Stack Operation

V1.1.0 or later provide fail-safe stackability when you install the optional
BayStack 400-ST1 Cascade Module. You can connect up to eight switches to
provide uninterrupted connectivity for up to 224 ports (see
“Fail-Safe Stack
Application ” on page 1-22 ). 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).
