8692omSF module 69You can install a 8692omSF module in both slots 5 and 6 of the 8006, 8010,or 8010co chassis to enable redundant operation. The redundant module inslot 6 can then assume the processing duties of a failing primary 8692omSFmodule in slot 5.When the 8692omSF module in slot 6 completes initialization, it recalculatesthe topology information (Layer 2 including spanning tree groups (STG),Layer 3 including routing topology using Routing Information Proctocol/OpenShortest Path First (RIP/OSPF) or Border Gateway Protocol (BGP)) forthe switch unless High Availability mode (HA-CPU flag) is enabled. InHigh Availability mode, all Layer 2 information is synchronized to theredundant CPU, which results in no interruption of network services. Formore information about High Availability mode, see Managing PlatformOperations (315545-E).The two 8692omSF modules share switch fabric functions for the switch. Ifone 8692omSF module fails, the system reverts to operation with a single8692omSF module.LEDs"8692omSF module LEDs" (page 69) shows the location of the 8692omSFmodule LEDs.8692omSF module LEDsThe Switch LEDs and the CPU LEDs serve as a bar graph to indicate cardactivity. The Switch bar graph increases as the switch fabric utilizationincreases. The CPU bar graph increases when the CPU is activelyperforming tasks, such as learning media access control (MAC) addresses,updating routing tables, or interacting with the device management station."8692omSF module LEDs" (page 70) describes the 8692omSF moduleLEDs.Nortel Metro Ethernet Routing Switch 8600Installation — ModulesNN46220-306 02.02 Standard4.2 7 July 2008Copyright © 2005-2007, Nortel Networks.
