Alarm Troubleshooting
Alarm Procedures
Procedure: Clear the MEA Alarm
Step 1
At the CTC shelf view, click the Inventory tab.
Step 2
Under the Hardware Part # column, if the number is 800-19856-XX, then you have a
10-Gbps-compatible shelf assembly (15454-SA-10G). Refer to the Cisco Installation and Operations
Guide for procedures to install a new fan-tray assembly (15454-FTA3).
Step 3
Under the Hardware Part # column, if the number is not 800-19856-01, then you are using an earlier
shelf assembly. This shelf assembly is not compatible with the XC10G, OC192 LR/STM64 LH 1550,
E1000-2-G, E100T-G, OC48 IR/STM16 SH AS 1310, or OC48 LR/STM16 AS 1550 cards. Remove the
incompatible cards to clear the alarm.
1.5.50 MEM-GONE
•
Major, Non-service affecting
The memory gone alarm occurs when data generated by software operations exceeds the memory
capacity of the TCC-I card. CTC will not function properly until this alarm clears. The alarm clears when
additional memory becomes available.

1.5.51 MEM-LOW
•
Minor, Non-service affecting
The free memory of card almost gone alarm occurs when data generated by software operations is close
to exceeding the memory capacity of the TCC-I card. The alarm clears when additional memory
becomes available. If additional memory is not made available and the memory capacity of the TCC-I
card is exceeded, CTC will cease to function.

1.5.52 MFGMEM (Backplane or Fan)
•
Critical, Service-affecting
The manufacturing data memory (EPROM) failure alarm occurs if the ONS 15454 SDH cannot access
the data in the EPROM. Either the memory module on the component failed or the TCC-I lost the ability
to read that module. The EPROM stores manufacturing data that is needed for both compatibility and
inventory issues. An inability to read a valid MAC address will disrupt IP connectivity and gray out the
ONS 15454 SDH icon on the CTC network view.
