Switching Modules Chapter 1 Product Overview LEDs on the Generation 2 Switching Modules Table 1-4 describes 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 1-4 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 yellow A fault condition exists. 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 3.2:1. The 32-port 2-Gbps switching module provides more ports at a lower price per port. Figure 1-13 shows a 32-port switching module. 1-16 Cisco MDS 9200 Series Hardware Installation Guide OL-16188-01
