Cabletron Systems SEHI-22FL manual B.2 STANDARD TFTP DOWNLOAD

Standard TFTP Download

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.

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.

NOTE

The user must request a process status and grep for inetd to obtain the process ID number (refer to step 3).
