There are four indicators (power, running, alarm, and signal loss) on a U1900 MTU board to reflect the status of the board,

Question

Options

• ATRUE
• BFALSE

• A
  17% (8)
• B
  83% (38)

Explanation

Option B (FALSE) is correct because the U1900 MTU board does not have four indicators as described - the actual number and naming of status indicators on the board differs from what the question states. Specifically, "signal loss" is not typically a dedicated physical indicator on the MTU board itself; signal loss conditions are instead reflected through the alarm indicator or reported via network management software.

The statement is misleading because it presents a plausible-sounding list - power, running, and alarm are indeed common indicator types on transmission boards - making it easy to accept the claim without scrutiny. However, the exact indicator count and labels matter on exams about specific hardware, and adding "signal loss" as a fourth independent LED misrepresents the board's actual design.

Memory tip: When a question gives you a tidy numbered list of hardware features, treat the count and the list itself as separate claims to verify. For the U1900 MTU, remember: three standard indicators (power, running, alarm) - signal loss is handled by the system, not a standalone board LED.
