CAUTION:
All system resets (except planned interchanges) are service affecting, with
higher levels being increasingly destructive. Some resets may take up to
one half hour to complete. Certain conditions may result in a higher reset
level than the one requested. Unless you are experienced with resetting a
system, follow normal escalation procedures.

NOTE:
reset system interchange, used to switch control of the system from an
active SPE to the standby, is discussed separately under its own heading.

This command resets a Switch Processing Element (SPE) at a specified level that
is increasingly disruptive as the reset level increases.

All system resets (except
reset system interchange) are disruptive and terminate the G3-MT login.
When the command is entered, the MSS devices are checked to see if they are
currently in use. If any command or maintenance process that accesses the MSS
is in progress, the reset is denied and a message is displayed. In this case, the
contention-override option is required to force the reset. This check prevents
aborting of a save translation or other MSS process.

If the vector bit is set to trigger a core dump for the specified reset level, a copy
of system memory is first written to the primary MSS device. The system then
clears the vector and proceeds with the request. If the vector is set for an active
SPE core dump for reset level 1 a reset level 2 will be performed to recover the
Packet Interface links. See the get vector command.

System software will generally not escalate a demand system reset to a higher
level. There are certain conditions that result in a higher level reset than that
requested. These include the following:

A PNC interchange is already in progress.

A change in translation administration is in progress.
Reset levels greater than 1 turn off shadowing in a duplicated system, and leave
the standby SPE in an unrefreshed condition for several minutes.
