Alarm Procedures

14.4.90 MFGMEM

•
The manufacturing data memory failure (MFGMEM) alarm raises if the ONS 15327 cannot access the
data in the erasable programmable read-only memory (EPROM). Either the memory module on the
component failed or the XTC lost the ability to read that module. The EPROM stores manufacturing data
that is needed for both compatibility and inventory issues. The EPROM on the alarm interface panel
(AIP) also stores the MAC address. An inability to read a valid MAC address disrupts IP connectivity
and gray out the ONS 15327 icon on the CTC network view.
Procedure: Clear the MFGMEM Alarm on the AIP, Fan Tray, or Backplane
Do a software-initiated system reset on the XTC by referring to the

Note It takes approximately 30 minutes for the active XTC to transfer the system software to the
newly installed XTC. Software transfer occurs in instances where different software
versions exist on the two cards. During this operation, the LEDs on the XTC flash Fail and
then the Active/Standby LED flashes. When the transfer completes, the XTC reboots and
goes into Standby mode after approximately three minutes.
