SPE-Down Mode
Severe problems with components of the SPE may render a non-duplicated
system incapable of call processing and other normal operations. When this
happens, the system enters SPE-down mode and software is no longer in control.
If the SPE is duplicated, this situation only occurs when
both
SPEs have fatal
faults. Otherwise, if one SPE goes down, an interchange will occur and the
system will run on the newly active SPE.
SPE Locked Standby or Standby SPE-Down
The SPE-down interface can be useful when repairing a standby SPE on a
duplicated system. For example, if handshake communication is down, this is the
only way to communicate with the standby SPE. Or, if a circuit pack on the
standby has been replaced, this interface allows you to test both that circuit pack
and the rest of the standby SPE before unlocking.
When the standby SPE on a duplicated system is down, or locked by means of
the SPE-Select switches, it is no longer in communication with the active side,
and the system is functionally unduplicated. In this state, the normal
Maintenance User Interface is unavailable to the standby SPE. You can use the
SPE-down interface to test the standby SPE and verify its health before rebooting
or unlocking. A test of all SPE boards takes only a short time and ensures that all
problems have been fixed and the SPE is ready to return to service.
Bringing Up the SPE-Down Interface
When SPE-down mode is in effect, the red LED will be lit on the Processor circuit
pack and the system will present the following message:
An alarm-notification call already in progress will preempt input from the terminal.
When the call is completed or dropped, the system displays the results of the call
and a welcome message with one of the following prompts, indicating which SPE
is currently connected to the terminal.
