Availability Features OmniSwitch 6600 Series

Software Rollback

Software rollback (also referred to as image rollback) essentially allows the OmniSwitch 6600 series switches (in both standalone and stacked configurations) to return to a prior “last known good” version of software in the event of a system software problem. The switch controls software rollback through its resilient directory structure design (i.e., /flash/working and /flash/certified).

For detailed information on the software rollback feature, as well as the switch’s /flash/working and /flash/certified directories, refer to the “Managing CMM Directory Content” chapter in the OmniSwitch 6600 Series Switch Management Guide.

Hot Swapping

Hot swapping refers to the action of adding, removing, or replacing back up power supplies, as well as uplink modules and MiniGBICs, without powering off your switch and disrupting other components in the switch or stack. 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:

•OS66BPS-100A Back Up Power Supply

•OS6600-GNI-C2 Gigabit Ethernet Uplink Submodule

•OS6600-GNI-U2 Gigabit Ethernet Uplink Submodule

•MiniGBICs installed in the OS6600-GNI-U2Gigabit Ethernet Uplink Submodule; MiniGBICs include:

-MiniGBIC-SX

-MiniGBIC-LX

-MiniGBIC-LH-70

Note. Stacking modules cannot be hot swapped at any time. For information on stacking modules, refer to

For instructions on hot swapping back up power supplies, uplink modules, and MiniGBICs, refer to Chapter 2, “OmniSwitch 6600 Series Chassis and Hardware Components.”

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. (In the case of an over-threshold temperature condition, the chassis displays an amber TEMP LED in addition to sending a trap.)

LEDs

LEDs, which provide visual status information, are provided on the chassis front panel. LEDs are used to indicate conditions such as hardware and software status, temperature errors, link integrity, data flow, etc. For detailed LED descriptions, refer to Chapter 2, “OmniSwitch 6600 Series Chassis and Hardware Components.”
