Question #91

A customer has purchased some Ethernet Routing Switch (ERS) 5600 switches
must integrate two ERS 5600 units into existing stack of ERS 5500 switches.
What is the procedure for the integration of the new ERS 5600?

A. Remove the AC from the stack, integrate the two ERS 5600 units into the existing 5600 set to "base unit" and one ERS 5600 set to "non base unit" set the existing ERS 5500 base unit to "non base unit" apply power to stack.

B. with power applied to the slack, change the existing ERS 5500 base unit to "Non Base Unit" in mixed stack operation Integrate the two new ERS 5600 to the stack with them set as "Base Unit" in mixed stack operation Reboot the stack.

C. With power applied to the stack, integrate one ERS into the stack as non base unit in mixed
stack operational
mode.
After the two ERS
5600 units have obtained their configuration from the ERS 5500 base unit, change the ERS 5500 to "non base unit" and set one ERS 5600 to "base unit". Reboot the switch stack.

D. With power applied to the stack, integrate one ERS into the stack as non base unit in mixed stack operational mode. Change the existing ERS 5500 base unit to "non base unit" and set the new 5600 to "base unit". Reboot the stack integrate the second ERS 5600 in mixed stack operational mode.
