Alarm

Meaning

Troubleshooting Steps

Alarms Cleared

Current alarms have been
cleared by user.

Information only.

Card Config Failed

Cannot upload configuration
data to a card.

Information only. Could indicate a
potential problem. You may need to
reset the card.

Card initialized.

Information only.

Card Reconfig
Failed

Reconfiguration of the card
failed

Information only. Could indicate a
potential problem. You may need to
reset the card.

Card Reconfigured

Card is reconfigured.

Information only. Could occur when
the card is plugged in or the system is
powered up.

Communication
Failed

Error during communication
between MCPU and a slot.

Replace the unit.

DS3/E3/OC3/CBR/
IMA/VCM Ref Clk
Failed

Interface clock has been
designated as the system clock,
and the interface clock has
failed.

Check the physical connection. Check
for other alarms such as
LOS/LOF/LOCD. Check the physical
connection.

Fan #1 failed

Replace the fan tray.

Fan #2 failed

Replace the fan tray.

History Overflowed

Alarm history table has
overflowed. Alarms will
continue to be recorded but
will displace oldest alarms.

Clear the history alarms table through
NMS or Telnet.

Id Prom Checksum
Error

The internal checksum on the
idprom of the indicated card is
incorrect.

Have the idprom replaced with the
correct version. The system takes no
action if it recognizes the proper card
ID.

Invalid DB Cardtype An unknown card type is

found in the database

Information only.

Failed log -in. Someone failed
to log in to the shelf three
successive times.

Information only.

Loss 8KHz Ref
Clock

The system reference clock was
lost.

Try reassigning the clock—especially to

internal

New Card
Configured

Configuration data for a new
card is uploaded.

Information only. The card was not
stored in the database.

PWR Supply Failed

Power supply has failed.

Replace the power supply with an
operating unit.

Queue 0 Over
Threshold

The congestion threshold for
Queue 0 was exceeded.

Check and correct VC connections.
Check and adjust VI shaper values.
Check and adjust incoming traffic
volume. Check for faulty IMA links,
which may reduce traffic handling for a
group.
