Recovery
There are several less severe resets available to the system that allow it to
recover from disrupting errors. The user can initiate these resets by using the
reset system
n
commands (where
n
is the reset level). These commands are
used to manually restart the system at various levels, depending on the required
test activity. The reset system commands are discussed below.
A system is reset due to a loss of power, or through:
■ Reset commands at the administration terminal.
■ Maintenance software, from which the system can reset itself. (This
process starts when certain software and hardware errors are detected by
the software.)
!
WARNING:
When the system is rebooted or reset at level 2, 3, 4, or 5, all voice
terminal and attendant console features are adversely affected.
Users should be advised of services that are lost and that, as a
result, must be reactivated. See
‘‘Removing Power’’
in this chapter.
The administration terminal display and circuit pack LEDs indicate the progress
of the recovery process. See
‘‘LED Interpretation’’
in this chapter for more
information.
The sections that follow discuss successful system resets. For each level of
reset, a typical administration terminal display is provided. Note that any
hexadecimal numbers shown in parentheses, such as
(=8B89)
, are only
examples and are subject to change.
NOTE:
If any of the diagnostic tests fail, the system may or may not function
properly, and the LMM may or may not proceed with the restart. If the LMM
does not proceed with the restart, the system goes into SPE-Down Mode. In
failure cases, the appropriate part (for example, the Processor circuit pack)
should be replaced.
NOTE:
Use and check the results of the
set/get vector
commands found in
Chapter 2, ‘‘Maintenance Commands’’
, to determine how much time should
be added for the recovery levels. Also, if an update file is applied on a
system reset, add from 30 seconds to one minute to the recovery time for
that reset.
