Table 8 describes the stack down configuration illustration references.
Certain network management station (NMS) applications assume a stack down
configuration for the graphical user interface (GUI) that represents the stack (see
Figure 15 ).
In any stack configuration, the following applies:
• When you apply power to the stack, the base unit initializes and the entire
stack powers up as a single logical unit within 45 seconds.
• You can attach an RS-232 communications cable to the console port of any
switch in the stack.
• You can downline upgrade the entire stack from any switch in the stack from
the console interface, a Telnet session, the Web-based management interface,
or any generic SNMP-based network management software.
• You can access and manage the stack using a Telnet connection, the
Web-based management interface, or any generic SNMP management tool
through any switch port that is part of the stack configuration.
• When stacking three or more switches, use the longer (1-meter) cascade
max-return cable (part number 303979-A) to complete the link from the last
unit in the stack to the base unit.
Table 8 Stack down configuration description
1 Base unit
2 Last unit
3 Cascade cable (part number 303978-A)
4 Cascade max-return cable (part number
303979-A)
Note: For this reason, Nortel Networks recommends that you always
configure the top unit in the stack as the base unit.
