Software Rollback
Software rollback (also referred to as image rollback) essentially allows the OmniSwitch 6600 Family
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 Family 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:
• OS6600-BPS Back Up Power Supply
• OS6600-GNI-C2 Gigabit Ethernet Uplink Submodule
• OS6600-GNI-U2 Gigabit Ethernet Uplink Submodule
• MiniGBICs installed in the OS6600-GNI-U2 Gigabit Ethernet Uplink Submodule on OS6624, OS660-
U24, OS6600-P24, and OS6648 switches or the built-in MiniGBIC slots on OS6602-24 and OS6602-
48 switches; MiniGBICs include:
- MiniGBIC-SX
- MiniGBIC-LX
- MiniGBIC-LH-70
• 100 Mbps SFPs installed in the OS6600-U24; SFPs include:
- SFP-100-LC-MM
- SFP-100-LC-SM15
- SFP-100-LC-SM40
- SFP-100-MTRJ-MM
Note. Stacking modules cannot be hot swapped at any time. For information on stacking modules, refer to
Chapter 2, “OmniSwitch 6600 Family Chassis and Hardware Components.”
For instructions on hot swapping back up power supplies, uplink modules, and MiniGBICs, refer to
Chapter 2, “OmniSwitch 6600 Family Chassis and Hardware Components.”
