Important:
Because many network management software packages use a cascade down (stack down)
configuration, Avaya recommends that you use a cascade down configuration. See Cascade
down on page 25.
The following guidelines apply for stack configuration:
• When you apply power to the stack, the base unit initializes, typically within 60 seconds,
and the entire stack powers up as a single logical unit.
• You can attach an RS-232 communications cable to the console port of any switch in the
stack to establish a console connection.
• You can perform a software upgrade on the stack from any switch using a Telnet session,
the Web-based Management Interface, or any SNMP-based management software.
• You can manage the stack using a Telnet session, Web-based Management Interface, or
any SNMP-based management software through any stack switch port.
• When you stack three or more switches, use the 1.5 m stack cable (AL3518002–E6) or
3 m stack cable (AL3518003–E6) to complete the link from the last unit in the stack to the
base unit.
