6. Store the hex image file in the /tftpboot directory as sehi.hex.
7. Edit the /etc/inetd.conf file by removing anything prior to the tftpboot
daemon (e.g., the # sign) that comments-out the line.
8. Kill the inetd process (e.g., unix% kill -HUP ‘process ID number’),
and then restart the process (e.g., unix% inetd), to enable the revised
inetd.conf file.
B.2 STANDARD TFTP DOWNLOAD
Table B-1 provides a step-by-step procedure for downloading the
firmware image file. This section provides specific MIB OIDs, MIB
names, and the required setting for proper image file download. Refer to
the specific MIB walking tool documentation for instructions on how to
set MIB OID strings.
The Download OIDs for CabletronSystems products reside in Cabletron
Systems enterprise MIBs (group 52). The specific OIDs necessary to
perform an image file download reside in the common download group
under
ctDL (Cabletron Download). The full OID string to reach this group is
1.3.6.1.4.1.52.4.1.5.8.1.
When performing the steps in Table B-1, keep the following in mind:
• Follow the steps in order.
• Enter the IP address of the TFTP server in standard dotted decimal
notation (e.g., 132.177.118.24).
NOTE
The next step requires decompression of the zipped image file.
If you do not have a UNIX unzip utility, access to a PC with
PKUNZIP, or a way to FTP the decompressed image to your
UNIX workstation, contact Cabletron Systems Technical
Support.
NOTE
The user must request a process status and grep for inetd to
obtain the process ID number (refer to step 3).
