Troubleshooting Upgrade Problems
After restart, the switch
stops at backup shell
prompt: pxm45>.
If the Return key is pressed at one of the auto-boot prompts
during start up, the switch stops in shell mode. Enter the reboot
command to restart the switch and avoid pressing the Return
key.
The non-active PXM45 will
not transition out of the
active init state.
One or more non-standby
AXSM or FRSM-12 cards
are in a transitional state.
A non-standby AXSM or FRSM-12 card is a standalone card,
or it is the card within a redundant AXSM/FRSM-12 pair that
is trying to go active. When a non-standby AXSM or FRSM-12
card is in a transitional state, such as the init state, the PXM45
cannot transition to the standby state. When all non-standby
cards have reached a steady (non-transitional) state, the PXM45
will transition to a steady state. Steady states include the
following: active ready, failed, mismatch, empty, empty
reserved, and standby ready.
Note When either card in a redundant AXSM or FRSM-12
pair is active, that pair is not preventing the standby
PXM45 from transitioning to a steady state. The
standby PXM45 is only affected when both cards in a
redundant pair are in a transitional state.
