		receiving power.		You can do the following:
				• Make certain that the

				For more information, refer to
				“Installing BigIron RX-4

				“Installing BigIron RX-8
				modules” on page 38, and
				“Installing BigIron RX-16

				power supplies in a BigIron
				RX-4 chassis” on page 30,
				“Installing power supplies in
				the BigIron RX-8 chassis” on
				page 40, and “Installing
				power supplies in a BigIron
				RX-16 chassis” on page 50.
				• Check the Pwr LED on the
				management module. If it is
				on, this module may be
				holding the power from the
				interface module.
				• Enter the show chassis
				command at any level of the
				CLI to determine if the
				management module
				recognizes the presence of
				all power sources.
				• If using AC power supplies,
				see the entry for the AC
				power supply LED in this
				table for more information.
