LEDs on the Generation 2 Switching Modules

Table 1-13describes the LEDs for the 48-port, 24-port, and 12-port 4-Gbps Fibre Channel switching modules and the 4-port 10-Gbps Fibre Channel switching module.

Table 1-13		LEDs for the Cisco MDS 9000 Family Generation 2 Fibre Channel Switching Modules
LED	Status		Description
Status	Green		All diagnostics pass. The module is operational
			(normal initialization sequence).
	Orange		One of the following occurs or occurred:
			• The module is booting or running diagnostics
			(normal initialization sequence).
			• The inlet air temperature of the system has
			exceeded the maximum system operating
			temperature limit (a minor environmental
			warning). To ensure maximum product life, you
			should immediately correct the environmental
			temperature and restore the system to normal
			operation.
	Red		One of the following occurs or occurred:
			• The diagnostic test failed. The module is not
			operational because a fault occurred during the
			initialization sequence.
			• The inlet air temperature of the system has
			exceeded the safe operating temperature limits of
			the card (a major environmental warning). The
			card has been shut down to prevent permanent
			damage.
Link	Solid green		Link is up.
	Intermittent		Link is up (traffic on port).
	flashing green
	Solid yellow		Link is disabled by software.
	Flashing		A fault condition exists.
	yellow
	Off		No link.

32-Port 2-Gbps Fibre Channel Switching Module

The 32-port 2-Gbps Fibre Channel switching module can be used to allocate bandwidth optimally. The module is organized into eight four-port groups. Only the first port in each four-port group can be an ISL. If the first port is an ISL, the other three ports in the group are disabled. The four ports within a port group share a single internal channel resulting in a subscription ratio of approximately 3.2 to 1. The

32-port 2-Gbps switching module provides more ports at a lower price per port. Figure 1-25shows a 32-port switching module.
