Standard Local Download

4. Store the hex image file in the /tftpboot directory as sehi.hex.

NOTE

This 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 a UNIX workstation, contact Cabletron Systems Technical Support.

5.Edit the /etc/inetd.conf file by removing anything prior to the tftpboot daemon (e.g., the # sign) that comments-out the line.

6.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

You must request a process status and grep for inetd to obtain the process ID number (refer back to step 3 in this procedure).

B.2 STANDARD LOCAL DOWNLOAD

Table B-1 provides a step-by-step procedure for downloading the firmware image file. This section provides specific MIB OIDs, their names, and the required setting for proper image file download. Refer to your specific MIB walking tool documentation for instructions on how to set MIB OID strings.

The Download OIDs for Cabletron Systems products reside in the 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:

•You must follow the steps in order.

•Enter the IP address of the TFTP server in standard dotted decimal notation (e.g., 132.177.118.24).

•Enter the FULL path to the image file in the ctDLTFTPRequest OID, including the name of the image file (e.g., c:\tftpboot\sehi.hex).
