Section 3. Initial Configuration
This section describes the initial device configuration and includes the following topics:
•
General Configuration Information
•
Booting the Switch
•
Configuration Overview
•
Advanced Configuration
•
Software Download and Reboot
•
Startup Menu Functions
After completing all external connections, connect a terminal to the device to monitor the boot and other proce-
dures. The order of installation and configuration procedures is illustrated in the following figure. For the initial con-
figuration, the standard device configuration is performed. Other functions can be performed, but doing so
suspends the installation process and causes a system reboot.
Performing other functions is described later in this section.
General Configuration Information
Your device has predefined features and setup configuration.
Note
It is highly recommended to clear the browser's cache temporary files and cookies prior to upgrade of the
product with the new installed software version (e.g., in Internet Explore select Tools->Internet option,
select Delete files, check the Delete all offline content and hit OK).
Auto-Negotiation
Auto-negotiation allows a device to advertise modes of operation and share information with another device that
shares a point-to-point link segment. This automatically configures both devices to take maximum advantage of
their abilities.
Auto-negotiation is performed completely within the physical layers during link initiation, without any additional
overhead to either the MAC or higher protocol layers. Auto-negotiation allows the ports to do the following:
•
Advertise their abilities
•
Acknowledge receipt and understanding of the common modes of operation that both devices share
•
Reject the use of operational modes that are not shared by both devices
•
Configure each port for the highest-level operational mode that both ports can support
If connecting a port of the switch to the Network Interface Card (NIC) of a terminal that does not support auto-
negotiation or is not set to auto-negotiation, both the device port and the NIC must be manually set with the Web
browser interface or CLI commands to the same speed and duplex mode.
Note
If the station on the other side of the link attempts to auto-negotiate with a port that is manually configured
to full duplex, the auto-negotiation results in the station attempting to operate in half duplex. The resulting
mismatch may lead to significant frame loss. This is inherent in the auto-negotiation standard.
