System Configuration and Operation Alarms
If the CPU card is replaced with an identical CPU card but the new card has a different
firmware version, a “zip” may need to be performed.
Figure 5-15.Cold-Start NVRAM Test Screen.
WARNING!
The "Z" command will start the ZIP process. "Zipping" the system deletes all of the
information stored on NVRAM and resets it. All cards must then be completely reconfigured.
When you press “z”, the system will display the main log-in screen and ask for password
authorization from either the Manager or Operator access level. After you enter the correct
password, the system asks, "OK to Zip the system (y/n)"? Press “y” to have the system test
and re initialize itself. All NVRAM information will be erased from the Interface card, and a
new log-in screen will appear.
A new feature on the IMACS that provides for remote actions is the ability to retain the IP
information when doing a ZIP command. The ZIP command deletes all provisioning on the
IMACS. However, starting in CPU-7, the user will be prompted if they want to delete the IP
information. Choosing to not delete the information will set the unit to default, but still retain
IP connectivity. This is useful when doing remote drastic recovery on the unit. However,
caution should still be exercised. If the IMACS is accessible via the IP address over a WAN
DS0 timeslot, the WAN information is still deleted and the node will not be accessible.
Caution should always be exercised when performing the ZIP function and it is always
prudent to have someone at the IMACS location when executing a ZIP.
5.7 Alarms
Alarms warn you of problems by reporting possible system hardware or external facility
failures. The Alarm screen is accessed from the System Main Screen by pressing the "A" key
to go to the Alarm Screen (see Figure 5-16 through Figure 5-18). The Alarm Screen displays
the currently active alarms (if any) and provides access to the Alarm Filters and Alarm History
screens. Figure 5-16 shows a typical Alarm Screen with an active alarm.
