OmniSwitch 6900 Availability Features
The switch provides a broad variety of availability features. Availability features are hardware and software-based safeguards that help prevent the loss of data flow in the unlikely event of a subsystem failure. In addition, some availability features allow users to maintain or replace hardware components without powering off the switch or interrupting switch operations. Combined, these features provide added resiliency and help ensure that the switch is consistently available for day-to-day network operations.
Hardware-related availability features include:
•
•
•
•
Smart Continuous Switching
Power Supply Redundancy
For information on power supply redundancy, refer to Chapter 2, “Chassis and Power Supplies.”
Hot Swapping
Hot swapping refers to the action of adding, removing, or replacing certain hardware components without powering off your switch and disrupting other components in the chassis. This feature greatly facilitates hardware upgrades and maintenance and also allows you to easily replace components in the unlikely event of hardware failure. The following hardware components can be hot swapped:
•
Power supplies
•
Transceivers
•
Fan tray
•
Plug-in modules
Note. Hot-swapping plug-in modules applies to like modules only. If one module type (e.g., OS-XNI-U4) is being replaced with an unlike module (e.g., OS-XNI-U12) a chassis reboot is required. Refer to
Chapter 2, “Chassis and Power Supplies” for detailed information on hot-swapping plug-in modules.
For information on adding and removing power supplies and plug-in modules, refer to
Chapter 2, “Chassis and Power Supplies.”

Hardware Monitoring
Automatic Monitoring
Automatic monitoring refers to the switch’s built-in sensors that automatically monitor operations. If an error is detected (e.g., over-threshold temperature), the switch immediately sends a trap to the user. The trap is displayed on the console in the form of a text error message.
LEDs
LEDs, which provide visual status information, are provided on the front and rear panels. LEDs are used to indicate conditions, such as hardware and software status, link integrity, data flow, etc. For detailed
LED descriptions, refer to the corresponding hardware component section in the next chapter.
User-Driven Monitoring
User-driven hardware monitoring refers to CLI commands that are entered by the user in order to access the current status of hardware components. The user enters “show” commands that output information to the console. The Show commands for all the features are described in detail in the OmniSwitch CLI
Reference Guide.
