LEDs for the
Stacking Slots
SFP+ slots 51 and 52 may be used as stacking slots to build a VCStack of
up to four switches. For background information, refer to Chapter 2,
“Virtual Chassis Stacking” on page 35. Table 4 defines the LED states
when the slots contain stacking transceivers.
Switch ID LED The Switch ID LED, shown in Figure 6 on page 28, displays the ID number
of the switch. A stand-alone switch has the ID number 0. Switches in a
VCStack have the numbers 1 to 4. Chapter 8, “Powering On the Stack” on
page 101 has the procedure for verifying and, if necessary, changing the
ID number of the switch.
