Table 9. 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
		network device, or the LEDs are turned
		off. To turn on the LEDs, use the eco-
		friendly button.
	Solid green	The SFP or SFP+ transceiver has
		established a link at 1000 Mbps or 10
		Gbps to a network device.
	Flashing	The SFP+ transceiver is receiving or
	green	transmitting packets to a network device
		at 10 Gbps. (The LED does not flash for
		activity at 1000 Mbps.).

SFP+ slots 27 and 28 on the 28-port switches and slots 51 and 52 on the 52-port switches may be used as stacking slots to build a VCStack of up to four switches. For background information, refer to the x510 Series Installation Guide for Virtual Chassis Stacking. Table 10 defines the LED states when the slots contain stacking transceivers.

Table 10. Stacking Slot LEDs

LED	State	Description
Link/Activity	Off	The slot is empty, the stacking transceiver
		has not established a link to a network
		device, or the LEDs are turned off. To turn
		on the LEDs, use the eco-friendly button.
	Solid green	The stacking transceiver has established
		a 10 Gbps link to another switch in the
		stack.
	Flashing	The stacking transceiver is receiving or
	green	transmitting packets.

The Switch ID LED, shown in Figure 10 on page 39, 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 5, “Powering On the Switch” on page 69 has the procedure for verifying and, if necessary, changing the ID number of the switch.
