	Optional two	These ports are available when you install an EM-422 or ES-412 in the
	XFP or CX4	optional uplink module (B in the figure above). Both the EM-422 and ES-
	Ports	412 are used to connect your switch to other high-speed Ethernet
		switches for stacking in you network.
		• For EM-422 connection: Use 10 Gigabit Small Form Factor Pluggable
		(XFP) transceivers to connect 1000Base-X fiber-optic cables to these
		ports. See Section 3.1.3.1 on page 37 and Section 3.1.3.2 on page 37
		for information on installing and removing transceivers.
		• For EM-412 connection: Use 10GBase-CX4 cables to connect to these
		ports.
		See the EM-422 and EM-412 User’s Guides for more information.

	Two stacking	Connect these ports to other XGS-4728F switches for stacking using
	ports	stacking cables.

	Management	Connect to a computer using an RJ-45 Ethernet cable for local
	Port	configuration of the Switch.

	Console Port	Only connect this port to your computer (using an RS-232 cable) if you
		want to configure the Switch using the command line interface (CLI) via
		the console port.

Make sure you are using the correct power source as shown on the panel and that no objects obstruct the airflow of the fans.

Use the following procedures to connect the Switch to a power source after you have installed it.

Note: Check the power supply requirements in Chapter 50 on page 393, and make sure you are using an appropriate power source.

Keep the power supply switch and the Switch’s power switch in the OFF position until you come to the procedure for turning on the power.
