CLEAR SYSTEM
EVENT LOG
Write security: 3; Read security: 5
Clears the event log. When you select the command, the following prompt
displays: This will clear the entire event log. Confirm (y/n). Select
Y
to clear the
log or
N
to exit the command.
ETHERNET PORT
Read security: 5
Displays status information about the Ethernet port. An asterisk (*) indi-
cates activity for the item. The following read-only fields are available to
review:
CLEAR SYSTEM LED
Write security: 3; Read security: 5
Changes the color of the system LED on the front panel from yellow (indi-
cating a previous error) to green (OK). The system LED turns red if the
ATLAS 550 detects a major system failure. If the failure condition clears, the
LEDturnsyellowandremainsyellowtowarnofthepastfailure.
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 70
o
Cand/orgreater
than 85
o
C. If one of these thresholds is exceeded, a warning will be placed
in the Event Log but no other action will be taken.
SYSTEM POWER
ALARMS
Read security: 5
Indicates that the -58 V and/or -24 V power supplies
are not functional. These power supplies are continu-
ously monitored to determine failures. If one of these supplies fails, a mes-
sage will be placed in the E
VENT
L
OG
(see also Event Log on page 6-4).
SYSTEM TIMING
SOURCE
Read security: 5
Indicates which timing source (primary or backup) is currently being used
by ATLAS 550 and if ATLAS 550 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 sys-
tem timing source in the S
YSTEM
C
ONFIG
menu. See Primary Timing Source
on page 6-8 and Backup Timing Source on page 6-8 for details.
If you clear the event log, you cannot retrieve the data.

TATUS
Indicates the current status of the Ethernet port.
T

F
RAMES
Indicates the number of frames transmitted from the
Ethernet port since system startup.
R
X
F
RAMES
Indicates the number of frames received on the Ethernet
port since system startup.
E

R
ATE
Indicates the data rate on the Ethernet port.
