Appendix A: Flash Download procedure
Upon receiving the first flash data packet, a page status bar is displayed (see
Figure 23). Depending on the language files being downloaded, there are
three or four memory pages that are downloaded (three for North American,
four for Global, Eastern/Western European versions). As additional flash data
packets are received, the status bar advances to the right until the current page
is completely programmed. Once the next page starts to download, a new
page block is displayed and the status bar starts from the left again. This
process is repeated for the remaining pages. If the download was
unsuccessful, the set displays a telephone icon with an X through it. This
indicates that the flash memory is not programmed (or is corrupt) and a new
download must be done again.

Status bar
Upon completion of the flash download (all 3/4 pages have been
received), the set verifies the flash memory contents before displaying
the IDLE screen. The IDLE screen consists of the Date (Jan. 1 12:00am)
and the brandline (Nortel Networks or customer programmed logo). Up
to 25 seconds later, the switch downloads all the parameters to the set and
the IDLE screen is updated according to the switch settings (for example,
softkeys are shown, date is updated, and soft label keys are shown).
As the download occurs, various messages can appear on the system
7
terminal. A complete list of these messages is in System Messages
(553-3001-411). The most important message is the following:
