MSS User Guide 8: Updating Software

attempts. The MSS will then try TFTP, NetWare, and MOP booting (in that order)
provided that it has enough information to try each download method.
Downloading and rewriting the Flash ROM will take approximately two minutes
from the time the Initialize command is issued. If the download file cannot be
found or accessed, the MSS can be rebooted with the code still in Flash ROM.
The OK/ACT LED will blink quickly while the MSS is booting (and reloading
code) and then slowly when it returns to normal operation.
Note: If you experience problems reloading Flash ROM, refer to Troubleshooting
Flash ROM Updates.
FTP
1. Use an FTP client to open an FTP session to the IP address of the MSS.
2. Log in with the username of root.
3. Enter the privileged user password (the default is system).
4. Make sure your FTP client is set to do a binary transfer.
5. Stay in the same directory; the default login directory is the correct directory.
6. Do an FTP Put of the MSS***.sys file (for example, MSSVIA.x.sys for the
MSS VIA).
Once the file is downloaded, the MSS writes the file to Flash (this takes a few
moments) and then automatically reboots. After rebooting, the unit runs the new
firmware.
TCP/IP
Before the MSS downloads the new software, it will send DHCP, BOOTP, and/or
RARP queries (all are enabled by default). Next, the MSS will attempt to
download the MSSxxx.SYS file using TFTP (Trivial File Transfer Protocol).
If a host provides DHCP, BOOTP, or RARP support, it can be used to set the
MSS IP address (all methods) and loadhost information (BOOTP and RARP
only).
Some BOOTP and TFTP implementations require a specific directory for the
MSSVxxx.SYS file. See your host's documentation for instructions.
To manually configure the MSS IP parameters for software reload, use the
following commands.
