From the VT100 interface, access the diagnostics monitor by typing these
characters in rapid succession:
Press Ctrl-D to invoke the DO menu and select D=Diagnostics.

Type
nvramclear
to clear any differences in NVRAM memory before and
after the upgrade. After the Ascend unit clears NVRAM memory, it
automatically resets.

The unit resets a second time to load the configuration from flash memory.
This completes the upgrade.
Note:
You can also restore your configuration from the text file saved on your
hard disk. If you are not sure how to restore a configuration, see the section on
restoring a configuration in the documentation.
Upgrading standard load using TFTP
1
Obtain the correct binary from ftp.ascend.com/pub/Software-Releases/
Pipeline. Place the binary in a TFTP boot directory accessible via the
Ethernet. Be sure the TFTP server is running. Be sure you know the IP
address or host name of the server.
2
From the Pipeline VT100 interface, press Ctrl-D to invoke the DO menu and
select D=Diagnostics.
3
At the
>
prompt, type:
tload
hostname filename
where hostname is the name or IP address of your TFTP server (which is
your computer or a server on your LAN that has a TFTP server program
running), and filename is the name of the binary that you placed in your
TFTP server’s boot directory.
For example:
tload hummer b2.p75
or
tload 192.168.100.2 b2.p75
loads b2.p75 into the Pipeline from a host named hummer, or loads b2.p75
into the Pipeline from a host with an IP address of 192.168.100.2.
