Overview SCC firmware can be upgraded by using FTP to transfer the new
executable files into the card. The procedure will vary according to
what version is currently installed and what new code version is to
be used.
In most cases it is advisable to download new versions of SCC code
to flashbank B only, leaving the original code as shipped in
flashbank A. In this way the user is always able to fall back to the
known code revision if a problem is noted with the upgrade.
Due to increases in file size, since version 1.81 of SCC firmware,
the executable is distributed in compressed form. After the code
has been transferred to the SCC using FTP it must be
decompressed. Earlier versions of SCC code do not have the needed
routines to do this decompression. Therefore, when upgrading
from a version below 1.8x to 1.8x or higher, one must first
download a new compile of SCC version 1.69C to flashbank A.
This will enable the decompression of the new code.
Two procedures are documented below. The first is used to get
version 1.69C into flashbank A in order to allow subsequent
download of compressed code. This need be done only if the
firmware currently in flashbank A is a release prior to version 1.81
(other than 1.69C). The second is a general procedure used to
download new code to flashbank B.
Downloading
Version 1.69C to
Flashbank A
Use this procedure only if the firmware currently installed in the
SCC 2020 is any revision earlier than 1.81, except 1.69C.
The top line of the SCC 2020 Main Menu indicates which version of
firmware is currently running and the second line indicates which
flashbank the current firmware was loaded from. To determine
which version of firmware is in the other flashbank, use the boot
option on the Node Administration Menu and select that
flashbank.
If the SCC 2020 already has version 1.81 or newer or version 1.69C,
skip to the section labeled “
Upgrading Flashbank B ”.
You will need to
know
• The IP address of the FTP server.
• The absolute path to the directory containing the Verilink SCC
upgrade file (FLASH.A_U in this case).
• The password, if required, for accessing the FTP server.
Step By Step 1. Using either direct connection to the Craft port, or Telnet,
open a Craft session to the SCC card to be upgraded.
2. Use the “O” command to select the Node Administration
Menu.
3. Type “B” to reboot.
