The sum of all platform weights in the stack must be no greater than 32. The total number of switches
must be no greater than 8.
Example 1: How many Summit 400-48t switches with no installed XEN or XGM 10-Gigabit option cards
can be in a stack?
Platform weight for the Summit 400-48t = 4
Let the number of switches = x
4 * x = 32
x = 32 ÷ 4 = 8
The maximum number of Summit 400-48t switches in a stack is 8.
Example 2: How many Summit 400-48t switches with installed XEN or XGM 10-Gigabit option cards
can be in a stack?
Platform weight for the Summit 400-48t = 4
Platform weight for one 10-gigabit option card = 2
Let the number of switches = x
(4 * x) + (2 * 2) = 32
4 * x = 28
x = 28 ÷ 4 = 7
The maximum number of Summit 400-48t switches with installed 10-Gigabit option cards in a stack is 7.
Example 3: Stacking eight Summit 400 series switches with Summit XEN option cards.
In a stack with two Summit 400-48 switches containing Summit XEN cards to provide high-speed
20-Gbps uplinks, how many Summit 400-24 switches can be added to the stack?
Platform weight for Summit 400-48 = 4
Platform weight for Summit XEN option card = 2
Platform weight for the Summit 400-24 = 2
Let the supported number of slots of Summit 400-24 switches in this configuration = y
