Chapter 1 Product Overview Services Modules Send documentation comments to [email protected]. Note Software downloads are only necessary when a revision of the code is needed. The supervisor module can force a reset on the services module and controls whether power is applied to the switching module. If a single component or a set of components on the switching module fails, this failure does not disable another switching module if that is the only failure in the system. Each ASM has a hardware watchdog timer to detect most component failures. The watchdog timer resets the card if it is not serviced periodically. LEDs on the Fibre Channel Advanced Services Modules Table 1-18 describes the LEDs for the ASM. Table 1-18 LEDs for the Cisco MDS 9000 Family Fibre Channel ASMs LED Status Speed Link Status Green Orange Red On Off Solid green Steady flashing green Intermittent flashing green Solid yellow Flashing yellow Off Description All diagnostics pass and the module is operational (normal initialization sequence). One of the following occurs or occurred: • The module is booting or running diagnostics (normal initialization sequence). • The inlet air temperature of the system 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. One of the following 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 exceeded the safe operating temperature limits of the card (a major environmental warning). The card shut down to prevent permanent damage. 2-Gbps mode. 1-Gbps mode. Link is up. Link is up (beacon used to identify port). Link is up (traffic on port). Link is disabled by software.
