x510 Series Installation Guide for Virtual Chassis Stacks

Stacking Slots
The x510 Series Switches come with two stacking slots. The slots are the
last two SFP+ slots on the switches and are labeled “S1/27” and “S2/28”
on the 28-port switches and “S1/51” and “S2/52” on the 52-port switches.
The slots have two functions. You may use them with the VCStack feature
to build a stack of x510 Series Switches or, by disabling the VCStack
feature, you may use them with regular SFP or SFP+ transceivers as
additional networking slots.
The names of the slots depend on the status of the VCStack feature on the
switch. The management software refers to the slots as “S1” and “S2”
when the VCStack feature is enabled and the slots are used with the
special stacking transceivers to create a stack.
When you disable the VCStack feature to use the slots with regular SFP or
SFP+ transceivers on a stand-alone switch, the slots are referred to as
slots 27 and 28 on the 28-port switches and 51 and 52 on the 52-port
switches. For instructions on how to disable VCStack to use the switches
as stand-alone units, refer to the
x510 Series Installation Guide for Stand-
alone Switches .
Note
When VCStack is enabled on the switch, the stacking slots only
work with the stacking transceivers in Table 10 on page 52. If you
install regular SFP or SFP+ transceivers in the stacking slots when
stacking is activated, the management software disables them and
enters an error message in the buffered log.
