Alarm Information; Quick Tips - Zhone IMACS 8000 User Manual

Running Head
System Redundancy
If the user wants any single or combination of ENABLED WAN slots and/or port(s) to
generate a switch to the ALT MAP, then set the AMT TRIGGER field to ANY OF THE
ABOVE.
If all of the ENABLED WAN slot(s) and/or port(s) are desired to be in alarm before the
automatic switch to the AMT MAP, then set the AMT TRIGGER field to ALL OF THE
ABOVE. Note: Automatic switching is non-revertive and requires a manual sWitch to return
the system back to the base map configuration and operation.
SERVER CARD SETTINGS:
The RESTART P1, P2, and P3 fields select how each server card will be treated upon a switch
to the alternate map. If the field is left at the default of no, then the card will not be
automatically restarted on a sWitch. If set to yes, then the card will be restarted upon a sWitch
to or from the alternate map.

5.34.2.4 ALARM INFORMATION

There are two types of alarms associated with AMT. First is AMT ACT, which indicates that
the AMT MAP is active. Switching back to the base map clears this alarm. Second is the
SYNCAMT alarm which indicates that the installed card hardware does not match the card
configuration saved on the alternative map. This alarm informs the user that the stored AMT
MAP is now not valid for the currently running configuration, and a new AMT map must be
created using one of the two AMT map creation methods. With alarm is occurring, NO
AUTOMATIC SWITCHING can be performed until a new map is created, or the newly
introduced hardware is deleted. This alarm essentially indicates that the AMT MAP feature is
effectively disabled.

5.34.2.5 QUICK TIPS:

The Copy function makes a copy of the active configuration and stores it into the ALT MAP
memory location.
The Backup function saves a copy of the ALT MAP via TFTP only when operating during
normal BASE MAP operation.
An ALT MAP file created on a remote node may be loaded via TFTP using the rEstore
function.
The sWitch is the manual switch from the BASE MAP to the ALT MAP or from the ALT
MAP to the BASE MAP.
