Management 0/0 Interface
You manage the ASA through the Management 0/0 interface. The Management 0/0 interface has the
following characteristics:
• No through traffic support
• No subinterface support
• No priority queue support
• No multicast MAC support
• The IPS or CX SSP software module and the ASA share the Management 0/0 interface; however,
each has its own separate MAC address and IP address. You must configure the module IP address
within the module operating system. However, you configure physical characteristics (such as
enabling the interface) on the ASA.
The Management 0/0 interface is configured for management-only traffic, and you cannot disable
management-only for the Management interface. Also, because the ASA 5500-X models do not allow
subinterfaces on the Management interface, for per-context management, you must connect to a data
interface for management.
The Management 0/0 interface is configured for ASDM access as part of the default factory
configuration.

Alarm LED
The ASA 5500-X series chassis perform autonomous environment monitoring to poll all external sensors
and monitor operating conditions. In the event of damage to certain internal components or surpassed
temperature thresholds, the system activates an alarm LED to notify you of a critical condition. For
example, the alarm LED is activated by firmware in the event of various critical over-voltage and
over-temperature conditions, as well as when the ASA has missing or unrecognized internal chip
components. When the alarm LED lights, you can find details about the system condition from the
system message that appears on the console or by entering the show environment or show controller
pci command.
