to clear the loop, it is likely that the carrier has placed a loop on the circuit within their equipment. You will need to engage them to clear the loop before continuing.
• Applying or removing a loop on a circuit generates a small amount of errors on the interface and controller. Make sure to note error counts prior to applying a loop and after clearing it.
