Downloading and Broadcasting Firmware
5-8 Verilink NCM 2000
Broadcasting Firmware
If the NCM is not to be updated, but rather modules which it
controls are to be updated, the procedure outlined above may still
be used to FTP new code into the NCM. Then, instead of writing the
file to flash memory the file will be broadcast across the shelf.
Firmware is downloaded to the Bpartition. The Apartition can be
upgraded only by a field upgrade of the RAM chip.
A message is contained in the header of the download file that
identifies which type of module the file is intended to upgrade.
Other modules that may be in the node ignore the download file.
A minimum of privileged user password status is required to
exercise a broadcast.
To minimize errors and facilitate a quicker download, disconnect
the Ethernet port prior to initiating the download.
Cautions The Download Firmware Menu functions are subject to these
considerations:
• TABS-based cards do not support the ACP Broadcast Results
option or any of the other commands beginning with ACP.
• If a node contains a mix of TAC 2130 or TAC 2130-S cards as
well as TAC 2130-T cards, do not use the TABS download
option. TAC 2130 and TAC 2130-S cards use a different
firmware file than TAC 2130-T cards. A TABS download in a
mixed shelf will damage the cards for which the file is
incorrect, requiring factory repair.
• NCM releases 4.14 and newer do not support the broadcast
results function for DIDCSU or DCSU modules with firmware
earlier than version 2.14.
• If the ACP Broadcast Results option is used before a broadcast
has been done, the information shown will apply only to the
status of code in the NCM module(s).
• During a download, ACP Broadcast Results cannot be used.
Wait for the download to finish.
• The ACP Broadcast Results option shows the results of ACP
broadcast downloads only. If a specific shelf/slot has been
targeted by use of the Card Retransmit function, those results
are not shown in the broadcast result screen.
• Each time Card Retransmit is used on a card, it will force a
download to that card, even if a retransmit to that card has
already been requested.
• When using the Card Retransmit option to resend to a number
of cards, avoid entering a command string longer than 128
characters. Any input after the 128th character will be lost.
