A re t u r n cable from this unit’ s Cascade A Out connecto r to the adjacent unit’ s Casca de A In connector completes the stack connection (see the e xample shown in Figure 3 ). Figure 3. Connecting Casca de Cabl[...]

7 Base Unit Descr iption The base unit is a unique stack un it that can be selected by the Unit Select switch o n the front -panel of the 400-ST1 cascade module. One unit in th e stack configuration must be assigned as the bas e unit; all other units in the stack must have t heir Unit Select switch set to Off (see “ Un it Select Switch ” on pag[...]

8 • Stack IP MA C address --- The s tac k IP MAC add r ess is automatically assigned during the stack in itialization: The base unit’ s MA C address, with a softwar e offset, is used for the stack IP MA C address. For e xample, if the base unit’ s MA C address is: 00-00-8 2-99-44-00 and the Stack s oftware of fset is: 1F then the Stack IP MA [...]

9 • T emporary Base Unit --- If an assigned base unit fails, the next unit in the stack order automatically becom es the new temp or ary b ase unit . This change is ind icated by the Base LED on the temporary base unit’ s LED displa y panel turn ing on (ye llow). The automatic base unit chan ge to the ne x t un it in the stack order is a temp o[...]

10 Stack Configurations As sho w n in Figur e 4 , the cascade connectors and cables on the 400-ST1 front-panel provide the ability to stack up to eight BayStack switches. W ith 400-4TX MD As installed in each switch, the stack can accom modate a maximum of 224 switch p orts. Because stack par ameters are associated with th e base unit (see “ Bas [...]

13 Certain n etwork m anagement station (NMS) applicatio ns assume a stack do wn configura tion for the graphical user interface (GUI) that represents the stack (see Figur e 5 on page 12 ). F or this reason, Bay Netwo rks recom mends that you alw ays configu re the top unit in the stack as the base unit. In any stack configuration, the follo win g [...]

14 Redundant Cascade Stacking Feature BayStack 400-ST1 Cascade Modules allo w you to connect up to 8 units into a red undant cascade stack. If any single unit fails or if a cable is accidently disconnected, other units in the stack remain o perational, without int erruption. Figur e 6 shows an e xample of ho w a stack conf iguration reacts to a fai[...]
