28 CHAPTER 3: SETTING UPFORMANAGEMENT
Setting Up
Overview
This section gives an overview of what you need to do to get your Switch
set up and ready for management when it is in its default state. Detailed
procedural steps are contained in the sections that follow. In brief, you
need to:
■
Configure IP information for your Switch by completing initial Switch
setup
■
Prepare for your chosen method of management
CAUTION: To protect your Switch from unauthorized access, you must
change all default passwords as soon as possible, even if you do not
intend to actively manage your Switch. For more information on default
users and changing default passwords, see “Default Users and
Passwords” on page 44.
IP Configuration You can use one of the following methods to allocate IP information to
your Switch (essential if you wish to manage your Switch across the
network).
Manual IP Configuration
You can choose to configure the IP information yourself. The Switch
remembers the information that you enter until you change it again or
set the configuration method to Automatic.
You should use the Manual IP configuration method if:
■
you do not have a DHCP or BootP server on your network, or
■
you want to remove the risk of the IP address ever changing, or
■
it is not possible to configure the DHCP or BootP server to allocate
static IP addresses (this is necessary to ensure that the Switch is always
allocated the same IP address).
For most installations, 3Com recommends that you configure the Switch
manually. This makes management simpler and more reliable as it is not
dependent on a DHCP or BootP server, and eliminates the risk of the IP
address changing.
If you wish to manually enter IP information for your Switch, work
through the “Manual Setup” section on page 31 and connect to a front
panel port or the console port to manually configure the IP information.
