Yo u must ensure that the Interoperability Software Version Numbers (ISVNs) are

identical. That is, the ISVN for the BayStack 450 and 410-24T must be the same

as the ISVN for the Business Policy Switch.

You can verify your switch software version and ISVN in the sysDescr field of the

System Characteristics screen (see “

System Characteristics” on page 3-15).

Also, for correct operation in a mixed stack configuration, the Business Policy

Switch must be configured as the base unit.

You can connect up to eight switches to provide uninterrupted connectivity for up

to 224 ports (see “

Fail-Safe Stack Application” on page 1-26). The entire stack is

manageable as a single unit. Installation instructions are provided with the

BayStack 400-ST1 Cascade Module (see your Nortel Networks sales

representative for ordering information).

If you need to upgrade your BayStack 450 switches, refer to the upgrade

instructions provided in the Installing the BayStack 400-ST1 Cascade Module

guide.

Note:

If the ISVNs are different, only the units that have the same ISVN as the

base unit will form a stack.

Note:

If you do not designate the Business Policy Switch as the base unit, the

mixed stack will not operate.

Note:

BayStack 450 Switches that are configured with (optional)

BayStack 450-2M3/2S3 MDAs will not operate in a mixed stack configuration

that includes one or more Business Policy Switches.

Note:

The BayStack 400-ST1 Cascade Module will not operate with

BayStack 450 switches that are configured with BayStack 450 software

versions earlier than version V1.1.0. You must upgrade the switches to

BayStack 450 software version V1.1.0 (or later) before you install the

BayStack 400-ST1 Cascade Modules.
