Nortel Networks 2500 Series manual Temporary base unit, Cascade up stack configuration

Stack configuration 51

Cascade up stack configuration

Regardless of stack configuration, the following applies:

•When power is applied to the stack the base unit initializes, typically within 60 seconds, and the entire stack powers up as a single logical unit.

•A RS-232 communications cable can be attached to the console port of any switch in the stack to establish a console connection.

•A software upgrade can be performed on the stack from any switch using the console interface, a Telnet session, the web-based management interface, or any SNMP-based management software.

•The stack can be managed using a Telnet session, web-based management interface, or any SNMP-based management software through any stack switch port.

•When stacking two or more switches. use the 3 meters cascade max-return cable (part number AL2518003-E6) to complete the link from the last unit in the stack to the base unit.

Temporary base unit

If an assigned base unit fails, the next unit in the stack order automatically becomes the new temporary base unit. This change is indicated by the Base LED on the temporary base unit LED display panel moving to a steady amber state.
