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 40.
Enterprise Device Manager always shows the physical view in a cascade down (stack down)
configuration.
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 two or more switches, use the 3-foot cascade max-return cable (AL4518002-
E6) to complete the link from the last unit in the stack to the base unit.
