Appendix A: Flash Download procedure

January 2002

Nortel Networks strongly recommends that you not force load an overlay
(load with a Suspend option) unless there is an emergency while PSWV
is in progress. In this instance, existing PSWV logic aborts downloading
for the current PSWV block (of cards or sets of a given type being
downloaded) and restarts the download for that block and remainingones
after the overlay is exited. If this happens to M3900 flash download, the
block of sets are out-of-service for a lengthy period of time and this
prolongs the completion of the system-wide flash download.
•
If system warm-start (Initialization) or cold-start (Sysload) occurs while
flash download is in progress, the download process is aborted abruptly.
Any sets which are in the middle of download fail to complete firmware
download and are left inoperable. You must re-enter the single-set or
system-wide flash download command later to restart and complete the
download. For system-wide downloads, any previously scheduled sets
are no longer queued for download.
•
While a manual individual download operation is still in progress, do not
abort Overlay 32 (except in an emergency) by using the **** command.
If the overlay is aborted before completingthe download, the set is left
inoperable until a flash download command for the set is re-entered and
completed at a later time.
•
Duringsystem wide download, you can use all overlays by issuingthe
ld x susp command. However, this ungracefully stops the download to
the current group of sets that are being downloaded and leaves them
without firmware until the overlay is exited. The download to these sets
is then started again.
•
While a system-wide flash download operation is in progress:
— Service change (CHG, MOV, or OUT) to a unit that is currently
beingdownloaded is blocked in Overlay 11. An SCH1958 message
is printed.
— Move (MOV) or remove (OUT through LD 11 or Automatic Set
Relocation) to an M3900 set before its flash download starts
prevents download to the set in this cycle of system-wide flash
download.
— A new M3900 set added (throug h LD 11 or Automatic Set
Relocation) after the FDLS command is issued is not included in this
round of system-side download.
