Preparations for Firmware Image Download from TFTP
The image file download consists of the following steps:
• The switch downloads the Indirect Image File and extracts from it the
name of the image file.
Note: If the size of the image name bigger than 160 octets only the first
160 octets will be used
• If the image file version differs from the current image file version, then
the image file is loaded and the switch is rebooted.
The preparations on the DHCP and TFTP servers require the following:
• TFTP Server
– Create a sub directory in the main directory. Place a software image
file in it.
– Create an indirect file that contains a path and the name of the
software version (for example indirect-plasma.txt that contains
plasma\plasma-version.ros).
– Copy this file to the TFTP server’s main directory
• DHCP Server
– Configure the DHCP server with option -20 or 66. This is the IP
address of the TFTP server.
– Configure the DHCP server with option 125. Enter the following
information:
• A2-02-00-00 — Enterprise Number 674 (Dell PowerConnet 55xx
value). It should be written from right to left. 674=02 a2
• 15 — Data Length
• 01 — Sub option code 1 (Dell PowerConnet 55xx value)
• 13 — Sub option length
• Conversion of the file name (in the above example: conversion of
indirect-plasma.txt from ASCII to HEX - 69-6E-64-69-72-65-63-
74-2D-63-6F-6E-74-61-78-2E-74-78-74
