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:
• Power Supply Redundancy
• Hot-Swapping
• Hardware Monitoring
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 guidelines apply to the various modules. In some cases a reboot is required. Refer to
“Hot-Swapping Plug-In Modules” on page 2-24 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.”
