The LEDs are described in Table 3.
LEDs for the
Stacking Slots
SFP+ slots 27 and 28 on the AT-x510-28GTX Switch and slots 51 and 52
on the AT-x510-52GTX Switch 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 30, 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 7, “Powering On the Stack” on
page 79 has the procedure for verifying and, if necessary, changing the ID
number of the switch.
Table 3. SFP+ Slot LEDs
LED State Description
Link/Activity Off The slot is empty, the SFP or SFP+
transceiver has not established a link to a
