ADTRAN 1200305L1 system manual Normal condition, Failure condition, No Information Available

ATLAS 550 System Manual Section 4, User Interface Guide

SYSTEM STATUS > CHAIN PORT > CLEAR COUNTERS

Write security: 5; Read security: 5

Clears the CONTROL IN (Chain) port statistics. Press Y to activate this command.

SYSTEM STATUS > SYSTEM TEMPERATURE ALARMS

Read security: 5

Indicates that the internal temperature of the unit has exceeded normal operating limits. The two thresholds indicate that the internal temperature is greater than 70ºC and greater than 85ºC. If one of these thresholds is exceeded, a warning will be placed in the EVENT LOG (see Section 7, System Event Logging for more details) but no other action will be taken. The following status symbols are used:

[–]	Normal condition
[*]	Failure condition
[!]	No Information Available

SYSTEM STATUS > SYSTEM POWER ALARMS

Read security: 5

Indicates that the -58V and/or -24V power supplies are not functional. These power supplies are continuously monitored to determine failures. If one of these supplies fails, a message will be placed in the EVENT LOG (see Section 7, System Event Logging for more details). The following status symbols are used:

[–]	Normal condition
[*]	Failure condition
[!]	No Information Available

SYSTEM STATUS > SYSTEM TIMING SOURCE

Read security: 5

Indicates which timing source (primary or backup) is currently being used by ATLAS 550 and whether the system is locked onto this source. If the display does not indicate locked, the ATLAS 550 does not have a valid source of timing and cannot reliably transfer data. Review the current setting for system timing source in the SYSTEM CONFIG menu. See System Config > Primary Timing Source on page 79 and System Config > Backup Timing Source on page 79 for details.

SYSTEM STATUS > RESOURCE USAGE

Write security: 5; Read security: 5

Provides resource usage tracking for dynamic resources throughout the system. This includes current, average, and minimum availability for both analog and digital resources.
