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:

Create a sub directory in the main directory. Place a software image

Create an indirect file that contains a path and the name of the

software version (for example indirect-contax.txt that contains

contax\contax-version.ros).

Copy this file to the TFTP server's main directory

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-contax.txt from ASCII to HEX - 69-6E-64-69-72-65-63-
