68 Metro Ethernet Routing Switch 8600 modules
8692omSF module
Do not use any software prior to Metro Ethernet Routing Switch 8600
Release 3.6 with the 8692omSF CPU module. For more information, see
Nortel Metro Ethernet Routing Switch 8600 Important Notice — Using the
Correct Software Version for the 8692SF CPU Module (NN46220-404).
The 8692SF module is equivalent to the 8692omSF module. It can be used
as Metro Ethernet switch fabric with the appropriate software. See Nortel
Metro Ethernet Routing Switch 8600 Important Notice — Using the Correct
Software Version for the 8692SF CPU Module (NN46220-404).
The 8692omSF module uses a CPU similar to the PowerPC CPU of the
8691omSF. The 8692omSF CPU has 256 MB of synchronous dynamic
random access memory (SDRAM) for forwarding tables, and 56 MB of
onboard flash memory for configuration, image and log file storage.
The 8692omSF is capable of supporting an optional Metro Ethernet
enhanced CPU daughter card. The Metro Ethernet enhanced CPU
daughter card is a mezzanine daughter card consisting of dual 1 GHz
PowerPC processors. Installing the daughter card on an 8692omSF module
offloads processor intensive tasks from the 333 MHz processor located on
the 8692omSF CPU motherboard. The Metro Ethernet enhanced CPU
daughter card is required for Provider Backbone Transport (PBT) services.
For installation instructions, see
Appendix "Installing the Metro Ethernet
enhanced CPU daughter card" (page 135) .
The flash memory is divided into two volumes: Volume/0 has a capacity of
16 MB and Volume/1 has a capacity of 40 MB. You can use either volume
to store multiple file types, however, the 8692omSF module can only use
either Volume/0 or Volume/1. By default, the system can only use 16 MB on
Volume/0. If you want to use 40 MB on Volume/1, refer to the procedure
for upgrading the flash memory to 40 MB in Nortel Metro Ethernet Routing
Switch 8600 Upgrading — Software Release 4.1 (NN46220-402).
Using the SMLT protocol in the core, the Metro Ethernet Routing Switch
8600 can provide over 1 Tb/s of core switching capability.
