Alarm LED
The ASA 5500-X performs autonomous environmental monitoring, polling all external sensors and monitoring
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 CLI commands.
Note: If you remove one of the power-supply modules from an ASA with redundant power supplies—in other
words, one with two power supplies installed—the Alarm LED will light. To turn off the light, you must power-cycle
the chassis; that is, turn it completely off and then turn it back on. See Power Supply, page 18 for more information
about the redundant power-supply configuration. See Remove and Install the Power Supply, page 59 for more
information about removing a power supply.
ASA 5500-X I/O Cards
The ASA 5500-X six-port GigabitEthernet interface cards extend the I/O capabilities of the ASA 5525-X,
ASA 5545-X, and ASA 5555-X models by providing additional GigabitEthernet ports.
The I/O cards provide the following benefits:
 Segmentation of network traffic into separate security zones
 Fiber-optic cable connectivity for communications over long distances
 Load-sharing of traffic, and protection against link failure, using EtherChannel
 Support for Jumbo Ethernet frames of up to 9000 bytes
 Protection for Active/Active failover, and for full-mesh firewall deployments against cable failure
For information about installing an I/O card in your ASA, see Chapter 6, “Maintenance and Upgrade Procedures
for the ASA 5500-X.”
SFP Modules
The ASA uses field-replaceable small form-factor pluggable (SFP) modules to establish Gigabit Ethernet
connections.
Use only Cisco-certified SFP modules on the ASA. Each SFP module has an internal serial EEPROM that is
encoded with security information. This encoding allows Cisco to identify and validate that the SFP module meets
the requirements for the ASA.
