2.7.278 MEM-LOW
The Memory Gone alarm occurs when data generated by software operations exceeds the memory
capacity of the TCC2/TCC2P. The TCC2/TCC2P cards which exceed the memory capacity reboot to
avoid failure of card operations.
The alarm does not require user intervention. The MEM-LOW alarm always preceeds the MEM-GONE
Note
alarm.
2.7.278 MEM-LOW
The Free Memory of Card Almost Gone alarm occurs when data generated by software operations is
close to exceeding the memory capacity of the TCC2/TCC2P. The alarm clears when additional memory
becomes available. If additional memory is not made available and the memory capacity of the card is
exceeded, CTC ceases to function.
The alarm does not require user intervention. If the alarm does not clear, log into the Technical Support
Note
Website at http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447.
2.7.279 MFGMEM
The Manufacturing Data Memory Failure alarm occurs when the EEPROM fails on a card or component,
or when the TCC2/TCC2P cannot read this memory. EEPROM stores manufacturing data that a system
TCC2/TCC2P uses to determine system compatibility and shelf inventory status. Unavailability of this
information can cause less-significant problems. The AIP EEPROM also stores the system MAC
address. If the MFGMEM alarm indicates EEPROM failure on these panels, IP connectivity could be
disrupted and the system icon is grayed out in CTC network view.
When you lose LAN connectivity with an ONS 15454 due to an MFGMEM alarm on the AIP, you can

reestablish node management by disconnecting the Ethernet cable from the panel and connecting it to
the active TCC2/TCC2P LAN port.
