Configuring System Information 161
Using DHCP and TFTP servers require the following preparations:
•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-VRTX.txt that contains
VRTX\VRTX-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 PowerEdge VRTX
value). It should be written from right to left. 674=02 a2
• 15 — Data Length
• 01 — Sub option code 1 (Dell PowerEdge VRTX value)
• 13 — Sub option length
• Conversion of the file name (in the above example: conversion of
indirect-VRTX.txt from ASCII to HEX - 69-6E-64-69-72-65-63-
74-2D-63-6F-6E-74-61-78-2E-74-78-74
Auto Update of Configuration/Image File
To set the auto update and configuration parameters:
NOTE:
For the automatic options in this page to work the following must be
implemented:
• Since Auto-Config depends on retrieving information from a DHCP server, the
startup configuration needs to include a DHCP IP interface. The device is
defined as a DHCP client, as described in
IPv6 Interface or IPv4 Interface . After
reboot, this command is not saved in the Startup configuration.
• Preparations described above must be completed on the DHCP server and
TFTP servers.
