computer using a web browser (Internet Explorer 5.0 or above, or
Netscape Navigator 6.2 or above), or from a network computer using
SNMP network management software.
Note: The onboard program only provides access to basic configuration
functions. To access the full range of SNMP management
functions, you must use SNMP-based network management
software.
Stack Operations
Up to eight 24-port or 48-port Gigabit switches can be stacked together as
described in the Installation Guide. One unit in the stack acts as the Master
for configuration tasks and firmware upgrade. All of the other units
function in Slave mode, but can automatically take over management of
the stack if the Master unit fails.
To configure any unit in the stack, first verify the unit number from the
front panel of the switch, and then select the appropriate unit number
from the web or console management interface.
Selecting the Stack Master
Note the following points about unit numbering:
• When the stack is initially powered on, the Master unit is designated as
unit 1 for a ring topology. For a line topology, the stack is simply
numbered from top to bottom, with the first unit in the stack
designated at unit 1. This unit identification number appears on the
Stack Unit ID LED on the front panel of the switch. It can also be
selected on the front panel graphic of the web interface, or from the
CLI.
• If more than one stack Master is selected using the Master/Slave push
button on the switch’s front panel, the system will select the unit with
the lowest MAC address as the Master.
